US
42% of people have a vitamin D deficiency
82.1% of black people
69.2% of Hispanic people.
Higher blood levels = over 33 ng/ml or 82.4 nmol/l
Lower blood levels less than 12 ng/ml or 30 nmol/l
50% lower risk of colorectal cancer
Consuming 1,000 IU (25 mcg) daily would help 50% of people reach a vitamin D blood level of 33 ng/ml (82.4 nmol/l)
Consuming 2,000 IU (50 mcg) daily would help nearly everyone reach a blood level of 33 ng/ml (82.4 nmol/l)
Taking 1,000 IU (25 mcg) of vitamin D daily reduced heart disease risk by 10%
Consuming 1,000-4,000 IU (25-100 mcg) of vitamin D daily should be ideal for most people to reach healthy vitamin D blood levels.
However, don’t consume more than 4,000 IU of vitamin D without your doctor's permission. It exceeds the safe upper limits of intake and is not linked to more health benefits

Dr. John, you have changed my life. As a black person living in the UK, you have enlightened me. I now take Vitamin D supplements religiously and I feel so confident with my health moving forward. May God bless you.
vitamin d is racist.
Remember your low on Vit D because you have an evolutionary trait that allows you to absorb and negate the harmful effects of a dieing star. Not even pulling your leg, the energy being given off by our sun is something your body has figured out how to negate the EXTREMELY harmful UV rays of. Its quite amazing, and definitley can be considered a Super Power.
@@akadopeboi yes, Africans evolved to be out in the sun all day sparsely clothed. Their skin evolved protective mechanisms to keep them from dying from sun exposure. A side effect is less vitamin D.
Have you had your levels checked? Also too much vitamin K will make your blood too thick and could cause a stroke. Get your bloodwork done at least once every 6 months, preferably every 3 months.
@@esecallum why?
Heard Joe Rogan takes 4000 IU so I upped mine to 6000 IU in case I have to fight him.
😂
LMAO ... M taking 60000 iu once a week, along with 40mg zinc daily ... I will fight u both ... Bring it on.
To much vit..D is dangerous...Please be careful not to take more than your doctor recommend...
@@venti4268 Science on that please? Why is it dangerous?
Then you should raise your daily DMT too...
I worked in a medical lab setting. We performed about 150 Vit D level assays per day. Of that number we found approximately 60% of the patients with Vitamin D level below 20 ug.I often commented about this finding between my coworkers.
how many % where above 30ng/ml?
Hair loss and thinning is my problem, and menopause depression. I started watching you during Covid and learned about the importance of Vit. D. Thank you!
I take 5,000 in daily. Since starting that dose, my hair is not falling out by the handful and, it’s finally growing longer. It really made a huge difference! I also had Covid 19 twice and had moderate cold symptoms and loss of taste and smell for only 2 days. I have you, Dr. Campbell, to thank for my better health. Next pestilence coming sooner than later and I’ll be right here, learning from you!! 🙏🌺🐝
Vitamin D
How many vitamin D should I take?
It depends on several preconditions.
1: your actual status of vitamin D
2: your body weight
3: your behavior and your skin type
1: If your actual status is to low and you start to take your dailymaintenance dose, it will take months or years until you reach a sufficient level.
2: how much you take it’s directly dependent from your bodyweight.
For example: 100 kg male needs the double daily maintenance dose then a 50 kg woman.
Due to the newest studies the level of vitamin D can be much higher than it was recommended before. (Michael F. Holick,USA)(80 ng/ml)
As a rule of thumb you are good if your daily vitamin D intake is between 70 and 90 iU per kilogram- after you have compensated your deficiency.
So for the hundred kilo man it’s between 7000 and 9000 IU/day. Daily intake is better than weekly, specially due to the immune system.
It is not possible to overdose with this amount.
A theoretical toxicity of vitamin D is a relative vitamin K2 deficiency. Therefore you have to take really high doses vitamin D over a long time.
(This is like trying to pump up a lorry tyre with a bicycle pump and being afraid of bursting it.)
Also the heavier ones need more in the beginning to compensate the deficit.
3: normally you get vitamin D from the sun.
But this works in our part of the world only between 15th of March and 15th of September.
It is in inevitable that’s the sun is standing higher than 45° cause your skin needs UVB rays to produce vitamin D.
Also the sky must be clear, -blue sky.
The skin surface should be as great as possible- uncreamed.
Suncream inhibits vitamin D production.
The time depending on your skin type it’s only between 10 or 20 minutes each side. After this time your skin will not produce more vitamin D.
In this case the skin can produce about 20,000 iU per day.
A high vitamin D level protect from sunburn. Studies have shown that higher vitamin D levels are protecting from all sorts of cancer. Some are reduced more than 90%.
Sorry my English isn’t perfect but it should do.
Dr. Guido Witt thanks very helpful
Thank you dr G
@The Ostrich Ostrich --How rude you are! Who are you to judge how long or short someone's comment should be?! There are many of us who ARE READING, and enjoy reading a detailed, informative, intelligent reply. Let go of your arrogance. In this time of tragedy, trauma & uncertainty, people need more understanding & patience & kindness.
@The Ostrich I've read it all. You just seem to be quoting something you've read somewhere, not useful.
Please try not to be rude and arrogant in future or I'm telling your mum.
Thanks a lot
This is why I love mushrooms.. just eat chestnut mushrooms and get some sun... full of D Vits!! My doctor was surprised to know that raw garlic removed a tooth abscess in 24 hours... enough to remove the tooth next day. The antibiotics I was given, failed. Nutrition saves lives. You are, what you eat!! THIS is THE most underrated and common sayings ever.
This is it.
@@SpoonFruit crush the garlic to release the fresh Allicin. I would drown the rest in honey and eat it with some food. Don't eat it on an empty stomach. Garlic is a serious medicine. Never abuse it. Just like anything really. It's not a daily intake. Just for emergencies, treatments and / or stews 😆 (edit, too much left hanging around in the mouth will burn, so be careful)
Exactly! you give what the body needs, it will give you what you want (health)
I've been eating raw garlic also and defo has helped. I'm fairly prone to chest infection and throat infections currently have my first throat infection and it's half as bad as it usually is. Thank you garlic! Hopefully help me avoid further issues the longer I take it. I've only been doing this one week.
Most docs have NO CLUE about nutrition here in the USA. Big pharma is pushed in them in med school and continues throughout their careers. 🤨☹
Thank you for your videos. I share them with everyone I know. I'm African American. I was well into my 40s before a primary care physician recommended that I get my vitamin D levels tested and to take supplements. This really needs to be part of the public health messaging in the U.S..
Thank you for this clarity! My Dad told me about you. D gives me energy! I take 5000 IU/day and I live in California :) And countless times my friends have gotten blood work done, to find out they were very low, here in Lake Tahoe Ca!
I've been personally taking 2000 UI a day (recently upped to 3000 UI) in response to the growing evidence that low levels of vitamin D resulted in more severe cases of the disease.
An unexpected side-effect that I wasn't considering was that it seems to have been improving my mood. I suspect that I was vitamin D deficient, something it seems my doctor hadn't really considered when attempting to treat my depressive episodes.
Is it possible that there's an element of placebo in relation to your mood state?
Could it be the belief that it's making you better, is......
making you better?
(Not knocking it in *any* way, just an observation..... Stay well!)
On your statement of Vitamin D deficiency, you have missed out the major variable. Namely at which latitude you are living. 82.1% of black people are not Vitamin D deficient. It's 82.1% living at high latitudes.
You have also missed out people from the Sub Continent as their origin.
@Indigo Rodent they're not keeping it a secret, lol, Jesus
@@rogerstarkey5390 Placebo is of course always a possibility, but I also like doing research on such things. I general it's been known that people do get depressed in the winter when there's less sun, less vitamin D production and what not. My own depressive cycles felt random and happened at any time of the year. I suspect if I had tracked my diet, I'd probably see a link to improvement of mood to periods when I drank more milk. Though since mental moods have lag times (Something I learned when trying a number of different anti-depressants) I doubt I would have ever been able to link it to the milk. Same lag time of 1-2 weeks applied to when I was taking Vitamin D supplements.
At any rate I got curious and looked up some studies/research on it and there seems to be pretty strong links to improved mood and Vitamin D. In one case a comparison of a group that took 600UI against one that took 4000UI for a year. No negative side-effects and both groups did report improved mood, the 4000UI group with greater mood improvement. Course 'mood' is heavily subjective to begin with, but I still found it unfortunate that my doctor hadn't simply told me to take vitamin D supplements to see if that would improve my mood from the start as opposed to sending me on a wild goose chase of sorts trying to find an anti-depressant that worked. (A couple of them did improve my mood, but they also completely destroyed my sleep cycle, so the befits of the improved mood was basically cancelled out by the insomnia).
Depends which vitamin D if you taking vitamin D2 can cause toxicity in long use, vitamin D3 doesn't seem to show the toxicity build up
I have taken 5000 IU for several years for my bones. At 70 they are no longer borderline osteoporous. Very happy that is also helping my immune system.
So your osteoporosis got better?
I can't for the life of me understand why our government aren't making sure peoples' vitamin D levels are optimised. There is such an obsession with big pharma in the UK and US, that anything cheap gets largely ignored.
Well said! That is a 'Follow the Money" story!
Ohh yea? Who makes those vitamin D tablets and,or liquids?.. Big pharma. Who started the vitamin trend decades ago? How do you know your daily intake of vitamins, with food, sun, drinks and supplements? Maybe you're overdosing? How would you know? Seeing a doctor that will prescribe you something made by pig farm-a.
My aunt & sister, both in Scotland get vitamin D on prescription.
In the US, in the Northeast, vitamin D levels are checked with regular bloods - done at annual physicals.
You can also go to a blood draw clinic (if you need blood tests, your dr writes a prescription & you go to a lab-owned clinic to have the blood drawn by a phlebotomist & sent to their lab) & pay for certain tests without a prescription. Vitamin D testing is one example.

Paramedic here, been working the front lines, taking tons of flights during COVID and testing people for COVID-19. Havent gotten sick, there was a moment for about 2 days I felt like my chest might be getting heavy. Since the begining ive been taking Vit D like... a massive amount at least 10,000 UI a day in the start - then now every other day or so, along with Calcium, Vit C, and Echanacea. Also, on this topic I do have caramilk skin and a mix of Austrian and Jamaican heritage - meaning that also my skin color in some way plays a role in my vit D levels. So far I havent gotten noticeably sick other than the chest tightness, ive been on the front lines since day one, quaruntined a few sick people. So I would recommend w.e. it is that Vit D c/ Calcium and Vit C does. Im not recommending it as a treatment as a paramedic, im recommending it as a friend of humans, seems to have worked well for me. ALSO, I am Type O blood and apparently there is some data stating that we do see reduced symptoms in that blood type as well. Food for thought. Stay safe and PLEASE call when you need us, Where ever, When ever - Well be there for you.
do you take vitamin k2? thank you for sharing your experience!
Thanks Dr. John from Oklahoma! I have been taking Vitamin D 5,000 IU for many years per my Immunologist. Have blood test every 6 months! Enjoy your informative videos!🌞💕
My wonderful physician is especially vigilant with her patients' vitamin levels, therefore, I was instructed to supplement both D and B12 some years ago. In these troubled times I am fortunate to have received such excellent care.
God Almighty Is Supreme!
We Are His Own Children!
Amen!

B12 It's very important and should be taken in the methylcobalamin form. Especially imp for vegetarians. www.bespokebiotics.co.uk/products/super-absorbable-vitamin-b12-methylcobalamin-1000mcg-120-capsules-bespokebiotics?_pos=1&_sid=b701cd010&_ss=r
You are 1 of the few lucky 1s...most docs just do NOT care. 😢
Your videos are incredibly informative. I look forward to the updates! Thank you for providing all of this information to the public. In times like this, the need for accurate information is ever apparent. I’m a recent nursing grad looking to join the front line hoping to hear back from some hospitals soon! Thank you and take care!
Maybe explains the reason why the many many homeless living in the streets here in
Southern California haven't come down with this in the numbers anticipated. Thank you Dr. John for all you have done for so many. Forever grateful.
They live outside where transmission of the virus is almost zero. LA county health workers moved some homeless indoors. They got the virus. The people on the street did not. Health officials moved the others outside, where they came from.

People in the modern world do not live an outdoors lifestyle. It is one of the primary drivers of modern health problems.
Lack of vitamin d, fresh air and physical activity is driving cases of illness. And then on top of that people have horrible diets that are really restrictive.
People need to be eating meat, fish, many vegetables, fruits, nuts, tea, coffee, water and herbs. The modern diet of eating very similar foods over and over and over and over 7 times a day is causing problems.
I live in Moscow. After my tour to Thailand, I noticed a significant improvement in my health because there is a lot of sun and vitamin D. Then I started taking 5000 IU a day to keep my D around 60. It is improving my mood. I rarely get the flu now.
How long have you been on the dose of 5000 IU?
Why you need so much? How often are your levels measured, and how long have you been taking that much?
Good to know. Even living in Florida my D level was low and my doctor prescribed a supplement. Later a surgeon who’s got an alternative medicine inclination recommended 20,000 IU. I had a friend who believed that too much D had given her chest pain. Nevertheless I took 10,000 for a few years. Now I’m taking 5,000. Neither doctor has complained so I guess I’m doing okay. 😎
@@NeuronalAxon 5000 isn't that high.
Unless you are taking many tens of thousands each day, there should be no issue.
At high doses, taking it with K2 will eliminate any possible adverse affects, such as hypercalcemia.
Previet Andrei. "I rarely get the flu now," implying that it's a regular occurrence. Wow that made me sit up as I've had it twice in my 66 years. I've been taking Vit D 2000 IU daily recently to boost my immunity.
I would just like to thank you John, I’ve been taking 2000 IU’s of vitamin D3 and 100mcg of vitamin K2 for the last 3 weeks after watching your channel. My hay fever has disappeared and a big patch of Eczema on my elbow is healing, it all makes sense because I work night shifts and my skin has cleared up before on holiday in a sunnier climate. No more harmful steroid sprays and creams.
Been taking 10,000 for over 7 years. Had my levels checked I was only 56. If you have a lot of stress, you burn through it faster. Always take the D3 with your K2!!!
God Bless!Amen!
is it necessary to take k2 with vitamin d3? if so, why?
Thank you!
cat blue k2 facilitates absorption of d3, and you can find k2 + d3 all in one drops.

Doctor, thanks to you I began taking Vitamin D supplements months ago when I first heard you talk about that huge meta-analysis study. It seemed to me that if I'm deficient I need to supplement whether or not it will protect me from COVID-19. I'm sick that medical professionals in leadership positions around the world didn't make recommendations for supplementation months ago and I wonder how many people could have been saved. Thanks to you from me and my family.
Agree 110 percent! So many lives could have been saved and still aren't being saved because public Health officials won't talk about vitamin D3, even though it has long been known that it's a crucial Factor in immunity and overall health. I can only conclude that their goal is to enrich Big Pharma and enjoy dictatorial control over our lives rather than saving our lives.
There is no money in it as anyone can make it without a patent so the drugs prescribed are the more expensive ones.
I see they are FINALLY doing studies, I saw it on news last night. I'm PROUD of you for this one! I'm telling everyone that's BLACK, and sharing it with Doctors too.
Don't forget tell them about Vitamin K2!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Without Vitamin K, taking Vitamin D can cause Hypercalcemia Or HIGH CALCIUM IN THE BLOOD. PLEASE READ THIS.
@@illyillyill The upper tolerable limit, defined as the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects to almost all individuals in the general population, for vitamin D3 is 1000 IU/d in infants ages 0-6 months, 1500 IU/d in infants ages 6-12 months; 2500 IU/d in children ages 1-5 years; 3000 IU/d in children ages 4-8 years, and 4000 IU/d in adolescents and adults (97, 99).

@Rohit Banerjee Seriously? With an attitude like that, good luck finding someone! Even people like me living in the UK, who are almost pale blue in the winter, need d3 top ups. All anyone needs to do is get as much sunshine as they can in the summer and take a supplement, which is cheap. I still can't quite believe you actually think that!

@Bretton Woods That Works Any Time?
Thank you Dr. Campbell from Brooklyn. My pcp, 6yrs ago noticed I was low in Vitamin D and prescribed a Vitamin D regimen for me. He also advised that people exactly what you stated,people of African descent tend to suffer from low vitamin D. Hopefully NY's medical professionals and officials will realize this as a possible valid reason for disparity in COVID-19 infections and death rates.
theonlylionesse Finally I saw them talking about the link between lack of vitamin D and ppl of color on CNN last night!

@@allangibson8494 God Bless Everybody!Amen!
@@NurseViv Thank you,Viv. And this has been known for yrs. There are limited sources to get Vitamin D one of the easiest and cost free is from the sun but if you're on lockdown or have an occupation where you're primarily indoors and your shift ends when the sun is set you have less options. Salmon is high in Vitamin D,egg yolks have it and some yogurts. We have to keep ourselves informed especially since the narrative on how this virus begun and whom's more susceptible keeps changing.Take care. If you're a mom Happy Mother's Day to you.

Half way through the video I've doubled my dose. Thank you very much for such helpful information, and greetings from Canada.
Saw the first news article in the US today! Glad I’ve been taking vit D for months thanks to your advice ❤️
Hogwash, 4k IU isn't harming anyone. Takes forever for 2k IU of vitamin D to raise serum levels- months and months for many people. I maintain 50 ng/ml at 5k IU a day, took me months at 10k IU a day to get there- tablets are 3-4 cents a piece on Amazon. Vitamin D toxicity takes many 100,000s of IUs for extended periods. In the US you can walk in and get vitamin D levels checked for $60, no appointment needed.
@Bill Whittaker Name one medication or compromising health condition that would cause someone to be harmed from taking 5k-10k IU a day. *Expert Mode:* Find a single case study of any adult harmed from 5k-10k IU of Vitamin D a day.
Dr Anderson a 27 year old doctor has been giving patients and hospital staff 100,000 IUs of vitamin D and 20 to 24 grams of vitamin C by IV reports virus-infected patients are getting well in a matter of days. Dr Anderson states Vitamin C and D are the nearest thing to a 'vaccine' and can in high doses can reduce the incidence and severity of covid19.
Dr Anderson has received death threats for speaking out about Vitamin C and D as Big Pharma wants to make a killing from the trillion dollar vaccine/drug months away.... People are dying meantime.
Most doctors are either willfully ignorant or employed as consultants by big pharma which means they are effectively gagged as no one bites the hand that feeds them.
IT'S ALL ABOUT MONEY.
In any case we waited for no one and used our initiative. We daily take 20000 i.u. of Vitamin D
and 2000 mg of vitamin C timed release plus a multivitamin to supply co-factors like vitamin k and magnesium and zinc, etc.
You need to take decisive action to protect yourself and your loved one and don't trust big pharma and corrupt authority figures.

Thank you once again from Saint Helena CA. USA. Am 78 yrs and have chronic Lyme Disease. Am taking 5000 I either K2.
Would love an update on your treatment of Lyme via your moderate dose of Vitamin D.
I am a fellow RN in USA and I live in the NW northern hemisphere. I’ve been taking vitamin D year round but I titrate the dose up in October-November and titrate back down in March-April. The doses I use are 2-3000 IU, then up to a max of 5000 IU in dead of winter. I’ve had serum vitamin D levels measured at my peak dose and surprisingly it was in the recommended range but not even close to the highest level allowed. So I could even take more and still not be too much at least for my body chemistry and the climate of the extreme northern hemisphere.
I have definitely noted better resistance to catching colds and flu. So far I haven’t contracted CoV19 but I live in a more rural part of my community with fewer cases for now. Despite this I’ve been masking in public now since January when I saw leaked utube videos from China. My expertise is in critical care, cardiology and cardiopulmonary rehab nurse specialist for 33 years I just could tell how very dangerous virus was.
I myself have weak lungs. From a very young age I had croup every time I got a cold or flu. I’ve had 6 bouts of pneumonia that resulted in a gas enhanced pulmonary function testing that showed I have a diffusion abnormalities that impair gas exchange. Not taking any chances.
Thanks John, for your relentless efforts to inform us all and to sensibilize our awareness in a calm and trustful manner. I am residing in the wider region of Munich in Germany and have been watching your constant coverage of the current pandemic with growing interest. I find it alarming how little attention is paid to the general vitamin-D deficiency in Germany. For most people I have talked to, even to a few GP's and medicine students, vitamin D seems to be only associated with the metabolism of calcium and stronger bones in the human body. General health insurances do not come up for the costs of testing the vitamin-D3 level in the blood serum (which is roughly 25 EUR). One more reason why most GP's here will not prescribe this test. I myself I urged my GP for such a test in February of the year and found out that I had a severe deficiency (under 10 mcg/L !) of this hormone precursor. And I started taking vitamin-D3 (combined with vitamin K2) in form of droplets on my own. At the beginning during three weeks 60 mcg, afterwards 40 mcg daily. Some 8 weeks later I asked for a second blood test (again at my own expense), the result was 33 mcg/L. Since then the recurring infection of my upper respiratory tract has almost disappeared and my overall well-being has considerably improved. With such simple means!
By the way, correct me if I got it wrong: I think BMJ should not be confused with The British Medical Journal.
BMJ is the British Medical Journal
I want to alert people that it's not only darker-skinned persons who need to get their levels checked. I'm a pale white female living in the Southern U.S., so you'd think I wouldn't have a problem. However, about 5 years ago I asked my doctor about it because I'd been reading about new findings linking vitamin D levels to a variety of ailments. I was surprised to learn my blood level was only 12! She put me on 5,000 iu for a month or so, then I dropped back to 2,000 iu daily. Well, I have not had a single cold or bout of the flu in those five years. I firmly believe the vitamin D has helped, and have urged my friends to take it.
About 1 billion people worldwide have low vitamin D levels < 20µg/l. The lowest vitamin D levels are found in very old people, e.g. in care homes, This has tremendous effects on our body, because vitamin D is essential for all cells and a balanced immune system
Thoroughly Caffeinated , not being funny, but if you live in the south and are pale, are you just not going outside enough?
Meanwhile they are closing beaches and telling people to stay indoors.
Peak Clown-Yuga.
Fanfeck some people burn easily. In Texas, we have 100 degree weather numerous summer days.
Thoroughly Caffeinated did you have symptoms of low vitamin D? If so, can you share w us.
Thank you so much! I asked you about this recently and I appreciate that you made this video for us all. ✌🏻
You're ao pretty 😊
As a black man,thank you sir,i will spread the word,just picked up my 250mcg of vitamin D-3..thank u..
Try a stronger Vitamin D3 4000 Ui
@@thereds1959 The 250mcg that Mr Bezo "just picked up" would = 10000 IU, i.e. 2.5 x 4000 IU that you suggest.
As always the RDA is woefully low in relation to actual biochemistry requirements I personally will take between 5000-10000iu daily in the winter and drop down to 2000 is in the summer .The orthomolecular instant has carried out studies on dosage cause and effect and found that blood concentrations of between 40-60ngml to be the levels to protect against ARDS (acute respiratory distress syndrome) which is the main issue with COVID-19 in terms cytokine modulation.They are recommending taking 10,000iu daily for a few weeks and then dropping back down to 5000iu this to help bring the protective levels up to 40-60ngml.This is particularly important this time of year and during lockdown as there is very little if any UVA and UVB sunlight in the northern hemisphere.Also the orthomolecular institute carried toxicity studies and demonstrated that even taking 20000-30000iu for a month had no negative repercussions.
If you think about how much VIT D is produced by being in the sun ie 20000iu approximately for 30 minutes then it makes sense to me that this is an essential part of our evolutionary biochemistry so I quite happy to take a minimum of 5000iu-10000iu because of the 400 other biological processes VIT D carries out after all it is a hormone ..Thank you Doctor for bringing the information to the public domain I just wish the government would listen to your balanced perspective and help people to help themselves..👍🙏🏼🙏🏼
I can just imagine us all sitting here looking at the labels on our Vit D :)
Haha! So accurate
I remember the numbers myself. Of course I can't find my glasses, so I can't read the numbers. If I see them, I remember the numbers though. I just need to find my glasses......
Hehe, busted. Because someone mentioned he was taking 5000 a day, so why would my GP prevent me from taking more than 40 a day?
I likely set a record on low levels. I had to get my bloodworks re-done because the machine couldn't sense any and that had to be wrong. Driving from parking to parking, no sun whatsoever that year (weather), and dark for any errands. Living on potato crisps probably didn't help either :D
I can't remember the units, but I was at 0.5 something, while the initial "machine" (?) had a lower bound of 5. The absolute minimum recommended was 25, but 50 preferred. My GP said I would be better off at 75-100 and put me on an intensive supplements. Next bloodworks showed adequate levels, but I can't remember numbers. I have been at 80 every second day, but I've just upped it to 80 a day due to current events (highest tablet dose available here), along with Vitamin C and zinc - which I'm likely not getting any of anyway. Now the lid of the Vitamin D supplement reads both 80ug and (3200 IE) - should avoid confusion. But despite having severe lack of Vitamin D and also other things, I was very rarely that kind of sick. No flu (only twice in my 50 year adult life, but they did hit very hard - now I'm taking the shot), and barely the common cold.
I did that to make sure I'm taking enough.
I did exactly that Heather!! lol!! I take 2000-4000 a day. I have hashimotos and my FM doctor and my dietician encourage me to be in the 50-70 range.
I like how Dr. John works hard to be clear and understood.
Thank you, Dr. Campbell. Really appreciate your channel!
Thank you !!!.. keep posting Please.. I really feel .. ( I’ve been following you since very early February) that you have saved my life and those of my friends!!.. without your early warnings ... we would been a clueless as to what was coming.. and thus not prepared as we are to fight the virus... Thank you so Much!
A very important issue that is almost never mentioned in the media. Thank you John:)
And please include Sweden in your daily sessions if you find it important. That would be appreciated. Stay safe!

I have taken 10,000 units of Vitamin D through the duration of the pandemic and have had no toxic effects and have not gotten sick. I wonder how many thousands of people could have been saved by just recommending they take Vitamin D or at least get their Vitamin D levels checked?
Dr. Campbell, I am greatly appreciative of your efforts to inform and educate us. Greatly appreciative.
Hi Dr Campbell, late viewing today, this is my cleaning the house day! Thank you for all your Vit advice! I have taken all your advice and did my own research as well, and I have been running around with all this energy! But I eat well too, so that helps!
I think you have helped many people through this time of darkness, we all 🙏🏼 you !
Stay well and be safe! 😇🙏🏼😘♥️ Suzy from Cleveland Ohio 😍
My doctors have always told me I had low vitamin D, ever since watching you I’ve started taking supplements for vitamin D. It’s good information to know for sure! Rather be safe then sorry. Thank you Dr!

@@stephen3654 Don't be so mean, Clive. There are some doctors who never mention taking vitamins. We need to get important and truthful information wherever we can these days.
@@goldkhw True so true
Excellent Report yet again Dr John! Thank you!
I'm diabetic and after my blood test in January my doctor recommended I take vitamin d3. So I've been taking 4000iu daily for 10 months now. Since watching your videos I've recommended to everyone to take vitamin d3.
The old toxicity levels are based on vitamin D2 research back in the 30s and is highly obsolete. People can take up to 30,000 iu per day before there is any danger of toxicity however it is better to get it through the sun where possible. You can also increase it through fasting which will also boost your immune system and reduce blood sugar and blood pressure very quickly.
Some of the myriad benefits of fasting on the immune system, blood pressure, blood sugar and anti-aging, all evidence based:
Vitamin D plasma levels are increased.
Blood clotting is reduced and blood clots and arterial plague are absorbed into the body.
Blood pressure is dramatically lowered very quickly when you fast which is very important for a good outcome with the current pandemic.
Blood sugar and insulin are lowered, allowing white blood cells to move more freely throughout the body and do their job. Ideal blood sugar is around 80. Some viruses activate glycolosis (the release of sugar in the body) and clinically it has been shown that decreasing glucose metabolism in the body weakens the influenza virus.
The hormone Leptin is a cytokine and Leptin resistance and high leptin levels impair the ability of the body to regulate the immune system. Fasting very quickly reduces leptin resistance and leptin levels and one day of fasting can cut your leptin levels in half!
When you move out of MTOR your body shuts down the building blocks of the cell which are used to produce organelles and proteins. This means the mechanisms needed by viruses to replicate are by and large unavailable when you are in a deeply fasted state.
It stimulates the AMPK complex and activates autophagy. Autophagy (literally self eating) will cause cells to recycle foreign matter such as viruses. AMPK does many helpful things in the body including activating the body's antioxidant defenses.
Deep ketosis virtually eliminates inflammation in the body. This can offset the life threatening symptoms of viral pneumonia which effectively kills you through inflammation. This also creates BHB ketones in your body, which also help your immune system and anti-oxidative system, especially in the brain. Ketones also provide an additional energy source during infection, which is critical when trying to fight off a bug. In fact you can have as much as three times the total energy available in your blood when you are in deep ketosis, or even more.
It increases mitochondrial function and repairs mitichondrial DNA, leading to improved ATP production and oxygen efficiency and thereby making cells better able to fight off infection. Increased mitochondrial function also has the added benefit of increasing your metabolism and cancer prevention!
T and B immune cells retreat to the bone marrow and are renewed at a genetic level, each cell having all its DNA repaired. This supercharges your immune system and makes your cells young again. On top of all this, fasting encourages the direct apoptosis (death) of infected cells, shortcutting the typically length and messy process of killing them off through macrophages which can kill off bystander cells and is part of how cytokine storms cause issues..
Your body releases interferon which is also triggered by the body during viral attacks to shut down the replication ability of the surrounding cells and stop infections.
After 72 hours or more fasted, your body actually recycles large numbers of immune bodies and creates new ones, rejuvenating your entire system. In this process many white blood cells and mitochondria fuse together and the working parts of damaged cells are kept while the bad ones are recycled. Stem cells also release into the bloodstream at this point.
When you fast, this stimulates apoptosis in senescent or genetically damaged cells. This kills these cells off completely. Senescent cells are responsible for the effects of aging and are the root cause of the development of cancer. If it were possible to destroy them all it would completely stop aging and cancer. That is not possible but fasting can help limit these effects by killing off many of the affected cells and limiting the future effects of aging.
Fasting also releases BDNF and NGF in the blood which stimulates new nerve and brain cell growth, helping a great deal with diseases like MS, peripheral neuropathy and Alzheimers.
Eating one meal a day can bring most of these benefits to a lesser degree, and adding a few entire days off from eating per week will have even more effect especially when starting to feel poorly.
Pregnant or nursing women should not fast, nor should people with pancreatic tumors or hypoglycemia. Type 1 diabetics can also fast but it is more complicated and should be approached with caution. People with Addison's disease may also be unable to fast. If you experience extreme symptoms of some kind simply break the fast and seek advice.
Thanks for this, what is your source? Whenever I advocate the health benefits of fasting - nobody believes me!
Excellent ..will start 7 day fast on Monday and intend to do Ketone diet as carbs make me bloated and sluggish ...great information!
So taking a 5000 IU vitamin D tablet a day is safe?
@Joolzratbag Many people don't want to believe because if they believe then they might have to actually do something about their situation and they wrongly think fasting will be extremely hard, but it is very easy so long as you slowly work into it. Everything posted is directly from one of these studies and there is much more info as well.

@Dr. John Campbell Thank-you for all you do
Thank you Dr.Campbell, my question have already been answered by your video. We all stopped taking Vit D when summer is already here in the Phils bec it is way too sunny, everyday we are under the sun.
Many thanks for your teaching style and details that I found very informative and hopefully will reach to large audience. I live in Saudi Arabia where it is sunny almost 360 days a year but still many people suffer from vitamin deficiency, maybe due to the fact that we avoid direct sun exposure to avoid its heat. I wish there is a home kit to measure Vitamin D similar to sugar measuring kit.
Thanks again Dr. Campbell.
The covid treatment protocols that are evolving, do seem to utilising Vitamin D. Also Zinc and Vitamin C.
EVMS protocols are recommending Vit D, Zinc, Selenium and Melatonin
Thank you. Appears you're ahead of the curve on what works against Covid. Clif High also recommends Chaga which is easy to get at PureBulk.

Hello, Dr John. Great to see all the literature on Vitamin D. Thanks for your hard work.
In 2003 I was taking over 3000 IU; in 2014 bumped it up to 5000 IU; in 2018 raised it to 10,000 IU per day.
Got the results of my test today. Looks good according to the video. I've been taking 1000 IU daily for the last few years but stepped it up to 2000 IU in September. Thank you for your excellent videos Dr. Campbell!

Somehow I missed this video, I thought I had seen them all. The US recommendation is still only 600 IU, I’m taking 5,000 now. I suspect I was very deficient for decades because I was mostly on bedrest, or at least hardly left the house. Thanks for bringing the importance of this Vitamin to my attention.

Thank you very much Dr Campbell for a very informative video. In the absence of testing for Vitamin D at the moment, I think 2000iu is a fantastic daily dose.
you are amazing in explaining such a difficult subject. Thank you
Thank you for the wonderful information Dr John.
Been taking 5000iu D3 combined with 100 mcg of K2 for the last 5 years in UK. Had blood tests done last November and Vitamin D levels were 160 nmol/l Should always take K2 with D3 because it mobilizes the calcium in the blood to where you want it - in the bones, and not where you don't - as arterial deposits.
Did your doctor say your D levels were too high at 160?
@@1xstew lol I am no doctor, but that is way too high. This is the kind of batshit response that comes from unqualified people on CZcams diagnosing and prescribing entire races and populations of people based on horse shit studies with marginal if any relation to the current situation. I cringe more and more every day I hear this stupid shit.
Spot on about the K2 because D3 increases absorption of dietary calcium. K2 activates protiens that (a) hoover up calcium wherever it may have deposited itself, and (b) direct the calcium into the bone matrix where it should be.
@@1xstew In the UK my doctor said the acceptable levels are 75 to 200 nmol/l, so they are not too high
Absolutely correct. K 2 is very important to take with Vitamin D 3. Excellent point.

Stay safe Love Bella
Bella Brooks See vitaminDwiki for more info.
I get definite unpleasant side effects if I take more than 4000IU of vitamin D (liquid capsules) and I think people should be careful not to take too much. For me, 2000IU each morning seems about the right level.
Thank you so much for sharing this information. My sis has an autoimmune and has to take chemo regularly for the rest of her life so she is now planning to ask her specialist to look into this for her.
I fully accept that age per se is a strong factor, but older people with reduced mobility don't go out much either. VitD3 is such a simple thing to do with so many benefits apart from Covid19.
I always feel better if I can do something simple, sensible, & positive to help myself.
Several Studies show, that in some countries about 90% of elder persons, who are living at home, do not take vitamin D supplements, and their skin cannot produce enough vitamin D
You don't accept it, you HAVE to accept it because it's a fact, period no debate.
I had a suspicion that I might have low Vit D but my Dr.refused to test for it because it was to expensive (I live in Canada) I decided to supplement anyway and my mood is better as well as the nerve pain that I have had constantly for the last 5 years has greatly improved.
Betty Vorley yup bit D test cost is obscene here in Ontario Canada.
Yes, that is always good to do. Surely your doctor has a grand scheme to be vitamin D deficient. Have you thought about the possibility that you just don't know wtf you're talking about? Whereas your doctor that went to school to learn about all this shit for 8+ years might know a little something?
I asked my husbandʻs doctor about a vit D test and he said he usually does not do them because Medicare wonʻt approve it since it is so expensive. So it is not only in Canada but here in the US as well. He prescribed 5000 IU vit D for one month because he had also been reading about it with regards to covid 19
Betty Vorley
In the Netherlands you can order a vit D test kit for €29. All in
Doctor friend of mine who practices in Alaska treats many suffering with SAD. Light boxes are so expensive. He found a small “plant light” from Wal mart etc each morning with coffee or tea just as effective. So started doing it 10 years ago, and now have 10 beautiful plants that have joined me for coffee over the years.
This was awesome to listen to! thank you Dr Campbell!
Thank you Dr. Campbell for informing us on the importance of Vitamin D levels. May I ask you, do you take Vitamin D all year round or just Winter-time? I live in Ireland (not a lot of sun lol) !

Two months ago Dr. Campbell quoted a BMJ article from 2017 about VitD deficiency. already.
They will look into it and come up with a wish washy recommendation like improve your diet and it 'may' help to take vit d at 200 i.u or more research is needed or some crap like that...
it is mostly staffed by drug company reps.
God bless you for your information..Am Somalian and I been telling my community to take vitamin D for a month now..I was sunbathing in the park almost everyday in my local park here in London..I was told of by police to move on or be locked up and I refused.I told them to lock me up because am not moving on mate..they let me be..

i take 5000iu D3 every other day, with K2 (MK7) and magnesium
Ginger&Garlic Sounds Good. See vitaminDwiki for more info
@thecomfortstation K2 Mk7 is to direct the extra calcium absorption out of the blood and into the bones.
@thecomfortstation Magnesium helps keep calcium from being leached out of the bones by the Vitamin D.
It is easy to get potassium(k) from foods such as green vegetables and citrus fruit. Vit D is difficult from foodstuffs that is why a supplement is needed for it often.
I’m curious about the K2 portion of it, I was reading K2 aids in clotting, but isn’t one of the issues with COVID19 is unexplained random clotting? So would K2 increase the risk of complications?
thank you sir, for your voice and dignified delivery, along with the quality of your information.
Been taking 10,000 for over 7 years. Had my levels checked I was only 56. If you have a lot of stress, you burn through it faster. Always take the D3 with your K2!!!

There is a link between Mental health and Vitamin D levels my sons CPN pointed it out when I pointed out Dr Campbells data.
I was advised to take a Codliver oil capsule a day to cope with my anxiety while my wife was terminally ill.....have been doing it ever since, and noticed a certain feeling of mild anxiety one time when I ran out..I am 73........I would agree with you
Agreed. 💯
Seasonal depression disorder is induced by lack of sun, and treatment includes taking vitamin d. So there’s definitely a mental health impact of low vitamin d.
Low vitamin D causes testosterone production to be suppressed. Low testosterone in males suppresses dopamine production and low dopamine leads to generalised lethargy and low mood both symptoms typically associated with depression.
The Maudsley Hospital (UK) did a study on this quite a while ago, cannot find the study at present, which led to me taking vitamin D supplements long before C19 arrived, more energy, better mood, and less colds and sniffles - no downsides why Vit D is not being tested or pushed by GPs - No idea...
Excellent video. Thank you Dr Campbell🌴
Well done Dr Campbell keep up the good work x
For those in the UK, I bought a Vitamin D test kit from a company called Cerascreen. It was less than £30.
Yes, I have done it from Switzerland. It worked great. I had a level of 29ng
....
So I raised D3 to 10 000Iu per day.
Omg...my thesis topic is related to this...glad I found this😍
bought a 50,000 IU D3 from Amazon by forest leaf. I haven't touched the stuff as I am still researching...have you come to any conclusions in your research that 50,000 IU would be bad for a human to consume
Very informative, thank you for sharing the information.
Hello Dr. John , hope you and your family are well, look foreword to every day with you and your informative vlogs for all of us, continues to be very scary out there, I believe the US is moving to fast in reopening, I hope it doesn’t result in a surge of this terrible virus. Take care and stay safe!
My levels were recently tested (struggle to maintain levels). GP has me on 4000 units a day for 6 weeks, then 2000 for maintenance. I live in Queensland Australia. We are the skin cancer capital of the world. Due to the harsh sun, there are significant numbers here that are deficient in vitamin D. Also the heat in summer keeps you indoors in air conditioning.
I was a week in Portsmouth UK and Isle of Wight this summer. I found a heavy correlation between sun exposure and body leanness between the isle and the city: it was absolutely clear that, despite having the same culture and food, people living in Portsmouth were much more prone to being heavily overweight than the islanders just a few km away.
The only real difference was that as a city you would have worked often inside while most of the island life was outside and all houses had a large garden and outdoor areas.
The difference was so stark it was impossible not to notice.
I also noticed this correlation. When I’m tan, I tend to lose weight and when I’m not so tan, I tend to gain weight.
@@Cutest1TheGame small thing: I bought D3 from H&B and then from Nutrivita. H&B was absolutely better. Despite size being the same and IU being the same, the effect on me and my wife was astonishingly different. I am unable to understand the reason but I thought it would be a good info.
Very interesting...but the islanders on Isle of Wight are probably more likely to be wealthy/not poor. Thats always a factor in nutrition studies..i do think that people can turn to fast food for comfort in despair. Organic food, as we know, cannot be afforded by all..and the islanders are more able to grow their own. 🌾🌿🌱🌻
@@anjou6497 possible, but we are still talking about few km distance. The difference is so stark it is visible to the naked eye.

Awesome! 👍👍 Here in Brazil despite its sunny weather we also suffer a lot from this deficiency.
Two winters ago I had a really bad year for SAD, so I have been taking 4000iu since then and Last fall/winter was an easier winter to get through.
Chantelle McLaren (Alyssa Chey) Same here. My son suffers from skin cancer so has to keep covered, we both started D3 two years ago. No depression tablets over winter months any more.🇬🇧
Another good natural anti-depressant is Flush-Free Niacin. Five years now, I take it occasionally in winter due to SAD.
@@stephen3654 I just know taking Flush-Free Niacin to prevent the flush (redness/rash) side effect. Flush-Free is good for depression, but not effective if you need Niacin for heart disease.
