      hmmmmm. Not sure about the study. The idea of good vitamin D level is to fight off prevent by healthy immune system....so if you are already tested positive then trying to reverse the spread and infection by using vitamin D would not have too much success rate. The better idea is to have healthy vitamin D level PRIOR to contact with a virus germ .....

    When I lived in Seattle, I worked for a time at the Phinney Neighborhood Association, which operated out of two former schools, one built in 1904 and one in 1917. One was wood and the other brick, but what they had in common were extremely large west-facing windows in their classrooms. During the afternoon, those rooms were flooded with direct sunlight. They believed in the health benefits of sunlight for children.

      Not all UV wavelengths go through windows: "Standard window glass, according to the International Ultraviolet Association, will allow UV-A to pass through while almost 100% of the UV-B and UV-C light is blocked." So we need to be careful of extrapolating between indoors and outdoors. However, the light itself absolutely must help with overall mood. My house has NO south-facing windows and very small west-facing ones and I'm in Olympia. It is the most ridiculous design! I suffer from seasonal affective disorder and the winters in this house nearly kill me with cold and depression.

      MS is another disease that correlates highly with high latitudes living (during childhood). By late teen years the risk factor for it is already baked in. But I think some sun improves everything. People who go for a short walk with long sleeves, hats and sunscreen make me laugh. I recently got plantar fasciitis and can't walk much, it''s too cold to stand still outdoors so getting little sunlight. Its killing me (mentally and maybe physically).

    As a pale but not yet feeble one, I did not know what my Vitamin D levels were, but guessed that they were not high, so started 1000 i/u per day supplementation. After 15 months I got a test which showed 26 ng/mL, which I considered inadequate. So I started sunbathing for 20 min before 9 am when sun and time permitted, and supplementation up to 5000 i/u on non sunbathing days. After 7 months of that my vit D test showed 56 ng/mL. I also have a modest suntan for the first time in 73 years! Sunbathing also seems to improve sleep, and mood. It just feels good. I have never tested positive for Covid despite having it in the house three times. None of this proves anything but I like to feel in charge of events and this regime achieves this. Thanks for the advice.

    There is no paradox. These vitamin D studies do not ever, to my knowledge, test people who have vitamin D levels above 60. 70, or even 100 ng/ml. From my experience over the last 11+ years of keeping my vitamin D level in the 100 to 130 ng/ml range, I just don't get seriously sick anymore. I am 75 years old now and in the last 11+ years I have had only two mild colds and only 1 very mild covid 19 infection. The covid infection lasted about 4 days and was very like a mild cold. Show me one test where people received 8000, 10,000 or 15,000iu of D3 daily (dose dependent on body mass) compared to people who received a dose of 4,000iu or less of D3 daily. While taking higher D3 doses you should also take vitamin K2 and magnesium.

    I’ve had a history of chronic bronchitis that lingers. I’ve also had a history of Vitamin D deficiency. A comprehensive medical exam in 2018 showed low Vitamin D and the doctor told me to take OTC Vitamin D. I did my research and started taking D3, but I wasn’t sure of the dosage. Anyway, I wasn’t really diligent and in 2019 I had a weird respiratory infection that lasted about six weeks. I recovered but when the COVID pandemic came about, I did more research and started taking 10,000 iu of D3 combined with K2. In 2022, I took a home Vitamin D test and my level was optimal at 76 ng/mL. Ironically, since 2020, I haven’t had one cold and zero respiratory issues. Also, coincidentally, I moved to a house with a very large back field in southern Nevada and walk my dogs every day. So starting in 2020, I was taking an increased dose of Vitamin D3 and getting more regular daily sunlight, not to mention taking daily Vitamin C and Zinc. Maybe it’s just a placebo effect but whatever it is, I’ll keep it up!

    The mixture of scientific rigor and open minded consideration of alternatives which you present is truly excellent. You have been meticulous in distinguishing correlation from causation, plausible mechanisms of action from demonstrated mechanisms, informed speculation from proven interventions. I appreciate your promotion of sleep, sunlight, and even things like "forest bathing" as "there is reason to believe this might help and it's very unlikely to harm" as an alternative or complement to the "distill everything into a pill" approach - but you wait for confirmation before claiming effectiveness.
    What other channel can integrate both forest bathing and AT II ---> AT 1,7 via ACE2 pathways, each in their respective place?
    During the more acute phases of the pandemic, your channel was a breath of air which helped me process what was going on. I don't follow as closely now, but the sound of your opening music still evokes a very positive feeling in me, like a memory of seeing a light in a time of darkness. It's likely the strongest musical cue I have that takes me back to the depths of the pandemic (and probably still will a decade hence if I'm around), and I'm glad that it also invokes hope that with science and rationality, balanced by lack of dogma, we humans can persevere.

I was 57, reasonable health, pre-diabetic and just over the Obese line and live coastal SoCal. I rarely get sick. I did all of this because of a study at Harvard which a family member was aware of. That study was never released... It doesn't sit well with me that the protein ratios in C-19 are round numbers (not typical in natural similar viruses). Because of the ratios and how badly our government pushed for vaccinations, has made me not trust our government related to C-19.

      If the govt. had pushed ALL known methods of resisting Covid in addition to the vaccine, such as methods to improve your own immune system, it would have been better regarded as an honest agent. But unfortunately, even before the vaccine came out, there was no mention about alternate methods that a person could do for themselves to help make their immune system sharp. Not even for minors.
      Today, if you don't want the flu, the vaccine is pushed as the ONLY solution. I remember researching the CDC flu vaccine efficacy tests for my age group and was shocked that it was less than 40% (depending on the strain). They demonstrated a huge bias toward only the pharmaceutical industry as the ONLY option to resist Covid or the Flu. I stopped getting sick when I got my Vit D and Zinc levels proper several years back Coincidence?? Not based on what others have also been reporting.
      I'm not anti vaccine, but I believe the govt. should have outlined all possible methods that people could do for themselves to help prevent Covid, even if these methods were not as good as the vaccine, AND our govt. should have leveled with us about the true efficacy of the Flu vaccine over the years as well. Our govt. should be our independent source of accurate information, not solely an extension arm of the pharmaceutical industry.

      Actually, I wanted to reply to your understandable despair with our great divide and devils dressed as saints remark by quoting a line I'd heard in the wake of 9/11 attributed to Paul Harvey ("In times like these it's good to remember there have always been times like these.") which at the time struck me as "too extreme," but the concept of context has mellowed me to it. I still don't know if/when he actually said it, but just now trying to search it, I find an amazon book "don't forget to sing in the lifeboats" which apparently also includes Bill Maher's version of the same notion : "If you think you have it tough, read history books."-Bill Maher
      In reality, just because somebody else has it worse, that doesn't make my life better . . . but it does tend to remind me of some of the AWESOME things about life I have on the daily that I'm taking for granted. It is natural for my mind to FOCUS on the things that are "wrong" in life, because, seemingly that's what needs the attention, but it is critical for the "physician, heal thy self," as they say, if you don't take adequate self care, then you won't be able to be of help to others. Being numbed to trauma may be a natural self preservation reaction and as a spiritually minded mate once told me "some days just not slipping backwards is a win."
      I've long claimed that given the choice between laughing at something and crying about it, I'd rather laugh... but increasingly I'm supposing I really need to do both. On a blue moon, when I realize my eyeballs are overdue for a good washing, I'll actually seek out a bittersweet video in youtube like the Brooklyn Duo (Piano & Cello) performing Canon in D or one of those Encroma (glasses for the color blind) where some tough all bastard who's been color blind for decades sees a sunset . . . oh, geez ... here come the water works . . . quick, somebody sing, please!

Today, most doors and windows in businesses and homes contain glass that blocks UV rays you normally get from the sun, for energy conservation. That's a problem for both you and probably your pets. For the exception of Dr. Scheult, most doctors are also NOT into preventive medicine. A doctor's role is medical treatment when you get sick. So basically we're on our own when it comes to prevention, which makes Dr. Scheult's video's so valuable to me.

      A High Carbohydrate Diet, like the Standard American Diet, will deplete the Body of Vitamin D, the B Vitamins, Vitamin A, and other nutrients necessary for proper functioning of the Immune System. It not only interferes with absorption of Vitamin D, but the resulting High Blood Sugar and Blood Insulin spikes from such a Diet result in Oxidative Stress that leads to Systemic Inflammation, taxing the Immune System and making these deficiencies worse.
      Over Decades, the Hyperinsulinemia from a High Carbohydrate Diet causes Insulin Resistance, leading to Hypertension, Fatty Liver Disease, Diabetes, Cardiovascular Disease (not surprised your Cardiologist recognized the association), Cancer, Kidney Disease, Autoimmune Diseases, and Dementia/Alzheimer’s.
      Extra Sunshine Exposure and Supplementing Vitamin D can be ineffective if the Dietary Root Cause is not addressed. A Healthy Ketogenic Whole Foods Diet combined with Intermittent Fasting is the best way to manage Blood Sugar and Insulin while obtaining the essential nutrients for optimal health. 👍

(Proven in a study by Univ of Chicago with a fiber optic light tube shining behind one knee of fully clothed and covered people - all melatonin production stopped!) Any part of the body detects any amount of light leaking into your room. Utter darkness and a cool room for optimum sleep. Hang heavy drapes. Think cave.

    Given the relatively safe profile of vitamin D, most doctors are still sleeping at the wheel. 3,200 IU is still a bit of a joke. A number of
    people I know take 5,000 IU, but most can't even reach 40ng/mL. I now take 7,000 IU to reach 50 ng/mL which appears to be the
    optimum level for your immune system. But even still, you need auxiliary supplements, zinc, melatonin, omegs 3, NAC, tumeric etc.
    And on top of that walk 30 minutes in the sun, wearing as much clothing as you can stand, to cause heavy sweating. You get
    both UVA and boosting of your interferon. And this is for free. Maybe the only way to really battle Covid, meaning not suffer
    long Covid, is to boost your immune system, which is not the same as vaccines, such as mRNA. These very specific vaccines
    leaves your body completely unprotected as the virus mutates.

    Good Morning Dr. Seheult,
    As always, I hope all is well with you and your family.
    Thank you for always communicating things so clearly. I've been listening to your reports/updates since the beginning of the Pandemic. What you have shared has been life changing and I often share what I learn to help others as we live through these very trying times.
    I'm an black male who embraced the profound evidence based conclusions regarding supplementing with higher doses of Vitamin D3. Based on the evidence being presented around the world my family increased our Vitamin D levels to 87ng/ml to 100ng/ml, at the very beginning of the Pandemic. We test our levels twice a year to ensure we main levels on the higher spectrum. I decided to put my trust in the research as billions of people do everyday with prescription medications. A, P-value of 0.001 is very significant. I decided to completely put my trust in what I concluded to be true, even down to the Indian study if we were ever exposed... outcomes proved highly beneficial within 3 days, attributed to optimum D levels as well.
    I'm an advocate for sun exposre, whoever, given our cultural realities around the world, adequate sun exposure for black people and people with darker skin tones in general is a major behavioral shift for not only the afore mentioned ethnic groups but for all groups, unless cultural norms dictate otherwise. However, in my efforts to defeat Vitamin D Deficiency globally, I have advocate for sun exposure (how ever much we may benefit as a race of people) in conjunction with optimized Vitamin D levels.
    I do have a few questions. Is the absorption and use of infrared radiation inhibited by darker skin as with UVB rays? If so, how much longer should people of color be exposed to sunlight in order to reap optimum benefit (mitochondria, melatonin, circadian)? Last question, If melatonin proves to be a blocker without prolonged sun exposure, does that mean, darker skinned people are limited once again due to the pigmentation of our skin color or should we drive and conduct additional trials on treating COVID-19 with doses similar to that in the Indian study, until we have a better treatment course? I ask this because black and brown people of all shades are still the highest risk groups of dying from COVID-19 because our Vitamin D levels are so very low?
    Lastly, what possible role does Vitamin D play in controlling ADE occurrence within monocytes causes massive inflammation all over the body?
    As always, THANK YOU FOR EVERYTHING! Me along with millions of others truly appreciate every second you give towards informing us on what we need to do to get healthy and maintain our health.

    It’s not a paradox.
    If you’re about to jump off a bridge actually having the bungee cord attached before you jump is much better than someone throwing it to you as you fall.
    Having high serum levels of vitamin D before infection is very protective.
    Treatment with very high doses of the bio effective form of vitamin D has been trialed and has shown some benefit but usually it’s too little too late.
    It takes time for the body to build up serum levels especially when some infections actively block the vitamin D receptors.
    There is a danger that the impression that taking supplements won’t help there for don’t bother will be the message people get from reports about ineffectiveness.
    The message should have been screamed from the rooftops to take vitamin D.

    Nice video, well done. I didn't realize we use near infrared light as well. Do you (or can you) recommend an medical indoor light that will cover the safe spectrum of light that we need? Do they even exist?

    I have been taking vitamin d for many years as my level was at 9ng 5 years ago. I have been supplementing with an average of 5000ui since then and latest blood test showed my level now at 34ng a year ago. I have multivitamins along with extra d3 for my 3 kids. my 16 year old tested positive for covid in January and he then admitted to me he hadnt taken his vitamins. Out of 5 of us in the house, he was the only one who tested positive and was sick. The rest of us take vitamins including d3 and kept testing negative and never had any symptoms. I'm not saying its the Vitamins...but it really is too much of a coincidence not to believe personally.

      I've had similar luck, dodging symptomatic infection when others did not. Vitamin D likely prevents nothing -- it merely equips our immune system to do its job, minimizing infection severity. It's like water to a fireman.

      It’s simple. Severe Covid causes Vitamin D deficiency. Severe Vitamin D deficiency causes other problems. Replacing the Vitamin D solves those other problems, but doesn’t effects Covid itself. But solving those other problems can reduce your risk of death by those other issues that are caused by severe lack of Vitamin D. However, Covid can still kill you, and cause other severe issues.

    My faith in scientists is restored when I listen to arguments such as yours. Science communicators, on the other hand, shame us for not accepting the obviously flawed conclusions some studies reach. They don't even understand the results and want brownie points for just associating themselves with science.

    Thumbs up! I still wish you would understand how vitamin D goes through the body. The goal is not to get 25(OH)D3 levels up. The goal is to get 1,25(OH)2D3 to the VDRs to effect gene expression. The 25 form is the WORST form for this due to being tightly bound to VDBP. D3 itself enters cells where the 2 conversions take place allowing the 1,25 form to make it to the VDRs but D3 has a half-life of around 24 hours. The "paradox" disappears when you understand this.

    Fascinating! I have read many things over the years that seemed to indicate health benefits from being out in the sun, yet all of the emphasis was on the danger of UVB exposure. This could be the explanation! Avoid UVB, but get lots of NIR! The anti-oxidative effect of melatonin also raises questions about melatonin supplementation. Thanks! I’m going outside now.

    Yes! this has been my experience too. I supplemented with 5K IU for over a year and although that helped and my level came up to 55, I still had a hard time with covid until I have saw your video on light as medicine. I started spending hours in the sun and daily sauna use and was able to finally recover from covid.

    It’s a simple one to solve- when trying to invoke a rapid response, it takes a much higher initial dosing. First, it takes a bit of time to ramp-up melatonin and related levels and also at least 6000 IU upon acute onset to make a difference, which is substantially higher than many using/testing Vit-D in response rather prophylactically. Some use 10,000 IU for the first and second day, and then start trailing down to about 4,000 IU. There is a reason why hospitals often use a one-time massive 50,000 IU dose upon admittance (for entire week), and why 2,400 - 3,200 IU upon acute onset see little benefit. Also, that BJD is NOT independent of the Vitamin D pathway, since creation of Vit-D from sun is NOT an on/off switch. When you positively correlate it with sunlight exposure- even at slightly higher latitudes, you are STILL correlated with Vitamin-D exposure, as noted in that report.
