Another great review Gil. You are a wonderful source to keep us balanced with the ton of studies and wild information out there. Hoping all is well with the family and hope to see your content for a very long time. All the best.
Thank you, finally someone with no hype, who I can trust. Science background here, and I take the science very seriously. Your videos are very informative, thanks for delving into the research and doing excellent summaries. Saves the rest of us a lot of time!
Gil, I am quite suspicious of the reduce-it trial because it was not a true placebo control RCT since the "placebo" was mineral oil which is known to be pro-inflammatory and is likely harmful.
I was experiencing A Fib after taking Fish Oil tables . I stopped taking it and the A Fib went away . After a few months I tried taking Fish Oil tablets again and the A Fib came back .I was taking 1g . I now get my Omega 3 from my diet and have had no issues /no A Fib.
Me too ! It was awful so I just use ground flax and no afib. I took it for years with no problems… I think it could be chemicals to process fish oil … I am healthy, fit, thin, with no health problems but fish oil now gives me afib. I tried many times with same result .. so flax it is 🎉
Very good video that was clear and well nuanced, ending with good answers to what an individual might do, given what we know and how well we know it. Thanks, Gil, for all you do. Would you consider a video specifically about your diet (and any supplements) - What do you eat/take and why? I think given your knowledge and background, a talk about your choices would be helpful!
I always find that if I listen to your videos all the way through, the questions that start popping up in my head get answered. Thanks for covering algae oil.
Would be cool to know is this about DHA/EPA or fish oil itself, how does it compare to algae-based oils. And what about ALA? There is so little info about ALA, compared to DHA/EPA.
Interesting. I was facing with some afib symphoms and suplementing 500EPA 750DHA every day. Since begining of spring cut it to one dose 250/500 and any symphtomps just stopped. It wasnt because I heard about side effects of O3 - just decided to lower my dose. Now it's second month since I dont suplement it anymore, but from time to time I consume some tasty fish. None of afib sympthoms anymore to this day.
I'd be interested whether vegans who eat lots of ALA omega-3 benefit from an algae supplement. I take them currently but I don't really know how much good they're doing me.
I've tried many brands, but whenever I take omega-3 I feel weird and sick, I reduced my supplementation to a single capsule only twice a week, to avoid any noticeable side effects.
I'm 63 and eat a healthy diet and exercise 5 days a week. I eat salmon and tuna every week and take fish oil supplement every day. I brought my cholesterol down from 220 to 130. Works for me.
Why do you contribute that result to consuming fish oil and fish? It can have nothing to do with it. Excercise and diet alone can achieve such score. My total cholesterol is 80 and I don't supplement fish oil nor eat fish. Such claims don't mean anything. Just pointing out.
Another nuanced and informative video, thank you sir! I do wonder whether or not fish oils are still worth taking in general due to the supposed health benefits for the brain?
I started taking fish oil because I read an article saying it can reduce rage. Idk if it's the pre-menopause, but I get this rage from the depths of hell!!! Hasn't been a month yet, but it seems to be helping so far. Can you speak on this please?
Another thing that goes back and forth. One day you must take it (up to 4,000 IU a day) and the next day it's no good for you. I take a plant based EPA/DHA because I am allergic to seafood. I live in a place that only has 3 months of summer sun, so I take 3,000 IU a day. Now, should I be lowering that to 500? Who and what are you supposed to believe anymore?
True. But the thing is no one really can tell you that. At least with 100% confidence. Including your doctors and Gil even more as he doesn't know your medical and family history. Intermittent intake sounds good to me but I'm just a random layperson. Edit: How could I miss you were using IU instead of mg... 😅
Yup. Seems like a fool's errand to try and optimize diet to this degree when dietitians can easily flip-flop on what they were so confidently advocating for just yesterday.
Gil, what about flaxseed oil as a source of omega 3s? Since developing consistent PVCs over the winter, I cleaned up my diet and started taking 1-2 tablespoons of flaxseed oil daily. Any studies done on that? Keep up the excellent content!
When it comes to getting your intake of omega 3's from whole foods you can cluster it into 2 days of the week. Can you do the same thing with omega 3 supplements? ie: take a two big doses in the week instead of every day?
I believe those larger studies showed aFib risk from omega 3 intake varied by vagal tone. Low vagal tone had few aFib issues, high vagal tone (low resting HR ect) saw most of the increased risk with omega 3 supplementation.
Thank you for acknowledging algae supplementation. I don't know why these studies don't compare those to the fish oil. What if the algae oil doesn't have any side effects. It would be so cool if they could also compare those who consume a well-planned whole Food vegan diet with a regularly high intake of alpha linolenic acid rich foods like nuts and seeds. Feels like nothing's really changed still after some long. Great video, Nice update!
Question regarding healthy fats. I am 23M, healthy. I've been consuming 25g of Olive Oil, 25g of canola oil and 33g of ground Flaxseed every morning for several months. Had my bloodwork done in connection with some medication and Triglyceride was 7.87mmol/L. Doc told me to stop consuming above mentioned and I have replaced calorically equivalent with oatmeal and ryebread, and 3 days later Triglyceride fell to 1.41mmol/L. Triglycerides was the only elevated result. Seeing as Triglycerides are "passengers", is this blood result cause for worry or a natural consequence of above mentioned fat being my main source of energy?
I've been worrying about this. So happy you covered this. I'm vegan and take 1 gram every day. Now I might lower it a little. Appreciate the clarification!
I used to take 5 grams fishoil per day because several CZcams/doctor influencers said optimal DHA/EPA were 1grams each, that required me to take 5 grams overall fishoil, and I started experiencing weird heart palpitations this year even tho I been doing this for several years. My hypothesis is that it was due to oil going oxidized because I opened the capsules and oil smelled really bad. I bought another brand, opened caps, oil smelled fresh and chest discomfort went away, but came back 3 weeks later so I opened the caps again and sure enough, the oil smelled fishy again, so it went in the garbage can. I don't want to waste more money on fish oil now, these caps go bad after few weeks even if they are in the refrigerator.
Thank you- I really needed this! I’m a vegetarian who takes low dose algae derived DHA/DPA supplements. When the link between atrial fibrillation and fish oil came up, I wondered if I should stop those supplements.
The concern I have with supplements is that they aren’t regulated so there is no way to know if they have high levels of heavy metals in the supplements from the manufacturing process. So, then you have to go down this rabbit hole of who has sent for a third party lab results for contamination, then you have to do your own research into if that third party lab is reputable or can be bought off. Etc etc etc. Now you have to concern yourself with if the benefits of the supplement outweigh the risks of the contaminants in the pills and who can do that?
@@tyalangan that’s my concern with food items as well. Just because something is organic doesn’t guarantee that it is free of heavy metals. For example the cacao used in dark chocolate - many of them have high levels of naturally occurring heavy metals, even if they are organically grown and processed.
What I haven’t seen is any evidence discussed of increased risk of atrial fibrillation in populations that have a high fish diet leading to a high percentage of Omega-3 fatty acids in their cell membranes. For example, in Japan. If this is real, is a higher rate of atrial fibrillation observed in the cohort that eats fatty fish daily. Is there any evidence like this?
Well, omega 3 thins the blood also, with all the risk that follows with that so moderation is the key. If you don't eat a lot of fish then omega 3 supplementation makes sense. I choose krill oil since it has less toxins than fish oil.
I know it might sound weird I've been taking nattokiinase for about a year and started getting really bad palpations. I stopped recently and so have the palps....
I had high triglycerides (over 1600) and was prescribed Lovasa, 4 capsules a day (generic equivalent) years ago, to help in lowing them. My continual shift in diet I feel was more the cure for the problem, but the only reaction I got from taking this, was if I bumped my arm on something I'd get broken capillaries. My triglycerides were down to 88 and I asked my doctor if I could stop taking the medicinal fish oil, my concern was I could get internal bleeding. I take a lower does of fish oil now instead of the prescription and no problems anymore.
Hi, i like you podcasts, very enlightening. With regards to this podcast, I've been taking fish oil supplement (2500 mg) for 15 years. I started this after I had a heart attack. Last month I went for a complete heart check. Everything seems to be fine. Guess I belong to the lucky group.
Thank you, Doctor! I take fish oil because I don't eat fish often and I am a higher risk for heart disease. I was diagnosed with AFib with RVR last year and I guess I will chat with my PC and cardiologist if I should even be taking this supplement. You're the best.
Omega 3 precursors (compounds body must convert) to EPA/DHA like in walnuts, etc are not converted as well as one gets older (and depending on other fats you eat).
They’re good sources, but contain different types of omega 3 fatty acids. If you want the same type, get an algae supplement, cause fish get the omega 3s into their system by eating algae
As far as I know, Flax/Chia/nuts are a source of ALA, which is a precursor of actual Omega 3 (EPA/DHA) and is converted at a very low percentage. So seems to me it will be unlikely to cause Omega 3 type reactions.
You get plant based ALA as the only source of omega-3 from walnuts and flax, and ALA does not have the same effect as marine based EPA or DHA. Our brain is made up of a lot of DHA, not ALA. By the way, there is non-animal, algae source of EPA and DHA. No reasons why vegans cannot supplement with EPA or DHA, if they so choose.
One of the many joys of visiting Portugal is eating fish. Perhaps algae based cuisine would be possible, or perhaps already is, as it does in Japan? How is Alga4Food working out?
This 49% increased risk is relative risk right? What is the absolute risk of getting AF in that study? I think it was pretty low, unless I am mistaken. Also, since fish oil is so close to the real thing from the fish itself, is it possible someone gets AF from consuming a lot of the fish itself. Why and why not? I have a can of mackerel that says it has 3500 mg of omega-3. If I were to believe that, eating three of those a week puts me well above 1000 mg a day, i.e. in the riskier category.
I have hated even the smell of fish since forever. I have been taking cod liver or fish oil for years but have it lemon flavored. It has seemed to help my triglyceride to HDL ratio immensely and it may be my imagination but I think it has also helped mental focus. I have tried to eat fish but I just can’t do it.
I’m sorry to throw in a tangent in the comments but I can’t see where else to ask. Would you consider a video about CoQ10 supplements, please? You may have addressed it in a previous statin video but I couldn’t find the info. Hopefully the many statin users would be interested too. For me,I live with ME/CFS and many studies indicate one of the metabolic changes is lowered CoQ10. There’s no treatment for this condition and I’m among the many who desperately try supplements (I have a doctorate in Biology so I’m not an idiot, just very very desperate) There are many like me, especially if you group in the long Covid people.
Is there any clarity on age-dependence? i.e. >65 years of age (or over some age) Omega 3 use has a higher net benefit as risk of cardiovascular incidents goes up with age, but earlier the balance is toward minimal benefit to none.
It might be neither. Fish oil is also quite contaminated with ocean pollutants and heavy metals. We'd have to replicate the studies using algae oil to see if it's actually the omega 3 or the contaminants.
Lack of studies. Too much money for pointless bombings like used in Gaza. Our leaders need to seek peace. Every billion we have can be much better spent elsewhere. We won't need to spend a fortune on defence if we make peace with other nations and hire proper diplomats who listen. Break up the neocon press to. Murdock is a warmonger.
@@toseltreps1101 Dietary cholesterol is only a small fraction of our body's cholesterol. Most of it it's produced by your liver. You can be as thin as Olive Oyl and still have high cholesterol.
I've cut my dose to 1000mg twice a week, since seeing the Afib news. I've been taking FO for 30+ years. It's definitely helped my blood #s. I do have bouts of Afib and flutter. So seeing this latest news has me perplexed.
Yes, fish oil supplements did give me arrythmia, or atrial tachycardia. I was on statins, which eventually poisoned me, but because they gave me joint pain and swelling I was advised to take fish oil supplements. I did this for many years, but between the statins and the fish oil I became extremely ill. Now I have given both up and after 5 months I am finally feeling normal again, and managing my cholestrol with diet, which includes oily fish one to two times a week.
Many people get confused by the numbers. We should not conflate the FISH OIL number on the front of the bottle, say 1000 mg and the OMEGA -3 number (on the front or back of the bottle) say 300 mg omega-3. Only part of that number is what we're after. Only part of that Omega-3 is the vital elements called EPA and DHA which could add up to only 250 mg. So when it is suggested you take 1000 mg it is referring to that last group, EPA and DHA. So I take 4 Softgels, 250 x4 = 1000 mg EPA and DHA,. Thats 4, 1000mg of FISH oil totaling 4,000 mg FISH OIL but only 1,000 mg EPA/DHA.... Am I correct???
That's interesting, thanks. Always thought I want at least 1g of combined, EPA and DHA per day. Would be interesting to see studies that also check for omega-3 index and whether there's a correlation.
Believe it or not my daily dose of Omega 3's was between 10- 15 grams of Omega 3's not ml of fish oil. I saw only good things and I have a complete heart test every year including cardio echogram . Due to the price doubling lately I use 6 grams and if I have tendonitis after weight training I double the dose and usually the pain goes.
I had been eating one can of oily fish (sardines, herring, kipper etc) a week for the last five years & sporadically before that. Until I saw a documentary about Chernobyl & realized the fallout plume squarely hit the Baltic Sea where my fish originates. I researched evidence of contamination but could find nothing. If anyone knows the answer please speak up?
Is AF a life threatening disease though or just a condition? Not specifying this could be deterring the very people who need easily absorbed fish oil (especially cod liver oil) most.
Thanks, i reacted instantly to this news by taking smaller sips of strong fish oil. I started taking it earlier together with the protein meal when it is supposedly more effective. Taking it away from bedtime may have improved my sws also
I love your nuanced approach to these claims, rather than the kneejerk reactions we commonly see online. Nothing is black and white!
Exactly!
So refreshing!

Question: How about older omega-3 trials, I think those should be considered into the complex EPA/DHA equation?
Great Video!
Hi Gil good vid. I wonder if krill oil might differ from fish oil ?

There is so little info about ALA, compared to DHA/EPA.
What is the omega 3/fish oil actually doing to the heart that causes the problems?
Also is there anything about the micro plastics found fish oils?
Thanks for this, I had no idea.

If some is good, more is not necessarily better, and too much is almost always bad.
My omega fish oil is 700mg DHA and 300 EPA and appears to have greater anti inflammatory effect due to Tuna and NZ Hoki fish blend. Any Risk? Thanks
Doc, If a vegan or someone who does not eat fish consumes chia, flax or hemp seeds is there a need or benefit to supplement? (thanks for the video)
I'd be interested whether vegans who eat lots of ALA omega-3 benefit from an algae supplement. I take them currently but I don't really know how much good they're doing me.

Thank you so much for this comprehensive overview. I was hoping you would do this video when almost everybody else ran with one piece of data. 🙏🏻
"One piece of data" is called a datum.
Hey Doc, you mentioned that you take an omega 3 supplement sometimes. Are you comfortable sharing what that translates to?
Do you know if algae oil has higher levels of microplastics than eating fish of fish oil supplements?
I'm 63 and eat a healthy diet and exercise 5 days a week. I eat salmon and tuna every week and take fish oil supplement every day. I brought my cholesterol down from 220 to 130. Works for me.

I have hated even the smell of fish since forever. I have been taking cod liver or fish oil for years but have it lemon flavored. It has seemed to help my triglyceride to HDL ratio immensely and it may be my imagination but I think it has also helped mental focus.
I have tried to eat fish but I just can’t do it.
Algues oil capsules
Doctor.
If someone is supplementing every day with Omega-3 and CoQ10, should they still take an 81mg aspirin? Thank you, sir 🙏
I’m sorry to throw in a tangent in the comments but I can’t see where else to ask. Would you consider a video about CoQ10 supplements, please? You may have addressed it in a previous statin video but I couldn’t find the info. Hopefully the many statin users would be interested too.
For me,I live with ME/CFS and many studies indicate one of the metabolic changes is lowered CoQ10. There’s no treatment for this condition and I’m among the many who desperately try supplements (I have a doctorate in Biology so I’m not an idiot, just very very desperate) There are many like me, especially if you group in the long Covid people.
Does this include krill oil as well?
Do omega3s thin the blood?
Is there any clarity on age-dependence? i.e. >65 years of age (or over some age) Omega 3 use has a higher net benefit as risk of cardiovascular incidents goes up with age, but earlier the balance is toward minimal benefit to none.
Great info. I've been taking Algae oil for years and yes it does raise your EPA/DHA.
So is it the epa or dha that's moreso associated with risks?
It might be neither. Fish oil is also quite contaminated with ocean pollutants and heavy metals. We'd have to replicate the studies using algae oil to see if it's actually the omega 3 or the contaminants.
Lack of studies. Too much money for pointless bombings like used in Gaza. Our leaders need to seek peace. Every billion we have can be much better spent elsewhere. We won't need to spend a fortune on defence if we make peace with other nations and hire proper diplomats who listen. Break up the neocon press to. Murdock is a warmonger.
Probably EPA because it is the one used in that area of the body.
Can you make a video on Berberin for lowering cholesterol. Is it effective!
eat less
@@toseltreps1101 Dietary cholesterol is only a small fraction of our body's cholesterol. Most of it it's produced by your liver. You can be as thin as Olive Oyl and still have high cholesterol.
I've cut my dose to 1000mg twice a week, since seeing the Afib news. I've been taking FO for 30+ years. It's definitely helped my blood #s. I do have bouts of Afib and flutter. So seeing this latest news has me perplexed.
If you've been taking it 30+ years without any instances of atrial fibrillation, then you're fine. Lol
Cronometer says i get 11 grams of omega 3 but i dont supplement or eat fish, thats all from seeds and flax seed oil. am i at risk?
Your body won't convert more than you need into DHA or epa, so you're probably alright. To be sure, you would need to get tested.
What about the rancidity of fish oil? Doesn't it play a role? I wonder whether the studies you mentioned account for this.
Yes, fish oil supplements did give me arrythmia, or atrial tachycardia. I was on statins, which eventually poisoned me, but because they gave me joint pain and swelling I was advised to take fish oil supplements. I did this for many years, but between the statins and the fish oil I became extremely ill. Now I have given both up and after 5 months I am finally feeling normal again, and managing my cholestrol with diet, which includes oily fish one to two times a week.
Many people get confused by the numbers. We should not conflate the FISH OIL number on the front of the bottle, say 1000 mg and the OMEGA -3 number (on the front or back of the bottle) say 300 mg omega-3. Only part of that number is what we're after.
Only part of that Omega-3 is the vital elements called EPA and DHA which could add up to only 250 mg. So when it is suggested you take 1000 mg it is referring to that last group, EPA and DHA. So I take 4 Softgels, 250 x4 = 1000 mg EPA and DHA,. Thats 4, 1000mg of FISH oil totaling 4,000 mg FISH OIL but only 1,000 mg EPA/DHA.... Am I correct???
That's interesting, thanks. Always thought I want at least 1g of combined, EPA and DHA per day. Would be interesting to see studies that also check for omega-3 index and whether there's a correlation.
Keeps coming back to, forget the supplements unless you have a deficiency and just eat real food.
There is almost no Omega-3 fats in modern food, even whole food. Probably everyone should supplement their Omega-3 fats.
Every time I take fish oil my cholesterol goes up, and I have the bloodwork to prove it
Too bad they don’t break out vegan omega 3 vs fish based. A lot of fish oil is contaminated, though the best companies filter it.
Believe it or not my daily dose of Omega 3's was between 10- 15 grams of Omega 3's not ml of fish oil. I saw only good things and I have a complete heart test every year including cardio echogram . Due to the price doubling lately I use 6 grams and if I have tendonitis after weight training I double the dose and usually the pain goes.
I wonder if the whole foods omega 3 comes in, has something in it, you need to eat when consuming omega 3😊
I take it for inflammation. Have ankylosing spondylitis
I had been eating one can of oily fish (sardines, herring, kipper etc) a week for the last five years & sporadically before that. Until I saw a documentary about Chernobyl & realized the fallout plume squarely hit the Baltic Sea where my fish originates. I researched evidence of contamination but could find nothing. If anyone knows the answer please speak up?
You've been eating nucleared fish? 🙀
That is what I'm trying to find out?
My guess is that contamination is probably gone by now.
I gives me heartburn thats for sure and thats with low dose.
Try plant based omega 3.
Majority of fish oils on the market are rancid.
I need it for my blepharitis
Is AF a life threatening disease though or just a condition? Not specifying this could be deterring the very people who need easily absorbed fish oil (especially cod liver oil) most.
Thanks, i reacted instantly to this news by taking smaller sips of strong fish oil. I started taking it earlier together with the protein meal when it is supposedly more effective. Taking it away from bedtime may have improved my sws also
Why not simply increase dietary sources?
CAN YOU SUGGEST BEST VEGETABLE OMEGA 3 SUPPLEMENT-
Algae sourced
Thanks for your balanced viewpoint.
Oh wow! I've had Atrial Fibrillation. I'm not taking fish oil again.
