Does Fish Oil (Omega-3) improve Brain Performance? [Study 123-129 Analysis]

[@Physionic]

Assuming you want to try it, here are three of my recommendations: Highest quality, liquid form*: amzn.to/3lvhN5W Cheaper, Good quality, Pill form*: amzn.to/3JXK7qX Vegan friendly*: amzn.to/408SXI9 *This product is independently lab tested to ensure the amount listed is correct (and is free of heavy metals); this is also an affiliate link, but I have no relationship with any of these brands.

Ginkgo Biloba was perfectly pronounced. Please also take into account that sunflower oil is extremely rich in Omega-6 acids - since Omega-3 and Omega-6 use the same converter, that sunflower oil will actually have a negative impact compared to someone not taking any sunflower oil. The ratio of Omega-6 to -3 in sunflower oil is 126:1, so the intake of sunflower oil literally floods the body with Onega-6 acids, so that the intake of an Omega-3 capsule hardly stands any chance against the massive amount of Omega-6 to get through that needle eye and be converted - the sheer amount of Omega-6 just blocks it. So it is sad to say, but the set up of that study was less than ideal.

[@petercallison5765]

This may worth further investigation: Some treatments only work in combination like piperine and cucurmine. Seems to be the same with Omega 3. I found this after a search on chatGPT as I forget where I first saw it: According to 1, alleviating cognitive decline with omega-3s may only occur with adequate B vitamin levels. Vitamins B 6, B 9, and B 12 break down the amino acid homocysteine, allowing for omega-3s to be incorporated into the membranes of brain cells. As we age, our brains progressively atrophy (deteriorate, shrink, degenerate), leading to cognitive decline. According to 2, researchers publishing in the European Journal of Nutrition have discovered that a combination of B vitamins and the omega-3 fatty acid DHA is linked to decreased cognitive decline in older individuals. A different post-hoc study showed that a combination of low homocysteine, an amino acid that is broken down by B vitamins, and omega-3 supplementation is associated with reduced cognitive decline.

[@mertonhirsch4734]

Do you think men and women should get different ratios of EPA and DHA? There is a brand that supposedly flips the ratios for men from one to the other, a serving providing about 2.2 grams of DHA and .9 grams EPA. The brand you listed has about 1.5 EPA per 1 DHA.

A million viewers? That would be nice, however, the average person who would love to know the results of these experiments is missing the educational background that would make it very easy for them to listen to the complex information provided, not to mention the time needed. What I believe is really being presented here is a fine lay education in the methodology used in these kind of experiments, as well as how to read the data. The believable results are the reward for slogging thru the methodology and data. This old once-a-vegan will continue eating a can of sardines twice a week, yes, for the protein, but mostly for a natural source of B12 and the EPA/DHA omega 3s. BTW, that practice makes me a Flexitarian, which, statistically, is a group that lives the longest. I am betting that also includes the longest healthy life even as I have found no proof of such.

Great in-depth analysis! Yah I would agree Omega-3 has some mild benefits especially on an anti-inflammatory front, though I wouldn't rely on it for large memory effects. I take it mainly to decrease triglcyerides and some anti-inflammatory effects, though not too much, because it can increase your LDL's especially in those who already have dyslipidemia.

[@kenadams5504]

I thought ldl is associated with better longevity .....as long as the ldl particles are not the damaged type, ( from oxidation and glycation).

Omega 3 is a composition of many different Acids. Essentially, DHA has been shown to raise LDL, EPA does not.

[@sabincioflec8413]

Cool video, thank you for it! A few things from my point of view, the placebo is usually sunflower oil that has 2.4g of omega 6 in 4g, i think that could influence things a bit. Also maybe just like fasting has been shown to normalize some parameters in individuals but does nothing to healthy people, i think that omega 3 does the same with people that really need it. Bill Harris has a ton of information on this and, from my point of view, if you'd get a study for people with omega 3 index of 3% that is the average in USA, to the optimal 10% then you'd see a lot of improvement, but most people there probably have health issues. My main concern however with studies like this is that in nature, omega 3 doesnt come alone so we don't really know what effect the other nutrients have, maybe omega 3 needs something else to get in the brain and really affect cognition. I'd much rather see a study with 4-5 g of omega 3 from real food and see if it improves biomarkers and mental health. Granted it's hard to have a placebo group but i bet smart people could find a way. Also an underrated omega 3 source is beef/pork brain and it has tons of choline too.

[@Physionic]

Thanks, Sabin. I agree on your criticism of the placebo. It would have been better to look at something more inert. That said, we can control for changes by using a statistical analysis on the placebo measures. Additionally, not all the studies used sunflower - it was a minority, so if we group the studies together, that minority gets drowned out by the larger data set. I actually looked at omega-3 index, but left that in my Insider's version. You're right - it is possible there may be something else that could help omega-3's enter the brain - I'd be interested to learn some of those mechanisms. Although, it would be easy (although invasive) to test. The cerebrospinal fluid could be measured for serum omega-3 to determine if there is a brain absorption disparity.

[@sabincioflec8413]

@@Physionic I think i remember something about ApoE 4 that has big problems with omega 3s to get in the brain even though blood values are good, so might be something related to insulin i think. My theory is that ketosis is really important for omega 3s but i have no proof of that :)) kzbin.info/www/bejne/Y5eQdHmHrcaIj5Y Pretty sure you know about this interview but in case you don't know, the guy seems to know what he talks about "Dr. Bill Harris is the author of more than 300 scientific papers on fatty acids and health. He is a professor in the Department of Medicine in the Samford School of Medicine at the University of South Dakota, the co-inventor of the Omega-3 Index, founder of OmegaQuant Analytics, and president and founder of the Fatty Acid Research Institute. " He has studies with 25g of omega 3s from salmon oil and it showed some benefit to healthy people but not that much, but when given to people with high triglycerides/ldl seems to have really big benefit. Also seems to benefit LPS induced inflammation , so who knows how it interacts with the microbiome too. So many questions, so little good studies 😄

[@Physionic]

APOE was looked at in several of the studies - no effects found, but that may be underpowered. I've seen some of it. I'd need to go through it again.

[@mballer]

Reverse engineering these studies and finding the people who were the most improved, then finding what they had in common would be a way to figure out what was going on. If most participants were lacking in multiple nutrients supplying just one shouldn't be expected to do much. Or if they were eating diets that were pro-dementia producing, which we might expect since they were in decline, would be a tug of war against anything positive. The way medical studies are designed is bizarre. Some people improved but let's just ignore them and move on to another study.

There is a fish oil paradox in cardiology where a small dose helps but a large dose increases risk.

There has never been demonstrated a health benefit with more than about 4 grams Omega-3 per day.

[@sasharamirez2335]

Here's a random thought as I rewatch this. I might be in the complete minority of one here, but firstly I see your analysis as everyone else likely does, quite incredibly detailed and objective. Invaluable. Top quality work. Now to my minority of one thought. I really really would like to get all my nutrition from actual food. So my current approach to omega-3 nutrients, is to eat wild caught frozen salmon that I cook obviously. Fish starts to rot the moment the fish dies, and out of water it's quite a rapid process. Frozen at the source is the only way to go in my opinion. I also eat canned sardines, and herring. Is this the best, most pragmatic approach for someone who wants to eat a truckload of omega-3 fatty acids? Is there a better way? Every time I see you come to a positive, high confidence, conclusion about one nutrient group or another, my first thought is, how do I eat this? Our seas are getting polluted. Our soil is stripped of it's minerals and diverse organic material. Farmers spray by the metric shit ton, NPK on the growables, leaving out the myriad dozens of other things that nature normally supplies. The NPK dominance leaves the crops weak, so they require massive amount herbicides and pesticides to allow them to come to fruition. Our livestock eats these products, the soy, the corn, the wheat, or the byproducts of these things more often, and all this stuff is deficient, so the animals are deficient, they get injections of all kinds, ammendments to their feed, and they're selectively bred to come to maturity in a fraction of the time nature intended. Grass fed is modestly better. But wild-land foraging animals are astoundingly better than the best commercial grass fed. This has been shown anecdotally by farmers who have open land, and allow their non-commercial cows to free roam. The meat that is harvested for the family, some of it has been tested, an the omega-3 to omega-6 ratio is marvelously superior to the best 100% organic grass fed and grass finished commercial beef. It's more on par and competitive with wild caught fatty fish in near pristine waters.... some day, these types of food sources will be more prized and valued then we can imagine....

[@grainiac7824]

You're correct in serial 3s and 7's.

One of the potential causes of difference in outcomes can be the different antioxidants used to preserve Omega 3s (asthaxanthin, rosemary extract, vit E...). These are, for sure, not neutral.

[@aaronlatif52]

@@firpofutbol The popular 2 hour podcasts are from my observation either informal and comedic and/or rely on quality guests or famous/semi famous host. Its not really a matter of being succinct or not IMO. Its really just that most people would watch a 10 minute video or shorter to understand something and for a channel to blow up on youtube, its typically around this time length. Podcast are a different story, sure many can blow up right from the start (but thats usually from exposure on bigger channels and what not) but most more academic or scientific focused are built over years of quality content. But IDK things just happen sometimes regardless of what I think or project - maybe this channel will blow up but I have my doubts do to a few factors - length being a major reason but lack of excitement and building interest probably being a part to - like selling why this or that is important or demonstrating more excitement, shock, emotion. It comes off as dry info for the most part and that doesnt typically sell/blow up especially at longer lengths.

[@firpofutbol]

@aaronlatif52 I feel the same way about the Andrew Huberman podcast, which are often 2+ hrs long. Way too long for me so Physionic's feels like it covers enough detail without the wasted conversation that comes in other formats. As a nurse, having taken anatomy and physiology, I find the content fascinating because I understand the context. Although I don't share your view of the content feeling dry in Physionic, I know what you mean because I find Huberman to be extremely dry and hard to listen to. It's all subjective. Personally I've been hooked on this channel since I discovered it.

[@CannabisRex]

Re: Liquid oil recommendation--Nordic Naturals also sells an identical product for less than half the price of the Ultimate Omega you recommend. The cheaper one is somewhat more than half the strength of the Ultimate bottle--so "Regular" at 1560mg/tsp for $22.06 versus Ultimate 2840mg/tsp for $61.16 --both in 8oz bottles. Thus you can spend $44.12 on two bottles and get more EPA/DHA from the same producer than if you spend $61.16. Have I missed something here?

Thx Nic for the insightful videos. Wrt Omega 3, did any study measure the effect on cholesterol? Thx in advance

[@scottmcdonald5237]

I noticed that a problem with fish oil studies in that oils go rancid, sometimes rapidly and, I'm guessing here, perhaps simply by not storing in a fridge or freezer by the study participants. Thus long term studies would show, at best, an initial positive effect and no long term effect. As an omega fatty acid degrades over time, it's easily assumed that its potency declines as well. Did anybody control for this by: Duplicating the storage environment(s) and test the pill contents at least weekly. Supply fresh pills ~weekly. Otherwise, failure to control for oil degradation is what's actually being tested.

[@mballer]

Someone should setup an industry standard when using omega 3 oils in studies. For example, all oils to be refrigerated.

[@teddybearroosevelt1847]

What people tend to forget is that while omega 3 may be beneficial in principle, the fact that there are many supplements that come from ( farmed) fish full of heave metals, antibiotics and other medication and with capsules that don’t keep air out well so that the oil becomes oxidated. Makes you wonder if it’s even a good idea to take this supplement in the first place. I’m currently eating caught fish 2-3 times a week and I take a high quality algae based supplement on the other days.

You were quite fast on that end part of your vid when it is precisely these few seconds that would deserve an hour for us to understand better your conclusion. Your conclusion was more or less what I already believed though the term "omega 3" need to further clarification (long chain and short chain etc).

[@Physionic]

I would really push back on your publication bias point. There's literally nothing else to say on the topic. Additionally, only 3 or so studies were identified as having potential bias - I'm not sure what else I could have said on that front. Plus, keep in mind, even if I had an hour's worth to say on publication bias (which I absolutely didn't - it's pretty cut and dry) - I doubt 99.9% of people want to hear me drone on about a topic they have zero interest in. I covered all the major points and moved on.

[@arallskiant9923]

@@Physionic as you said 1:31:45 there is most likely some publication bias. 3 studies were eliminated because thought to have potential bias but that are only the most obvious ones the funnel plot indicate that probably other studies has been eliminated (showing negatives) even before the meta-analysis, that probably skewed the data. the things to say was not so much in those 3 studies but maybe a bit, there is the somewhat counter-intuitive fact that once removal of some publication bias the hedges'g increase for memory, the thing you said about p-value, maybe p-hacking etc. overall I agree with you I was a bit greedy indeed, my statement of an hour was hyperbolic as I felt the most interesting things to me started here so it was totally not a critic just my greed talking. I obviously totally get you not having the time for that and I'm alrealy thankfull for the point you have covered.

My children turned out gifted I attribute this to outside a lot……vit D. I would have added omega 3 especially in cheap sardines during pregnancy. Good idea to marry the smartest man you can find.

Try sardines yourself n of one. Add me to yours amazing . The supplement faulty degradation occurs quickly.

fish oils in tabs and gels are about as fresh and rancid as vege seed oils when you buy them in clear plastic bottles on store shelves. dont touch em.

[@arallskiant9923]

algae EPA/DHA is best (cost cents too, many brands or real seaweed food). Bivalves are vegans friendly but not as healthy( it is still animal food so same habitual deadly flaws) . I personnaly found EPA/DHA useless though. Long chain omega 3 might has its risk too so some choose to avoid it and that's okay (a useless hassle if seaweed are part of your previous habits), everyone is able to elongate ALA enough to get the long chain (which is in the order of mg unlike ALA in grams) in different degree. ALA as other benefit too.

[@Physionic]

I would disagree. All the independent lab testing results I've seen have shown algae fish oil to be extremely under dosed. Those that were more highly dosed had other issues, like not containing the amount marketed. So, that may be why you haven't experienced benefits, but that's speculation on my part.

[@arallskiant9923]

​@@Physionic thank you for your answer. you disagree with what? it is a bit fuzzy but as it seems like you are just disagreeing with my personal/anecdotal habit of me founding useless to take these pills (not with higher claims like the existence of algae pills etc) and that is fine but I am not sure of what to say. though when you said that fish oil were extremely underdosed in lab test you kind of goes my way... I do not take fish oil as it is not ethical. Not just because of problems regarding the business of fish oil on health (like dosage or rancification hiding with flavor, pollutant control etc). But, to be clear, the same fatty acid in algae pills are ethical and I still do not take them either. Also benefits is not something one person "experiment" that is anecdotal fallacy. am I supposed to do a pool of memory test and just to witness some benefit and then attribut it to this new pill (and also artbitrarly attribute any downside to it). whether or not long chain omega 3 as some degree of possible health benefit it can still be deem useless for someone to integrate this new habit into his life (many little things are healthy to do to in various degree).

[@Physionic]

Gotcha - I was disagreeing with algae EPA/DHA being the best. To your second point, I agree - it's tough to test on yourself, but considering you mentioned you were able to tell if made no difference, I figured you'd be able to test it again in a similar fashion to the first time.

[@arallskiant9923]

@@Physionic I guess you found algae equal to fish oil then But Algae being the best has more to do with other science than your subfield of biology obviously, though even when it come to fitness there is some argument to be made for algae but if quality (pollutant control etc) is there, it is indeed mostly same despite the sources of fish oil being objectively disgustingly dirty/shady and unethical. One is able to tell if a thing made a difference or not with the litterature as anecdotaly there is many bias (though it can have its wheight indeed if one has specific scientifically related problems and his followed by a physician etc but I am fine) and looking at how a new habit fit into his lifestyle etc and calculating cost/benefit overall. So your suggestion if people feel that marine oil does not have any effect, is too increase the dosage, that can be dangerous at some point but I can see your point indeed despite the litterature showing that healthy people will be unlikely be able to see the benefit if/when there would be one.

Learn how to make points . Long talk is boring. Human attention at best is 20 minutes. Good topics but who is your listeners? The observer in Quantum physics , listeners in physionic.

Then it would have been a different kind of channel. People read books and we see an increasing popularity of long form content (podcasts)? I love this channel because I get to follow the train of thought. If shorter is better you might consider TikTok.

Your attention span maybe 20 minutes and this is commonly the case based on lifestyle and diet and personal mindfulness practices. The healthier I am, the longer my attention span.
