There was a strange country where the pure Omega-3 "fish fat" was extremely popular, almost every child was fed this in childhood.

Then these kids grew up. And they became tens of millions of idiots who put cans of water in front of TVs so that some charlatan would "charge" this water.

So this Omega-3 is proven not to help the brain. It maybe even harmful. The second assertion has not yet been refuted.

So basically once your body has all the nutrients it needs to grow or make the things it needs to make, it makes them. Even more extra stuff it doesn’t need, it doesn’t use. Makes sense. This also appears to apply to the immune system. There’s zero evidence that supplements that are supposed to “boost your immune system” do any such thing. Yes your immune system functions best if you have good nutrition, but that’s i…

I guess the argument would be that you don't know for sure whether your diet does provide all the nutrients your body needs, so supplements could be used to fill in any gaps. The assumption being that your body will just dispose of any excess safely.

The assumption being that your body will just dispose of any excess safely.

Well worded. From my personal experience, this assumption is dangerous.

About 20 years ago I was having elevated AST/ALT liver enzymes three tests in a row indicating liver damage. Doctor ordered every test to see what was going on but everything came up negative. She asked me if I took a multivitamin which I did. She told me to stop.

Haven’t had elevated liver enzymes since.

I don’t understand the author’s reading of the literature they cite. They refer to “isolated studies” and then link to a systematic review of 25 studies. They also linked to the same review twice for both memory and attention, which I assume is a mistake, because the review only supports the claim about memory. But none of these studies are about “brain-boosting”. They’re about preventing or reversing cognitive decli…

Thanks for the feedback: will update the second link to point to the correct source, and I think "isolated findings" would be a more accurate word here.

I agree that many of the studies are about cognitive decline, but there's also research on improving cognitive function, which would probably be closer to "brain boosting" category you mention.

For example, from the first source I listed, "Six trials (including 1757 participants) assessed executive function, 5 trials (including 1426 participants) assessed effects of LCn3 on processing speed, and 11 (including 5698 participants) assessed memory. Meta-analysis suggested little or no effect for all of these measures (as well as the subcategories of memory, all moderate- or low-quality evidence; see Supplementary Material for further information)."

I find it really common when researching the benefits of X to run across articles citing research that "X does nothing in healthy people" seemingly to discredit the idea that taking X is a good idea. But if you have a deficiency that research isn't really relevant. Gotta read the qualifiers.

You will want k3 if you take d2. Highly recommend getting tested for D deficiency. Source. I used to have crippling migraines almost every day. I don’t anymore.

I used to get crippling Seasonal Affective Disorder every year, got tested, was badly deficient, and now don’t anymore.

How did you all resolve the deficiencies? Can you link any product you took? I am in need of Vitamin D.

That’s a perfectly fair point, I took Vitamin D during lockdown because I wasn’t getting enough sunlight. I’m just saying that it makes sense that beyond satisfying your body’s needs there’s no higher plane of health that supplements will take you to.

What was in that multivitamin you took? Interesting anecdote but I worry you are throwing the baby out.

I think the "boost your immune system" things are just common deficiencies in modern people. If most people don't get enough vitamin C or D in regular life, then the advice to boost their immune system with a sufficient does to be non-deficient would function to boost their immune system to a normally healthy level.

You’ve mixed them up - it’s D3 with K2.
