Anyone have experience using any nootropics or something else that helped with cognitive function? Some friends I know have tried adderall during school and I was curious your experience with any of these.

almost no risks or real costs I worry a little about risk compensation, or whatever the equivalent is for diet. That is to say, if I feel like I'm all set on vitamins & minerals via pills, maybe I don't need to try so hard to eat my fruits & vegetables anymore...
Worth noting that the above mostly talks above Vitamin D specifically, not multivitamins. D is the only one you do not naturally get from food (ignoring fortified food), and it also as mentioned above one of the cheaper ones. Multivitamins are far more expensive in general.
using a multivitamin daily is considered 'expensive' ?

Sure, but the winter climates in many geographical regions don’t provide adequate sunlight during winter.
I was pretty amazed to Discover that Spirit Airlines is doing round trip flights for $75 to Orlando from my local airport. If you’re in the Midwest in a midsized city that’s cold and dreary in winter there’s a good chance you can find a similar deal.
I know different people have different risk tolerances, but there’s no way I would get on a plane during a pandemic if I don’t have to.

Or just get some sunshine! It's likely there are other benefits, besides just the vitamin D.
Well I mean, in Australia, that leads to skin cancer, so I'll just take some tablets thanks!
Doctors in Australia recommend approximately 15 mins of sunshine a day in Australia.
This is pretty easy to achieve, even in winter, for us... and is unlikely to "lead to skin cancer"

It is fat soluble. You can develop toxicity, and the effects are not trivial: https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-h... It seems based on casual reading of research that more people are deficient than not and dosing to toxic levels is unlikely. But it's not a bad idea to do this under the care of a doctor.
For reference: The level of toxicity listed in your link is 60,000IU per day. Fauci said he takes 10,000IU per day. The bottle I purchased recommends 2,000IU per day. Get your blood work done people.

> This could lead to a recommendation of 1000 IU for children 1 year of age, and around 8000 IU for young adults and thereafter. Actions are urgently needed to protect the global population from vitamin D deficiency.
Then, a person that consumed from 8000 IU to 12000 IU per day and had kidney damage due to high calcium levels in his blood.

> Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity. This level is many times higher than the U.S. Recommended Dietary Allowance (RDA) for most adults of 600 IU of vitamin D a day. Well of course, drinking 100x times the recommended amount of water would be even worse.
A 50,000 IU pill is smaller than a pinto bean. I'm not saying to not take vitamin D, but it can be overdosed with serious negative side effects and the best way to not do that is to consult your physician.

#47It's worth noting that vitamin D has a lot of high-confidence but low-effect results going for it, including a lot of strong meta-analysis over many health outcomes. What I mean by this is that it usually seems to conclusively either do something beneficial, but minor, almost nothing in the case of many studies, and in the case of some others, something very beneficial (as we've seen a few of in relation to covid rec…

We could fortify beer and Coca Cola with it. While it’ll be on the label, I bet 9/10 people can’t rhyme off what is fortified.
(Around here, it’s salt, milk, flour and cereals that get fortified).
Dunno where fluoride fits, but that too.

> and almost no risks This isn't true--especially for Vitamin D. We have several doctors at this point who deal with cases where too much Vitamin D causes Calcium uptake issues and affects cognition and heart function. Vitamin D is NOT something like Vitamin C. Your body easily dumps excessive Vitamin C so you can take fairly massive doses with no real ill effects. Your body has a much tougher time excreting Vitamin…
Yes, this is true and worth mentioning in some cases, as some commenters have noted. Although as far as my knowledge goes, almost all cases of issues are where the patient is taking either an absurd amount (>10x what they should be), or has some other very unusual/absurd health issue. We can only provide disclaimers for so much, but for the sake of completeness, this is worth mentioning and indeed correct.

#50My sister got leukemia while part way through her doctorate. After it went into remission, she was unable to recall new information long enough to read papers and had to put her studies on hold. Eventually a doctor did a blood test that included vitamin d levels, and she was in the single digits (don't remember units but it was supposed to be at least 20). She started supplementing and graduated this spring. Just one data point, but it was pretty clear that remedying a deficiency made a marked improvement in her case.
