Steve Gibson has talked about this issue in the past: https://www.grc.com/health/vitamin-d.htm (And please, yes we get it you are a smart ass, don't link to the page that you are going to. The horse has been beaten to death.)

Now I'm curious as to what page you're referring to.

Anecdotal I know, but I've heard of a couple of different areas where a a medical professional recommends Vitamin D supplements to their patient.

Someone I know has been told to take vitamin D to help manage relapsing remitting multiple sclerosis[1]

Another person has been recommended vitamin D to help with conception.

Seems to pop up all over the place.

If you intend to take vitamin d I read in various places you should also take magnesium and probably vitamin k as well. And less calcium. Everything is interconnected. https://www.precisionnutrition.com/stop-vitamin-d

I recently started taking 3000mg of magnesium per day as magnesium chelate. The bottle recommends three capsules per day for muscle spasms / cramps. Historically, I have a couple of basic assault charges, an assault with sexual intent charge, I was charged with two counts of trafficking a controlled drug (later dropped). Shortly after I commenced taking six capsules a day I started feeling a lot less psychotic .

Yes, my theory why lithium is so effective is the body can use it to replace the magnesium we are all deficient in.

I've been tracking my depression for a few years now, and I'm amazed at the number of things that can trigger a depressive episode. I used to think I had a disease called depression, but it now appears that I had arrived at a collection of various life circumstances that made experiencing depression on any given day more likely for me. Some of the main triggers have been: - Attempting to proceed without a plan - Push…

> Bad sleep (I now use the calculator at sleepyti.me and have had great results) Interesting site, didn't knew about it! I've checked it out, and as I wake everyday at 7am, it suggests me four different hours: 10pm, 11:30pm, 1am and 2:30am. What I find interesting is that none of it matches exactly the 8h average sleep value. As you say that you have had great results, could you comment a little bit on that? Thanks!

I often push it too far and stay up till 3AM and wake up around 7:45 and then I can just proceed normally that day. I'm a bit melancholic on those days, but that's it :D

I was a bit surprised that this site suggested the 3AM as an option to fall asleep.

Word of advice: don't take vitamins ADEK without advice from a physician for extended periods or in high doses. These are fat soluble so you can have too much of them.

This should be reiterated: Please consult a professional before drastically altering the chemical composition of your ephemeral body. I know it sounds downright crazy, but it's possible that someone who's studied medicine and practiced it for years, actually knows better than random anonymous forum users.

>>I know it sounds downright crazy, but it's possible that someone who's studied medicine and practiced it for years, actually knows better than random anonymous forum users.

As the link in the OP actually denotes, no, that's not always the case.

Bodybuilders and performance trainers - as well as Soviet Union sports scientists - have known for decades that Vitamin D supplementation is vital. This has been rejected by a significant number of general practitioners and other medical experts who are and were anti-supplement simply out of rote thinking.

Yes, people should be tested for their levels. But this simply isn't feasible for poor people, and telling them to get serum tests for Vitamin D before taking a lower-bound amount of the cheap supplement from the grocery store is ridiculous.

This article seems to be a low quality review of other research with a clickbatey title (full text here: https://www.jpmph.org/journal/view.php?doi=10.3961/jpmph.16.... ). Pubmed is sort of like arxiv.org and the fact this has an nih.gov base url should not be taken as an endorsement of it by the NIH. That said I do actually believe that more then the recommended amount of vitamin D can be beneficial and the recommen…

>>Pubmed is sort of like arxiv.org

What? It's nothing of the sort. Pubmed is not a preprint server. The paper in question was accepted by a journal. The quality may not have been great - I agree - but it is not like the archive at all.

For Vitamin D 1IU is 0.025mcg. 8000IU = 200mcg My box of vitamin shows a Vitamin D3 content on 5mcg/pill (noted as 100% of recommended daily intake). Time to change pill I guess...

Off by a factor of 10. 0.025mcg * 8000 = 20mcg

no... 200 is correct.

If the recommendations of this study become the guideline, it may validate the other studies suggesting that nearly everyone is deficient in magnesium, which is a co-factor in the Vitamin D / calcium cycle. AFAIK (and correct me if I'm wrong), the vitamin D metabolism requires magnesium, calcium, vitamin K2, and vitamin A. K2 in particular needs special attention, as it's the hardest of the substrates to get.

It's not a study. It's an article that cites other studies.

It has an abstract, so I figure it's a meta-analysis and not just an article.

Throwing in my two cents. I used to suffer from seasonal mood swings, since taking a daily multivitamin this has been the best winter of my life.

Call me skeptical, but I severely doubt multivitamins can help with depression of any kind. Maybe placebo. TFA is about mortality.

>>severely doubt multivitamins can help with depression

If the multivitamin has sufficient Vitamin D, it definitely can. There are plenty of research papers indicating at least some sort of link, and Soviet Sports scientists have known about the performance benefits for a long time, well prior to oral supplementation (they irradiated athletes).

Here's one of many metasources available.
