Anecdotally, I had this discussion with a cardiovascular interventionist specialist about seven or eight years ago when I was managing a team of cardio theatre orderlies in a private hospital. He made the comment, "mark my words, in about five to ten years time there will be a major scare about needing to absorb more vitamin D". His opinion was that the increase in sunscreen usage and the push to avoid skin cancer by…

The NIH guys also did a study that said that even in tropical countries, Vitamin D absorption has fallen dramatically because of lifestyle changes. One of the probable factors is the lust for fair skin. I routinely see people covered from head to toe to help them stay fair skinned, even kids are sent to play covered in full sleeve clothing.

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.

Just to back this up: the journal it's published in has a very very low impact factor of 0.235 (i.e. it publishes 4x more papers that it gets citations, probably most of it's papers are never cited by anyone) [1]. If this paper was considered a big a deal by the wider research community you would expect it to be published in a high profile journal.

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.

Same here, D3 with Magnesium and Calcium since they are co-factors. Should take K2, too. You probably won‘t believe it when I say that my immune system and energy levels are better than any winter before, but thats how it is. I wonder if light therapy is actually just indirect vitamin D therapy.

I take D3, Mg and Ca regularly and I noticed better sleep, reduced anxiety and increased libido. All in all, it makes me feel 10 years younger.

I have been taking 5000IU Vitamin D for the past 7 years, with a little more over the winter months. It's stupidly cheap, I get 360 5000IU capsules for $13, so it has cost me less than $100 over that period. Anecdotally, it was a game changer for me personally. I got less sick during the winter, and my overall wellbeing improved greatly. A word of advice, increase Vitamin K intake aswell. Vitamin D helps calcium abso…

I haven't heard this about vitamin K before - please correct me if I'm wrong, but I don't think we know how the mechanism through which vitamin K reduces skeletal fractures.

Indeed we don't, plus the two forms of vitamin K (phylloquinone and menaquinone) have different mode of action.

They are important cofactor for many proteins, including one called osteocalcin, needed for bone calcification.

This supports my lived experience. Found to be incredibly low in vitamin D, and diagnosed with autoimmune thyroiditis. Doctor said to supplement with 2000 IU being the max per day. After seeing no improvement whatsoever in vitamin D levels, and after talking with others with the same issue, I self medicated to 10000 IU / day. Lo and behold my vitamin D levels went back up and my auto-antibodies went back down.

> incredibly low in vitamin D

How much low, in ng/ml or nmol/L?

If taking EPIC series morbidity and mortality endpoint analysis at face value, best outcomes on average are around 2500 IU/d intake. (In generally healthy individuals.)

So this recommending 4000 IU/d is not too far fetched.

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.

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.

I'm not going to refer to it. If you are curious search on google or HN.

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…

> some of these seem tied to my psychology

Indeed, I personally do see similar triggers, but for me too little exerting exercise and I'm starting to mentally fall apart. This means daily exerting myself. I can skip a few days here and there but then I have to play catch up to "fill back the tank". The trickiest thing for me to notice that was that there's definitely some buildup phenomenon (the "tank" thing), when it's going down I think I'm fine but by the time I start to feel bad it's already too late and filling it back up takes as much time as I skipped exercising, which is even harder since I'm mentally down, driving a nasty feedback loop. As the best exercise for me is outdoors (skateboarding and calisthenics) this puts me in a delicate situation where I'm constantly on the edge during winter time.

As for social experience is a tight rope for me: too much and I'm burning out, too little and I'm crashing hard.
