Men do have to worry about retaining too much iron. Women before menopause typically don't have to worry as they lose a bit of blood every month. https://www.winchesterhospital.org/health-library/article?id...
If you're a man, you can give blood to get this effect. I believe there was a study linking this to a decline in diabetes risk (or something like that).
Its not clear they compared to any control group?
It's not a study, you can't have a control group in a retrospective review, you can only sort data from the data set. You can complain about the small N, though. > Among ICU subjects, 11 (84.6%) had VDI, vs. 4 (57.1%) of floor subjects. Strikingly, 100% of ICU patients less than 75 years old had VDI (n=11; Table 2).
Makes you wonder if there is a correlation to Vitamin D insufficiency due to lack of sun light.
Is there any evidence multivitamins are harmful (not just that there's no proof they help improve health?) It's because of stuff like this I take one. Maybe I'm wasting money, but absent a harm I feel it's worth it to hedge my bets.
Certain vitamins and minerals. Fat soluble vitamins can build up to the point of causing problems. Excess of iron and magnesium may have negative effect AFAIK.

i suspect VID correlates well with COVID comorbidities, like a sedentary lifestyle, hypertension, and weight problems. the opposite is also probably true, that people with good vit D levels correlate with healthier lifestyles and fewer comorbidities.
Interesting thing... Vitamin D is one of those things that, when vitamins come up on HN, you will often hear the refrain that "it's the one vitamin that large numbers of people are actually deficient in and ought to supplement." I've heard that many times over the years and I have taken a Vitamin D supplement on and off (more off than on) over the years. When this COVID-19 thing first hit, I had a physical scheduled…
I was Wrong on the internet (lots of food has vitamin D including Eggs and Mushrooms): Vitamin D supplements may not be absorbed as digestion isn't the normal process for obtaining it.

Does anyone know of a rule of thumb for how much time spent in direct sunlight is equivalent to a Vitamin D supplement? Is an hour per day (on average) sufficient?
