I suspect that essentially all people living at relatively northern latitudes have some sort of vitamin D deficiency. From what I know you need to have your face and arms exposed to direct sunshine for at least 15 minutes/day to keep healthy vitamin D levels in the body. Good luck with that in the European/Canadian/Northern US winter.
Vitamin D supplementation to prevent acute respiratory tract infections (2017)

#22I've been wondering why it is that virus infections are supposed to "disappear" in the summer. Obviously the viruses don't actually go anywhere, so I would expect people to get sick year round. Maybe immunity boosting from Vitamin D could be part of the answer.
People spend more time indoors, often with the windows closed. Humidity might also be higher, and temperatures lower, two variables which have an effect on virus viability outside the body.

However, their conclusion that the findings warrant public health interventions and widespread supplementation is arguable. There are real risks and costs to over-supplementation, and the absolute risk reduction they demonstrate (from 42% to 40%) is not large.

That is one hypothesis, though there are a lot https://en.wikipedia.org/wiki/Flu_season#Cause

Assuming it's the BMJ that I know of that's the 'British Medical Journal' which is highly regarded. https://en.wikipedia.org/wiki/The_BMJ

#27Hacker News has gone from the anger to the bargaining phase of grief. 4chan, ahead of the curve naturally, is currently in full blown depression phase.

#29Table 4: > When all studies were analysed together, no statistically significant effect of vitamin D was seen on the proportion of participants with at least one upper respiratory tract infection, lower respiratory tract infection, hospital admission or emergency department attendance for acute respiratory tract infection, course of antimicrobials for acute respiratory tract infection, or absence from work or school…
Said that, the effect of the main outcome is not that big (if I read that correctly, it reduces your chances of getting a respiratory disease by ~4%)

#30Unfortunately I can't find the source, but I read somewhere that it wasn't proven that Vitamin D supplements can improve outcomes after infection has occurred. Can anyone find the source on this and verify?
