When the ‘rona began here in the US, the first thought I had was that those with vitamin D deficiencies were going to get ‘rona easier and probably have a harder time if they do get it than those who are not vitamin D deficient. I’m not a doctor by any stretch, but I do know that Vitamin D helps the immune system. It appears that my original thoughts were correct.
I take a multi vitamin daily that has 1,000 IU of Vitamin D3, which according to the label is 250% of my recommended daily intake. The Mayo Clinic recommends 600 IU/day. Mr. Manifold in the post below is quoted thusly:
Essentially everyone in the population should take 4000 IU (100 mcg) of vitamin D₃ per day, and many people should take 10,000 IU (250 mcg).
No links are provided to support his recommendation, however I have heard of others in my immediate circle who are jacking their intake to 4,000 IU.
I surfed around a bit and of course found conflicting info. Does anyone reading this have concrete proof/evidence of how many IU/day a normal, healthy middle aged guy should have?
