On: The Big Vitamin D Mistake (2017)

[cnst]

tl;dr:

* linked abstract recommends 8000 UI for young adults and thereafter;

* my Centrum Multivitamin/Multimineral Adults has Vitamin D3 25mcg (1000 UI), listing it as 125% DV.

I guess I gotta find something extra to get an extra 7000 UI/d to reach 100 nmol/L?
