Saw ads from a group advocating changes to rules, saying you can safely take 25,000 IU/day.


so anything below that is fine

2500iu it's fine

none you should get whatever you need from the Sun.. endogenous D is the only form to have.. forget pills

certainly. Unless you live somewhere that has less than 8 hours of sun in the winter.

Asked the Doc about non-pill replacements for vitamin D. He gave me his permission to move somewhere sunnier

10K is more than safe

Well the safest way to find out how much D3 supplementation you need would be to get your current D3 level checked (blood test for 25-hydroxy vitamin D).

I personally use this vitamin D dosage calculator. Problem is it's in German. Maybe you can Google translate it...

if you really want to take a lot of individual vitamins, i'd go to your doctor, get blood work done, and then ask him. it might cost 100-200$ if you dont have insurance, but its cheaper than fucking up your gainz

is that pic a shop? if not, sauce
