Note that this is specific to vitamin D, for example 1 IU of vitamin C is 50 mcg of L-ascorbic acid, so 5000 IU of vitamin C would be 250 mg.
One Dr, who owns a huge food formulation company, who I heard speak numerous times said most North Americans, and I suppose it would apply to anyone who lives north enough to have a lack of sun in the winter (especially Canadians), needs a minimum of 10-12,000 IUs of Vit D3 daily. Not sure how that translates into mg.
And now, I'm reading we need K2 and magnesium with that to absorb properly.
I'm hoping I got all that right from memory....
