interesting. should the ratio be done using MCG or IU though? the IU and mcg arent proportional with A and D.. like 5000IU of A is 1500mcg i believe, whereas 5000IU of D3 is like 125 or 250 mcg.Vit D : Vit A according to Ray should be 5:1.
if its done by MCG it would be massive... like 1000mcg d3: 200 mcg A is crazy... if its done by IU it still seems pretty crazy. thats 10000 IU D3 per 2000 Iu vitamin A! what if youre getting like 11000Iu D3 and 6000 IU vitamin A a day
