Does anyone know the ratio of Ca to Cholecaliferol in Reptile supplements? Is there a specific IU per gram that should be used? (I’m trying to construct my own supplements for my tortoises).
Susan Susan Donoghue, MS, DMD, DACVN published an amount per KG of tortoise. It's a chapter in Doug Mader's book -- I think.

i'm not aware of any ratio for calcium to d3 , I believe calcium to phosphorus is somewhat critical …….. there are quite a few sources with estimated safe doses , and toxic dosages , for d3 supplementation
