I try to keep the A : D ratio around 5 : 1, sometimes even 10:1.Why this amount?
I get negative reactions to D or A alone but together I tolerate them very well.
I think that supplementing A and D together in the right ratio reduces the risk of toxicity of both.
"The hypothesis further proposes that vitamin A protects against the toxicity of vitamin D by decreasing the expression of vitamin K-dependent proteins and thereby exerting a vitamin K-sparing effect."
Vitamin D toxicity redefined: vitamin K and the molecular mechanism.
