A member asked:

20 000 iu vit.a, 4000 iu vit.d3, 12 000 mcg biotin, 800 mg calcium, 100mg niacin, 800 mcg folic acid, daily , is it safe ?

A doctor has provided 1 answer

Safe but: It's safe but not likely to be effective. What are you treating? Not heart disease! And you may increase your risk of kidney stones if you're so inclined.
