My family has been taking supplements for many years. We've been taking 1000 mgs of D, 400 IU of E and 10,000 IU of vitamin A everyday. Since we live in a northern latitude, I feel it is important to include these supplements with calcium, magnesium, selenium, zinc, vitamin C, etc. Our new homeopathic doctor recently told us she believes taking D, A, and E are unnecessary because they store up in the liver. She feels this is part of a supplement fad and that we are overdosing on A, D and E which could damage our livers. What is your opinion?
