CAN DIETARY SUPPLEMENTS ALONE PROVIDE ADEQUATE AMOUNTS OF VITAMIN D?
Since most multivitamins only contain 400 IU of vitamin D, you need to take two and a half a day to get the recommended daily dose of 1,000 IU, thereby exposing your body to an overload of vitamin A, which, in excessive amounts, has been associated with birth defects and osteoporosis. Vitamin D supplements provide the same benefits as sunshine but, if taken in too large a dose, can cause vitamin D toxicity, whereas sun exposure does not.
