Vitamin A

Vitamin A is important for night vision and bone growth. As little as twice the required daily amount of vitamin A can actually increase the risk of bone fractures, while extra beta-carotene, which the body can change into vitamin A, does not increase the risk of fracture. So choose a supplement in which vitamin A is at least 20 to 40 percent beta-carotene. Daily Value = 5000 international units (IUs)
