| 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)

| vitamin A |
Helps maintain smooth, soft disease-free skin; helps protect the mucous membranes of the mouth, nose, throat lungs, which helps reduce our susceptibility to infections; protects against air pollutants and contaminants; helps improve eye sight and counteracts night-blindness; aids in bone and teeth formation; improves skin elasticity, moisture content and suppleness; and helps reverse the signs of photo-aging. A lack of vitamin A can cause skin to become dry and hardened.
