Hi, I'm Molly Lee, and I'm founder and director of, a holistic health and nutrition practice based in New York City. The recommended daily allowance for vitamin A for healthy males age 19 to 30 is 900 micrograms per day. Vitamin A is a powerful antioxidant which is great for the skin. It's great for your eyesight. And it's also excellent as a natural immune booster. Some of the best natural sources of vitamin A include cantaloupe, carrots, dark leafy greens such as broccoli, kale, and collard greens as well as liver, eggs, and sardines. For women, vitamin A is great because it helps alleviate the symptoms of PMS, helps prevent breast cancer, and also helps relieve yeast infections. If you think you may not be getting enough vitamin A from your diet, taking a vitamin A supplement may potentially be a very good solution.
