Vitamin A is another vitamin that falls under the antioxidant umbrella.
Here is the scoop on Vitamin A:
- Vitamin A in it’s purest form is also refereed to as Retinol. Maybe it’s because of the direct effect it plays on maintaining the health of the retina in your eye.
- Also helps your eyes adjust to both low and dark lights as well as day light.
- Helps your immune system stay strong.
- Vitamin A helps to maintain the surface linings of your eye, respiratory, urinary, and intestinal tracts. When those linings break down, bacteria can enter your body and cause infection. Therefor, Vitamin A helps prevent infection.
- Also helps with bone growth and reproduction.
- Helps with development of the embryo and fetus. How much do you need ?
Based on a 2000 a day calorie diet, the FDA recommends a Recommended Daily Intake (RDI) of no more than 5000 IU of Vitamin A.
