Vitamin A – Why You Need It, and How to Get It
Vitamin A is one of the 43 nutrients essential to healthy bodily functions. Unfortunately, your body cannot synthesize vitamin A in the quantities you need. This means you need to eat foods containing vitamin A as a part of your regular diet. Let’s take a closer look at this essential nutrient that is probably lacking from your diet, some of the benefits it delivers, and the vitamin A-rich foods you need to be eating more of.
-
What is Vitamin A?
What we refer to as vitamin A is actually a group of unsaturated organic compounds. They include retinol, lutein, several xanthophylls and provitamin A carotenoids among others. Beta-carotene is one of the most important elements of vitamin A.
Beta-carotene creates that red/orange-ish color found in plants and fruits like pumpkins, carrots and sweet potatoes. Retinol is a natural alcohol and fat-soluble substance that your body converts to vitamin A, and is required for healthy vision.

How Does Vitamin A Benefit Your Body?
The carotenoids, retinol and other compounds found in vitamin A produce a host of health benefits. You probably have been told that you can eat carrots to help improve your vision. That is absolutely correct. Vitamin A, found in high concentrations in spinach, collard greens, carrots, broccoli and cod liver oil, is required in healthy levels for proper vision.
It combines with certain proteins to allow you to properly process low light and color visuals. Vitamin A also boosts your immune system, and is used as a treatment for some cancers. The antioxidants in this essential nutrient also help offset dangerous free radicals in your body that can damage your cells and tissue.
