What is Vitamin A?

Vitamin A is a group of antioxidants that can occur in a variety of forms.

It is found as retinol in animal tissues and carotenoids in plants. Retinol can be directly used by the body, while carotenoids (most commonly beta-carotene) are converted to retinol after ingestion, but only about a third of that ingested. Carrots, sweet potatoes, spinach and Kale are all good sources of carotenoids.

Vitamin A plays an important role in vision, the formation of bones and teeth, enhances immunity, protects against cancer formation and assists in the maintenance and repair of mucous membranes.
