What is Vitamin C?

Vitamin C is an essential water-soluble vitamin our body can’t do without, also known as ascorbic acid. It plays a key role in the healing process and is crucial for forming blood vessels, cartilage, muscles, and collagen in bones. As an antioxidant, Vitamin C helps shield cells from free radical damage and boosts the body’s ability to absorb and store iron.

Since our body can’t produce Vitamin C on its own, we must get it from our diet 4 .
