Vitamin C, also known as ascorbic acid, is an essential vitamin for the human body possessing high antioxidant properties. Some of its primary benefits include:
- Immunity and wound healing
- Growth and development of all body tissues
- Collagen formation, including the maintenance of cartilage, bones, and teeth
- Absorption of Iron
Vitamin C is probably something most have heard of being an importance since an early age. Just as it benefits supporting normal growth and development during early life stages, it continues to benefit life expectancy and preservation as we age.

Vitamin C is perhaps historically best-known for the treatment and prevention of scurvy, though it has many other roles in the body. For example, vitamin C catalyzes or is a cofactor in eight enzymatic reactions involved in the synthesis of collagen, the nutrient carnitine, and several neurotransmitters necessary for the proper function of the brain.
In the contemporary context, vitamin C is best known as a potent antioxidant. In addition to its intrinsic activity as an antioxidant, vitamin C has been shown in in vitro trials to regenerate alpha-tocopherol (vitamin E). As an antioxidant, vitamin C combats the detrimental effects of a group of compounds called radical oxygen species that, when produced, degrade the lipid membrane of the cell and may cause internal damage. By “scavenging” these free radicals, vitamin C and other antioxidants form a defense against excess cellular damage.
