Vitamin C is a water-soluble vitamin, also known as ascorbic acid. The human body cannot synthesize vitamin C, but it is naturally available in some foods, such as vegetables and fruits, and is also available as a dietary supplement.
vitamin C is a physiological antioxidant and a vital nutrient for health, as it helps the body maintain connective tissues including bones, skin, and blood vessels, and has a role in many important and vital functions in the body.
Benefits of Vitamin C
The most important benefits of vitamin C include:
1.It plays a key role in the manufacture of certain neurotransmitters and collagen, and therefore has a vital role in wound healing and healing.
2.Participates in protein metabolism.
3.It plays an active role in immune function.
4.Improves the absorption of iron contained in plant foods.
5.Contributes to the reduction of total cholesterol, bad cholesterol and triglycerides.
6.It prevents the formation of free radicals that cause damage to cells and convert them from normal cells to cancer cells, so one of the benefits of vitamin C is to reduce the risk of stomach, colon, and bowel cancer.
7.Vitamin C plays an important role in bone formation, as it is involved in the synthesis of collagen, which is the basis for bone formation, so normal levels of vitamin C are associated with good bone health.
8.It contributes to the formation and maturation of nerves, and helps speed the transmission of nerve signals.
9.Vitamin C helps in the process of weight loss and lowering body mass index, as vitamin C oxidizes body fat during moderate-intensity exercise. A person may have difficulty losing fat if they are vitamin C deficient.
10.It helps delay or prevent cataracts known as cataracts in the eye.
11.It helps prevent or delay the development of certain cancers, cardiovascular diseases and other diseases, but more studies and research are still needed on this relationship.
