Vitamin C is involved in many functions of the human body. For instance, it’s essential for the synthesis of collagen, carnitine, and certain neurotransmitters. Also, it’s crucial for protein metabolism and wound healing.

Furthermore, vitamin C may decrease the risk of developing osteoporosis, as it increases the absorption of calcium.[1,2]

Moreover, vitamin C improves the absorption of nonheme iron; the type of iron found in plant-based foods.

In addition, vitamin C is beneficial for the skin. It prevents skin aging and the formation of wrinkles. Also, vitamin C can regenerate other antioxidants, such as vitamin E!

Most noteworthy, vitamin C may delay or even prevent the development of certain cancers and cardiovascular disease. It boosts the immune system and fights oxidative stress.[3]
