Vitamin C is a water-soluble vitamin that helps fight free radicals, which can lead to oxidative stress and the premature aging of cells. One of its primary functions is collagen formation, which is important for healthy nails, skin, hair, and joints. Vitamin C also plays an essential role in the functioning of white blood cells, which are vital components of the immune system. It helps to promote cardiovascular and respiratory health and is beneficial for healthy gums. Vitamin C also helps regenerate Vitamin E, allowing Vitamin E's antioxidant properties to be maintained.
