Vitamin C

Vitamin C is an essential nutrient that helps the body to produce collagen, which is important for the skin, bones, and blood vessels. It is also a powerful antioxidant that helps to protect the body from harmful free radicals. Vitamin C can be found in fruits and vegetables such as oranges, kiwi, and bell peppers. A deficiency in vitamin C can lead to scurvy, a rare but serious condition that causes the gums to bleed and the skin to develop painful bumps and bruises.
