    Vitamin C (ascorbic acid) is a soluble vitamin essential for human health. It acts as an antioxidant, protecting cells from damage and is required for bone, skin, and connective tissue. The human body cannot synthesize vitamin C on its own and must obtain it from healthy foods such as citrus fruits, tomatoes, broccoli, and bell peppers. Vitamin C also promotes iron absorption, aids wound healing, and maintains the health of teeth and newborns.
