Vitamin C plays a critical role in physical health, mostly known for its function as an antioxidant. It helps protect cells from oxidative stress, which can arise after intense exercise. Additionally, vitamin C supports collagen synthesis, essential for maintaining healthy joints, skin, and tissues. Its role in enhancing immune function means it can help reduce recovery times and improve overall performance. Including sources like citrus fruits, berries, and leafy greens can ensure adequate intake for optimal health.
