Vitamin C plays a vital role in healing and recovery due to its role in collagen synthesis, which is essential for repairing connective tissues and wound healing. It also acts as an antioxidant, helping to reduce oxidative stress, which can occur after intense exercise. By supporting the immune system, Vitamin C can help prevent illness during strenuous training periods. Additionally, proper levels of this vitamin can enhance absorption of iron, which is crucial for oxygen transport in the blood and overall energy levels during recovery.
