Essential vitamins play a crucial role in athletic performance by supporting energy production and recovery. Vitamins such as B-complex are vital for converting food into energy, whereas vitamin C aids in tissue repair and immune function. Vitamin D is essential for bone health and muscle function, impacting overall strength and endurance. Moreover, antioxidants like vitamins E and A protect cells from oxidative stress during high-intensity exercise. Maintaining optimal vitamin levels ensures that athletes perform at their best and recover effectively post-exercise.
