Vitamins play a crucial role in supporting peak physical performance by ensuring the body functions optimally during exercise. Essential vitamins, such as vitamin D and B vitamins, contribute to energy production, red blood cell formation, and muscle function. For instance, vitamin C aids in recovery by reducing oxidative stress, while vitamin E acts as an antioxidant to protect cells from damage. Deficiencies in these vitamins can lead to decreased performance, increased fatigue, and longer recovery times. Therefore, a balanced diet rich in vitamins is vital for athletes and active individuals aiming to enhance performance and maintain overall health.
