Vitamins play a vital role in everyday physical performance by supporting various bodily functions essential for health and activity. They help metabolize energy, support the immune system, and promote cell and tissue repair. For instance, B vitamins are crucial for energy production, while vitamin C contributes to the healing of tissues and absorption of iron. Deficiencies in essential vitamins can lead to decreased performance, fatigue, and higher susceptibility to illnesses. Therefore, incorporating a variety of fruits, vegetables, and whole foods into the diet is essential to ensure adequate vitamin intake for optimal physical function.
