Vitamins and minerals play a crucial role during intense training periods, as they support overall health and optimize physical performance. For example, vitamin C aids in collagen formation and helps combat oxidative stress, while vitamin D is essential for bone health and muscle function. Minerals like iron are vital for oxygen transport, while calcium and magnesium contribute to muscle contractions and recovery. Adequate intake of these nutrients not only enhances performance but also supports immune function, reduces injury risk, and improves recovery times. A well-balanced diet is essential for athletes and active individuals aiming to achieve their fitness goals.
