Vitamins and minerals are essential in supporting overall fitness and health. They facilitate countless biochemical processes crucial for energy production, muscle contraction, and recovery. For instance, calcium and vitamin D are vital for strong bones, while antioxidants like vitamins C and E help combat oxidative stress induced by intense exercise. Additionally, minerals like iron support oxygen transport in the blood, enhancing endurance. Adequate intake of these micronutrients ensures that the body operates at peak efficiency, promoting optimal performance and reducing the risk of deficiencies that could impair physical activity.
