How does exercise increase micro-nutrient need?

Exercise increases micronutrient needs due to several factors, including enhanced metabolic activity and the increased turnover of cells and tissues. Physical activity can lead to greater oxidative stress, which in turn may elevate the demand for antioxidants like vitamins C and E. Additionally, sweating during exercise can result in the loss of certain minerals, such as sodium, potassium, and magnesium, necessitating a higher intake to replenish these nutrients. Overall, active individuals may require a more nutrient-dense diet to support their increased physiological demands.
