Which nutrient is essential for muscle repair and growth?

Proteins are essential for muscle repair and growth due to their role as the body's building blocks. When you engage in physical activity or exercise, your muscle fibers experience stress and small tears. It is during the repair process that proteins become crucial. They provide the amino acids necessary for the body to rebuild and strengthen muscle tissue.

Proteins contribute to the synthesis of new muscle fibers and promote recovery after exercise, making them vital for athletes and individuals engaged in regular physical activity. While carbohydrates and fats serve as energy sources and vitamins assist in various bodily functions, they do not have the specific role in muscle repair and growth that proteins do.
