Which nutrient is considered to be beneficial for muscle repair after exercise?

Protein is considered to be beneficial for muscle repair after exercise because it provides the essential amino acids necessary for the synthesis of new muscle tissue. During exercise, especially strength training or intense physical activity, muscle fibers undergo stress and minor damage. This process, known as muscle protein breakdown, is a natural part of building muscle. Consuming protein post-exercise helps to initiate muscle protein synthesis, which is critical for recovery, reducing soreness, and building new muscle mass.

Protein-rich foods and supplements, such as lean meats, dairy products, legumes, and certain protein powders, can effectively supply the amino acids needed to repair and grow muscle fibers. The timing of protein intake is also important; consuming it within a window of about 30 minutes to two hours after exercise can enhance recovery outcomes. This role of protein in muscle repair makes it a key nutrient for athletes and individuals engaging in regular physical activity.
