Protein plays a crucial and well-established role in supporting the muscles body system. Scientific evidence robustly demonstrates that dietary protein provides the essential amino acids required for muscle protein synthesis, maintenance, and repair. Numerous clinical studies have shown that both the quantity and quality of protein intake are important factors influencing muscle mass, especially in populations such as athletes, older adults, and individuals recovering from injury. For example, resistance exercise combined with adequate protein consumption leads to greater increases in muscle mass and strength compared to exercise alone. The Recommended Dietary Allowance (RDA) for protein is set at 0.8 grams per kilogram of body weight for healthy adults, but higher intakes (1.2–2.0 g/kg) are often recommended for those seeking to optimize muscle growth or prevent muscle loss.

Research has also confirmed the role of protein in preventing sarcopenia, the age-related decline in muscle mass and function. Meta-analyses and systematic reviews consistently support that increased protein intake, especially in conjunction with physical activity, helps preserve muscle health across the lifespan. The mechanisms underlying these effects are well understood: protein provides the amino acids required for the synthesis of new muscle proteins, counteracting the natural breakdown processes that occur in the body.

In summary, the use of protein for supporting muscle health is not only traditional but is also strongly validated by scientific evidence.
