Supplements for Muscle Strength And Mass

What the Research Shows

Clinical research indicates that creatine monohydrate has strong evidence for increasing muscle mass and strength, particularly when combined with resistance training. It works by increasing the availability of ATP, the primary energy source for high-intensity muscle contractions. Protein supplements, such as whey or casein, also have strong evidence for supporting muscle growth, though they primarily serve as convenient sources of dietary protein rather than unique pharmacological agents. Other supplements show more varied results. Beta-alanine and nitric oxide boosters (like citrulline malate) have moderate evidence for improving endurance and muscle pump, but their direct impact on long-term strength gains is less certain. Many popular supplements, including various amino acid blends (BCAAs) and legal stimulants, have weak or insufficient evidence to prove they provide benefits beyond standard protein intake. In many cases, research is conflicting or limited by small sample sizes, making it difficult to determine if these products offer a meaningful advantage for the average person.
