Muscle Mass and Strength
Supplements studied for muscle mass and strength.
Overview
Soy protein combined with strength training may support muscle and strength gains across seven studies, performing similarly to whey or animal protein in many trials. In some populations, such as older women, adding soy protein to the diet may improve strength gains from exercise.
L-Carnitine at 2 g daily for nine weeks may improve bench and leg press strength and reduce exercise-related blood lactate without changing muscle size in men doing resistance training. The heatmap and evidence reviews below compare these supplements.
