Protein-containing supplements, either ready-to-drink or as powders to be mixed into water, are marketed as aids to people recovering from illness or injury, those hoping to thwart the [[sarcopenia]] of old age, to athletes who believe that strenuous physical activity increases protein requirements,~~<ref name=IOC/>~~ to people hoping to lose weight while minimizing muscle loss, i.e., conducting a [[protein-sparing modified fast]], and to people who want to increase muscle size for performance and appearance. [[Whey protein]] is a popular ingredient, but products may also incorporate [[casein]], [[Soy protein|soy]], [[Pea protein|pea]], [[Hemp protein|hemp]] or [[rice protein]]. A meta-analysis found a moderate degree of evidence in favor of whey protein supplements use as a safe and effective adjunct to an athlete's training and recovery, including benefits for [[endurance]], average power, [[muscle mass]], and reduced perceived [[exercise intensity]].

According to US and Canadian [[Dietary Reference Intake]] guidelines, the protein [[Recommended Dietary Allowance]] (RDA) for adults is based on 0.8 grams protein per kilogram body weight. The recommendation is for sedentary and lightly active people. Scientific reviews can conclude that a high protein diet, when combined with exercise, will increase muscle mass and strength, or conclude the opposite. The International Olympic Committee recommends protein intake targets for both strength and endurance athletes at about 1.2–1.8 g/kg body mass per day. One review proposed a maximum daily protein intake of approximately 25% of energy requirements, i.e., approximately 2.0 to 2.5 g/kg.
