Protein supplement


A protein supplement may be a dietary supplement or a bodybuilding supplement, and may take the form of a protein bar.


Muscle buildingEdit

In untrained individuals, changes in lean body mass and muscle strength during the initial weeks of strength training are not influenced by protein supplementation.[1] Protein supplementation promotes greater gains in lean body mass and muscle strength for both trained and untrained individuals as the intensity, frequency, and duration of strength training increases.[1] Protein supplementation increases muscle strength and size during prolonged strength training in healthy adults.[2] Increasing age reduces this effect; training experience increases this effect.[2] Protein intakes at amounts greater than about 1.6 g/kg/day do not further contribute to gains in fat free mass.[2]

The timing of administering the protein intake in reference to the training session has not been shown to change its outcomes, despite the widely held belief that pre- or post-workout supplementation is particularly effective.[3]


Whey protein supplementation seems to improve body weight, total fat mass, and some cardiovascular disease risk factors in overweight and obese patients.[4]
