- Low evidence3 studies
Across 3 randomized controlled trials, 2 reported beneficial moderate-sized effects on muscle strength, while 1 found a neutral small effect. Only 1 study reached statistical significance. Effects were typically observed after 12 weeks of supplementation. The studies primarily involved clinical populations (post-operative knee replacement patients and older adults with type 2 diabetes); one study used pea protein, not whey, in sedentary adults.
