| Fat Mass Meta-analysis: no difference from whey (SMD 0.07, p=0.760); 10.8% fat loss in one 8-week study | Improves (the measure goes down) | Moderate effect | 270 people |
Supplement
Beef protein is a powder made from beef that supplies the amino acids muscles use to build and repair tissue. The evidence is moderate that people gained more lean mass and lower-body strength than with no extra protein, and results matched whey. One small study found muscle building was lower than with whey in the first two hours after exercise, though over five hours there was no difference.
