A protein powder derived from cow's milk, typically containing a mix of casein and whey proteins, used as a dietary protein source.

Why it’s used

Taken to increase daily protein intake, often alongside resistance exercise, to support muscle repair and growth.

What the evidence is for

supporting muscle protein synthesis and lean mass gains alongside resistance training.

What the evidence says

A substantial body of research, including systematic reviews and meta-analyses, supports protein supplementation combined with resistance training for increases in muscle mass and strength, though effect sizes vary and plateau above certain intakes. Milk-derived proteins specifically (as opposed to other protein sources) show comparable effects in most trials.

Dose studied

1.6–2.2 g — grams of total daily protein per kilogram of body weight, per resistance-training meta-analyses.

Context

Meta-analyses of resistance-training studies have generally examined total daily protein intakes in the range of roughly 1.6 to 2.2 grams per kilogram of body weight, with diminishing additional benefit reported above this range.
