| Lean Mass Casein protein supports lean mass gains with resistance training similar to whey; some evidence for better fat loss with casein. | Improves (the measure goes up) | Moderate effect | 150 people |
Supplement
Calcium caseinate is a milk protein, made by binding casein to calcium, that supplies amino acids the body uses to build and repair muscle. People mostly look at it for muscle size and strength, and the evidence is moderate: it stimulated muscle protein synthesis about as well as whey over 24 hours, and gains alongside resistance training were similar. Evidence for appetite is limited, with some studies finding it filled people up more than whey.

| Muscle Protein Synthesis Casein stimulates MPS comparably to whey over 24h despite lower acute peak. With resistance training, muscle gains are similar to whey protein. | Improves (the measure goes up) | Moderate effect | 200 people |

| Satiety Casein increases satiety more than whey in some studies due to slower gastric emptying and prolonged gut hormone release. | Improves (the measure goes up) | Small effect | 100 people |
