Summary

Protein powders are concentrated sources of dietary protein used to help people reach daily protein targets for muscle gain, recovery, or weight management. Whey, casein, and plant proteins differ in digestion rate and amino acid profiles, but all can support muscle protein synthesis when total intake is adequate. They are best viewed as a convenient food rather than a magic supplement.
