What is Muscle protein synthesis?

Muscle protein synthesis, or MPS, is how your body makes new muscle protein. Your muscles are constantly being broken down and rebuilt. Over time, if building outweighs breakdown, muscle can grow. It is one of the main reasons rest, sleep and food matter as much as the workout itself.

Strength training and eating enough protein both raise MPS for many hours afterwards. For example, a meal with eggs, paneer, dal or whey after a workout supplies the amino acids your body uses. Spreading protein across the day is a common habit. Needs vary, so people with kidney or other health conditions should ask a doctor.
