Another evidence of the failure of BCCA. This study shows that after 2 hours of consumption, both BCAA and milk protein also increase muscle protein synthesis.
However, only milk protein maintained a high level of muscle protein synthesis within 5 hours.
When using BCAA, the protein synthesis value will return to the basic line.
In short: focus on eating complete protein; from the perspective of muscle exercise, the intake of individual amino acids is always poor.
