Collagen's amino acid profile is not ideal for muscle protein synthesis but is beneficial for skin and soft tissues.

“The amino acid profile is not terrific, from the perspective of muscle protein synthesis. Low in leucine and other branch chain amino acids, higher in other amino acids.”

“So collagen is not necessarily the protein you want to take if you want to build muscle. Got But it does have the precursors to make collagen and potentially the signaling molecules and the deptides.”

“why would it work or why would it have an effect because the suggestion is and that's the story behind it there's actually two stories one is that collagen has a lot of glycine and Proline and of course collagen is composed in your body also a lot of glycine and Proline and maybe does not a love of those amino acids in our uh in our Foods in our nutrition but of course um it doesn't matter that it actually increases muscle protein synthesis”
