Collagen protein and bone broth contain amino acids that may support skin elasticity and appearance when ingested regularly at a level of 15 grams per day over two weeks or more. While they are not as effective as whey protein for muscle growth due to lower leucine content, they can be a valuable addition for improving skin health.
"Andrew Huberman highlights collagen protein and bone broth for their potential benefits in improving skin elasticity and appearance, based on studies showing positive effects from consistent ingestion. He differentiates them from whey protein, noting their different amino acid profiles and primary benefits."
