Hydrolyzed collagen vs collagen peptides: are they the same?

Short version: "hydrolyzed collagen" and "collagen peptides" describe the same thing. Both are collagen that's been enzymatically broken down into smaller, more absorbable fragments. The experts don't define the equivalence in so many words, but they use the labels interchangeably — Huberman says "hydrolyzed collagen," Patrick says "hydrolyzed collagen powder," and Johnson says "collagen peptides," all referring to the same powdered supplement.

On how to use it, the clearest protocol comes from Huberman: 15-30g of hydrolyzed collagen daily (the most-cited figure is around 15g), paired with 500-1000mg of vitamin C. The vitamin C pairing is the strongest point of cross-expert agreement — Patrick likewise emphasizes vitamin C's role in collagen synthesis — because vitamin C is a required cofactor for building collagen. Patrick uses hydrolyzed collagen powder herself for its glycine and proline content, Johnson takes collagen peptides daily in his Green Giant drink, and Hyman leans food-first toward bone broth as a whole-food source.

The important caveat is what collagen *isn't* good for: muscle. Attia is openly skeptical, calling collagen a low-quality protein with an imbalanced amino acid profile that shouldn't replace higher-quality proteins like whey. Even the more enthusiastic experts agree it's inferior to whey for building muscle because it's low in leucine. So the honest framing is: hydrolyzed collagen and collagen peptides are the same product, they're a reasonable skin/connective-tissue supplement taken with vitamin C, and they are not a muscle-building protein.
