Expert Answer
Hydrolyzed collagen vs collagen peptides: are they the same?
Quick Answer
In practice they're the same thing - both are collagen broken down for absorption, and the experts use the terms interchangeably. Huberman recommends 15-30g of hydrolyzed collagen daily paired with 500-1000mg vitamin C for skin. Just don't expect it to build muscle: it's a low-leucine protein and inferior to whey there.

on Collagen overall
What the Panel Says
Recommends 15-30g of hydrolyzed collagen daily with 500-1000mg vitamin C to support skin elasticity; notes it's inferior to whey for muscle due to low leucine.
Takes collagen peptides daily in his morning "Green Giant" drink and breakfast for skin and joint health.
Uses hydrolyzed collagen powder personally for its glycine and proline, which are important for collagen synthesis and wound healing.
Leans food-first and favors bone broth as whole-food collagen. Uses collagen peptides for gut and skin support.
Skeptical: calls collagen a low-quality protein with an imbalanced amino acid profile that shouldn't replace whey; sees a role as a glycine/proline source post-injury.
Detailed Answer
Are they the same thing
Yes. "Hydrolyzed collagen" and "collagen peptides" name the same powder. In both, enzymes have cut the collagen into smaller fragments your gut can absorb.
No expert on the panel spells the equivalence out. They just use the two labels for the same tub. Huberman says "hydrolyzed collagen." Patrick says "hydrolyzed collagen powder." Johnson says "collagen peptides."
How much, and with what
Huberman gives the clearest protocol. 15-30g of hydrolyzed collagen a day, paired with 500-1000mg of vitamin C. The figure he cites most is 15g.
The vitamin C is the point everyone lines up on. Your body cannot build collagen without it, and Patrick makes the same point about vitamin C in collagen synthesis. Patrick takes hydrolyzed collagen powder herself, for the glycine and proline. Johnson drinks collagen peptides every morning in his Green Giant. Hyman goes food-first and reaches for bone broth.
Will it build muscle
No. Attia is blunt about it. He calls collagen a low-quality protein with an imbalanced amino acid profile, and says it should not replace whey. He does see a use for it after an injury, as a source of glycine and proline. Even the experts who like collagen agree it loses to whey for muscle, because it is low in leucine.
Same product under two names. Take it with vitamin C for skin and connective tissue. Do not count it as your protein.

No. The experts agree collagen is inferior to whey for muscle because it's low in leucine, and Attia calls it a low-quality protein that shouldn't replace whey.
