Expert Answer
Does collagen actually help your skin?
Quick Answer
4 of 5 experts support collagen for skin, but Attia is skeptical — calling it a 'low-quality protein.' Huberman recommends 15g daily for skin elasticity. Johnson takes collagen peptides daily. All agree: it's not for muscle building.

on Collagen overall
What Researchers Say
Recommends 15g daily for skin elasticity. 5-30g/day for skin thinning. Pair with vitamin C.
Takes collagen peptides daily in morning drink and breakfast. HBOT increased his collagen fiber density.
Calls collagen 'low-quality protein' that does not outperform whey for connective tissue synthesis.
Uses hydrolyzed collagen powder in her smoothie. Highlights glycine and proline for wound healing.
Detailed Answer
Collagen for skin has moderate evidence. Huberman recommends approximately 15g daily (5-30g range for skin thinning), always paired with vitamin C for synthesis support. Johnson takes it daily and HBOT increased his collagen fiber density.
Attia is the notable skeptic — his analysis with Dr. Luc van Loon concludes collagen does not outperform dairy protein for connective tissue synthesis. He calls it a "low-quality protein."
The consensus: collagen may help skin (several RCTs show improvements in elasticity), but should never replace whey for muscle building. Always pair with vitamin C.
