Consensus Report
Collagen
Strong Consensus
out of 5
Based on 26 videos (38 hours analyzed) across the experts · Updated 2026-03-21
Expert Positions
The Verdict
4 of 5 experts support collagen for skin and connective tissue health, but Attia is notably skeptical — citing research showing collagen does not outperform whey protein for connective tissue synthesis. Johnson is the strongest advocate, taking collagen peptides daily in his Blueprint protocol. Huberman recommends it specifically for skin, not muscle. All experts agree collagen is inferior to whey for muscle building.
Where They Disagree
Attia considers collagen a 'low-quality protein' that does not outperform dairy protein for connective tissue synthesis, while Huberman, Patrick, and Johnson actively recommend collagen supplementation for skin and connective tissue benefits.
Huberman's own guest (Dr. Soleymani) discusses 'limitations of collagen supplements,' suggesting the evidence is not universally accepted even among his show's experts.
