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.
Quick Protocol
Dosage
5-30g daily for skin health (Huberman). ~15g daily is the most commonly cited dose for skin elasticity. Johnson takes collagen peptides daily as part of his morning drink and breakfast. No specific dosage from other experts.
Form
Hydrolyzed collagen peptides (powder) for supplementation — better absorption than intact collagen. Bone broth as a whole-food source (Hyman). Patrick uses hydrolyzed collagen powder in smoothies. Johnson uses collagen peptides in his Green Giant drink.
Timing
Morning with meals is most common. Johnson takes it in his morning drink. Patrick adds it to her smoothie. Consistent daily intake is more important than specific timing.
Key Findings
- Collagen is a structural protein essential for skin, cartilage, bone, tendons, and ligaments — it is the most abundant protein in the human body.
- Huberman recommends 15g collagen daily for skin elasticity, with a range of 5-30g/day for addressing skin thinning. He considers collagen superior to whey for skin but inferior for muscle.
- Attia's dedicated clip with Dr. Luc van Loon concludes that collagen does not significantly increase connective tissue protein synthesis compared to dairy protein — he calls it a 'low-quality protein' due to its imbalanced amino acid profile.
- Johnson includes collagen peptides daily in both his morning drink and breakfast, and has explored external collagen stimulation through Sculptra, radiofrequency devices, and hyperbaric oxygen therapy.
