Collagen
Structural protein that supports skin elasticity, hair strength, and joint health.
How it works
Mechanism of Action
Collagen peptides are absorbed and stimulate fibroblasts to produce new collagen, improving skin hydration and elasticity.
Evidence-based uses
What Collagen Is Used For
Type I and III collagen peptides are best for skin. Hydrolysed for absorption.
Clinical Evidence
Oral collagen peptide supplementation significantly improved skin elasticity after 8 weeks compared to placebo.
Oral collagen peptide supplementation (2.5-10g/day) significantly increased skin elasticity, hydration, and dermal collagen density within 4-12 weeks across multiple RCTs.
Marine collagen peptides may be most effective for hair.
Clinical Evidence
RCT found 2.5g/day collagen peptides for 12 weeks increased hair thickness by 12% and improved self-rated hair volume compared to placebo.
Safety
Interactions & Warnings
Collagen peptides contain small amounts of calcium and other minerals. Taking with high-dose calcium may contribute to excess calcium intake in some individuals.
