Collagen Peptides

Hydrolyzed collagen protein. Growing evidence for skin elasticity and hydration; early positive signals for joint comfort in active people.

What the science says

  • Improved skin elasticity and hydration Moderate evidence

    Randomized placebo-controlled trials show measurable improvements in skin elasticity and hydration after 8+ weeks of collagen peptides. Trials are often industry-funded, but results are consistent across studies.

  • Joint comfort in athletes Limited evidence

    A randomized trial in athletes with activity-related joint pain found modest pain reduction with 10 g/day of collagen hydrolysate. Evidence is promising but still thin.

Dosage & safety

Studied dose2.5–15 g/day of hydrolyzed collagen peptides; skin studies typically use 2.5–10 g/day for at least 8–12 weeks.
SafetyVery safe — it is essentially a protein. Not a complete protein (lacks tryptophan), so it doesn't replace dietary protein.
