Collagen peptides
Collagen peptides is a supplement that is sold over the counter.
Also known as Hydrolyzed collagen, Collagen hydrolysate
Collagen peptides are collagen broken down into small pieces so they dissolve in drinks. People take them hoping to support skin elasticity, joints and connective tissue; the body digests them like other proteins.

Is Collagen peptides FDA-approved?
Sold without a prescription. Supplements are not reviewed by the FDA before sale, so third-party testing matters. Sold as a dietary supplement or food ingredient.
As of September 23, 2026.
Key takeaways
- Collagen peptides are a protein supplement made from animal collagen.
- Some trials report better skin elasticity and hydration after about three months, but many are industry-funded.
- A 2025 meta-analysis found no effect when it looked only at high-quality, independently funded trials.
- It is generally safe, but it does not replace a balanced diet with enough protein.
How does Collagen peptides work?
Collagen is the main structural protein in skin, tendons and bone. Collagen peptides are collagen broken into small pieces. When you swallow them, your body digests them into amino acids and short peptides, like other proteins.
The idea is that some of those small peptides may signal skin cells to make more collagen. Whether that happens meaningfully in people is still debated.
What does the evidence say about Collagen peptides?
Emerging evidenceMeta-analyses report small improvements in skin hydration and elasticity, but many trials are small and industry-funded; joint evidence is weaker.
What to expect
What trials and prescribing information measured over time. Everyone responds differently.
- About 3 months
Trials that reported skin changes typically measured them after about 90 days of use.
What do clinicians say about Collagen peptides?
Nutrition experts see collagen as safe but oversold. The best-controlled studies are less impressive than the marketing.
Harvard's Nutrition Source notes some randomized trials found better skin elasticity, but most research is industry-funded, and FDA does not review supplements before sale.
Harvard T.H. Chan School of Public Health: The Nutrition Source, collagenA 2025 meta-analysis of 23 trials in the American Journal of Medicine found that trials without industry funding and high-quality trials showed no effect on skin aging.
Collagen supplements and skin aging: meta-analysis (Am J Med 2025)An earlier 2021 meta-analysis of 19 trials reported improvements in wrinkles, elasticity and hydration after about 90 days.

- People on a protein-restricted diet, such as for kidney disease, without advice
Only a licensed clinician who knows your history can decide whether it is right for you.
What are the risks and side effects of Collagen peptides?

- Usually from cow, pig, fish or chicken sources, which matters for allergies and dietary choices.
- It is an incomplete protein and does not replace a balanced protein intake.
- Supplement quality varies; look for third-party testing.
What should you ask a clinician about Collagen peptides?
- Is my overall protein intake adequate for my goals?
- Would this help my specific joint or skin concern?
