SupplementSupplement: powders, drinks and capsules
- FDA status
- Sold as a dietary supplement. The FDA doesn't approve supplements before they are sold. FDA on supplements ↗
- In people so far
- A 2025 review of 23 randomized trials (1,474 people): overall, skin hydration, elasticity and wrinkles improved, but not in trials without industry funding or in the higher-quality trials. PubMed ↗
- Safety
- Supplements are not checked by the FDA for safety or effectiveness before they are sold. FDA on supplements ↗
- In sport
- Not on the World Anti-Doping Agency's 2026 Prohibited List. WADA ↗

The basics
What the research has found so far
- A review of studies found that hydrolyzed collagen beat placebo (a dummy pill) for skin hydration, elasticity and wrinkles.
- A review of studies found that trials not funded by drug companies showed no effect on skin hydration, elasticity or wrinkles.
- The same review concluded there is currently no clinical evidence to support collagen supplements for preventing or treating skin aging.
- A review of studies found that high-quality studies showed no significant effect in any category.

Questions to ask your doctor
- Is Collagen peptides a sensible option for me, given my health and the medicines I take?
- Could Collagen peptides interact with any medicine or supplement I already take?
- What side effects should I watch for, and when should I stop or call you?
- Supplements aren't checked by the FDA before sale. Is there a brand or a third-party test seal you would trust?
- How would we tell whether it is helping, and when should we review it?

Amounts, servings and prices are as each maker lists them on its own page, checked Oct 16, 2026. Price per serving is the price divided by the servings per container on the label; “—” means the page didn't say. A serving is the maker's serving size, not a recommendation.

What others are writing
Recent articles about Collagen peptides from health journalists, hospitals and universities. We link to them; we don't write or endorse them.
Collagen Peptides: Benefits and Side Effects ↗
“Collagen peptide supplements may support your skin, joints and bones — but there’s no guarantee”
A Cleveland Clinic dietitian explains that collagen peptides may support skin, joints and bones, but research is mixed and results are not guaranteed.
Do collagen supplements fulfill their promises? ↗
“Some scientific evidence suggests collagen supplements can help improve skin elasticity, strengthen hair and nails, reduce joint pain, and enhance bone density.”
The article says collagen supplements may have some benefits, but research is early and large-scale studies are needed to confirm them.
