Research suggests some improvement in pain and function for people with osteoarthritis; evidence for preventing or treating skin aging is disputed and depends in part on study funding. These findings do not establish that every product works or that supplements replace medical care.
What the evidence says
Evidence is outcome-specific. A 2024 trial sequential meta-analysis included 35 randomized controlled trials (RCTs) with 3,165 patients; its primary-outcome analysis used 25 trials with 2,856 patients. It found small-to-moderate improvements in osteoarthritis pain and function, without increased withdrawals or adverse events versus control. The authors wrote, “Strong evidence supports the efficacy and safety of collagen derivatives for osteoarthritis treatment” (Liang et al., 2024).
A 2025 review of knee osteoarthritis included 11 RCTs and 870 participants and also reported improved pain and function. However, results varied considerably across studies, so pooled results should not be taken as a guarantee of an individual benefit (review authors, 2025).
Skin-aging claims are less convincing. In a 2025 systematic review, studies without pharmaceutical-company funding showed no effect on skin hydration, elasticity, or wrinkles. The authors concluded, “There is currently no clinical evidence to support the use of collagen supplements to prevent or treat skin aging” (Myung et al., 2025).

Evidence at a glance
| Outcome | Research finding | Important qualification |
|---|---|---|
| Osteoarthritis pain and function | A 2024 meta-analysis found small-to-moderate improvements; a 2025 knee osteoarthritis review also reported improvements. | The studies concern people with osteoarthritis, not necessarily healthy people or every product. The 2025 review reported high variation among study results. |
| Skin hydration, elasticity, and wrinkles | A 2025 review found no effect in studies without pharmaceutical-company funding. | Findings differed by funding subgroup; the review authors said clinical evidence did not support supplements to prevent or treat skin aging. |
| Safety in osteoarthritis trials | The 2024 analysis found no increased withdrawal or adverse-event risk versus control. | This does not establish the safety of every formulation or replace individual medical advice. |
What to know before considering a supplement
The reviewed evidence does not establish a superior brand, a universally effective dose, or that a particular formulation delivers the reported effects. “Collagen peptides powder” is a product-search phrase, not proof that one brand or product is clinically validated.
In the United States, the FDA does not approve dietary supplements for safety and effectiveness before they are marketed. Manufacturers are responsible for product safety and truthful, substantiated claims, while FDA oversight is generally postmarket. The FDA advises consumers to consult a doctor, pharmacist, or other healthcare professional before deciding to use a supplement (U.S. FDA).
