Summary

This study tests whether taking collagen peptides daily for 6 months can help slow aging at the cellular level in adults aged 50-70 who are overweight and not very active. Researchers will measure telomere length (a marker of cellular age), inflammation, and body composition. 125 participants will be randomly assigned to take either collagen or a placebo, with blood tests and physical assessments at the start, 3 months, and 6 months.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: collagen peptides
What this could lead to: If it works, this could point toward a simple dietary supplement that supports healthier aging at the cellular level.
What could go wrong: This is an early-stage, small study (125 people) testing a supplement, not a drug. Results may show no effect on telomeres or aging markers, and any benefits may not apply to the general population.
