What are the beneficial effects of collagen consumption in the treatment of skin and orthopedic diseases?

In one paragraph

Collagen Peptides, a review (Heliyon 2023, PMID 37064452) — collagen supplementation was found to decrease wrinkle formation, increase skin elasticity, hydration, and collagen content, density, and synthesis. No numeric effect size is reported for Collagen Peptides in the source abstract.

Plain-English summary written and published by Magellan Longevity · medical review by Gabriel Radu, DO (physiatrist, NPI 1376861765). We summarize what the paper reported — we did not run this study.

The takeaway

Collagen supplementation may improve skin elasticity and hydration, reduce wrinkles, and enhance bone and joint health.

The question

What are the beneficial effects of collagen consumption in the treatment of skin and orthopedic diseases?

What they tested

The study hypothesized that collagen supplementation would show beneficial effects on skin and orthopedic health.

How they did it

This study was a literature review, synthesizing existing scientific evidence on the effects of collagen consumption.

What they found

Collagen supplementation was found to decrease wrinkle formation, increase skin elasticity, hydration, and collagen content, density, and synthesis. For orthopedic health, it increased bone strength, density, and mass, improved joint stiffness/mobility and functionality, and reduced pain.

What it means

Collagen supplementation demonstrates potential benefits for both skin and orthopedic health, addressing aging-related damage and issues from physical activity.

Limitations

The abstract does not explicitly state any limitations of the review itself or the body of literature it synthesized.

Where the published abstract does not list limitations, we say so rather than inventing them. Read the full paper on PubMed before drawing conclusions.

“Collagen is one of the main components of the extracellular matrix of the dermis and articular cartilage and influences mechanical and tissue-formation properties.”— from the published abstract, Heliyon 2023

Collagen Peptides

Collagen production declines with age, contributing to skin laxity, joint wear and connective-tissue fragility. Randomised trials of oral collagen peptides report measurable improvements in skin elasticity and joint comfort, making collagen a connective-tissue-focused element of a longevity routine.
