A straight look at what human studies suggest — without overstated claims.
Does Collagen Support Joint Health? What Human Studies Show
Joint discomfort and stiffness are common as men age or place repeated stress on their bodies through training, sport, or physically demanding work. Over time, cartilage, tendons, and connective tissues are exposed to constant loading, which can affect comfort and mobility.
As a result, collagen supplementation has gained increasing attention as a potential way to support joint structure and long-term function. Rather than relying on marketing claims, it’s worth looking at what human research actually shows.
Why Joints Become a Limiting Factor
Joints rely heavily on collagen-rich tissues such as cartilage, ligaments, and tendons to absorb force and allow smooth movement. With age and repeated mechanical stress, collagen turnover can slow, while cumulative strain increases.
What Collagen Is — and What It Isn’t
Collagen is a structural protein found throughout the body and is especially abundant in connective tissues. Unlike complete dietary proteins, collagen is rich in specific amino acids such as glycine, proline, and hydroxyproline.
It’s important to be clear: collagen is not a complete, muscle-building protein. Its potential role lies in supporting the tissues that help joints tolerate repeated stress.
Evidence from Human Studies
A meta-analysis examined multiple randomised controlled trials (RCTs) investigating oral collagen supplementation in people with knee osteoarthritis. The analysis reported associations with reduced pain and improved function scores compared with placebo.
Study designs and collagen types varied, so this should be read as supportive evidence rather than a guaranteed outcome for everyone.

The Role of Vitamin C
Vitamin C contributes to normal collagen formation for the normal function of cartilage and bones, which is why it is commonly paired with collagen in evidence-led formulations.
How This Relates to Revayo Prime
Revayo Prime is formulated with hydrolysed collagen and Vitamin C. As with any supplement, results vary — it’s designed to support a consistent routine for men who stay active and want to prioritise joint comfort over time.
