Collagen peptides and your joints: what the research says
Research on specific collagen peptides suggests they may support joint comfort. Here is what those studies can, and cannot, tell us.
If you like to stay active, your joints do a lot of work. Collagen is part of connective tissue, which changes as we age.
Studies have examined specific collagen formulations for joint comfort. Results from those formulations should not be assumed to apply to every product.
Hydrolyzed, low-molecular-weight collagen peptides are absorbed more readily. They supply the specific amino acids (glycine, proline, hydroxyproline) your body uses to build connective tissue. Researchers have detected some collagen-derived peptides in the bloodstream after ingestion, but absorption alone does not establish a joint benefit.
Studies in active adults suggest that consistent daily use of specific collagen peptides may support joint comfort and mobility over several months.
