Collagen Peptides: Joint and Tissue Support in Context
An evidence-focused overview of collagen supplementation, including realistic expectations and appropriate dosing.
Clinical Rationale
Collagen provides structural proteins for connective tissue. Supplementation aims to supply amino acids such as glycine and proline to support tendon and joint health, particularly in individuals with high mechanical load.
Evidence Snapshot
- Joint Comfort: Some trials show modest improvements in pain and function, particularly in active adults.
- Tendon Support: Preliminary data suggest potential benefit when paired with loading exercise.
Dosing Guidance
Common protocols use 10–15 g daily. Co-ingestion with vitamin C is often recommended to support collagen synthesis, though direct evidence is limited.
Safety
Collagen is generally well tolerated. Individuals with allergies to bovine, marine, or poultry sources should select products accordingly.
Bottom Line
Collagen peptides may support joint comfort and connective tissue adaptation, but benefits are typically modest and best paired with structured training.
