Collagen's Role And The Theory Behind Supplements
- Collagen is a major structural protein that declines with age and supports skin, bone, tendon, and ligament integrity.
- Supplements aim to replace lost collagen or boost production but the biological pathway from oral collagen to tissue effect remains uncertain.
Possible Joint Benefits Are Unproven
- Some small studies suggest collagen may reduce osteoarthritis pain and improve cartilage, but the evidence is limited.
- Clinical relevance remains unclear without larger, rigorous trials.
Promising Studies But Weak Evidence
- Existing studies show possible improvements in skin firmness, hydration, and elasticity but have limitations like small size or mixed ingredients.
- Large, well-controlled randomized trials are still needed to prove that oral collagen alone causes these benefits.
