The Claim
There is a belief that collagen supplements can help make bones stronger by directly contributing to bone density, given that collagen is a key component of bone structure.
Origin
This belief is often rooted in marketing claims and simplified interpretations of the role of collagen in the body, sometimes reinforced by older studies focusing on bone health.
What Science Says
Emerging research, including randomized controlled trials (RCTs), suggests that collagen may support bone health by increasing bone mineral density, particularly in postmenopausal women. However, these findings are preliminary and more extensive, long-term studies are needed to confirm these effects.
Verdict
Mostly True
