The Claim
Many people believe that taking chondroitin supplements can fully cure osteoarthritis. This belief stems from claims that chondroitin rebuilds cartilage and eliminates joint pain entirely.
Origin
The myth largely originates from marketing materials and anecdotal reports that overstate the benefits of chondroitin for joint health.
What Science Says
Meta-analyses and randomized controlled trials (RCTs) suggest that chondroitin can provide modest pain relief and improve joint function, but it does not cure osteoarthritis. The effect sizes are generally small and vary between studies. Chondroitin may be more effective when combined with glucosamine.
Verdict
False
