Chondroitin Sulfate
Helps cartilage retain water and resist compression — may slow cartilage loss and reduce osteoarthritis pain, especially with glucosamine.
Chondroitin sulfate is a naturally occurring component of cartilage that helps it retain water and resist compression. It's commonly used alongside glucosamine for osteoarthritis. Evidence is mixed but some studies show modest benefits for pain relief and potentially slowing cartilage loss. Often recommended as part of a comprehensive joint support protocol.

“Large-scale, methodologically sound trials indicate that the symptomatic benefit of chondroitin is minimal or nonexistent.”
Baden KER et al. • Nutrients (2025)
“Overall, the evidence suggests that glucosamine and chondroitin are generally effective and well-tolerated, particularly for managing osteoarthritis and joint pain.”
