Chondroitin vs. Collagen: Joint Supplements Compared

Chondroitin is a large molecule that acts like a sponge, drawing fluid and nutrients into the cartilage while blocking the enzymes that break cartilage down. Collagen provides the direct amino acid building blocks required to synthesize new cartilage from scratch.

Chondroitin sulfate is a complex carbohydrate that gives cartilage its resistance to compression. It acts defensively by inhibiting matrix metalloproteinases (enzymes that destroy cartilage). Collagen acts offensively; it provides a high concentration of glycine, proline, and hydroxyproline, which are directly utilized by the body to build new Type II collagen fibers in the joint.

Chondroitin is an excellent protector, but because it is a very large molecule, its absorption rate is notoriously low (often under 15%). Hydrolyzed Collagen Peptides, however, have near 100% absorption, making Collagen far more efficient for noticeable structural repair.
