Synergy
What is happening. Vitamin C supports synthesis and stabilization of the cartilage matrix that chondroitin sulfate is part of, so the two complement each other for joint and connective tissue support.
Mechanism. Vitamin C is a required cofactor for prolyl and lysyl hydroxylases in collagen synthesis and supports chondrocyte production of extracellular matrix proteoglycans, providing the structural framework into which chondroitin sulfate glycosaminoglycans are incorporated.
Recommendation. Reasonable to take together for joint support. Take with a meal and keep vitamin C at typical doses (around 200 to 500 mg daily) rather than very high doses.
