Glucosamine, chondroitin, and collagen are well-known ingredients to improve knee joint damage, but proteoglycans have proven to be innovative alternatives.
The main component of articular cartilage is proteoglycan.
The ingredients of proteoglycan are glucosamine, chondroitin, and collagen. Even if you take glucosamine, chondroitin, and collagen, you have to synthesize proteoglycan in your body, and not all of them change to proteoglycan.
Therefore, proteoglycans are more effective than glucosamine, chondroitin, and collagen.
The market for glucosamine and chondroitin will replace proteoglycans in the future.
