The extra ingredients in Cosamin® ASU have been shown to work better than the combination of glucosamine and chondroitin alone.
Cosamin® ASU is designed for active people with joint discomfort. The makers of Cosamin DS have taken their #1 orthopedic surgeon and rheumatologist recommended joint product and added avocado/soybean unsaponifiables (ASU) to make a product that is more effective than the additive effects of all three ingredients. To this they have added the antioxidant green tea extract to help with joint and overall body defenses. Start out with 4 capsules per day until the desired effect is noticed, then gradually reduce to a maintenance dose.
