Joints hold our bones together. Without them, we would be helpless to move about and function normally. Calcium is essential for maintaining strong bones. It also helps prevent osteoporosis or bone loss, which takes its toll when the bone around a joint begins to crack or deteriorate. Get plenty of calcium, and cut back on nicotine and caffeine, which are both believed to interfere with calcium absorption. Exercise at least three times a week to support healthy joints & bones (walking is excellent). Our best-selling, PN Triple Glucosamine/Chondroitin/MSM combination beats the competition in potency, convenience, and price. There is no longer any need to buy individual products because your favorite brand simply does contain enough of each ingredient per serving.
