Move Free Advanced Triple Strength Plus MSM & Vitamin D is 2x MORE EFFECTIVE at comforting sore joints than Glucosamine and Chondroitin alone (including double and triple strength). Its Triple Strength formula means you ONLY have to take just 2 tablets per day. Move Free Advanced Plus MSM & Vitamin D has the Advantage of 4 (Glucosamine, Chondroitin, Uniflex and Joint Fluid) PLUS the addition of MSM and Vitamin D. Vitamin D helps your overall bone health and joint movement in two significant ways: first, Vitamin D helps your bones absorb calcium better and second, it helps your bones retain the calcium already in them. This is very important because as we age our bones lose calcium. We also added MSM, which is an important part of joint cartilage that, when replenished, actually improves joint comfort. Uniflex is a ground-breaking dual bioflavonoid antioxidant system. By protecting joints from the radical antioxidants that accelerate the breakdown of cartilage and other joint tissues, it helps keep joints working better and feeling younger. Joint Fluid (Mega-Potent Hyaluronic Acid) helps to lubricate, rejuvenate and rehydrate joints. Clinical studies show that oral Hyaluronic Acid is absorbed in the joints. (A.G. Schauss et al, FASEB, 2004) Glucosamine and Chondroitin help by lubricating, cushioning, strengthening, protecting and rebuilding joints. Move Free Advanced Triple Strength Plus MSM & Vitamin D offers a powerful, fast-acting combination of all these nutrients. Better and faster results!
