Glucosamine Complete Glucosamine with Chondroitin, MSM & Quercetin plus Ginger & Rose Hip Extracts. This is a high strength glucosamine and chondroitin formula that also provides potent levels of other nutrients. Each ingredient has been selected based on their different, but complimentary, functions and are presented at levels that are nutritionally relevant. Three tablets provide the full 1400mg of glucosamine sulphate, the level used in many studies, as well as 330mg of chondroitin sulphate (see note below) and 150mg of MSM per daily dose. The powerful bioflavonoid quercetin has been included at a potent 50mg, plus 1200mg of ginger (as a concentrated extract), as well as 400mg of rose hip. Few, if any, joint formulas provide these potencies in a single formula.
