This a double-strength formulation containing twice the active ingredients per capsule as the original regular strength. Formulated to deliver maximal cartilage support. Glucoasmine HCl stimulates cartilage production while Chondroitin Sulfate inhibits enzymes that break down cartilage. Cosamin® DS is the only brand proven effective in controlled, published U.S. studies to protect cartilage from breakdown and reduce joint pain. This new formulation reduces the number of capsules required daily for both initial and maintenance administration and is more cost effective.
