Flexcerin™ is a scientifically designed formula, based on years of research and testing, which promotes healthy joint function and helps alleviate pain and swelling, and repair damaged joints. Flexcerin's™ Maximum Strength Bone and Joint Formula was formulated to help rebuild worn joints, lubricate stiff joints, increase range of motion, improves mobility and flexibility, soothe inflamed joints, and decrease pain associated with arthritis. Because joint pain is so debilitating, Glucosamine and Chondroitin alone are not enough.
