1-Month Supply PEREGRUNE engineers specifically for runners. Big supplement companies design mainstream vitamins for the masses because that is where there are the most people and sales. But runners are different. We are more active than everyday adults. We burn more calories and sweat away more nutrients. We work our muscles and joints harder. That's why Peregrune designs vitamins and supplements for the specific needs of runners. Product Benefits * TRI-JOINT COMPLEX FOR TOTAL KNEE JOINT HEALTH: Engineered for runners with Glucosamine, Chondroitin, and MSM for total joint, knee, and cartilage health. * 3X MSM TO RELIEVE STIFFNESS: Unlike most mainstream brands, our product contains 3X MSM (methylsulfonylsulfate) to lubricate runner's joints and mitigate joint stiffness --- a frequent ailment.
