I recently started back exercising daily on a bike and reformer Pilates machine , after a few years of only walking as exercise. I am combining the Mismo MSM , Pure Marine Collagen and Mismo Vitamin C as my recovery drink after my daily routine . My joints are much happier as I used to suffer from knee pain but I find a don’t anymore . I have noticed my nails are stronger and my skin is smoother. Very happy with the results
