Our locomotor system consists of an active and a passive part. The passive part is made up of our skeletal system and joints. The movement of our body is made possible by the joints, an important element of which is the cartilage that protects the ends of the bones. Cartilage is a heavy-duty, flexible tissue, the flexibility of which is closely dependent on the water content of the intercellular material produced by cartilage cells. Glucosamine sulfate and chondroitin sulfate are water-binding natural components of cartilage tissue. Collagen is one of the natural components of skin tissue. The high-purity natural collagen in the product is made from Peptan® type 1 bovine collagen peptide, which is produced by the French company Rousselot, one of the world's leading collagen manufacturers. OptiMSM is the natural MSM produced by Bergstrom Nutrition in the USA with thirty years of experience. Vitamin C contributes to the reduction of tiredness and fatigue, to the normal formation of collagen and thereby to the maintenance of the normal condition of blood vessels, skin, teeth, gums, cartilage and bones. Vitamin D contributes to the maintenance of healthy bones and muscle function, as well as to the normal absorption/utilization of calcium and phosphorus. Vitamin K is involved in the maintenance of normal bones. Manganese, zinc and calcium contribute to the maintenance of normal bones. Calcium contributes to normal muscle function. Manganese contributes to normal connective tissue formation. Copper is involved in maintaining the normal state of connective tissues.
