Collagen is the most abundant protein in the body. It is a constituent of connective tissues and a key structural component of the musculoskeletal system, which is essential for mobility. Supplementing with collagen has been shown to help support metabolic turnover for the maintenance of healthy tendons, ligaments, skin, nails, and hair.RIVALUS COLLAGEN PEPTIDES are made from the hides of grass-fed, pasture raised cows. Using a precise extraction and hydrolysis process, collagen peptides are isolated to yield a purified powder that is highly soluble and nearly tasteless. Add 1-2 scoops of COLLAGEN PEPTIDES to any hot or cold beverage, shake, or liquid to complement your diet - without any added fat, sugar, cholesterol, soy, lactose, gluten, caffeine, or fillers.
