Gelnex hydrolyzed bovine collagen is a high quality collagen. Bovine collagen is a naturally occurring protein present in the connective tissue bones, cartilage and hides of cows. There are several types of collagen, each composed of different amino acids. The collagen from cows happens to be similar to the collagen we have in our own bodies and helps to maintain the health and structure of skin, bones, muscles, tendons and ligaments. Hydrolyzed collagen is simply collagen that has been broken down into smaller units of protein (collagen peptides). These smaller bits of protein make it that hydrolyzed collagen can easily dissolve in hot or cold liquids, which makes it ultra-convenient for adding to a morning coffee, smoothie or oatmeal.
