Planet Paleo's Pure Collagen is 100% pasture raised bovine collagen powder. Collagen is a unique protein that is a rich source of the amino acids glycine and proline, which are commonly low in most protein sources. It is one of the most abundant proteins in the body, making up the skin, joints, bones, blood vessels and lining of the digestive tract. Directions: Take 1/1.5 scoops once or twice a day with or between meals. Mix with at least 200ml of water or juice. Can be used in warm drinks such as coffee or ginger tea.
