Up to 90% of the collagen in our bodies consists of Type I as in our Pure Marine Collagen and 100% Hydrolysed Pure Collagen powders. It provides structure to skin, bones, tendons, fibrous cartilage, connective tissue and teeth. Collagen's amino acids can play a crucial role in our digestive system. Bone Broth helps to boost collagen levels to benefit growth of skin, hair and nails, and joint mobility.
