What type of collagen is used in My Daily Collagen?

My Daily Collagen™ contains a patented ingredient called Fortigel®, sourced from Types I and III grass-fed, pasture-raised bovine. Clinical studies show that the Bioactive Collagen Peptides® in Fortigel® accumulate in joint tissue over time and stimulates cell biosynthesis to produce collagen (which makes up the “scaffolding” of cartilage) and proteoglycans (which provide elasticity).
