Collagen is the most abundant protein in our body. In fact, you can think of it as the glue that holds the body together. Our bodies produce collagen naturally, but this declines with age starting in your mid-20s. Isagenix Collagen Bone Broth provides 8 grams of collagen peptides and bone broth protein from grass-fed cows never treated with routine hormones or antibiotics to support healthy glowing skin with hydration and elasticity.
