Collagen is essentially the glue of the human body. It’s contained in the middle layer of our skin and is responsible for how our skin looks and feels. It’s also in our muscles, joints, hair and skin. One of the main concerns with collagen has been that it isn’t easily absorbed by the body. But Physician’s Choice uses DigeSEB, which are clinically proven digestive enzymes, to help ensure that your body can readily absorb and get the collagen to where it needs to go.
