Keratin is a protein found in the body of humans and animals that makes up the structure of the fingernails, hair, and skin. Usually, natural keratin from animal sources is insoluble and indigestible. KERAGEN-IV™, however, is a pure keratin protein that is gently extracted to make it fully bioactive and digestible.
KERAGEN-IV™ supports the body’s ability to make collagen IV and collagen VII.
Collagen IV and VII are only made in the human body and can’t be replaced by dietary collagen. These unique collagens are responsible for skin strength and elasticity.
