Cytozyme-AD™ contains a unique proprietary complex of neonatal bovine tissue and porcine tissue concentrates to help support adrenal health and function.* Cytozyme-AD™ is a mild formula that does not contain adrenal herbs and nutrients that can sometimes cause overstimulation. It is designed to target the health of the hypothalamic pituitary adrenal (HPA axis), the body’s central stress response system. In addition, Cytozyme-AD™ contains superoxide dismutase (SOD) and catalase, both derived from vegetable cultures, to provide antioxidant support.
