Catalase 15,000 -Rise-N-Shine Simply Catalase" Antioxidant Enzyme is now available in ONE potent easy to swallow capsule, with 15,000 IU'S OF CATALASE in ONE CAPSULE! This makes our product one of the most POWERFUL and POTENT CATALASE ANTIOXIDANT ENZYMES on the market! 30 Day Supply Catalase 15,000 is a vitamin supplement that contains 15,000 units of the enzyme Catalase so that your body can replenish the Catalase Enzyme, which slowly depletes as we age. Hydrogen peroxide is naturally produced by the body, so when catalase levels decline, the hydrogen peroxide can no longer be broken down - which ages hair from the inside out. This results in weaker, aging hair, but our product has utilized modern science to provide the fix from the inside out! The magic of Catalase is that it catalyzes the decomposition of this aging compound to water and oxygen itself, therefore promoting healthy hair growth and long, strong beautiful hair. Catalase is a naturally occurring antioxidant enzyme present in the liver, red blood cells, and alveolar epithelial cells — the cells that line the insides of the alveoli in the lungs.
