Free radicals are constant nags for our eyes and whole bodies. Luckily our bodies have a native defense system that works to oppose them, including a powerful enzyme known as catalase. Catalase works at lightning speeds and is very efficient; it is able to convert and neutralize thousands of free radicals at a time. Yes, our bodies make these enzymes, but a with more threats than ever from screens and airborne toxins, our delicate eyes can benefit from enhanced support. Our natural catalase enzyme comes from a SuperPure extraction of fermented beans.
