Certa-Flx - Formerly known as Corta Flex CORTA-FLX Powder: Now with 50mg HA per serving! Clinically Proven Horse Journal Product of the Year Recommended by Leading Veterinarians Worldwide CORTA-FLX is the first of its kind featuring the pure, micro-sized, water soluble, isolated nutrients comparable to the active ingredients found in Chondroitin, Glucosamine, MSM and Hyaluronic Acid. The effectiveness of any oral supplement is determined by its ability to pass through cellular walls and arrive at their intended destination. CORTA-FLX’s smaller molecules mean maximum assimilation and better utilization. In 1999, the Horse Journal stated CORTA-FLX produced dramatic results in 3 days and named it the Product of the Year. In 2002, Michigan State University researcher Dr. Hilary Clayton proved in a double-blind, placebo controlled study that CORTA-FLX dramatically reduced asymmetry in gate analysis testing on horses with degenerative joint disease. CORTA-FLX Powder has a tasty alfalfa base that mixes well with sweet feed and don’t all horses love alfalfa? CORTA-FLX Powder makes preparation of daily supplement baggies very easy.
