Relyne GI is a carefully formulated blend of gut-friendly hyaluronan and wellness-boosting beta glucan aimed at providing a natural, long-term alternative to support gastric health in horses. It does not alter gastric pH like PPIs and H2 blockers, and therefore does not interfere with digestion and/or nutrient absorption. Relyne GI aids in promoting gastric well-being in horses that may not respond to traditional therapies, as well as in equine athletes in training, travel and competition. Relyne GI has been thoroughly tested for banned substances, and is Clean Sport certified.
