The feeding of grain and concentrates to horses creates many problems because equine stomachs are designed for a grass based diet. Acid-X can transform digestion to enable horses to take in such food much more safely and comfortably. All horses on high grain diets should use Acid-X at a maintenance level. It has been shown recently that around 90% of racehorses and 70% of competition horses on grain based rations have stomach discomfort to some degree and are in need of nutrients such as those used in Acid-X.  Directions: To start use two blue 25ml scoops twice daily. Use at this level fot two months and continuously if required.
