(Animed) Barrier Digestive Shield helps protect against possible contaminated feed and hay without limiting the absorption of nutrients. Provides your horse with state-of- the-art natural ingredients scientifically engineered to protect against possible unseen harmful contaminants and the uncontrolled variations in the quality of hay and grain fed to horses. BARRIER effectively neutralizes most mycotoxins, including aflatoxin and fumonisin that may be present in hay or grain. The functional carbohydrate in BARRIER binds harmful bacteria so they cannot attach to the gut walls. BARRIER prevents mycotoxins and harmful bacteria from being absorbed into the blood stream. Contains 7000 mg mannanoligosaccharides, 7000 mg mycotoxin absorbent, and 550 mg vitamin C. Feed 1/2 oz. per day; 2 oz. per day in times of stress. Powder.
