U-7 GASTRIC AID is a revolutionary dietary supplement for the gastric system. It is a palatable formula that helps horses suffering from poor appetite, poor attitude, poor performance, weight loss, or gastric distress. U-7 GASTRIC AID is a more effective and affordable alternative to antacids or drugs and provides longer lasting benefits in only 30 days. Other products add calcium, magnesium, and aluminum to neutralize stomach acids, which leads to the stomach producing more acid. U-7 GASTRIC AID contains NO calcium, magnesium, or aluminum and can really make a difference in the overall well-being of your horse.
