Zesterra is a 100% all-natural supplement for horses. It’s formulated to provide support for horses that are prone to stress or experience ulcers or ulcer symptoms. Zesterra is a unique equine supplement that neutralizes excess gastric acid, encourages feed and water consumption and allows for greater nutrient absorption. It’s particularly helpful when your horse  experiences stressful situations like hauling, foaling, heavy training or extreme weather.  
Zesterra acts as a
Stress Reliever: The neutralization of excess acid in the stomach reduces the production of stress-elevating cortisol.
Improves Hydration
Appetite Booster: The increase of healthy gut flora and neutralization of acid helps boost appetite.
Ulcer Prevention: Reduction of stomach acid is key to ulcer prevention, and it also improves the rate of healing in horses that are being treated for this condition.
Facilitates Ideal Body Condition Score: With the improvement in digestion, nutrient absorption and appetite, horses (especially hard keepers) are able to gain or maintain a healthy weight.
Prevents Respiratory Infections: Giving a horse a dose of Zesterra can neutralize acid, which in turn reduces discomfort and cortisol release. This strengthens the immune system and can help prevent respiratory infection. It’s also beneficial to give the horse a dose before the onset of a major weather change or when there’s a disease outbreak.
Immune Booster: Zesterra can boost the immunity of horses, especially mares and foals during the last months of gestation and immediately after foaling.
