The last trimester of pregnancy is one of the most demanding stages for a broodmare and one of the most important periods for her foal’s development. Organnact Gest UP Horse Supplement was developed to support pregnant mares during late gestation, helping them stay nutritionally balanced, supported, and ready for foaling.

Gest UP provides targeted nutritional support during the phase when the foal experiences significant growth and the mare’s body faces increased nutritional demands. Its formula helps support feed efficiency, gut balance, immune response, antioxidant protection, and the mare’s natural preparation for high-quality first milk.

Designed especially for pregnant mares, Gest UP combines live yeast, yeast cell wall components, L-glutamine, and antioxidants to help support digestive function, intestinal integrity, immune system response, and overall wellness during this critical period.

With a convenient powder format and a pleasant green apple flavor, Gest UP is easy to add to the mare’s daily feeding routine. Each container provides 30 doses, making it a practical supplement for late gestation nutritional care.
