Glucose is the most important energy source for horses during exercise. Low blood glucose levels are associated with fatigue and reduced performance, and maintaining blood glucose levels is especially important during prolonged exercise, when competing and for horses that are lacking in energy. This paste increases blood glucose levels in a controlled, safe and sustainable way whilst not excessively increasing blood insulin levels. It is rapidly absorbed, increases blood glucose levels within 30 minutes and can maintain an increased level for two hours. It can also be given after training or competition to aid recovery.
