Nutritional supplement for endurance, immune system and cardiovascular health. DMG (N,N-Dimethylglycine) is an integral part of animal metabolism, and is naturally produced in the horse's body. DMG helps your horse use oxygen better at the cellular level, can reduce lactic acid buildup, shorten recovery time after strenuous exercise, and reduce cramping. DMG allows your animal to maintain peak performance for a longer period, and to return post-stress blood lactate levels to normal more quickly. Horses quiet down and appetites improve. Mares also have an almost 30% increase in oxygen requirements during pregnancy.
