Provides the spectrum of B-Group Vitamins indicated for hard working horses engaged in racing and rigorous training/performance regimens being fed high grain rations. Improves energy metabolism to ensure the efficient release of energy necessary for optimal muscle function. Promotes red blood cell formation and regeneration. A less than optimal production of red blood cells may lead to a lowered oxygen carrying capacity of the blood, resulting in insufficient muscle perfusion. Ideal for hard working horses prone to sweating and electrolyte loss.
