NAF EnerG is an everyday supplement designed to support the energy demands of a working horse. Fortified with iron, vitamins and trace elements, this fast acting, veterinary approved liquid formula is designed to support the performance of the hardworking equine athlete. The sports horse demands more of his body to perform to his full potential. As his performance increases so too does his requirement for specific nutrients. It's well known that essential salts are lost through sweat. However, not only are electrolytes lost, so too is iron. Iron is vital for the health and performance of the sports horse.
