Nu-Hoof Maximizer is a scientifically formulated nutritional supplement with added biotin, folic acid, riboflavin, lysine, methionine, copper, iodine, and zinc. Nu-Hoof maximizer is based on research work in England and presented to the British Equine Veterinary Association in September of 1983(1). Swiss Researchers reported the results of a study conducted at the Spanish Riding School in Vienna, Austria (Linden, et al, 1993)(2). Both associations reported dramatic improvement in hoof integrity in as little as three to five months. The results at the Spanish Riding School in Vienna, Austria, demonstrated the beneficial effects of a biotin based supplement on hoof condition of Lipizzaner horses, by reducing the incidence and severity of horn defects, increasing tensile strength, and improving the condition of the white line. The study also emphasized supplementation for over 90 days to improve hoof growth. Significant improvement was shown in hoof horn hardness and thickness, and horses that were previously tender on their feet moved more freely and confidently. With continued supplementation for six to nine months, additional improvement resulted in stronger perioples, better horn surface, depth of heels and hoof shape, and easier shoeing with more and stronger hoof horn to work with. Some horses required up to one year of supplementation to obtain maximum benefit.
