BioStride - Trainer's Formula. Intensive support for the worst imaginable hoof problems. Use to improve cracking, crumbling or delaminating hooves. You've heard the expression "no hoof, no horse"? It means not only that poor quality hooves lead to eventual lameness, but that the condition of a horse's hooves are an indication of its overall health and nutritional state. BioStride Trainer's Formula is our most intensive therapy for hooves needing help. Each serving of BioStride - Trainer's Formula contains d-biotin (a B-vitamin vital to hoof health), DL-methionine and L-lysine (essential amino acide), plus minerals, calcium, phosphorus, zinc methionine complex, and proteinated manganese and copper to maximize bio-avilability. All of these nutrients are blended in a base of yeast culture, dried distillers grains and rice hulls, making BioStride - Trainer's Formula the most blanced product of its kind. You'll see results in just a few weeks, and dramatic improvements in just a few months.
