Poor quality hooves can lead to eventual lameness and the condition of a horse's hooves are an indication of your horse's overall health and nutritional state. Each serving of Formula 707 hoof health contains D-biotin (a B-vitamin vital to hoof health), DL-methionine and L-lysine (essential amino acids), plus minerals calcium, phosphorus, zinc methionine complex and proteinated manganese and copper to maximize bio availability. All of these nutrients are blended in a base of yeast culture, dried distilled grains and rice hulls, making hoof health the most balanced product of its kind. You'll see results in just a few weeks and dramatic improvements in just a few months.
