Biotin is considered to be one of the most important vitamins for hoof health and feeding supplemental biotin above the amounts normally found in feed is one way to improve hoof health. However, there is more to healthy hooves than just biotin. In addition to Lysine, Methionine and Zinc, Biotin Complete® also contains concentrated amounts of B Vitamins, amino acids and trace minerals to offer the most comprehensive and concentrated biotin formula ever produced. Biotin Complete does not contain sugars such as Dextrose or Maltodextrin to water down the formula and make it less effective. Since it takes time for new hooves to grow, it may take 10 to 12 months to completely replace the hoof with a new, stronger wall, with healthy growth appearing at the top of the hoof in as little as 2 to 3 weeks.
