Horses that have been off feed or sick, especially with diarrhea and other gastrointestinal conditions, may benefit from Biotin supplementation. Also, research has shown that feeding very high and expensive levels of Biotin (total intakes of 15 mg to 30 mg per day) for a year or more will improve hoof condition in some horses. Supplements can be purchased that are designed to furnish high levels of Biotin as well as certain other nutrients believed to be involved in hoof growth. Most horses will not need additional Bio
