"I was trying to find a hoof supplement that had comparable amounts of biotin, methionine, lysine, zinc, and copper to that of Farrier's Formula - but was easier to obtain and not as hard on the wallet! Most of them seem to have too much or too little the vitamin/minerals in FF. I found Platform to be the closest in make-up and didn't involve buying it by 50 lb bags. So far my horse's hooves have had excellent growth and you can clearly see the difference."
