Biomane most likely carries Biotine as a main ingredient, every horse is different but Biotine is a great ingredient for hair and coat growth and it is healthy. My mare is on a greenline supplement that is Biotine and Zinc, probably one of the best supplements I put her on! Her tail was from her hock in December now it’s down to her fetlock! I highly recommend Biotine supplements. But I’m not positive on what’s in Biomane!
