I feed my horses BOSS for the first time starting last Feb. I liked how shiny it made their coats and how they started sheding earlier than usual. My farrier even notice improvement on their hoofs. But I have been hearing some concerns about giving horses BOSS. I am wondering what I can feed my horse that would give the same results as BOSS. I have thought about Flexseed but can't seem to find it around here, or I don't know where to look for it at. Any advice would be appreciated. My oldest horse is ten and the youngest is two. I don't know if that makes a difference but just in case. They seem very sound.
Thanks in advance
