I have been giving all my horses Omega Horseshine for several years. I am very fussy about what they eat especially their hay, but generally speaking, am not a big proponent of supplemental feeds. In fact, I think a lot of other people overdo that. However, I would never forego Horseshine. As far as I am concerned it is an essential part of my horses’ diet. They all have lustrous coats and get compliments all the time.
