Have given our pony, Bullseye, Brewers Yeast for a few years, on the suggestion of our vet, following a quite bad case of laminitis. It was not described as a cure but as an aid to healing by assisting in the general well being of our pony with the benefit of keeping his digestion in good order due to the probiotic action of the yeast and the vitamins helping to keep his coat & skin healthy. We firmly believe that supplements are a valuable aid in equine health and find it so convenient that we can purchase all our supplements from one supplier - GLOBAL HERBS !
