SOURCE Micronutrients Original Dry Meal Formula The expanding depletion of our agricultural soils means that even today's finest feed ingredients are increasingly micronutrient deficient. The oceans are nature's richest storehouse of micronutrients. Certain marine plants, unlike plants grown on our agricultural soils, contain the broadest spectrum of trace minerals and other bioactive micronutrients of any plants on earth. SOURCE Micronutrients are totally natural and derived and concentrated from careful selection of these extraordinary marine plants. Our unique harvesting and processing is dedicated to preserving the maximum bioactivity of these natural materials. Every component undergoes extensive independent laboratory testing to ensure the dependable quality of the micronutrients that horsemen throughout the world have come to rely on since 1975. SOURCE contains no fillers, binders, preservatives, artificial flavorings, or colorings or added chemicals of any kind.
