More than four decades ago SOURCE President and Founder, Susan Domizi, was competing on her eventing horse, Hull, with hopes of being on the US Equestrian Olympic Team. "My horse Hull had hoof problems and couldn't maintain his body weight. He received the finest feeding program and veterinary care available. I suspected a nutrient deficiency and set out to find something to help him." When all the pieces were finally in place, SOURCEĀ® was formally introduced. Since 1975, SOURCE has been dedicated to maximizing the nutritional potential in seaweeds, the ocean's extraordinary herbs. Sustainably harvested from cold ocean waters, our ingredients undergo rigorous testing for herbicides and pesticides(negative), as well as microbiological and heavy metals testing. Our ingredients provide a unique and incomparable source of naturally occurring broad-spectrum micronutrients that are increasingly deficient in our foods and feeds, while the organically bound iodine and sodium alginates as well as other factors support detoxification. SOURCE micronutrients was the first nutritional supplement in the horse industry to ever offer a no-questions asked, no time limit, money back guarantee, despite warnings from everyone from bankers to competitors. Domizi so believed in customer satisfaction with her product, that she felt the guarantee would enable everyone to see the benefits of her micronutrients supplement totally risk free. From the single product, the original SOURCEĀ® micronutrients, first sold as a horse product, SOURCE, INC's seaweed-based micronutrient supplements are now marketed worldwide and include products specifically formulated for horses, dogs and people. SOURCE, INC. is a founding member of the NASC (National Animal Supplement Council), the non-profit industry group dedicated to protecting and enhancing the health of companion animals and horses throughout the U.S. We proudly display the Quality Seal showing our commitment to following the highest standard of quality control, 3rd part audits and labeling. http://nasc.cc
