US - Alltech's organic selenium, Sel-Plex, recently received free choice allowance in livestock diets from the U.S. Food and Drug Administration (FDA).Sel-Plex is an organic form of selenium yeast, as it is presented in the same forms that are naturally present in plants. Organic selenium is more digestible than inorganic forms and better retained, which lets the animal build nutrient reserves against periods of increased demand without risking toxicity.
