A dietary supplement is a product that contains a “dietary ingredient” intended to supplement the human diet. Dietary ingredients include: vitamins; minerals; herbs or other botanicals; amino acids; and other substances such as enzymes, extracts, or concentrates. Dietary supplements, including probiotics, which contain potentially beneficial bacteria or yeasts, may be found in many forms such as tablets, capsules, soft gels, gel caps, liquids, or powders.
