Dietary supplements can be thought of as supplemental alternatives for essentially healthy people, enabling them to live better and healthier. Dietary supplements are regulated like foods and must conform to quality and labeling standards. The approved ingredients in supplements are either those in circulation pre-1994 or those that have gone through a pre-notification process with the FDA. Examples of supplements indicated by the FDA are calcium for bone health and dietary fiber for regularity. Like medical foods, supplements can be useful nonprescription alternatives that provide affordability and retail access.
