With respect to adding substances to foods, the Federal Food, Drug, and Cosmetic Act sets out requirements for the certification of ingredients as Generally Recognized As Safe (GRAS). Under law, any substance purposefully added to food is considered a food additive that must be reviewed and approved by the FDA before being marketed. However, a significant exception exists for substances that have received GRAS certification because qualified experts have recognized it as safe under the conditions of expected use or the substance is excepted from the definition of a food additive. The FDA has established good manufacturing practices (GMPs) that companies must follow, as a way to ensure the identity, purity, strength and composition of their dietary supplements. These practices are the greatest measure currently in place to ensure the safety and legitimacy of these dietary supplements.
Generally, the FDA has authority over both finished dietary supplements and dietary ingredients under the Dietary Supplement Health and Education Act of 1994 (DSHEA), which prohibits supplement makers and distributors from marketing adulterated or misbranded products. The FDA does not examine or approve dietary supplement products before they are sold; therefore, it is critical that serious health-related illnesses or reactions be reported to the FDA by customers and health professionals. The duty to report adverse incidents related to dietary supplements is mandated by the Dietary Supplement and Nonprescription Drug Consumer Protection Act, passed in 2006.
The Dietary Supplement and Nonprescription Drug Consumer Protection Act requires Adverse Event Reporting (AER), under which manufacturers and distributors of dietary supplements are required to report, within 15 business days after being made aware of the event, serious medical problems that occur as a result of their products. Only an event described as a "serious adverse event" must be reported, the definition of which includes: "death," "a life-threatening experience," "inpatient hospitalization," "a persistent or significant disability or incapacity" or "a congenial anomaly or birth defect." An incident that "requires, based on reasonable medical judgment, a medical or surgical intervention to prevent an outcome described" must also be reported. Any new medical information learned by a firm must be provided within a year of the first report.
The reports must be kept for six years and made available for inspection by regulators. The FDA analyzes the records during inspections of a supplement facility, checks for compliance with current good manufacturing practices, determines whether the business has submitted all required reports, evaluates any processes in place for reporting serious adverse events, and reviews labels for completeness. Labels must include a domestic contact information for users to report adverse reactions to the supplement. Submission of an adverse event report may not be construed as an admission that the supplement product caused the event.
