Question 3

Is Rehmannia FDA approved?

Accepted Answer

Regulatory Classification

This ingredient is categorized as a dietary supplement, a designation that subjects it to the regulatory requirements of the Dietary Supplement Health and Education Act of 1994 (DSHEA). Under this law, the compound is not treated as a drug and therefore does not require clinical trials or Food and Drug Administration (FDA) approval for safety and effectiveness before it is sold to the public. Instead, the manufacturer is responsible for ensuring that the product is safe and that its labeling is truthful and not misleading.

New Dietary Ingredient Notification

If the substance is considered a New Dietary Ingredient—meaning it was not marketed in the United States as a supplement before October 15, 1994—the manufacturer must provide the FDA with a pre-market notification. This submission must include information that provides a reasonable expectation of safety for the ingredient under its intended conditions of use. The agency does not certify the safety of the ingredient upon receipt of this notification but maintains the authority to challenge the marketing of the product if safety concerns arise.

Market Oversight

The FDA maintains oversight of the supplement market through post-market surveillance and enforcement actions. It may identify ingredients that do not appear to be lawful for use in supplements and can take steps to remove products from the market if they are found to be adulterated or misbranded. While the ingredient is widely available, it must be produced in accordance with current Good Manufacturing Practices (cGMP) to ensure quality and prevent contamination.
