The FDA issued its updated draft guidance on new dietary ingredients (NDIs), which the agency said is intended to assist industry in deciding when a premarket safety notification for a dietary supplement containing a NDI is necessary. The guidance is also designed to help industry prepare NDI notifications.
The draft guidance is laid-out in a Q&A format and explains the definition of an NDI, when an NDI notification is necessary, the procedures for submitting a NDI notification, the types of data and information that FDA recommends manufacturers and distributors consider when they evaluate the safety of a dietary supplement containing a NDI, and what should be included in a NDI notification. In addition, the guidance contains questions and answers about parts of the dietary supplement definition that can affect whether a particular substance may be marketed as a dietary ingredient in a dietary supplement.
