What Are Dietary Supplement GMPs?

GMPs are regulatory standards enforced by the U.S. Food and Drug Administration (FDA) that govern the manufacturing, packaging, labeling, and holding of dietary supplements. These practices ensure that supplements are consistently produced and controlled according to quality standards.

Key Elements of Dietary Supplement GMP (21 CFR 111):

  • Personnel and training requirements

  • Physical plant and facility design

  • Equipment and utensil control

  • Production and process controls

  • Component, packaging, and labeling controls

  • Holding and distribution procedures

  • Recordkeeping and documentation

  • Product testing and identity verification

Why Dietary Supplement GMPs Matter

  • Protect consumer health

  • Ensure product consistency and identity

  • Maintain brand integrity

  • Meet regulatory requirements to avoid warning letters, recalls, or penalties

Noncompliance can result in serious consequences, including FDA inspections, 483 observations, product seizures, or facility shutdowns.

Implementing a GMP-Compliant Quality System

A robust Quality Management System (QMS) is central to GMP compliance. Core components include:

  • Standard Operating Procedures (SOPs)

  • Master Manufacturing Records (MMRs) and Batch Production Records (BPRs)

  • Corrective and Preventive Action (CAPA)

  • Internal audits and supplier qualification

Whether building from scratch or optimizing existing controls, a documented and well-maintained system is non-negotiable.
