GMP (Good Manufacturing Practice) is an internationally recognized production standard that ensures controlled hygiene procedures, raw material traceability, and quality control at every stage of the manufacturing process.
In the European Union, manufacturing dietary supplements at GMP-certified facilities is mandatory. The standard covers the full scope of production: from the receipt and testing of raw materials to the packaging and storage of the finished product.
Is GMP mandatory in Europe?
Yes, manufacturing dietary supplements at GMP-certified facilities is mandatory in the European Union for all manufacturers.
How do I verify that a factory is genuinely GMP certified?
Ask to see the GMP certificate of the specific manufacturing facility — not just of the company proposing the partnership, since they are not always the same entity.
Does GMP differ from ISO?
Yes. GMP specifically focuses on pharmaceutical/supplement production processes, while ISO 9001/22000 are broader quality management and food safety standards. They often coexist.
