GMP Quality Seal Reaches Supplement Shelves
12 February 2001

Until recently, finding out if a supplement product is well made required the finely honed persistence of a private detective. You asked a company's Quality Assurance professionals a slew of highly technical questions about matters like microbial contamination, cleaning solutions, and personnel training. And you often got vague or evasive answers because such questions usually intrude into proprietary aspects of production.

But the good manufacturing practices (GMP) inspection program of the National Nutritional Foods Association (NNFA) -- a trade organization encompassing approximately 1000 producers as well as retailers -- is changing all that. Companies are being inspected by independent, third-party professionals who are getting answers to a long checklist of technical questions because this inspection program protects corporate privacy. As of January 2001, twenty companies have now completed NNFA's inspection and certification process and can use the GMP seal on their product labels and literature (see list below).

GMP inspection covers all aspects of production

Many quality issues are included in the audit, such as double checking the identify of raw materials to ensure one has the correct substance, testing for the presence of heavy metals or microbials or other contaminants, and use of stability studies to determine accurate expiration dates. The inspection covers the entire production process -- from receiving raw materials to shipping completed products out the door.

"This program will help establish credibility in the eyes of consumers," according to Jim Roza, QA Manager of Now Foods, whose company was inspected in July 2000. "The person who inspected us was a 40-year veteran of FDA inspections who is very experienced and has travelled all over the world doing this kind of work." Roza believes the NNFA's GMP program will dovetail nicely with the FDA's proposed GMP standard, which should be published early this year (2001).

GMP program features independent, third-party inspections

NNFA's inspection program requires that auditing companies must be independent, with no conflict of interest, for each company that they inspect. The inspectors are trained to conduct GMP audits according to a checklist and performance rating system developed by NNFA.

Companies that have passed the GMP audit

The following companies have passed NNFA's GMP inspection and certification process as of January 2001:

  • BIOSINT USA, Larchmont NY

  • Country Life, Hauppauge NY

GMP seal empowers consumers to make quality choices

Having a solid GMP program ensures that a manufacturer is producing consistent quality -- from batch to batch, lot to lot, bottle to bottle and tablet to tablet. Thus, labels with this seal allow consumers to buy with confidence, knowing that the product is well made.
