Ensuring high-quality dietary supplements with 'quality-by-design'

Summary:
If applied to the $5-billion-per-year dietary supplement industry, "quality by design" -- a mindset that helped revolutionize the manufacture of cars and hundreds of other products -- could ease concerns about the safety and integrity of the herbal products used by 80 percent of the world's population.

If applied to the $5-billion-per-year dietary supplement industry, "quality by design" (QbD) -- a mindset that helped revolutionize the manufacture of cars and hundreds of other products -- could ease concerns about the safety and integrity of the herbal products used by 80 percent of the world's population.

That's the conclusion of an article in ACS' Journal of Natural Products.

Ikhlas Khan and Troy Smillie explain that the U.S. Food and Drug Administration (FDA) regulates dietary supplements as a category of foods, rather than drugs. Manufacturers are responsible for the safety of their products. However, they need not obtain FDA approval to market supplements that contain ingredients generally regarded as safe. While manufacturers, packagers and distributors are required to follow good manufacturing practices, variations in growing, processing and even naming the plants used to make supplements opens the door to problems and introduces challenges with reproducibility. As a result, "the consumer must take it on faith that the supplement they are ingesting is an accurate representation of what is listed on the label, and that it contains the purportedly 'active' constituents they seek," Khan and Smillie note. The authors looked for solutions in a review of more than 100 studies on the topic.

They concluded that a QbD approach -- ensuring the quality of a product from its very inception -- is the best strategy. One key step in applying QbD to dietary supplements, for instance, would involve verifying the identities of the raw materials -- the plants -- used to make supplements. "It is clear that only a systematic designed approach can provide the required solution for complete botanical characterization, authentication and safety evaluation," they say.
