 At Natural Factors we are committed to providing the highest quality products to our customers. All of our products undergo rigorous testing at all levels of the production process in accordance with United States Pharmacopeia (USP) guidelines. Our manufacturing is done according to Good Manufacturing Practices (GMP) guidelines laid out and regulated by the Health Protection Branch (HPB) of Health Canada. Factors Laboratories also follows Good Laboratory Practices (GLP) guidelines.
 Our quality control and quality assurance programs guarantee that our products are among the highest quality available on the market today and our new product development research now includes clinical trials on specific products to ensure their usefulness in enhancing people's health.
- High Performance Liquid Chromatography (HPLC) equipment identifies key active ingredients in products
- If no testing standards exist for a particular herb, Natural Factors Labs has the expertise and state-of-the-art facilities to develop objective testing methods.
- We test both finished products and raw materials for potency and identification, using chromatography (HPLC), spectroscopy (CP/AAS, UV/VIS) and titration
- Sample preparation involves powdering, weighing and extracting.
- Particulates are removed by centrifugation and filtration.
- Compounds are identified by using our HPLC Diode Array Detector (DAD) or by specific chemical tests. The DAD allows us to store an electronic library of standardized UV/VIS spectrum fingerprints for matching and qualifying our samples.
- We also test our raw materials for impurities, heavy metals, arsenic, chlorides and sulfates.
- Finished tablets and capsules are tested for weight variation, content uniformity, disintegration and dissolution
- Natural Factors has played a leadership role in developing its lines of "Standardized Potency" herbs that provide guaranteed levels of active ingredient.
