Nutritional & Dietary Supplements

The U.S. Pharmacopeia defines nutritional and dietary supplements as chemically synthesized vitamins consisting of plant extracts and animal byproducts. These ingredients are not typically sterile, and when added into consumable goods, pose a threat if not regulated. Ingredients include cellulose, lactose, and starch, all of which carry and facilitating the growth of harmful microorganisms.

Supplemental products are threatened during varying stages of production including cultivating, harvesting, processing, packaging, and distribution. All of these processes need to be regulated to ensure that the final nutritional and dietary supplements do not pose a threat to the health and well-being of consumers.

The U.S. Pharmacopeia developed a set of standards to regulate the pathogenic presence in nutritional and dietary supplements. Testing for nutritional and dietary supplements include:

  • Total Plate Count
  • Coliforms
  • Fecal Coliforms
  • Total E. coli
  • Yeast and Mold Count
  • Staphylococcus
  • Salmonella
  • Pseudomonas
  • USP 2021
  • USP 2022
  • Aerobic Plate Count
