Plexus products are designed by industry and nutrition experts, including Ph.D. research scientists, who work in consultation with field leading health science researchers on our Scientific Advisory Board. Each ingredient is reviewed for safety and efficacy.
Plexus products are manufactured in cGMP and FDA inspected manufacturing plants, and we hold these plants accountable to our strict QA standards.
Each ingredient is tested for potency and purity to our standards before use. We test during manufacturing to ensure consistency, and we test at the end of manufacturing to ensure we meet label claims. This includes testing for heavy metals, which is routine for all Plexus products and raw materials prior to release, per federal regulations.
How are Plexus ingredients chosen and tested for quality?
Plexus product ingredients are specifically chosen for identity, potency, and purity from reputable suppliers that meet our internal quality and safety standards. Ingredients used in Plexus products are routinely tested for:
Physical Characteristics, which include visual, color, odor, taste, and density properties.
Identity, which consists of a chemical purity test or matching an ingredient in a pass/fail fashion to a particular species of botanical or herb.
Potency, which is the concentration of active or marker compounds.
Purity, which is the absence of impurities such as moisture, microorganisms, pathogens, heavy metals, residual solvents, pesticides, or mycotoxins.
Who does the Plexus Product Testing?
Plexus products are tested at microbiology and chemistry laboratories which are ISO 17025 accredited and adhere to AOAC, USP, Compendial, FDA and USDA standards. Additionally, Plexus performs audits on each lab to assure they meet our quality standards. As a final check on the laboratories, Plexus will confirm the data received by one laboratory by sending the sample to a separate laboratory for comparison.
