WORLD-CLASS STANDARDS

Proven by testing, testing, and more testing

A dedicated team of 75 quality experts tests every raw material we receive. Then they test the formulas throughout manufacturing, and finally, the product before it goes to you.

Product testing



  • In-Process

    Performs end-to-end testing every few minutes throughout manufacturing.

  • Analytical

    Ensures the product is free from harmful levels of contaminants and flawlessly formulated to perform as claimed.

  • Microbiology

    Verifies products are pathogen free and that all materials meet quality standards.

  • Physical

    Tests flavor, appearance, and sensory qualities for the customer experience.

  • Stability

    Proves products will perform effectively through the expiration date.

Gold-standard ingredients

Ginkgo leaves

One example of sourcing excellence is in your Ginkgo biloba products. The chemical constituents of the ginkgo leaf extract must be consistent across each batch to ensure its potency in the formula. But nature doesn’t supply the same rain, sun, and soil content every year. So, our parent company established our own ginkgo farms in France, China, and the United States.
By combining agrichemical-free leaves from three climates, we can adapt their ratios and ensure the same chemical quality in every batch. 

Getting the best raw materials

Our suppliers undergo an exceptionally rigorous qualification process. If they make it past our 19-page application—covering everything from allergens to how the ingredients are produced—vendors must then disclose their safety documentation, facility audits, source verification, and processes. If they pass the second stage (many don’t), the real work begins. We quarantine their materials at our labs for a battery of tests and qualifications to determine if they meet our elevated standards.
