The Pure Process

Unwavering production standards and transparency mean sourcing the purest ingredients, rigorous testing for metals, toxins, contaminants, and allergens, and quality control processes that ensure sterile, stable conditions, and safeguard against cross-contamination.

How We Keep It Pure

We manufacture in our own state-of-the-art facility to ensure highest-quality standards. Production employees receive extensive, ongoing training of the safe handling of raw materials and finished products. Machine operators inspect the capsules every 15 to 20 minutes, and quality assurance specialists inspect them every 60 to 90 minutes.

In addition, we have a comprehensive Allergen SOP (Standard Operating Procedure) that prevents ingredient cross-contamination by including the following policies for flagging allergen-containing ingredients:

  • Separating ingredients throughout storage and manufacturing

  • Sterilization of all equipment after every batch

  • Training employees on the safe handling of allergenic materials and finished products

Any product containing ingredients from allergens such as soy, dairy, or shellfish is clearly labeled.

GMO Policy

All Pure Encapsulations ingredients, including those derived from corn, are GMO-free. We obtain statements from each of our suppliers certifying that the ingredients do not contain GMOs. For some nutrients, we conduct PCR testing to confirm the absence of genetically modified material.

Certified Gluten-Free

We’re proud to tell you that our gluten-free certification comes from the Gluten-Free Certification Organization (GFCO).
