Quality Built Into Every Step

From supplier qualification through manufacturing, testing and finished-product storage, Patient One follows rigorous quality procedures at every step — even the steps you never see.

Quality Control From Start to Finish

Patient One supplements are manufactured in the USA, with our primary manufacturing facility located on Long Island, New York. Because product quality depends on more than just ingredients, we have an extensive quality control program that also focuses on:

  • Sanitation

    Each piece of manufacturing equipment is dismantled and sanitized before every production run.

  • Contamination Control

    Strict limits and testing procedures help manage potential microbial, heavy metal, pesticide and allergen risks.

  • Traceability

    Tracking systems provide lot-level traceablility for raw materials, in-process materials, and finished goods.

  • Documentation

    SOPs, batch records and extensive documentation ensure consistency from batch to batch.

  • Manufacturing Conditions

    Temperature, humidity and dust are controlled within manufacturing areas to protect sensitive materials and manufacturing processes.

  • Controlled Warehousing

    Raw materials and finished products are kept in carefully controlled conditions to help protect quality and stability.

4 Rounds of Testing

Our commitment to quality starts long before a product reaches you.

  • Raw Material Testing

    All raw materials are quarantined upon receipt for testing prior to manufacture. Ingredients are tested for identity and to confirm that they are potent and free of contaminants.

  • In-Process Testing

    Throughout manufacturing, we monitor critical quality parameters to ensure consistency and accuracy at every stage.

  • Finished Product Testing

    Before release, each batch of finished supplements undergoes testing to confirm ingredient potency, overall purity and specification compliance.

  • Stability Testing

    We evaluate products over time to confirm they maintain their quality, potency and stability throughout their shelf life.

NSF GMP Certified

NSF cGMP Certification

To validate our quality control measures, our manufacturing facility is NSF-certified and cGMP (current good manufacturing practices)-certified, and audited annually to ensure ongoing compliance with rigorous requirements and quality standards.

The NSF/ANSI 455-2 certification is an independent standard that builds on the FDA's cGMP requirements for dietary supplements and incorporates industry best practices beyond basic federal requirements.
