Brand History & Values

Douglas Laboratories has over 65 years of experience as a global leader in science-based nutritional supplements for individuals and professionals alike.

Dedicated to making premium products backed by science and clinical trials, they work with a dedicated scientific advisory board of healthcare professionals and clinicians when innovating their formulas. This allows Douglas Labs to develop clinical-grade products and protocols, and advance ongoing education for their products.

Aside from their products, Douglas Labs enjoys giving back. They support SOS Children’s Villages where they fundraise to help villages and orphaned children. They also support Global Medical, a non-profit medical group providing support to refugees. Lastly, they sponsor Trees For The Future to help farmers improve degraded land.

Speaking of supporting the environment, Douglas Labs continues to make more sustainable choices for its daily operations:

  • They use recyclable packaging and have partnered with TerraCycle
  • Are committed to reducing their greenhouse gas emissions by 20%
  • They have reduced their virgin plastic packaging by 1/3 by removing the neckbands from bottle packaging and using recycled plastics
  • By removing single-use plastics from their offices
  • Operating on renewable electricity

Premium Quality Control For Premium Supplements

Considering they are a clinical brand, it’s no surprise that Douglas Labs follows strict manufacturing and ingredient sourcing policies.

Their manufacturing facility is GMP, NSF International and NSF Sport certified; therefore, consumers can trust that they adhere to manufacturing guidelines set out by the FDA and Health Canada. Beyond those certifications, their facilities are also ISO accredited and certified organic.

They source premium quality ingredients that are GMO-free and guarantee this by obtaining certifications from their suppliers and by conducting PCR tests on other ingredients.

When creating their formulas, they understand the varying needs of their consumers and clinician’s patients. They consult with their scientific advisory board and stay up to date on the latest research and clinically validated ingredients to create cutting-edge formulas. All of their premium supplements are tested for safety and efficacy and customers can trust that all allergens are disclosed on the label and they follow comprehensive procedures to prevent cross-contamination.
