Thorne Research

With a desire to empower people to live healthier lives, Thorne Research is a clinical supplement brand that provides personalized, scientific testing and supplement solutions.

Thorne Research Brand History

Founded in 1984, Thorne Research is an American professional supplement brand in Seattle. Thorne is trusted and loved by practitioners, patients and consumers alike.

In 1990, the company moved to Idaho and by 2010, they merged with Diversified Natural Products. In 2016, Thorne moved to the mass market and shifted from a practitioner-centric approach to a direct-to-consumer one. In 2018, they expanded from supplements to at-home health testing kits to help people better understand their well-being.

Thorne is not only loved by consumers but they are also loved by industry leaders and have the awards to prove it. Some of their awards include the Fast Company Award for innovation, the MedTech Breakthrough Award, the NutraIngredients USA award, the American Business Award, plus many more.

Quality Control & Testing Protocols

Being a clinical-grade supplement brand, Thorne takes quality measures and testing seriously. The manufacturing facilities where they make their clean, high-quality supplements are U.S. Food and Drug Admin (FDA) approved, and their sports line is NSF-certified for purity and efficacy.

All of their formulas include the purest ingredients and each product is tested four times throughout the manufacturing process. Their testing is done both in-house and through third parties. The four stages include:

  • Round 1: Analyze the purity of raw ingredients at in-house labs and screen for contaminants
  • Round 2: In-process testing to ensure the correct amount of ingredients are used in their formulations. This stage also checks for bottle, label or capsule defects.
  • Round 3: Finished product testing to confirm identity, potency and purity and confirm no microbiological contamination has occurred
  • Round 4: Stability testing to confirm the shelf life of finished formulas

Beyond their testing procedures, all of their products are free from unnecessary ingredients, like fillers, additives and allergens.

You can also feel confident taking Thorne supplements because they conduct clinical research and review medical literature that substantiates each ingredient used. This research involves conducting clinical trial programs for each formula to guarantee safety and efficacy.
