What makes Thorne supplements high quality?

Thorne produces high-quality supplements through rigorous testing, well-researched ingredient sourcing, and strict manufacturing standards. We avoid unnecessary additives, binders, and fillers that may interfere with nutrient absorption.

How does Thorne test its supplements for quality?

To confirm the purity of our ingredients, the potency of our formulas, and the absence of all contaminants, we carry out a minimum of four rounds of testing on every product we manufacture. 100+ Thorne employees are dedicated to ensuring quality.

Are Thorne supplements clinically tested and safe?

Thorne partners with researchers and conducts clinical trials to support the efficacy of our products. Our team of doctors and medical experts substantiate each ingredient in every formula based on extensive clinical research and medical literature.

Why are Thorne products more expensive than other supplements?

When it comes to the health of our customers, we never settle. Thorne products may be priced higher than some others because of our commitment to quality at every step. We don’t simply meet the standard in dietary supplements — we set the standard.

Where are Thorne supplements made and where are the ingredients sourced from?

Located in South Carolina, Thorne manufactures supplements in the USA using globally sourced ingredients. When it comes to ingredient sourcing, we seek out only the highest-quality ingredients, selecting each one for its purity and effectiveness.
