Thorne is committed to producing high-quality supplements through rigorous testing, selective and well-researched ingredient sourcing, and strict manufacturing standards. We avoid unnecessary additives, binders, and fillers that may interfere with nutrient absorption. 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. What’s more, our manufacturing and warehouse facilities are inspected and certified by independent, third-party organizations, ensuring compliance with current Good Manufacturing Practices (cGMP).
