Thorne Research Is Committed to Purity

Consumers of nutritional supplements see various tag lines such as: "We use only the purest ingredients" advertised by various supplement companies. It could very well be that these other vitamin companies really believe their own hype. Or, maybe they just don't know another way. In any event, for over 25 years, Thorne Research has been the standard by which other supplement companies are judged for product purity. Medical doctors, chiropractors and nutritionists rely on Thorne Research as the supplement manufacturer they trust when prescribing supplements for patients of theirs that have problems such as extreme allergies, chemical sensitivity or a compromised immune system.
