A consumer or patient with a question about using a Thorne Research product should first consult with their health-care professional. Because Thorne Research does not know a patient's health-related condition or circumstances we cannot make any recommendations or offer any advice. A consumer or patient should always consult with their health-care professional before taking any dietary supplement, especially if you have liver or kidney problems, if you are pregnant or nursing, or if you are taking a prescription medication or other dietary supplements. The Suggested Use for individual Thorne Research products is listed on the product page at the INGREDIENTS tab. The presence of a potential food allergen (such as soy, wheat, dairy, fish, etc.) for individual Thorne Research products is listed on the product page at the STATEMENTS AND WARNINGS tab. We do not provide information about an ingredient's country of origin. For questions about GMO status see the question, "Are your products GMO free?" at the FAQS link at the bottom of the page.
