The question of whether Thorne vitamins contain iron is a common one, and the answer is that it varies depending on the specific product. Unlike many brands that include iron in every multivitamin, Thorne Research formulates certain products with iron, while explicitly excluding it from others to meet diverse nutritional requirements.

According to the company, Thorne manufactures approximately 95% of its products in-house at its state-of-the-art facility in Summerville, South Carolina. This vertical integration is a core part of Thorne's business model, granting them greater control over the manufacturing process, a key differentiator for those wondering who manufactures Thorne vitamins.

While Thorne offers many high-quality supplements, some containing kosher-certified ingredients like vegetable capsules and specific probiotics, the company does not pursue full kosher certification for its entire product line. This creates ambiguity for individuals who adhere to strict dietary laws. To be confident in a product's status, it is essential to understand the intricacies of kosher certification beyond the ingredients list.

According to Thorne, the company does not exclusively use either natural or synthetic ingredients, and many of their products contain a mix of both sources. The question, 'Are Thorne vitamins natural or synthetic?' is a complex one, as the company's philosophy prioritizes efficacy and absorption over a rigid adherence to a single sourcing method. This approach is central to understanding what you're truly getting when you purchase a Thorne product.
