Vitamin D supports healthy teeth, bones, and muscles, as well as cardiovascular function and immune function. In its D3 form, Vitamin D is more potent and better absorbed than in its D2 form. Thorne's Vitamin D supplements support healthy bones and muscles, cardiovascular function, and immune function. Thorne's vitamin D contains no lactose and no preservatives like BHT, BHA, sodium benzoate, and sorbic acid. Easy to take protocol: take one capsule one to three times daily, or as recommended by your health professional.

For more than 30 years, Thorne has been trusted by health-care practitioners who prescribe our products to their patients. In addition, our products are now recommended by U.S. National Teams and multiple professional sports teams for their elite athletes. Thorne products are a testament to Thorne's mission to provide high-quality supplements that are tested for quality, safety, and efficacy.

Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility - and ultimately better health. We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States. Our Charleston, SC facility is third-party certified.

Thorne has invested in two state-of-the-art in-house laboratories that enable us to conduct four rounds of testing, including raw material testing, in-process batch testing, finished product testing, and expiration date stability testing for each lot of product that we manufacture. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards.

Thorne is chosen by champions and trusted by 100+ pro teams. Thorne is the only supplement manufacturer to collaborate with Mayo Clinic on wellness research and content. Thorne is also a proud partner of 11 U.S. Olympic Teams.
