Thorne Vitamin D + K2 Liquid with Metered Dispenser - 1 Fl Oz (30 ml)

For more than 30 years, Thorne has been trusted by healthcare 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.

Vitamin D/K2 Liquid is a convenient way to supplement with both vitamins D and K2, which offer greater support for bones and the immune and cardiovascular systems together than either does individually.* This liquid formula can be mixed with a food or beverage for ease of use for all ages and is preserved with natural vitamin E for freshness, free of additives.

The Vitamin D/K2 Liquid formula contains well-studied MK-4 as its form of vitamin K2. We don't give much thought to our bones – until we break one. Although we might think of our bones as inert structures – as scaffolding that holds us up, as protection for the body's organs, and the structure that allows us to move about – bones are crucial to many more functions than that. Because our bones are living, dynamic, and constantly changing tissues, maintaining proper bone health is important.

Nutritional supplements provide essential support for bone health. The four most important nutrients for supporting bone health are two vitamins and two minerals – vitamins D and K and calcium and magnesium. These four nutrients synergistically help each other do their jobs, including sending calcium to the bones and keeping it out of the arteries, kidneys, and other soft tissues.*

We develop better standards for higher quality ingredients. 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, South Carolina, manufacturing facility is annually certified by GMP and certified by NSF International yearly, a well-recognized independent third-party certification organization.

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're thinking sustainably to protect our environment. 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.
