Thorne’s Vitamin D / K2 Liquid is a powerful‚ hypoallergenic formula that provides the great health benefits of both vitamin D-3 and vitamin K-2 in liquid form. These two crucial nutrients deliver important support for the health of your bones‚ while also promoting the healthy functioning of your cardiovascular system.

Vitamin D3—This fat-soluble vitamin has a crucial role in preserving healthy levels of calcium in the blood. Your body uses vitamin D to move calcium from the bones into the bloodstream when it’s needed. Vitamin D is known for its importance for healthy bones and teeth. Vitamin D-3 is the form of the nutrient most often used in supplements. Despite its classification as a vitamin‚ Vitamin D behaves in a way that is similar to a regulatory hormone for calcium and bone metabolism. Adequate amounts of vitamin D are critical for ensuring regular calcium absorption and maintenance of strong calcium plasma levels. Maintaining proper levels of vitamin D throughout life—from fetal development to old age—is crucial‚ as the vitamin also works to protect the immune system and heart.

Vitamin K2—This vitamin is actually a series of molecules known as menaquinones; the menaquinone that has been researched most extensively is MK-4. Thorne's liquid supplement contains the MK-4 form of vitamin K-2‚ which is derived from bacterial fermentation; as a result‚ there’s no soy in this product. The form of vitamin K in this supplement has greater influence on bone health than vitamin K-1. Vitamin K is also essential for normal cell formation and maintenance of a healthy cardiovascular system.

Combining vitamins D and K may provide even more support for your body than either one alone. One clinical study of postmenopausal women revealed that a combination of vitamins D and K (along with additional minerals) better maintained healthy artery elasticity. Each bottle of Vitamin D / K2 Liquid by Thorne contains one ounce (30 milliliters).

Thorne strives to provide pure‚ high-quality supplements to people looking to enhance their health and well-being. Its products are commonly used in prestigious research studies‚ and are recommended by many doctors and health care practitioners. The company always goes the extra mile to ensure that Thorne dietary supplements are safe and effective for immune-compromised‚ allergic‚ and chemically sensitive patients.

    • No dropper included.

      from Nashville, TN on 7/31/2022
      Should they have a dropper? Mine did not, and I ended up wasting a lot. Have been apprehensive about ordering anything using drops, and that is my preference. I really cant give it an honest rating because I don't know whether the dropper was not included. Wasted my money. I know that this is a good product though.
