Product Overview


  • Dietary Supplement

Supports healthy bones and muscles, as well as the cardiovascular and immune systems.

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.

Both vitamin D and vitamin K2 support bone and muscle health, along with cardiovascular health and immune function. It is important to maintain an optimal level of vitamin D in the body through all stages of life, from fetal development to old age. Vitamin K2, a series of molecules known as menaquinones, exerts a more powerful influence on bone than does vitamin K1. The vitamin K2 in this formula is the well-studied MK-4. Combining vitamins D and K can provide greater support of the immune and cardiovascular systems than each offers separately. For example, vitamin D is necessary for calcium absorption, and vitamin K is important for directing calcium to the bones and away from the soft tissues, such as blood vessels and kidneys. Thorne's Vitamin D/ K2 Liquid also provides nutritional support for oncology patients.

One study in postmenopausal women found a combination of minerals along with vitamins D and K maintained healthy artery elasticity, compared to two other groups of women who received either minerals with vitamin D but not vitamin K, or placebo. Thorne's Vitamin D/K2 Liquid is in medium chain triglyceride oil, preserved with mixed tocopherols.

Suggested Use

Take 2 drops one to three times daily or as recommended by your health-care practitioner. Invert bottle to dispense individual drops. May be added to food or mixed in beverages. Do not refrigerate

Best Clean D3/k2

Great brand with clean products and best d3 product in my opinion with the combination of d3/k2. And always best when it’s liquid and you can get a perfect dosage, for everyone.
