Product Overview


  • Dietary Supplement
  • Hypoallergenic

Vitamin D/K2 Liquid, vitamins D3 and K2 in a balanced formula

  • 10 drops contain 5,000 IU vitamin D3 and 1 mg vitamin K2
  • vitamins K and D for support of healthy bones
  • in liquid for ease of dosing and titration
  • both vitamins support a healthy cardiovascular system
  • provides nutritional support for oncology patients

Vitamin K2 exerts a more powerful influence on bone than does vitamin K1. Vitamin K2 is a series of molecules known as menaquinones. The most common and well studied of the menaquinones is MK-4. Thorne Research's vitamin K2 is MK-4. Vitamin K is also essential for normal cell formation and maintenance of a healthy cardiovascular system.

It is essential to maintain healthy vitamin D levels throughout all stages of life, from fetal development to old age.Vitamin D helps protect a number of important systems in the body, including healthy bones, immunity, and cardiovascular function.

Combining vitamins D and K may provide even better protection of these systems.One study in postmenopausal women found a combination of minerals 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 K, or placebo.

Thorne Research'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.
