Product Overview


  • Dietary Supplement

Concentrated vitamin K2 in a convenient liquid form

  • To help maintain bone health
  • To support a healthy heart and blood vessels
  • To provide nutritional support for oncology patients
  • 1 mg of K2 (MK4) per drop

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's vitamin K2 is MK-4.

Vitamin K2 appears to offer significant benefit for supporting bone health. Although much of the vitamin K2 research has been conducted on postmenopausal support for bones, because vitamin K2 does not have any estrogenic effects, vitamin K2 also offers bone support for other populations, including anorexics, dialysis patients, individuals with Parkinson's disease, those who have cirrhosis of the liver, individuals who have had a bone marrow transplant, those immobilized after a stroke, and individuals on chronic steroid therapy.

Thorne's Vitamin K2 Liquid supplies 1 mg of vitamin K2 per drop. Research shows doses up to 15 mg three times daily may be used.

Suggested Use

Take 15 drops one to three times daily or as recommended by your health-care practitioner.

Other Ingredients

Medium chain triglyceride oil, mixed tocopherols.


Tamper Evident: Use only if bottle is sealed.

If pregnant, consult your health-care practitioner before using this product.

Store tightly sealed in a cool, dry place.

I haven't used this product long enough to see if the stated benefits really work. But over time I will be looking at how my body has reacted after taking the vitamin k2 for a month and then stopping.

Thanks for your feedback!
