Product Overview


  • Dietary Supplement
  • Effective in Maintaining Bone Health
  • Combine with Vitamin D for Optimal Bone Health
  • Supports 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, some of which are found naturally in fermented soybeans. 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.

Well worth the money!

A disclaimer: I am using this in conjunction with Dr. Price's fermented fish oil and high vitamin butter oil (a natural source of K2-M4). It is this combination that Dr. Price was convinced worked wonders in his test subjects. I've been taking this combo for over 10 years now ... I just had a complete vascular scan and I have ZERO calcification of my arteries. (A 40% blockage is considered normal for my age group) I decided to augment my dose with this Thorne Research version because the butter oil capsules do not state the strength of the dose. I am very happy to be using a natural source of K2-M4, but always wondered if I was getting enough. I have been using the increased dose for 7 months now and I believe that I have three teeth that are re-mineralizing. I have had 'pockets' for years and years and they have filled in. (This was on the back of the three bottom, front, teeth.) I'm a very happy camper!

The best K2, period

Posted by 4943797960547833871 on Nov 03, 2015

Vitamin K2 works in conjunction with vitamin D, calcium and magnesium to build strong bones and teeth. It's also a crucial substance for making sure that calcium isn't deposited in your arteries (atherosclerosis) thereby helping to prevent heart disease and poor circulation. For men over 40 it's a great supplement to make sure that a certain part of the body keeps working the way you want it to, if you catch my drift… For menstruating women, it can help decrease excess bleeding. All in all, a key supplement for anyone wanting to improve their long term health. Update: I've now switched to Carlson Labs 5 mg capsules, which I find to be more effective and simpler to use.
