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.

it works!
i'm i a hate/love relation with this particular product. first of all, i have to mention this is the first and only vit.k2 product i have tried so far. I have taken only 4 drops/day and have noticed the following: - significantly rediced hair loss: i have lost a lot of hair in the past...17 years!!! and i know for sure this has stopped that; how it worked? i believe it has to do with the fact that k2 lowers insulin resistance which gets me to the second point - no craving for sweets! and i mean absolutely no craving! and it also helped me eat only 3 large meals a day with no snacking! - almost no tartar while taking this - (the bad:) sleep troubles - and this was bad. i can sleep for only 4 hors/night whenever i take this vit. it takes a few days for this problems to set in, but unfortunately they do even when i take only 2 drops/day. I guess my next try with vit. k2 product with be the mk7 version (i.e. the "natural" form) or better fish ore! Good luck to everyone else with this product! i guess it is worth a shot. hopefully not everyone gets sleep trouble while taking this.

Don't be put off by the huge price tag
I can't emphasize how important vitamin K2 is to our body. One of the main reason why I started taking K2 supplements is due to atherosclerosis(hardening of arteries walls), which can be caused by calcification of the arterial walls. Vitamin K2 is amazing simply because it can reverse the damage done by arterial calcification; vitamin K2 is used in Japan to treat severe arterial calcification. What K2 does is redirecting the calcium inside our body to the correct places ie bones instead of letting the calcium build up on the arterial walls. I can testify that after taking Thorne's vitamin K2, I felt so much better. I must admit that I am currently on a few supplements but the addition of this simply made me feel a whole lot of difference. Concerning the price tag, if you were to look at the nutrition label, each drop of liquid is worth 1mg of vitamin k2, and each bottle contains 1200 drops. Now for referencing, most vitamin K2 caps contain only 100mcg per caps. So basically just one drop of this is equivalent to 10 capsules worth of K2! My daily intake is around 9 drops, split into thrice daily(3x3drops). Something to note is that vitamin K2 does not stay long in the body so taking the dose throughout the day is actually much more beneficial for the body.
