Product Overview


  • Dietary Supplement

Vitamin K2 in its MK-4 form to support bone, heart, and blood vessel health.

Vitamin K2 (as MK-4) exerts a more powerful influence on bone health than vitamin K1. K2 also supports heart and blood vessel health.* It comes in a metered bottle for ease of use.

Vitamin K2 offers significant benefit for supporting bone health – more than vitamin K1. Although vitamin K2 offers well-recognized postmenopausal bone support, because it has no estrogenic effects it also provides support to other populations as well, 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. Vitamin K2 also supports a healthy heart and blood vessels. Thorne's vitamin K2 supplies 1 mg of vitamin K2 per drop. Research shows that 15 mg three times daily can be safely used. The concentrated liquid and the bottle's metered dispenser make use easy and convenient.

Suggested Use

Take 15 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.

Other Ingredients

Medium chain triglyceride oil, mixed tocopherols.


Tamper Evident: Use only if bottle is sealed.

Store tightly sealed in a cool, dry place.

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

Missing order

Posted by iHerb Customer on April 16 2018 | Verified Purchase

I ordered 2 of these on April 2, 2018. They were not in my shipment. I was not notified that it was back ordered. Can I get a refund?

Thanks for your feedback!

One drop

Posted by iHerb Customer on February 11 2018 | Verified Purchase

Really like this stuff. Only need one drop with my daily 5 drops of Vit D. Thorne is a great, trustworthy company that makes top notch supplements too.

Thanks for your feedback!

Works like a charm

Had to have a carotid artery cleaned out. Too much free calcium in my blood. Friend told me about vit K2 to block calcium in the blood and absorbed into the bone. Been several years now and Dr said, "Don't know what you're doing, but, keep doing it!" Tests just keep getting better. Dr doesn't understand. Proof enough for me!!!

Thanks for your feedback!

This particular K2 is very effective, but new dropper works terrible

Posted by iHerb Customer on January 1 2018 | Verified Purchase

Since I started taking this product my cavities have been filling in ever so gradually, it's amazing (I only take 2 drops a day since it's so expensive, but it still works, just takes much longer to get results). However I no longer give it 5 stars, I knocked off 1 star because they changed the style of dropper on the bottle... for the worse... you can't control how many drops you're going to get. Nor can you aim it where you want it. Don't like it at all. Plus, it's (unhealthy) plastic!!! It used to be a glass eye dropper. Any chance this bottle could be changed back to how it used to be with the glass eye dropper? It just worked so much better.

Thanks for your feedback!

Wish they came in liquid gel caps

Posted by iHerb Customer on December 17 2017 | Verified Purchase

Great product but I take 45mg per day and the drop restriction takes too much time-- I wish the product came if 15 mg liquid gel caps or some faster way to get it-- thxs
