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.

iHerb Customer Reviews

you must take if you supplement with vitamin D

Posted by abetterway on Nov 19, 2017 | Verified Purchase

If you take a vitamin D supplement, then you must take a vitamin K2 supplement. Vitamin D and K2 interact as partners to strengthen your bones and improve your heart health. Vitamin K is absolutely essential for protecting heart health, dental health, bone health, and more. Basically, the calcium in your body will not be properly dispersed to where it's required, and wind up where it will do damage, resulting in weak bones and solidified arteries.. In a nutshell, K2 is keeping the calcium going where it needs to go. Without it calcium would deposit in the soft tissues of the body like arteries, vein, and skin. I have had less tooth sensitivity and less plaque build up since taking this product. Although this product is expensive it is a strong dose and Thorne is a quality brand that you can trust. See my page for more honest reviews.

Thanks for your feedback!

Easy to take for supporting your immune bone support. My girlfriend has been taking Thorne K2 and she has had amazing results after her bone test. Looking forward to my test results in a few months.

The bottle is not practical anymore

Posted by iHerb Customer on Sep 17, 2017 | Verified Purchase

I like this product and have been using it for a while. However, they have changed the bottle recently and there's no integrated dropper anymore. Now you have to shake fast just to have one drop, it's frustrating and not practical.

Thanks for your feedback!

Should make a smaller bottle.

Posted by iHerb Customer on Sep 10, 2017 | Verified Purchase

Seems like a good product. I like how it doesn't have all the additives that are found in most supplements. I think however that the bottle is too big if you only take a moderate dose like I do (two drops per day). A warning: Don't overtighten the lid otherwise you will break the rubber seal.

Thanks for your feedback!

This product is easy to take.

The purity and the concentration of this supplement, in liquid form, makes it perfect for anyone to use.
