    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.

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

    Posted by iHerb Customer on Jan 01, 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!

    Terrible Sevice

    Posted by iHerb Customer on Dec 07, 2017 | Verified Purchase

    Terrible Service! Iherb sent me the wrong order including some cheap vitamin and some vasalin. I live in Canada and can grab vaselin in thw pharmacy if I need it but dont even use. UPS tried to return the packages (yes they sent two one that my stuff but I did not get and one that UPS brought to me) but iherb refused to pay for the rteturn fees. They abandonned my package with UPS and did not care I paid them my hard earned money over 160 doolars! Don't order from iberb because in cae of mistake from their part, they don't try to fix it. They don't care about you. Canadians and other foreigners, you have been warned! I

    This is an amazing product!

    It works. This is the form of K2 that was actually used in the research. This is the form that Weston A Price spoke about as well.

    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.
