Product Overview


  • Dietary Supplement

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 Research's vitamin K2 is MK-4. Vitamin K is essential for normal cell formation and to help maintain a healthy cardiovascular system.

It is essential to maintain an optimal level of vitamin D through all stages of life, from fetal development to old age. Vitamin D helps support a number of important systems in the body, including muscle and bone health, as well as cardiovascular and immune function.

Combining vitamins D and K might provide synergistic protection of these systems. One study in postmenopausal women found a combination of minerals along with vitamins D and K maintained healthy artery elasticity, compared to two other groups of women who received either minerals with vitamin D but not vitamin K, or placebo.

Thorne Research's Vitamin D / K2 Liquid is in medium chain triglyceride oil, preserved with mixed tocopherols.

Suggested Use

Take 2 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.

Other Ingredients

Medium chain triglyceride oil, mixed tocopherols.


Tamper Evident: Use only if bottle is sealed.

I was deficient in vitamin d and while using this product that problem has been corrected. I like that it is a liquid and not another pill to take. It isn't the cheapest supplement out there, but for the reasons listed above I continue with it.

Thanks for your feedback!

Excellent Vitamin D Supplement

My Dad's vitamin D levels went from low to mid 70s, where it needs to be. Highly recommended.

great supplement, poor packaging change

I've been using Thorne's vitamin D+K2 for 2 years now, and I've been very happy with the product, but this is the first time I've purchased it that it came in an invert-to-dispense-by-drop type container, instead of a bottle with a pipette-type dropper integrated in the lid. Although I have used other products in this type of container before with no problem, this bottle would not dispense. I had to pry out the top (I did it with a chopstick,) and decant it into the old bottle with a dropper in the lid, which I had luckily not thrown out yet. I hope Thorne will switch back to the pipette style dropper, or perhaps review their supplier of this invert-to-dispense-by-drop container and find one that works reliably.

Thanks for your feedback!
