Thorne Research Vitamin D/K2 Liquid


Give your bones, muscles, heart, and immune system a boost with Thorne Research Vitamin D/K2 Liquid, a superior formula that combines two of the most important vitamins — D and K2! These two superhero vitamins work synergistically to support nearly every system in the body!  Vitamin D deficiency is widespread throughout the US.


After all, most of us spend the majority of our time indoors! But even those who do get some sun are often still low on Vitamin D. The worst part about it? Vitamin D is essential for immune health, brain health, cardiovascular function, and much more! Vitamin K2 is also a vitamin that people are commonly deficient in. It’s very difficult to get from the diet alone. It helps with blood coagulation and to distribute calcium throughout our bodies properly.


It also works with vitamin D to support our bones.  Combined, these vitamins also support our immune and cardiovascular systems. In fact, combining these two vitamins offers far greater support to both the heart and the immune system than each offers separately!

Cautions: Keep out of the reach of children. Consult a physician before taking this product if you are pregnant, nursing, taking any medications, or have a medical condition. As vitamin K interferes with the effect of anticoagulant drugs (like Coumadin), the concurrent use of these agents should be avoided.

FAQs About Thorne Research Vitamin D/K2 Liquid

Q: Does this give you both vitamin D and K2 in one dose? A: Yes. Two drops give you 1,000 IU of vitamin D3 and 200 mcg of vitamin K2 as menatetrenone, so you’re getting both in a tiny serving.

Q: How should I take it? A: Take 2 drops one to three times a day. You can put it straight in your mouth or mix it into food or a drink. No refrigeration needed.

Q: Why does it pair D3 with K2? A: Because they work well together. D3 helps your body absorb calcium, and K2 helps move that calcium where you want it, like bones, instead of soft tissue.

Q: My doctor said to be careful with vitamin K. Is this one a problem with blood thinners? A: Yes, it can be. This has 200 mcg of K2 per 2 drops, so if you take Coumadin or another anticoagulant, check with your doctor or pharmacist before using it.

Q: I've heard liquid vitamin D absorbs better. Is that true here? A: Usually, yes. This one uses an MCT oil base, which can be a good fit if you prefer drops or just don’t want another capsule to take.

Q: Should I take this with food? A: I’d take it with a meal that has some fat. D3 and K2 are fat-soluble, so that’s usually the best way to take them.

Q: Is there anything else in it besides D and K2? A: Not much. The other ingredients are medium chain triglyceride oil and mixed tocopherols.
