Product Overview

  • Hypoallergenic

Vitamin D/K2 Liquid, vitamins D3 and K2 in a balanced formula

  • 10 drops contain 5,000 IU vitamin D3 and 1 mg vitamin K2
  • vitamins K and D for support of healthy bones
  • in liquid for ease of dosing and titration
  • both vitamins support a healthy cardiovascular system
  • provides nutritional support for oncology patients

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 and is derived from bacterial fermentation; thus, there is no soy in the product. Vitamin K is also essential for normal cell formation and maintenance of a healthy cardiovascular system.

It is essential to maintain healthy vitamin D levels throughout all stages of life, from fetal development to old age. Vitamin D helps protect a number of important systems in the body, including healthy bones, immunity, and cardiovascular function.

Combining vitamins D and K may provide even better protection of these systems. One study in postmenopausal women found a combination of minerals 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 K, or placebo.

Thorne'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.

Really enjoying this Thorne product. Easy to use, pleasant/no taste and economical. Immediate lift in my mood. Recommended to increase your vit D intake beyond what you might get in your multi.

This is a great Thorne product, very effective, my Vitamin D levels were very low and just within a month they came up to normal levels, only taking 3 drops a day, nice tasting! KM

Th best Vit D3 supplement going

Posted by 4841706703725997263 on May 24, 2016

This D3 supplement comes in a liquid form so it is easier to digest and it is in a balanced formula with Vit K2 which is a vitamin which MUST be taken with Vit D3 otherwise in extreme cases hardening of the arteries will result. My blood serum levels of D3 have gone through the roof since I have been taking this (at approx. 30,000 iu's per day for an autoimmune disorder that I have) - and yet I have experienced zero negative side affects to date (about 6 years now) and only positive benefits. I hope this continues. Very good for healthy skin, hair and nails as well as immunity, strong bones and teeth and I am told has powerful anti-cancer properties. This is the only treatment that has had a powerful and positive effect on the autoimmune disorder that I have where my skin literally peels off in layers leaving very sore raw tissue underneath. If I stop taking the Vit D3 or reduce the dosage the condition comes back. I have tried every anti-bacterial, anti-viral and anti-fungal cream that modern medicine can provide. I've also tried all sorts of antibiotics and other medicines - none of them worked and some actually made the condition worse. Vit D3 +K2 keeps it at bay. I hope Thorne Research never stop making this product.
