Product Description

Size:1 Fl. Oz. - 1 Pack  |  Product Packaging:Standard Packaging

Thorne Research - Vitamin D/K2 liquid contains vitamin K2 and vitamin D. 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.

Yes, you can have a vitamin D deficiency if you live in Florida!**

I am familiar with Thorne products and have used them in the past, with great success. That said, this D/K2 liquid isn't working for me near as well as the cheapie "Spring Valley" gel caps. Don't know why...

For the past year I have had increasingly terrible leg pain, joint aches, and low energy. Finally I went to my local physicians' network and was given a thorough test. My D3 level came back at 19--very low, deficiency level. The best levels are somewhere between 60 and 90. But my doctor, new to this country, looked at the 19 and said "very good" (I know, time to get a new doctor). From that point on I knew I was in charge of my own recovery.

Not knowing what to do next, I raced home to look up more info on the net. I learned that the correct dosage for me was 6000 to 8000 iu daily for 3 months, to be retested again. Fortunately, I had a bottle of softgels on hand that a visiting relative had left behind. They were 2000 iu per gel, so I began taking 4 a day, with magnesium. Within a week my leg pains and joint aches had much improved, and by 2 weeks I could feel some semblance of a former self. At the end of week 3 I was really energized. (Please know that it can take 6 months to a year for complete physical recovery).

With further research I learned K2 is optimal when taking D3. So I purchased the Thorne and started taking 16 drops daily, the equivalent of the softgels I had been taking. After about 3 days I noticed I wasn't feeling quite so peppy and I ached a bit more. Thought it might be a virus, so I continued with the Thorne. After a week I hadn't improved, just kind of felt the same, so I switched back to the softgels.

I like this liquid vitamin. It delivers 500 IU of Vitamin D3 and 100 mcg of K2 in one drop. There are 1200 servings in this small container. I add it to my homemade vegetable juice every morning. Taste is undetecable, it's hard to taste one drop of anything.

I bought this because I did extensive research on tooth decay and discovered a connection between this nutrient and proper remineralization of teeth. My son had enamel hypoplasia and this product has become part of my protocol to regrow his enamel. I use it in conjunction with fermented cod liver oil and some other nutrients. It appears to be working as his mottled crevices are filling in and his enamel looks to be getting whiter and harder.

After three weeks daily usage noticed the plaque buildup(been about a year since last dental cleaning) is gone from between my bottom front teeth. Regularly floss every other day and now the floss no longer snags on the plaque buildup on my front teeth which are now smooth with no rough edges.

Update April 10, 2013 just got back from the dentist for my 18 month checkup. He had a note to check the status of a cavity starting on one of my front teeth, he did a few double checks of his notes and my teeth as to his surprise he could not find any evidence of the cavity now. Trip cost me $263.00 = $79 for recall exam, $79 for polishing, $30 for a fluoride treatment, and $75 for scaling(teeth cleaning that took about 45 seconds as she could not find much). Great independent confirmation for me at least this treatment is working.

After tests showed was low in Vitamin D, did some research and discovered the re-mineralization of teeth connection of Vitamins K2-MK4, D, and A. Vitamin D must be taken with fat(food) to be absorbed.

Details:
1) New: Take 1 drop daily under tongue of THORNE RESEARCH - Vitamin D/K2(as MK4) Liquid(I take this myself not from Naturopath)

2) New: Take 5 drops daily under tongue of "Pure Encapsulations Vitamin D3" (1 drop is 1,000iu), as it muscle tested(applied kinesiology) better for me than any other Vitamin D supplement with my Naturopath.

UPDATE: After a week went back to the Naturopath and retested dosage, now just need a combined total of four drops of the Thorne and Pure products.

Very Effective and Easy Way to get D3/K2 in your diet! This can be added to almost anything, and very easily added to anything that is warm (K2 is not degraded when warm/heated).

I've had a sub-optimal Vitamin D level for a few years, at least...I've only been having it tested since 2012. I was taking Vitamin D supplement pills every day, which were seemingly not doing much to raise my level. I also tried prescription D2 50,000 IU/week on my doctor's rec - did not raise my level. It hovered around 20 no matter what. In Aug. 2014 my level was 23. I was totally frustrated. Research led me to a Vit D/K2 combination and this product. I ordered it on October 11. It was delivered literally the next day, when I began taking it. Each drop is 500 IU of Vitamin D. I am taking 10 drops a day, 5 in the AM and 5 in the PM, a total of 5000 IU per day.

Retested Nov. 18, just got my results: Vit D level 42!! So, I am a big fan of this product and will continue to order it (although I still have plenty left. The bottle lasts a long time.) For me, it's working.
