THORNE Vitamin K2 Liquid (1 mg per Drop) - Concentrated Vitamin K2 Supplement for Heart and Bone Support* - 1 Fl Oz

I've stopped going to the dentist for teeth cleaning altogether. Adding this vitamin K2 cleaned the calcified krud off the back of my lower front teeth in 2 days! Truly amazing! Now my teeth are smooth and clean all the time. I just brush my teeth once a day -- and often I forget to do even that. I'm saving good money without the dentist 2x year.I learned about it from Richard Nikolay at Free the Animal website. He wrote: "Well, the K2 is the only one I definitely "feel." . . . Within a few days, all plaque deposits on my teeth dissolved and have not returned. This has been a big issue, as I had gum disease and two surgeries about seven years ago. Since getting off grains (probably the gluten) my gum disease has reversed completely according to the dentist. And now, my teeth are virtually always smooth. I rarely feel the need to brush them."So, I had to try it. And it worked.The vitamin K2 is a hard to get vitamin, even if you eat the best pastured eggs, butter and organ meats. It's the 'X-Factor' that Dr. Weston A. Price discovered. It puts the minerals where they are supposed to go, instead of calcifying your arteries and joints and tartar on your teeth.Be sure to get the MK-4 version of vitamin K2. The MK-7 is the plant derived form. In answer to one critic, the likely reason MK-4 doesn't hang around in the blood very long is because the body uses it up immediately. MK-4 is the form our body uses most readily. If you have concerns about this, google these two articles: Chris Masterjohn's "On the Trail of the Elusive X-Factor", and then look for Stephen Guyenet's blog post "Vitamin K2."And even though this bottle costs alot up front, you only need several drops a day -- so the bottle will last you all year.NOTE: Read all of Richard Nikolay's blogs on this. Apparently, for this to work, you need good quality Fermented Cod Liver Oil, only made by Green Pastures. I have been on that kind of cod liver oil for years. Maybe that's why I had such a dramatic effect.Bottomline: if we get all the nutrients we really need, our body should be clean and smell good -- like all primitive people were.I also stopped wheat completely (read Wheat Belly by William Davis) and bye-bye went bad breath and body odor. I only take a shower every 2 or 3 days. It is a great freedom.

It was pretty expensive but bought based on others reviews. I will see how it works and update

I give my autistic daughter 3 drops a day. I have no idea why but it improves her mood. Originally I bought the product because others who have reviewed it said that dental plaque was cut down after using it. I don't see plaque dissolving but I believe that it is likely that now after about 4 months of usage it may be a contributing factor to preventing further plaque build up on my daughter's teeth and less swollen gums. I will continue to use this because of the dental situation but even more so because of her improved moods. Initially when I gave her 15 drops as directed she did well but after about 2 weeks she started getting irritable so I stopped and worked our way back up to 3 a day. This seems to work for her. I put it inside her breakfast foods and I take a drop a day myself. At times I take vitamin D3 so K2 is essential. By the way, my daughter had been taking 1 or 2 of a different brand's mk-7 at about 90mcg daily with no effect. I wish there were more research out there about K2. I have tried to research scholarly health articles online and there is definitely an effect that mk-4 has that is different from mk-7. Maybe taking both is good but we won't go without this one.Update: I had the dentist's clean the plaque off of my daughter's teeth 6 months ago and there has been no return. When I made my son in charge of preparing my daughter's breakfast he started forgetting to put the vitamin k2 drops in (now only 2/day). For about a month her behavior deteriorated. I once again reminded him and sure enough her behavior improved again after resuming the k2 drops. She also takes magnesium and riboflavin

I have been taking the natto stuff (mk7) but kept reading all the good stuff from Chris Masterjohn and Ray Peat about vitamin k2 in the mk4 version. Obviously not about to go ham on the goose liver - and pastured eggs and milk are good but not great sources of this vitamin. I can’t eat beef liver without gagging so this stuff is it. I take 1-2 drops a day usually in a divided dose. The bottle has 1200 drops in it so it should last a long time which is good cuz it’s expensive. I keep it in the fridge. I have noticed a difference I think - some people say mk4 doesn’t stay in your blood for very long and is useless while others say that it’s being absorbed by your tissues which is where you’d want this form to go. So ultimately I’m young and healthy and trying to stay that way with a nutritional amount of this stuff (not therapeutic doses) so I guess we’ll see how I’m doing in another 35 years? People say their teeth feel great, I’d agree. I was having some jaw pain and stuff that’s gone. I think I feel a little more energetic too.Update 12/13/19Still taking this stuff and my original bottle is still good to go. I got a chest x ray done when I pulled a muscle to rule out any other issues and my bones are great. No arthritis and they’re nice and thick. I’m still pretty young but I know people younger than me that have been surprised to find out they already have the earliest stages of arthritis beginning. So anecdotally I think It’s helping keep me healthy and I’ll keep taking it in the low doses that I do.
