Review: Expiry date is not ok! - I’ve received vitamin today and on the bottle the expiry date is 08/12/2022. Taking into account that the product is from USA market, USA date format mm/dd/yyyy so it was expired in August. Even if the date format is different, it’ll expiry in a month which is nonsense as how can I use the whole bottle in a month. I would like the product to be replaced with the normal expiry date.
Review: Cleaned the plaque off my teeth - 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.

## Features

- Combo Effect: A convenient self-dispensing top provides accurate dosing of individual drops of well-tolerated vitamins D3 and K2, which offer greater support when taken together
- Third-Party Certified: This product has been third-party tested and certified to verify what's in the package matches what's on the label and to confirm it contains no unsafe levels of contaminants
- Trusted: Thorne is chosen by champions and trusted by 100+ professional sports teams, a proud partner of U.S. National Teams, and the #1 recommended clinical brand by health-care practitioners (2023 Health-Care Practitioner Seller Survey)

### ⭐⭐⭐⭐⭐ High-Quality Packaging (albeit unintuitive)
*by J***B on 25 May 2026*

I noticed some people complain about the bottle. I would have agreed, but it turns out that if you hold the bottle perfectly upside down and perfectly still, after a few seconds it starts dripping quite steadily. Fast enough to not feel like you're waiting forever, slow enough to stop after exactly 15 drops. This isn't spelled out in the directions very clearly, to be fair. The other options on the market for menatetrenone at this dose all seem to contain microcrystalline celluose, which isn't the worst additive, but some find it causes digestive issues. 5 stars for quality ingredients, and well-designed packaging. I don't have any evidence for the efficacy or dose accuracy aside from my own empirical experience, having compared it to other similar supplements.
