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 12/13/19 Still 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. Read more

I love the fact that the supplement is metered. Do not listen to the other reviews who evidently are so busy they don’t have a few seconds to wait for this wonderful d3 k2 to meter out. I recently bought a different d2 k3 from a superstore, only because I was out and saw it there. What a mistake!!! This different brand has a dropper but is absolutely horrible taste wise. Do yourself a favor. Stick with Thorne. No taste. Easy to use. Wonderful benefits. I have bought Thorne vitamin d3 k2 many times in the past. Perfect every time. Read more

This is my third bottle that I am ordering from the same seller. The only Vitamin D that actually works and increased my low levels, now after a year of using it daily, I am so happy with my results. It is a little expensive, but totally worth it. Read more

Does not really have a taste. Will update in a few months to see if this increased my vitamin D levels. I like this brand because it’s high quality. Research about taking vit D, you must take it with vit K for absorption. Read more

Best price, super quick delivery Read more

Best supplement I've ever used. This product delivers all of the benefits Vitamin D supplementation is supposed to deliver, from energy levels to joint pain. I use 10 drops twice a day with food at breakfast and lunch. Life changing impact since I don't get a lot of sun. Takes a couple of hours to kick in. Gives me plenty of energy. I now understand how people get through the day without tons of caffeine. Very neutral taste. Read more

Well I was concerned about taste but it doesn’t taste of anything which is great. Easy to dispense. Is it more efficient than tablets?- I don’t know but easier to take for sure. Read more

Vitamin D is the one the vitamins that MOST humans , especially in the western hemisphere, are deficient in. I think something like 80% of Americans are Vitamin D deficient. This supplement is great for a bunch of reasons. 1) TONS of doses in one tiny bottle. 600+ doses in a bottle smaller than pocket-sized hand sanitizer. 2) EXTREMELY affordable - considering you get 600 doses. 3) The delivery mechanism is WONDERFUL. I was worried because some reviews said the drops didn't come out easily. They must have had a defective bottle, or weren't turning the bottle completely upside down. It works perfectly. Make sure you turn the bottle COMPLETELY upside down. Then let 1-2 drops come out. The liquid is tasteless, odorless - so you can put it whatever you want. Protip: Vitamin D is fat soluble, unlike Vitamin C.....so you can just a larger dose a few times a week.....or you can take it daily, since it builds up! This is great because I give my elderly mother and my son doses from this bottle.....and I don't have to do it every single day like I do for myself. I just give them about 4-6 drops every 5 days or so. Read more

dispenser easy to use and control amount you wish to take, recommend Read more

Es una gran marca de confianza, en cuanto a su contenido. Pero, el motivo que me ha llevado a escribir esta opinión es lo desesperante que es que caigan las gotas, tardan bastante en caer. Pones el bote ya sea inclinado o boca abajo y tarda como unos 10 segundos en caer la primera gota. Una vez, cae la primera gota, las siguientes ya se demoran algo menos. Es la única pega que tiene. Por lo demás, pocos efectos se notan cuando se trata de algo que es a medio largo plazo. Read more

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. Read more

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.

I like it, so easy to take everyday Read more

It’s easy to use Read more

This Vitamin D + K2 liquid is a powerhouse in a bottle! It’s super easy to take, thanks to the metered dispenser that gives you exactly what you need—no guesswork, no mess. The liquid format absorbs quickly, and with 600 servings in one bottle, it feels like it’ll last forever (okay, maybe not forever, but close!). I’ve been using it daily, and I’ve noticed my energy levels are better, and my muscles feel less fatigued after workouts. Knowing it’s supporting my bones too is a nice bonus—healthy bones, happy life, right? The flavor is very mild, almost nonexistent, which is great if you’re not a fan of overly flavored supplements. Just pop it into your favorite drink or take it straight—it’s that simple. The only downside is the price—it’s a bit of an investment upfront, but considering how long it lasts, it’s totally worth it. Also, it’s important to take it with a fat-containing meal for proper absorption, but that’s standard for vitamin D. Overall, this is a high-quality, easy-to-use supplement that delivers real results. If you’re serious about supporting your bones, muscles, and overall health, this is a no-brainer! 4.9/5 Read more
