Vit.K is an umbrella name for multiple kinds of similar factors that do different jobs. Largely, these come from eating lots of fresh, organic, dark green leafy veggies, & certain fermented foods, like Natto. If you only eat moderate or less veggies, & no fermented foods, you are likely deficient. Different kinds of K do different things, w/ blood clotting, & where & how the body puts mineral deposits. K2 works WITH Vit.D & WITH parathyroid hormone, for instance. With Vit.K2, D absorbs & uses better, allowing better effect from lower doses of D. (Instead of “bulldozing” it in using 10’s of thousands of units to force the body to get some.) Numerous vitamins & minerals work best like that, paired with certain other ones, to get best effects, like: C+bioflavonoids; D + K2/Mk7; zinc+copper; B12+Folate; etc. Research literature states to optimally use: 180 units of K2 per each 1000 units of D3, But supplement makers & Docs are mostly ignorant & fail to give/order that. Nattokinase enzyme is excellent at helping balance that (& does a great job cleaning out arteries, safely, all by itself). ==> Vit. K1, helps most with proper blood clotting. It is only one kind of clotting factor; the body needs a number of kinds of clotting factors to do different types of it. That is the one Docs RXing blood thinner drugs tell patients Not to supplement, if they take blood thinner drugs or foods. But doc’s are largely ignorant of which kind of K, so, they caution against Any kind, failing to consider that without K, the body deteriorates worse! ==> Vit.K2/Mk7, is the kind REQUIRED to help D be absorbed & used. It is REQUIRED to help both D & Parathyroid hormone put minerals into bones & teeth; without K2, the parathyroid hormone & VitD start clogging arteries, depositing mineral lumps in soft tissue, or forming bone spurs, for instance. So, Docs being largely ignorant of that, can make cardiovascular ills worse, sooner than later. Additionally: D2 is a cheap form of D, derived from ergot (a hallucinogen, but also an anti migraine drug), which many are sensitive to. D3 is a gentler, better-absorbed version, with no known sensitivities. An excellent & balanced source of minerals is kelp, added into foods daily. There are different kinds of seaweeds, with different flavors & textures; some have specifically better nutrient profiles for cardiovascular help, like some of the brown seaweeds. Seaweeds/kelps have been & still are “survival” foods, used for many thousands of years.

Duo = two; what “fairy dust” does “Ack” mean? Why make up magic word to baffle buyers?

It's a trade mark name meant to distinguish it from the competition. It is as you say "fairy dust" to make you believe it is special. My D levels improved using this so fairy dust or not I am happy with it.

Where are these made and what is the source of the ingredients?

Made in the USA, sourced in the usa

If it has coconut oil, why do they add water to dilute the formula?

Hi I believe this is a very good product, I take it regularly. It contains 5k of vitamin D3, Mk7 and coconut oil, and has been 3rd party tested!!? So what are you worried about? How can it be diluted, if the ingredients are listed, and it's been 3rd party tested..

Good quality for a good price

I love how much vitamin D is in these vitamins and that it’s paired with vitamin K. Super smooth and easy to swallow pills with no weird aftertaste. Great price for how many you get. Would definitely recommend!

Recommended!

D3+K2 is a wonderful product. It has a 5000 ui of D3 and 100 mcg of K2. Due to Covid-19 I have been following the Zelendko Protocol as a prophylaxis and he recommends the 5000 ui of D3 per day so I was in in the market to refill that vitamin as I was running low. Nature Bell has 5000 ui of D3 so it was exactly what I was looking for. K2 is a perfect combination with D3 and all investigation I have done shows that all doctors recommend taking these supplements together. I never purchase anything without looking at reviews and Nature Bell is highly recommended by basically all users and I was not disappointed. I was so confident when ordering the product I purchased two. The pills are very small and easy to swallow. They have a wonderful coconut fragrance. They have been working as expected and seem to be very absorbent. Another factor is as I am allergic to fish I was happy to see that in addition to not containing gluten, eggs or peanuts they also do not contain any fish. I would recommend this product.
