A Daily Dose of Pure Vitamin K2 for Cardiovascular and Bone Health

Food-based from Non-GMO Chickpeas not Soy; Premium Form for Maximum Bioavailability

A growing body of clinical evidence 1 is showing that Vitamin K2 is as important as Vitamin D3 for the body to process calcium properly.

What do calcium and goat herds have in common? They both can do amazing work when reined in, but can be destructive if allowed to range free. Vitamin K2 is like a nippy border collie that chases calcium out of the arteries and binds it to the bones, where it’s needed. 2,3 Without enough Vitamin K2, too much calcium builds up in the arteries and bones get weak. This may leave you vulnerable to a double whammy of cardiovascular disease and osteoporosis.4

Vitamin K2 was discovered fairly recently. Nutritional scientists are still mapping the full extent of its role, but the preliminary research is exciting. K2 appears to activate at least 17 different proteins and work synergistically with several other vitamins.5,6

It’s hard to get your daily dose of Vitamin K2 from foods that most of us eat on the regular. Natto, a fermented soy product, offers the highest concentrations.12 Because we are polite Canadians, we will simply say that natto is an acquired taste. As importantly, lots of people are sensitive to soy.

We developed Nested Naturals Vitamin K2 to give all of our friends an easy, reliable way to get the optimal daily dose of this essential vitamin. It is made from fermented chickpeas rather than soy. We use the most known bioavailable form of Vitamin K2, because if your body can’t absorb the nutrients, what’s the point?

Bonus: Vitamin K2 works synergistically with Vitamin D3. Taken together they can amplify the positive effects of bone health and cardiovascular function.13,14 Nested Naturals Vitamin K2 is formulated to pair with our premium Vitamin D3 which offers 5,000 IUs of liquid sunshine.

Important: Vitamin K2 may counteract the effects of anticoagulation therapy, and therefore is not recommended for patients on blood thinning medications such as Warfarin.15

A Missing Link for Bone and Cardiovascular Health

Blood Clotting

Vitamin K is a cofactor for the protein Prothrombin, which plays an essential role in regulating the clotting process.17 Supplementing with Vitamin K may be important for individuals whose blood doesn’t clot easily or for those that have been taking Warfarin for an extended time.18,19 Please consult your doctor for recommendations for Vitamin K and bleeding issues.

Strong Bones

Osteocalcin is a protein that plays a critical role in bone metabolism and it needs plenty of Vitamin K2 to work its magic.23 Studies suggest that osteocalcin binds calcium ions to bones, which strengthens them. It also appears to assist in bone remodelling as individuals age.24,25

Heart & Arterial Health

Research suggests that Vitamin K2 may help prevent calcification of the arteries, a risk factor for developing heart disease.20, 21 Vitamin K2 is a cofactor for the protein MGP which has been shown to support a healthy heart by scrubbing arterial walls and clearing out excess calcium.22


Preliminary evidence7, 26 suggests that Vitamin K2 may help ameliorate the coloration of bruising, dark eye circles, pimples and stretch marks. More research is needed in this area.

Your Questions, Our Answers

See the most popular questions asked about Vitamin K2.

Where is Nested Naturals Vitamin K2 sourced?

Our Vitamin K2 is made from fermented chickpeas. We are relentless about sourcing the best, most natural, most ethically produced ingredients available. While other brands cut corners by using low quality K2 from China, our source is NattoPharma’s Natural MenaQ7, which is the best documented, commercially available natural vitamin K2. It is manufactured in Indea and known for its purity and premium quality guarantees.

Is this Trans form of Vitamin K2?

Nested Naturals Vitamin K2 is 100% Trans form. Vitamin K2 comes in two forms: Trans and Cis. Studies suggest the body can only use the Trans form. 16 Many Vitamin K2 supplements try to keep costs down by using a cheaper mix (often 50/50) of the Trans form with the unuseable Cis form. We don’t think that’s right.

We use MenaQ7 which is natural Vitamin K2 and >99% Trans form and non-racemic (meaning it DOES NOT have equal amounts of both isomers).

Why doesn’t Nested Naturals Vitamin K2 contain Natto?

Natto is made from fermented soybeans. We made a conscious choice to avoid soy because it’s a common allergen. Instead, Nested Naturals Vitamin K2 is made from fermented chickpeas.

What is rice flour doing in Nested Naturals Vitamin K2?

Rice flour helps flow the supplement ingredients into the capsule. Miniscule amounts are used during the manufacturing process. You’ll find it listed under “Other Ingredients” on our label because we believe that you deserve to know everything that goes into our supplements and your body.

What is vegetable cellulose and what is it doing in Nested Naturals Vitamin K2?

We use vegetable cellulose to make our gel-caps. We’re proud to say that our capsules are vegan and don’t include any animal parts.

I’m Vitamin K confused! Should I be supplementing with Vitamin K1 or K2?

The body uses both types of Vitamin K, but it’s likely that you get enough K1 from your diet. 12 Vitamin K2 is less plentiful in the food that most of us eat on the regular, so supplementation may be necessary to get your daily dose. If you’re looking for maximum bone health benefit, K2 is the winner because research suggests 28 that it plays a more substantial role than K1.

One of the best MK-7 products on the market. Buying directly from the company is also recommended, they're quite efficient in shipping.

You have a good product and great service. I found out from a friend and you measure up to her rave review. Thanks, Page from VA
Hi - thank you for checking in. I am taking the k2 I ordered from you to help my bones absorb calcium. A lot of people don't realize you need D3 and K2 to optimize the absorption of calcium. So I can't actually see the benefits, but I am hoping the k2 helps my bones, and I will find out when I have my next bone density scan. Also looking for good quality calcium, maybe eggshell calcium. Do you carry anything like that? Thank you again, Donna
My brother and I have been taking this and we swear that this has relieved our neck pain! I tried other brands and did not have the same results. Go figure.
I have only been taking it for a short time, but I am happy with the purchase. I didn't want a soy product.
I received my order safely and the customer service was friendly and helpful. I've only just started taking the vitamin K2 so it's too early to review it yet.
Kevin A
Quality product. Uses the correct MenaQ7 (natural) as there are actually 3 different kinds of MenaQ7. The other 2 are either soy based or synthetic. Plus it has only two other ingredients. Rice flour and vegetable cellulose. Can't get better than that in looking for a quality K2 supplement.

I'm grateful to be able to purchase this high quality product after reading of the need for it. My reading included material from numerous trusted sources.
It's been 24 days since I began taking this product. First impression on opening the package ... I was disappointed to find the bottles were plastic and not glass. The website picture of the product looked like a glass bottle. In paying so much more for this product only to find it stored in plastic, I wondered: If you go to the trouble of making what you claim to be a superior supplement, why bottle it in plastic, which we know is harmful to human health? Moreover, even more critically, we know plastics are killing the planet and we need to stop using it where possible. FYI: Once a plastic product is made, it is here forever. Plastic can only be recycled into another form of plastic, and that takes indecent amounts of energy, and only a severely limited amount of plastic is ever recycled contrary to what most people believe. Most plastic waste in North America is dumped in the oceans. I’ve tried two other K2 supplements on the market made from chickpeas, both costing less than this one, one of which is bottled in glass, and the other of which is considerably cheaper than this by more than half the price. Comparing Nested Natural to those, I find no difference. I bought this product expecting something more for all that extra money. I did not get it. Bottom line — I feel ripped off. I would NOT buy this product again at this price. It is ridiculously overpriced.
