Vitamin K2 is a fat-soluble vitamin, playing a central role in regulating calcium metabolism. All over the body, vitamin K2 is needed to activate vitamin K-dependent proteins, which help get calcium to where it's needed and prevent harmful deposits anywhere else.

Our product development and consultancy services

Years of experience in our sector, along with mountains of consumer insights and a passion for creating innovative products based on vitamin K2, help us deliver a range of services that take sophisticated science and turn them into simple solutions for our partners and the people that count on them.

Let experts guide you

Why we need K2

Vitamin K2 is an essential vitamin that’s needed all over the body, at every stage of our lives. It’s responsible for activating calcium-binding proteins, helping calcium get to where it’s needed. Sometimes it’s for building and maintaining healthy bones and teeth, and other times, preventing harmful calcium deposits.

K2 in food

Studies show that many of us around the world aren't getting enough vitamin K2.

For a long while, human diets provided plenty of vitamin K2. But somewhere along the way, that stopped being the case, and a lot of people started developing vitamin K2 deficiency.

Dietary recommendations range between 75 to 120 mcg per day, but these can be higher for certain populations. No matter who we are, or what we do, we all need vitamin K2.

K1 and K2

We’ve seen a lot of confusion around the differences between vitamins K, K1 and K2. We’d like to help clear things up.

Vitamin K is a fat-soluble vitamin that exists naturally in multiple forms, K1 (phylloquinone) or K2 (menaquinone).

Vitamin K1 is found in high amounts in leafy green vegetables. It has a short half-life, and is mainly used by the liver to support blood clotting. Deficiencies are rare.

Vitamin K2: also known as menaquinone, is normally found in animal-derived and fermented products. Unlike K1, Vitamin K2 is used not just by the liver, but also by our bones and vasculature.

It activates many calcium-binding proteins, such as osteocalcin or matrix Gla protein, which play roles in building and maintaining bone mass, and preventing calcification of the arteries and other soft tissues, respectively. Many of us are deficient in vitamin K2.

K2 Subtypes

Vitamin K2 has dozens of subtypes, called menaquinones (all named after the length of their molecular chain, now that you ask). The most well-known menaquinones are menaquinone-4 (MK-4), and menaquinone-7 (MK-7). Due to its exceptionally high bioavailability and long half-life, supplementation in the form of vitamin K2 as menaquinone-7 (MK-7) is recommended, as this means there’s enough vitamin K for the carboxylation of target proteins outside the liver.

Cis and trans

In nature, menaquinones are found in a linear configuration, called trans. This is what’s known as the bioactive form, the form our bodies can use in food supplements.

Because of inferior production methods or stability issues, it can take a non-linear, cis shape. Cis forms cannot fit in their target, and thus fail to activate vitamin K-dependent proteins. This makes them biologically inactive.
