What Is Vitamin K2?

Vitamin K is actually two different vitamins doing different jobs. K1 (phylloquinone) is the one in leafy greens, and your body uses it mainly for blood clotting. K2 (menaquinone) is the rarer one, found in fermented foods and some animal products, and it does something completely different.

K2 activates a protein called osteocalcin, which binds calcium and pulls it into your bones and teeth. It also activates matrix Gla protein, which removes calcium from your arteries. Without K2, calcium that gets absorbed (especially when you're supplementing Vitamin D3) doesn't end up where it should. It can drift into the soft tissues, including the lining of arteries.

This is the calcium paradox: high calcium intake without enough K2 has been linked to harder arteries even while bone density doesn't improve as much as it could. K2 is the traffic warden directing where the calcium goes.

Most multivitamins leave K2 out entirely, partly because awareness of it is recent (the research really started in the late 1990s) and partly because the MK-7 form is more expensive than D3 or C. We include it because if you're taking D3 anyway, K2 is the partner it needs to work properly.

MK-7 The bioavailable form of K2

There are several types of K2, named MK-4 through MK-13. MK-7 has the longest half life in the body (around three days), meaning a single daily dose stays active far longer than the shorter chain versions.

D3 + K2 The pair that needs to work together

Vitamin D3 increases calcium absorption from food. Vitamin K2 then activates the proteins that direct that calcium to bones and teeth. Taking D3 without K2 can let calcium accumulate where you don't want it.

80µg Per serving, the clinical research dose

Most research on K2 MK-7 uses doses between 45 and 180µg daily. We sit in the middle at 80µg, the level shown in studies to be meaningful while staying well within safety limits.

What K2 Actually Does

K2's benefits are slow and structural, not the kind of thing you feel within a week. The relevant outcomes (bone density, arterial flexibility) are measured over months and years, not days. Which is why K2 is one of those quiet, long term supplements that pays off through consistency rather than punch.

It's also why most people don't get round to it. Taking it as part of Daily Greens+, alongside the D3 you're already supplementing, is the easy way to actually stick at it.

Bones Calcium routed to bone tissue

K2 activates osteocalcin, the protein that incorporates calcium into bone matrix. This is why K2 supplementation, especially alongside D3, is associated with better bone density outcomes than D3 alone.

Arteries Calcium kept out of soft tissue

Matrix Gla protein, activated by K2, removes excess calcium from arterial walls. This is why low K2 status is linked to higher arterial calcification risk, particularly in supplementing populations.

Teeth Dental tissue maintenance

Your teeth are made of the same calcium based mineral matrix as your bones. K2's role in calcium placement applies to dentin and enamel maintenance as well.

Synergy The completion of the D3 story

If you're already supplementing D3 (and in the UK, you probably should be), adding K2 closes the loop. You're not just absorbing more calcium, you're putting it in the right place.

Vitamin K2 Questions

What people ask before they try it.

What's the difference between K1 and K2?

K1 is in leafy greens and is mainly used by your body for blood clotting. K2 is found in fermented foods and animal products and is used to direct calcium to bones and teeth. They're different molecules with different jobs.

Why MK-7 instead of MK-4?

MK-7 has a much longer half life in the body, around three days versus a few hours for MK-4. This means a single daily dose of MK-7 keeps working all day, whereas MK-4 needs multiple doses to maintain levels. MK-7 is the version used in most modern research.

Is K2 safe if I'm on blood thinners?

If you're on Warfarin or any vitamin K antagonist, talk to your GP before taking any Vitamin K supplement, K1 or K2. The interaction can affect dosing. Most other blood thinners (DOACs like apixaban, rivaroxaban) don't have the same issue, but always check with the prescriber.

Do I really need K2 if I eat fermented foods?

If you regularly eat natto, hard cheeses or grass fed butter you'll be getting some K2 from food. But most UK diets contain very little. Supplementing K2 is the most reliable way to know you're hitting useful levels, especially if you're taking D3.
