Why MK-7 — and why "all-trans" matters
Almost every K2 buying decision comes down to one thing: choose MK-7, not MK-4. MK-7 has a long half-life, so a single 90–200 mcg daily dose reaches and holds useful blood levels; MK-4 is cleared within hours and only worked in trials at a pharmaceutical 45 mg a day (taken as 15 mg three times daily). That's why the standalone supplements worth buying are MK-7. For the full pharmacology, see MK-7 vs MK-4.
The quality wrinkle is that MK-7 comes in an active all-trans form and a much less active cis form that contaminates cheap synthetic material. Branded, fermentation-derived ingredients like MenaQ7 are tested to guarantee all-trans content — which is why our top pick uses one. A label that says "all-trans" or names its ingredient brand is a genuine quality signal; a bargain MK-7 with neither is a gamble.
What to look for
- MK-7, not MK-4 — the practical form for daily supplementation.
- All-trans, ideally branded — look for "all-trans" or a named ingredient (MenaQ7). This is the single biggest quality differentiator.
- A trial-anchored dose — 90–200 mcg MK-7. 100 mcg is the sweet spot; 300 mcg sits at the upper studied range.
- Soy-free if you're allergic — natto-derived MK-7 can carry trace soy; chickpea-fermented options (like our top pick) avoid it.
- Pure MK-7 vs a blend — a standalone MK-7 is cleanest. Some products add K1 — the form in leafy greens your liver uses for blood clotting — plus a little MK-4 on top; that's fine if you want fuller vitamin-K coverage, but the MK-7 is what does the bone-and-artery work.
What we don't recommend
- Unbranded bargain MK-7 with no all-trans claim — you can't tell how much is the inactive cis form.
- Low-dose MK-4-only products — MK-4 doesn't accumulate at supplement doses; you'd need a pharmaceutical 45 mg regimen for the effect its trials showed.
- Anything promising to "clean out" or "reverse" arterial calcification — the recent hard-endpoint trials were negative. K2 supports the calcium-routing system; it doesn't dissolve existing plaque. See the honest evidence on the MK-7 vs MK-4 page.
- Starting K2 while on warfarin without your doctor — vitamin K opposes warfarin, and consistency of intake matters. This is a conversation with your prescriber, not a self-serve add-on.

Frequently Asked Questions
What is the best vitamin K2 supplement?
For most people the best vitamin K2 is a standalone all-trans MK-7 at the clinical 100 mcg dose. Our top pick is NOW Supplements MK-7 100 mcg, which uses the branded MenaQ7 ingredient (all-trans) at about $0.36 a day. For the lowest cost, Nutricost MK-7 100 mcg is about $0.11 a day. Choose MK-7 over MK-4, and look for an all-trans label.
How much vitamin K2 should I take per day?
A trial-anchored MK-7 dose is 90–200 mcg per day; the 3-year trials used 180 mcg. There is no established upper limit for vitamin K. Take it with a fatty meal. The one hard rule: if you take warfarin or another vitamin K antagonist, do not start K2 without your physician. See our MK-7 vs MK-4 guide for the full dosing breakdown.
What does "all-trans" MK-7 mean on a label?
MK-7 exists as an active all-trans form and a much less active cis form that can contaminate cheap synthetic material. All-trans is the form used in the clinical trials and the one you want. Branded, fermentation-derived ingredients like MenaQ7 are tested to guarantee all-trans content; a label that says "all-trans" or names a branded ingredient is a good quality signal.
