Vitamin K2
MK-7 (Menaquinone-7) — typical dose 180 mcg
We don’t sell Vitamin K2. Whether you actually need it — and at what dose — depends on your bloodwork. Get your analysis to find out.
What it does
Vitamin K2 MK-7 is the long-acting form that ensures calcium goes where it belongs: into your bones and teeth, not your arteries. It activates osteocalcin (bone protein) and matrix GLA protein (prevents arterial calcification). MK-7 has a longer half-life than MK-4, meaning one daily dose maintains consistent blood levels.
Key benefits
- Bone mineralisation
- Arterial health
- Dental health
- Synergistic with D3
The evidence
Rotterdam Study showed 57% reduced risk of heart disease with adequate K2 intake. MK-7 form has superior bioavailability and longer half-life vs MK-4.
Where to buy
If your analysis calls for Vitamin K2, this is the quality, single-ingredient version we’d reach for:
Doctor's Best — Natural Vitamin K2 MK-7 (MenaQ7), Veggie Caps (100 mcg MK-7 / cap)Panel-verified single-ingredient MK-7 (MenaQ7) from a reference brand. At 100 mcg it sits just under our 180 mcg note — no clean reference-brand product lands exactly at 180.
We may earn a small referral fee if you buy through this link — it never changes our pick. We hold no inventory and have no house brand.
Important
If you take warfarin or other blood thinners, consult your doctor before supplementing K2 — it affects clotting factor synthesis.
