MenaQ7 MK-7 — standalone K2 when D3 is already in another bottle

4.7
(8,600 community reviews)

NOW’s soy-free MenaQ7 MK-7 capsule is the cheap standalone K2 next to Thorne D3+K2. Use it when your D3 is already a NOW 5,000 IU softgel or you want MK-7 without buying another combo. 100 mcg is a maintenance dose — not the 45 mg MK-4 protocol from Japanese fracture trials.

How It Works

K2 carboxylates osteocalcin and matrix Gla protein so calcium is more likely to go to bone than artery wall. Rotterdam-style epidemiology is the popular citation. Outcomes for low-dose MK-7 in already-sufficient people are modest. Warfarin and K2 do not mix without a clinician.

1

MK-7 Once Daily

100 mcg menaquinone-7. Longer half-life than MK-4, so one capsule with a fat-containing meal is the usual pattern.

2

Pair With D3, Do Not Double Blindly

If you already take Thorne D3/K2, you do not need this bottle too. This SKU is for D3-only users.

3

MenaQ7 Source

Trademarked MK-7. Soy-free. Not a blood-thinner substitute and not a reason to skip warfarin advice.

What You'll Experience

No Subjective Feel

Months

You will not ‘feel’ K2. The win is the pairing with D3, not mood on day three.

Labs

Year 1

Bone and calcium-score changes are slow. Recheck 25(OH)D; do not chase ucOC at home.

Benefits

Cheap MK-7

Moderate Evidence

60 capsules at a NOW price when you already bought D3 separately.

Once-Daily Format

Moderate Evidence

MK-7 beats three-times-daily MK-4 for people who will not remember lunch.

Risks & Considerations

Anticoagulants

high risk

Vitamin K interacts with warfarin and similar drugs. That is a clinician conversation, not a Reddit stack.

Not a Calcium Dump Fix

medium risk

K2 will not un-calcify arteries you already have. It is preventive framing.

Mostly Positive

NOW MK-7 is a frequent ‘just add this to D3’ pick. Smart comments all say skip it if the combo bottle already has K2.
