How does Vitamin K2 + D3, 120 Capsules score?
Detailed score breakdown and key findings from our analysis of 50 reviews across 1 source.
Pros
- +K2 supplied as MK-7 — the superior form for directing calcium away from arteries and into bone tissue
- +5,000 IU D3 is a proper therapeutic dose for correcting deficiency, not a token maintenance amount
- +Multiple reviewers report measurable improvements in vitamin D blood levels after switching to this product
- +Small capsule size and no aftertaste — frequently mentioned as making daily use easy
- +Clean excipient list with no artificial dyes or unnecessary fillers; gluten and soy free
Cons
- -No independent third-party testing (NSF, USP, or equivalent) — the 'lab tested' label claim is manufacturer self-testing only
- -5,000 IU daily is above typical maintenance doses — not suitable for self-prescribing without a blood test first
- -K2 is contraindicated with warfarin and other anticoagulants, which the label warns about but users often overlook
- -Not vegan — D3 is almost certainly lanolin-derived despite the plant-based capsule shell
Best For
Watch Out
- !Test your D3 levels before and during use — 5,000 IU daily can push levels too high if you're not actually deficient
- !Anyone on anticoagulants (warfarin, heparin) should not take K2 without medical supervision
- !No independent certification means you're trusting the manufacturer's own quality claims
