Detailed score breakdown and key findings from our analysis of 50 reviews across 1 source.
Pros
- +240-capsule bottle makes this one of the cheapest per-serving K2 MK-7 options — repeatedly highlighted by reviewers as the primary buying reason
- +MK-7 form has a long half-life (~72 hours), making once-daily dosing genuinely effective rather than a convenience compromise
- +Small softgels with no taste or aftertaste — multiple reviewers with swallowing difficulties specifically flag this
- +Minimal ingredient list: MK-7, sunflower oil, gelatin capsule — no unnecessary fillers beyond the caramel capsule colouring
- +Widely reported as IBS- and stomach-friendly when taken with food containing fat
Cons
- -Gelatin capsules — not suitable for vegans or vegetarians
- -Caramel colouring in the capsule shell uses ammonia-based processing; flagged by at least one reviewer with multiple chemical sensitivities
- -One reviewer notes the brand does not publish isomer data — unclear what percentage is all-trans MK-7 (the active form) versus cis
- -Rare reports of heart palpitations and anxiety, particularly when combined with high-dose vitamin D3
Best For
Watch Out
- !Not vegan — gelatin capsules
- !Caramel colouring may be problematic for people with multiple chemical sensitivities or MCAS

- !Third-party testing is listed on the label but not confirmed in product specs — verify independently if certification matters to you
