Vitamin K2 MK-7 100 mcg supplies vitamin K for normal bone and mineral metabolism at an economical serving cost.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality100

MK-7 is a favorable vitamin K form for the intended role. Its form quality does not establish superior health outcomes for every person.

Ingredient Transparency100

The vitamin K amount and MK-7 form are both disclosed. That makes it straightforward to compare the preparation and serving.

Value For Money100

The cost per serving is economical. The single-ingredient format makes that value comparison easy to interpret.

Customer Satisfaction93

Customer ratings are very positive across a particularly large review pool. They support satisfaction without establishing the expected bone or vascular outcomes.

Product Focus66

Vitamin K supports proteins involved in bone and mineral metabolism. More specific MK-7 bone and vascular findings are limited to particular preparations and groups, so broad benefits remain uncertain.

Vitamin K · 100 mcg

Vitamin K contributes toward ordinary nutrient needs. K2 forms do not establish superior general-health benefit or cardiovascular protection. Higher amounts do not establish extra benefit once intake is adequate.

How this product is rated for Everyday Health

Ingredient fit74

The known ingredients have a focused relationship to the retained nutritional functions. Some amounts fall below the comparison references or remain unresolved.
Goal fit
The retained ingredients closely match the comparison focus; this describes nutritional relevance rather than comprehensive health improvement.
Dose adequacy
The retained amounts provide partial or unresolved coverage of the saved comparison references, rather than demonstrating complete nutritional intake.

Pathways17

The strongest retained connection is bone and mineral metabolism. No function reaches the saved breadth threshold.
Depth
The strongest retained connection is bone and mineral metabolism, based on the known ingredient amounts.
Breadth
No function reaches the saved coverage threshold; this is distinct from proving that the ingredients are ineffective.

Evidence78

Vitamin K provides the strongest retained evidence. The supplied context supports nutritional availability or limited population-specific findings, without establishing broad health improvements beyond adequate intake.
Evidence strength
Vitamin K supplies the strongest retained evidence. Its supplied context limits expectations to nutritional or population-specific outcomes.
Studied preparation
The retained preparations match the saved criteria; no superiority of chemical form or delivery is established.

Formulation logic100

The supplied checks identify no configured conflict or missing required partner. The retained amount thresholds remain comparison references rather than treatment doses.
Partner coverage
The retained ingredients have no missing required partner under the saved criteria; this does not establish an added combination benefit.
Conflicts
No configured ingredient conflict was identified from the supplied amounts.
Effective doses
The retained amounts meet the saved minimum comparison threshold, which is not proof of a clinical effective dose.

Vitamin K · 100 mcg

MK-7 has limited evidence for selected arterial-stiffness improvements after sustained use in postmenopausal women, with some effects dependent on higher initial stiffness. This serving provides 100 mcg of MK-7, below the 180 mcg daily exposure in that trial. These findings do not establish cardiovascular-event prevention.

Vitamin K · 100 mcg

Vitamin K as MK-7 helps activate proteins involved in bone. The 100 mcg serving is below the 180 mcg daily preparation used in one three-year trial with favorable bone-density findings in postmenopausal women. Other supplied trial results were mixed, so this does not establish general fracture prevention. The formula's contribution is concentrated in bone-protein activation.
