Product analysis
MK-7 Vitamin K-2 100 mcg may support selected measures of bone health, with limited evidence from postmenopausal women. The findings do not establish general fracture prevention or longer life.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality100
Vitamin K is clearly identified as MK-7. That identifies the preparation without establishing superior clinical outcomes.
Ingredient Transparency100
The vitamin K amount and MK-7 form are disclosed. Those details make the serving straightforward to compare.
Value For Money100
The low cost per serving supports good value for MK-7. The clearly identified preparation makes comparisons with similar supplements straightforward.
Customer Satisfaction94
Customer feedback is very positive across tens of thousands of ratings. The extensive review base gives a well-established picture of satisfaction.
Product Focus70
The clearest support concerns selected bone and blood-vessel measures in postmenopausal women. The serving is below the principal long-term study amount, and those findings do not establish fewer fractures, cardiovascular events or longer life.
