AI assessment of the formula, label and price. How scoring works
Nutrient Quality70
The vitamin K is supplied as a well-supported MK-7 form. Vitamin D3 is also named, although its relative quality cannot be compared fully here.
Ingredient Transparency100
Both vitamin amounts and forms are disclosed. That makes the combination straightforward to compare with other D and K supplements.
Value For Money70
The vitamin K contribution compares favorably on serving cost. Vitamin D value cannot be judged confidently, so the favorable conclusion applies chiefly to vitamin K.
Customer Satisfaction96
Customer ratings are very favorable across a very large review base. They provide extensive satisfaction feedback without proving bone or cardiovascular outcomes.
Product Focus80
The clearest purpose is supporting mineral nutrition and normal bone maintenance. MK-7 also has limited findings for arterial stiffness, which do not establish fewer cardiovascular events or longer life.
