AI assessment of the formula, label and price. How scoring works
Nutrient Quality66
Vitamin K is supplied as MK-7, a favorable form for the intended bone-related use. Vitamin D3 is named, but its comparative form quality cannot be established from the available information.
Ingredient Transparency100
Both vitamin amounts and forms are stated clearly. You can compare the serving directly with other vitamin D and K combinations.
Value For Money66
The MK-7 contribution offers favorable value at the serving cost. Value for the vitamin D contribution remains uncertain without a usable comparison.
Customer Satisfaction91
Customer ratings are very positive across a large review base. That provides a broad picture of satisfaction, without proving the claimed health benefits.
Product Focus76
The two vitamins have related roles in bone and mineral health, without an established extra benefit from combining them. The 125 mcg vitamin D serving exceeds the nutritional reference, so the large amount should not be assumed to bring extra benefit or establish safety.
