Product analysis
D3 + K2 offers a focused vitamin combination with clearly disclosed amounts and forms. Its identified K2 form is a particular quality strength.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality65
The all-trans MK-7 form of vitamin K is a clear quality strength. Vitamin D is identified as D3, though a firm comparison of its quality is unavailable.
Ingredient Transparency100
Both vitamin amounts and forms are clearly stated. That makes it straightforward to compare the contents with other D and K supplements.
Value For Money57
The vitamin K portion offers favorable value within the serving price. Vitamin D’s value remains uncertain, so the complete combination is harder to compare.
Customer Satisfaction69
Customer feedback is positive, based on a modest number of ratings. Those experiences support satisfaction but do not establish health benefits.
Product Focus75
The two-vitamin formula appears well aligned with its intended uses. It stays reasonably focused without ingredients identified as unnecessary.

Vitamin K · 100 mcgVitamin D · 125 mcg
Vitamin K as MK-7 has limited support for arterial-stiffness measures in studied postmenopausal populations. Its serving amount provides partial comparison-range coverage rather than establishing the effects of sustained trial exposure. Vitamin D supplementation has not demonstrated general prevention of major cardiovascular events, and combining it with MK-7 does not establish an additional preventive benefit.

Vitamin D · 125 mcgVitamin K · 100 mcg
Vitamin D and vitamin K contribute to bone and mineral nutrition, with practical value when dietary intake is low. Their combination does not establish an extra benefit, and K2 has no demonstrated superiority in the supplied context. The substantial vitamin D amount does not demonstrate broader health improvements above adequacy or establish safety.

Ingredient fit84
The selected serving makes a partial nutrient contribution relative to the comparison amounts.
Goal fit
The relevant ingredients give this formula a focused connection to the supplied general-health roles.
Dose adequacy
The selected serving makes a partial nutrient contribution relative to the comparison amounts.
Pathways60
The strongest contribution concerns bone and mineral nutrition. Other meaningful coverage is limited to the named nutrient roles.
Depth
The strongest finding concerns bone and mineral nutrition, based on the relevant ingredients and their supplied amounts.
Breadth
Meaningful coverage extends to bone and mineral nutrition.
Evidence82
Vitamin D provides the leading evidence contribution. Nutritional functions and the preparation findings do not establish broad health improvements above adequate intake.

Vitamin D leads the evidence contribution; its nutrient role does not establish extra benefit above adequate intake.
Studied preparation
The included preparations meet the preparation criteria; this does not establish superiority of a particular form.
Formulation logic100
The included ingredients can contribute without a missing required partner, and no configured conflict was found. Their amounts pass the saved minimum contribution check.
Partner coverage
The included ingredients can contribute independently or have their required partners; no extra benefit from combining them is established.

Vitamin K · 100 mcgVitamin D · 125 mcg
Vitamin D helps calcium absorption and normal bone mineralization, particularly when vitamin D intake is inadequate. Vitamin K participates in bone-protein activation, but the saved result treated this preparation as unidentified despite the all-trans-MK-7 form description, so it did not receive the studied MK-7 preparation finding. The 125 mcg vitamin D serving does not imply extra fracture benefit. Calcium is absent, leaving mineral supply outside this formula’s contribution.
How this product is rated for Bone Health
Ingredient fit88
Vitamin D and vitamin K are relevant to bone-related functions, with a preparation uncertainty for vitamin K.
Goal fit
Vitamin D and vitamin K are relevant to bone-related functions, with a preparation uncertainty for vitamin K.
Dose adequacy
Vitamin D meets the saved amount reference, while vitamin K makes a smaller contribution under the unidentified-preparation finding.
Pathways60
Calcium absorption dominates; bone-protein activation contributes less and mineral supply is absent.
Depth
Calcium absorption and regulation are the best-covered aspect.
Breadth
Only calcium absorption meets the saved coverage criterion; bone-protein activation remains partial.
Evidence82
Vitamin D supplies the strongest saved evidence contribution; vitamin K preparation matching remains unresolved.
Evidence strength
Vitamin D supplies the strongest saved evidence contribution; this does not establish fracture prevention.
Studied preparation
Vitamin D matches the studied-preparation finding; vitamin K was treated as unidentified.
Formulation logic90
The saved findings identify no matched ingredient conflicts. Vitamin D lacks a qualifying calcium partner.
Partner coverage
Vitamin D lacks a qualifying calcium partner in the saved findings.
Conflicts
No evaluated ingredient conflict was found; this is not a general safety conclusion.
Effective doses
All ingredients included in this rule meet the saved amount threshold; that threshold is not a proven effective dose.

Vitamin K · 100 mcgVitamin D · 125 mcg
Vitamin D helps preserve muscle function when deficiency causes weakness; supplementation has not shown the same benefit in vitamin D-replete adults. Vitamin K vascular findings apply to identified MenaQ7 in postmenopausal women; unspecified vitamin K does not establish the same benefit.

Vitamin K · 100 mcgVitamin D · 125 mcg
MK-7 has limited support for selected arterial-stiffness measures in postmenopausal women, rather than established prevention of cardiovascular events.
