Product analysis
Vitamin D3 25 mcg (1000 IU) & K2 120 mcg may help fill nutrient gaps relevant to normal bone and mineral health.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality72
The K2 is identified as MK-7, a favorable vitamin K form. D3 is also named, but its quality remains uncertain.
Ingredient Transparency80
The vitamin amounts and forms are stated, making the main ingredients easy to compare. The relative contributions of the declared vitamin K sources are undisclosed.
Value For Money72
The serving price is favorable when considered as a source of MK-7 vitamin K. Vitamin D value remains uncertain, so the favorable comparison does not establish value for both nutrients.
Customer Satisfaction90
Customer ratings are very positive. Thousands of responses give the favorable feedback a broad base.
Product Focus74
The clearest purpose is nutritional support for normal bone and mineral functions. The K2 serving is below one arterial-stiffness comparison, and taking D3 with K2 does not establish extra benefits from the combination.

Vitamin K · 120 mcgVitamin D · 25 mcg
Vitamin D helps calcium absorption and supports mineralization when intake or vitamin D status is low. MK-7 supports bone-protein activation, with limited and mixed bone-density findings in postmenopausal women. The saved nutrient contributions do not establish routine fracture prevention.
How this product is rated for Bone Health
Ingredient fit79
The formula supplies several bone-related nutrients, with much of its support tied to normal nutrition. The included nutrients provide mixed amount comparisons; several reach their saved references while others provide partial contributions.
Goal fit
The formula supplies several bone-related nutrients, with much of its support tied to normal nutrition.
Dose adequacy
The included nutrients provide mixed amount comparisons; several reach their saved references while others provide partial contributions.
Pathways67
The saved findings concentrate on calcium absorption, bone-protein activation.
Depth
The saved findings concentrate on calcium absorption, bone-protein activation.
Breadth
These areas reach the saved coverage threshold.
Evidence98
Vitamin K supplies the strongest saved evidence. Normal nutrient roles and limited bone-density findings do not establish routine fracture prevention.
Evidence strength
Vitamin K supplies the strongest saved evidence; its retained contribution does not establish fracture prevention.
Studied preparation
The included preparations meet the saved preparation criterion; this does not prove superior absorption or fracture outcomes.
Formulation logic92
Vitamin D retains an individual contribution, but calcium is absent or below the required partner amount. No configured conflict was identified.
Partner coverage
Vitamin D retains an individual contribution, but calcium is absent or below the required partner amount.
Conflicts
No configured conflict was identified in the supplied findings.
Effective doses
All included ingredients reach the saved minimum amount criterion; that criterion is not a proven clinical dose.

Vitamin K · 120 mcgVitamin D · 25 mcg
MK-7 vitamin K has limited support for arterial stiffness, chiefly from selected postmenopausal populations; this does not establish prevention of heart events.
How this product is rated for Heart Health
Ingredient fit76
The relevant nutrients contribute to distinct nutritional or vascular roles, with preparation and amount limits shaping their contribution.
Goal fit
The relevant ingredients give this formula a clear focus on the supported heart-health roles.
Dose adequacy
The credited amounts provide partial coverage of the saved comparison anchors, rather than establishing a complete daily regimen.
Pathways44
The strongest finding concerns MK-7 and arterial stiffness; the pathway label does not establish reversal of arterial calcification.
Depth
The strongest finding concerns MK-7 and arterial stiffness; the pathway label does not establish reversal of arterial calcification.
Breadth
Only one area reaches the saved coverage benchmark, so support is concentrated rather than broad.
Evidence77
MK-7 leads the evidence finding, with limited arterial-stiffness support in selected populations.
Evidence strength
MK-7 leads the evidence finding, with limited arterial-stiffness support in selected populations.
Studied preparation
The saved finding recognizes the credited preparations; this does not make different forms interchangeable or establish a daily study regimen.
Formulation logic100
The counted ingredients have their required partners, and no configured conflict was identified.
Partner coverage
No required partner is missing among the credited ingredients; this does not establish added benefit from combining them.
Conflicts
No configured ingredient conflict was matched in the supplied facts.
Effective doses
The counted ingredients meet the saved amount benchmark, which is a comparison convention rather than a proven minimum effective dose.
Impact

Vitamin K · 120 mcgVitamin D · 25 mcg
Vitamin D helps preserve muscle function when deficiency is corrected. Vitamin K’s arterial-flexibility findings concern identified MenaQ7 in postmenopausal women; generic MK-7 is not automatically equivalent.
How this product is rated for Longevity
Ingredient fit76
The saved findings count a range of ingredients and compare their amounts with reference amounts. Ingredient presence and amount alone do not establish anti-aging effects.
Goal fit
The counted ingredients form a focused mixture, although the product is linked to several health purposes.
Dose adequacy
The counted amounts provide partial coverage of the saved references; that comparison does not establish a clinically effective anti-aging dose.
Pathways13
The strongest saved coverage is arterial calcification control. Mechanistic coverage does not demonstrate lifespan extension.
Depth
The strongest saved coverage concerns arterial calcification control, a mechanistic finding rather than evidence of slower human aging.
Breadth
No pathway reaches the saved coverage threshold.
Evidence74
Vitamin D leads this finding; functional benefit is most relevant to deficiency correction, not additional benefit in replete adults.
Evidence strength
Vitamin D leads this finding; functional benefit is most relevant to deficiency correction, not additional benefit in replete adults.
Studied preparation
The saved preparation check remains incomplete for Vitamin K. Clinical preparation equivalence cannot be assumed.
Formulation logic100
The saved findings show partner coverage and no matched ingredient conflicts. Some amount or preparation limits may still restrict practical relevance.
Partner coverage
The counted ingredients have their required partners or work independently under the saved findings; this does not demonstrate added benefit from combining them.
Conflicts
No ingredient conflict was matched in the supplied findings.
Effective doses
All counted ingredients pass the saved minimum amount threshold, which does not establish a proven anti-aging dose.

Vitamin D · 25 mcgVitamin K · 120 mcg
Vitamin D contributes to bone and mineral nutrition, and vitamin K supplies a nutrient involved in normal bone metabolism. Their usefulness is primarily in filling dietary gaps. The saved comparison gives a larger relative amount contribution to vitamin K, without establishing extra benefit from taking the two together or superiority of a particular vitamin K form.

Vitamin K · 120 mcgVitamin D · 25 mcg
Vitamin K as MK-7 has limited support for selected arterial-stiffness measures, mainly from a long trial in postmenopausal women. The 120 mcg serving is below the 180 mcg daily exposure highlighted in that trial, and receives a partial saved amount contribution. This does not establish prevention or reversal of arterial calcification or fewer cardiovascular events. Vitamin D is also present, but routine cardiovascular prevention and additional D3–K2 benefit are not established.
How this product is rated for Cardiovascular Support
Ingredient fit76
The explicitly identified MK-7 form supplies the main cardiovascular connection; both declared nutrients receive partial amount contributions.
Goal fit

Pathways44
The saved findings emphasize the arterial-calcification category, while the supporting clinical evidence concerns selected arterial-stiffness measures.
Depth
The arterial-calcification category is strongest in the saved findings; that label does not prove prevention or reversal of calcification.
Breadth
Only the arterial-calcification category reaches substantial saved coverage.
Evidence69
MK-7 leads the evidence findings, with limited population-specific arterial-stiffness results.
Evidence strength
MK-7 leads the saved finding; selected stiffness measures do not establish fewer cardiovascular events.
