About this product

Bone and mineral nutrition is the most coherent use for the main combination. Vitamin D supports calcium absorption when intake or status is low, while MK-7 helps activate proteins involved in bone health. The 125 mcg vitamin D serving does not establish greater benefit simply because it is high.

MK-7 is clearly identified at 90 mcg, although its trans or all-trans composition is not specified. Its bone and arterial-stiffness findings have limits and do not establish broad protection from the D3 and K2 combination. Zinc at 30 mg adds normal immune and skin-related nutritional support, with hair and testosterone relevance mainly tied to inadequate zinc intake.

The main nutrient amounts are easy to compare, and value appears reasonable for MK-7 and zinc. The zinc chelate is broadly named, copper information is unavailable, and the whole-food blend does not identify its individual contents. Those gaps leave the mineral balance and the blend's added contribution uncertain.

Who is it for
  • Adults with a reviewed need for higher vitamin D intake
  • People seeking MK-7 with zinc and willing to check their full supplement intake
Best for
  • Bone and mineral nutrition when intake or status is low
  • A clearly quantified MK-7 contribution

Pros

  • States the MK-7 subtype and amount
  • Clearly quantifies the main three nutrients
  • Reasonable value for the zinc and MK-7 contributions

Cons

  • Whole-food blend components are undisclosed
  • Copper information is unavailable alongside 30 mg zinc
  • Zinc chelate carrier and MK-7 isomer details are incomplete
  • Additional heart or hormone benefits from the combination remain unestablished

Warnings

  • The 125 mcg vitamin D serving warrants review before ongoing daily use, particularly if another supplement also contains vitamin D.
  • Adding separate zinc to the 30 mg already supplied can make total zinc intake excessive.

Product analysis

60 out of 100

Vitamin D K2 & Zinc supplies nutrients for normal immune, bone and mineral functions, with benefits most relevant when intake is inadequate. Its unidentified herbal blend makes that part of the formula difficult to judge.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality53

MK-7 is the clearest strength among the nutrient forms. Zinc has less convincing form-quality support, while the vitamin D comparison and herbal blend details remain uncertain.

Ingredient Transparency73

The nutrient amounts and vitamin and zinc forms are disclosed. The herbal blend contents and form are undisclosed, so its total amount does not show what each plant contributes.

Value For Money62

MK-7 offers favorable value at the full serving cost, with zinc providing more moderate value. Vitamin D value remains uncertain, so the combination cannot be judged equally across all its nutrients.

Customer Satisfaction81

Customer satisfaction is very positive across several hundred ratings. The response volume provides a useful view of buyer experience without establishing health benefits.

Product Focus35

Normal immune and bone functions provide the clearest nutritional purpose. The wider goals have more conditional support, and the unidentified herbal blend prevents a complete view of the formula.

Zinc and vitamin D support normal immune-cell function. Both receive full recognition for their declared amounts in the saved findings, but this does not establish infection prevention or greater benefit from the higher vitamin D amount. Elderberry presence remains unresolved in the supplied inventory, so it cannot support a product-specific contribution.

How this product is rated for Immunity

Ingredient fit83

The formula’s immune connection comes from its relevant nutrients, with amount and focus limitations reflected below.
Goal fit

Vitamin K · 90 mcgVitamin D · 125 mcg

Vitamin D K2 & Zinc provides 125 mcg vitamin D and 90 mcg vitamin K as MK-7. Those nutrients link mainly to calcium buildup in artery walls rather than a broad set of cardiovascular markers; the added zinc has no clear marker link in the supplied context. These ingredient links don't establish heart-event prevention.

How this product is rated for Cardiovascular Support

Ingredient fit71

Vitamin D and K2 are the two cardiovascular-linked actives, both with declared amounts. Zinc doesn't add a clear marker link, and the product is connected to several other goals.
Goal fit
Vitamin D and K2 connect to cardiovascular markers; zinc and the product's other goal links dilute the focus.
Dose adequacy
Vitamin D at 125 mcg and vitamin K at 90 mcg have declared amounts that support meaningful dose alignment.

Pathways16

Calcium buildup in artery walls is the clearest route, with moderate rather than broad coverage. Other cardiovascular pathways have little support from the disclosed actives.
Depth
Calcium buildup in artery walls is the clearest route, but coverage remains moderate.
Breadth
No second pathway has enough support to add meaningful marker coverage.

Evidence69

Vitamin K provides the clearest supplied evidence link, while vitamin D also contributes. The evidence concerns markers, not cardiovascular events.
Evidence strength
Vitamin K has the clearest supplied effective-dose evidence among the credited ingredients.
Studied preparation

Vitamin K · 90 mcgVitamin D · 125 mcgZinc · 30 mg

Vitamin D supports calcium absorption and deficiency-related mineralization, while MK-7 helps activate bone proteins. MK-7 bone-density findings are limited to specific postmenopausal populations and do not establish fracture prevention. The 125 mcg vitamin D serving does not establish extra benefit over nutritional adequacy. Zinc is included in the saved findings, but the supplied evidence does not establish routine additional adult bone-density or fracture benefit from zinc supplementation.

How this product is rated for Bone Health

Ingredient fit85

The formula includes nutrients connected to bone health, with differing serving contributions and preparation-specific limitations.
Goal fit
The included ingredients are focused on bone-related roles, although the product is linked to several goals.
Dose adequacy
The declared serving amounts provide uneven contributions relative to the supplied comparison amounts; unknown amounts cannot establish an additional contribution.

Pathways100

The saved findings emphasize calcium absorption and regulation and show broader coverage through calcium handling, bone-protein activation and collagen matrix formation. Coverage describes ingredient roles, not demonstrated clinical improvement.
Depth
The strongest saved finding concerns calcium absorption and regulation; this describes ingredient roles rather than a measured clinical outcome.
Breadth
The saved findings reach the comparison level for calcium handling, bone-protein activation and collagen matrix formation.

87 Performance

Vitamin D3 25 mcg (1000 IU) & K2 120 mcg

Natural Factors
Moderate vitamin D3 with MK-7 provides a more balanced maintenance dose than the original concentrated vitamin D3 amount. Zinc is omitted and duplicate K2 source entries create minor ambiguity, but the two-vitamin profile is well aligned with bone and cardiovascular support.
83 Performance

Zinc 30 mg

Nature's Life
Zinc picolinate with copper improves mineral balance compared with the original high zinc dose without copper. It does not provide vitamin D3 or MK-7, and repeated copper entries make the total less clear than it should be.
89 Performance

Mega D-3 5000 IU & MK-7 180 mcg

NOW
Branded MK-7 and clearly stated vitamin D3 provide strong active quality and label clarity. The vitamin D amount remains concentrated and zinc is absent, so it improves K2 focus without solving the original's high-dose concern or replacing its full profile.
84 Budget

Zinc Gluconate 30 mg

Swanson
Zinc gluconate matches the original zinc amount at a much lower serving cost. It omits vitamin D3 and MK-7, and sustained use without copper may impair mineral balance, so it is a narrow substitute rather than a complete replacement.
88 Budget

Vitamin K2 MK-7 100 mcg

Nutricost
A clearly meaningful MK-7 amount targets the original's vitamin K role at a much lower serving cost. Vitamin D3 and zinc are omitted, while the MK-7 source and inactive ingredients are not supplied.
85 Budget

Zinc 30 mg

Nature Made
Zinc gluconate supplies the same substantial zinc amount very inexpensively. The focused tablet leaves out vitamin D3 and MK-7, and prolonged daily use without copper may gradually disturb mineral balance.
86 Value

Vitamin K2 100 mcg + Vitamin D3 125 mcg

Nutricost
MK-7 and vitamin D3 closely match two of the original's three actives at much lower serving cost. Zinc is omitted and the vitamin D3 amount is still concentrated, but the softgel provides a focused value option.
85 Value

OptiZinc

Source Naturals
Zinc methionine with added copper offers better mineral balance and strong absorption potential at low serving cost. The copper amount is small relative to zinc and the formula omits vitamin D3 and MK-7, so it works as the zinc portion of the original rather than a full substitute.
86 Value

Vitamins D3 2500 IU (62.5 mcg) & K2 120 mcg

NaturesPlus
MK-7 and a more moderate vitamin D3 amount improve dose balance while preserving the original's two vitamin actives at lower cost. The dry tablet lacks a lipid carrier and zinc is absent, but the formula offers a practical D3-and-K2 value trade-off.
