About this product

MK-7 and vitamin D3 form a coherent calcium-management pair, while vitamin K1 adds normal clotting support. Softgel delivery suits all three fat-soluble nutrients.

The MK-7 amount is practical, but the vitamin D3 amount is far above typical daily maintenance. No calcium or magnesium is included, so the formula focuses on regulators rather than structural bone material.

The product fits only adults with a clinician-supported reason for very high vitamin D3. It should not be treated as an ordinary daily D3 and K supplement.

Who is it for
  • Adults with a monitored high-vitamin-D plan
  • Users wanting MK-7 in a softgel
  • People needing combined K1 and K2
Best for
  • Clinician-guided vitamin D repletion
  • Calcium-regulation cofactors
  • Focused bone-support protocols

Pros

  • Meaningful MK-7 amount
  • Softgel supports absorption
  • K1 and K2 are separately disclosed

Cons

  • Vitamin D3 is far above routine maintenance
  • No structural minerals
  • Generic MK-7 source

Warnings

  • Very high vitamin D3 can cause excessive blood calcium and kidney problems with prolonged unsupervised use
  • Use regularly only with appropriate vitamin D and calcium monitoring
  • K1 and MK-7 can oppose warfarin and related vitamin K antagonist medicines
  • Account for vitamin D from every other supplement

Product analysis

70 out of 100
A well-delivered K1, MK-7, and D3 formula whose very high vitamin D amount requires documented need and monitoring.

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

Nutrient quality75

Vitamin D3, vitamin K1, and menaquinone-7 are clearly identified usable forms, and vitamin K is meaningful, while vitamin D3 is far above a routine maintenance amount. Vitamin D3 exceeds the adult upper limit and may raise calcium levels with sustained use, while the focused formula avoids low-value active extras.

Ingredient transparency81

Specific amounts are listed for every supplied active ingredient. No proprietary blend hides active doses, while capsule, softgel, or tablet excipients are not included in the supplied details.

Customer satisfaction69

The supplied aggregate satisfaction metric is very strong, and the feedback volume is sufficient for a reasonably stable aggregate metric. No review excerpts were provided, so recurring complaints and purpose-specific experiences cannot be checked.

Value for money48

Useful forms are offset by a vitamin D amount that is too aggressive for routine use. The serving is moderately costly and supplies more vitamin D than most users need, while the formula avoids unnecessary extras.

Vitamin K2 as MK-7 and vitamin D3 create a strong calcium-management pairing relevant to arterial health. The 90 mcg MK-7 amount is meaningful, but the 250 mcg vitamin D amount is unusually high for routine daily use.

Added vitamin K1 supports clotting rather than broadening cardiovascular mechanisms substantially. Long-term use of the high vitamin D3 amount can raise calcium levels, while both K1 and MK-7 directly oppose warfarin and related vitamin K antagonists.

Vitamin D3 and MK-7 support calcium absorption and bone-directed calcium proteins, giving the formula strong regulator coverage. It does not supply calcium, magnesium, or protein-matrix material.

The 10,000 IU D3 amount is too high for routine long-term use without documented need and monitoring because it may cause excessive calcium and kidney problems. MK-7 can also oppose warfarin and other vitamin-K-antagonist anticoagulants.

Vitamin K · 90 mcgVitamin D · 250 mcg

Vitamin D3 and MK-7 form a coherent calcium-management pair with plausible relevance to arterial health. Vitamin K1 adds clotting support but does not strengthen the arterial rationale as much as more K2 would.

The softgel supports absorption and the 90 mcg MK-7 amount is meaningful, while 250 mcg vitamin D3 is far above the usual adult daily upper intake level. The high vitamin D3 amount can raise calcium levels with prolonged unsupervised use, and both K forms can alter warfarin response.

A- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB+ Value

The combination provides a clinically aligned MK-7 amount alongside clearly separated vitamin K1 and vitamin D3. Softgel delivery supports absorption of these fat-soluble vitamins. The dose and cost are well balanced, although no branded or all-trans MK-7 source is named.
