87 Performance

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

Natural Factors

Moderate vitamin D3 with more MK-7 creates a better-balanced maintenance formula than the original’s aggressive vitamin D amount. Phosphorus and calcium are absent, and duplicate K2 source entries create minor label ambiguity.

84 Performance

D3 + K2

Nature Made

All-trans MK-7 and vitamin D3 use clearly defined forms in a concise formula with twice the original’s K2. Vitamin D remains high, phosphorus and calcium are omitted, and the short supply weakens value.

89 Performance

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

NOW

Branded MK-7 at a higher amount pairs with the same vitamin D3 dose in a focused formula. High vitamin D remains the main limitation, while phosphorus and calcium are absent and the dry capsule has no stated fat-intake guidance.

86 Budget

Liquid D-3 & MK-7

NOW

A lower vitamin D3 amount paired with more MK-7 provides a more balanced bone-support ratio at much better serving value. Phosphorus and calcium are absent, while vitamin K requires consistent clinician-directed intake with warfarin-type medicines.

86 Budget

Vitamin K2 100 mcg + Vitamin D3 125 mcg

Nutricost

The same vitamin D3 amount with twice as much MK-7 provides a close, much lower-cost alternative. Vitamin D remains concentrated, phosphorus and calcium are absent, and the MK-7 source plus inactive ingredients are not supplied.

86 Budget

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

NaturesPlus

A lower vitamin D3 amount and higher MK-7 provide a more restrained, economical bone-support option. Phosphorus and calcium are absent, the dry tablet lacks a lipid carrier, and vitamin K may conflict with warfarin-type medicines.

86 Value

Natural Vitamin K2 MK-7 with MenaQ7 100 mcg

Doctor's Best

A focused MenaQ7 formula removes the original’s aggressive vitamin D exposure while retaining meaningful K2 at good value. It omits vitamin D, phosphorus, and calcium, and vitamin K is unsuitable for unsupervised use with warfarin-type medicines.

88 Value

Vitamin K2 MK-7 100 mcg

Nutricost

A long, economical supply provides meaningful MK-7 without adding more high-dose vitamin D. Phosphorus, calcium, and vitamin D are absent, while the dry capsule lacks a stated lipid carrier and source details.

87 Value

Boneology Superior Calcium Form 167 mg

Swanson Premium Brand

Hydroxyapatite supplies clearly listed calcium and phosphorus at strong serving value for bone-mineral support. Vitamin D3 and K2 are absent, so it complements the original’s mineral gap rather than replacing its vitamin profile.
