Vitamin D3 and vitamin K2 form a logical pair for calcium absorption and placement. Both forms and amounts are clearly stated, making the compact formula easy to assess.
The K2 is MK-4, which is shorter acting than MK-7 and is supplied at a modest amount. A dry capsule offers no stated fat-based carrier for either fat-soluble vitamin.
The product fits basic maintenance use for people who specifically want a small D3 and MK-4 combination. It is less suitable for shoppers seeking a long-lasting MK-7 formula or high-depth bone support.
Lanolin-derived vitamin D3 and menaquinone-4 are usable forms, and vitamin D3 is meaningful for maintenance, while the menaquinone-4 amount is modest. Neither vitamin amount appears unnecessarily aggressive, while the small ascorbyl palmitate addition does not materially dilute the focused formula.
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.
The supplied aggregate satisfaction metric is very strong, and the large amount of aggregate feedback makes the metric highly stable. No review excerpts were provided, so recurring complaints and purpose-specific experiences cannot be checked.
Useful vitamin D3 and vitamin K2 at a low serving cost support strong value. Each capsule provides the full active serving with little burden, while the formula avoids meaningful low-value extras.
| Ingredient | Amount per serving |
|---|---|
Vitamin C (Ascorbyl Palmitate) | 3 mg |
Vitamin D3 (Lanolin) | 25 mcg |
Vitamin K2 (Menaquinone-4) | 45 mcg |
Menaquinone-4 is clearly disclosed, but it is shorter acting than MK-7 and generally requires different dosing. The low serving cost and added vitamin D3 are useful, yet no MK-7 is present and the dry capsule lacks stated fat-meal guidance. Vitamin K2 can oppose warfarin and related vitamin K antagonist medicines, so users of these drugs need consistent intake and prescriber guidance.
