One capsule provides 4,000 IU vitamin D3, 100 mcg vitamin K2 as MK-7, 80 mg vitamin C, and 120 mg calcium. The purpose is obvious at a glance: a once-daily routine for bone, muscle, and immune support.

What This Formula Is Built For
Bone support
Vitamin D helps the body absorb calcium, and both nutrients have established roles in bone health. This formula states the amount of each instead of treating them as one interchangeable number.[1][3]
Muscle function
Vitamin D contributes to normal muscle function. A supplement supports nutritional intake; it does not replace movement, protein, or medical evaluation for weakness.[1]
Immune support
Vitamins D and C have established roles in immune function, which supports a straightforward daily-wellness story without promising illness prevention.[1][4]
K2 as MK-7
Vitamin K is required for proteins involved in blood clotting and bone metabolism. This formula uses the menaquinone-7 form and clearly states 100 mcg.[2]
Food-time routine
The current label directs one capsule daily with food and water, making the routine easy to attach to breakfast or another consistent meal.
Sixty servings
One capsule is one complete serving, so a 60-capsule bottle provides 60 label servings.
What the research says
Established nutrient roles. A high-D serving still needs context.
Vitamin D supports calcium absorption and has established roles in bone, muscle, and immune function. Vitamin K participates in proteins involved in clotting and bone metabolism, while calcium is a principal structural component of bone.[1][2][3]
The labeled serving provides 4,000 IU (100 mcg) vitamin D3—the NIH adult tolerable upper intake level from all sources. That number is a safety boundary, not a universal daily target. Total intake, health status, medication, sun exposure, diet, and laboratory results all matter.[1]
Our honest read: this is a clear one-capsule formula for adults who intentionally want a higher-dose D3 routine with K2, vitamin C, and calcium. It does not guarantee stronger bones, prevent illness, or replace individualized clinical guidance.
Read the Four Numbers Correctly
NutrientRole in the formulaAmount per capsule
Vitamin D3Supports calcium absorption and normal bone, muscle, and immune function.4,000 IU / 100 mcg.
Vitamin K2MK-7 form of vitamin K, a nutrient used by bone- and clotting-related proteins.100 mcg.
Vitamin CAn antioxidant nutrient with roles in collagen synthesis and immune function.80 mg.
CalciumA structural mineral; this serving supplies part, not all, of the Daily Value.120 mg.
Why 4,000 IU needs a second look
The vitamin D amount equals the adult upper intake level. Review other vitamin D products and fortified foods so the same nutrient is not unintentionally stacked.[1]
What this page does not promise
It does not promise a fracture, deficiency, or infection outcome, or make vitamin K safe with warfarin. Those questions require individual context.[1][2]
Bone + muscle support, made simple.

Vitamin D
NIH explains vitamin D’s established roles, intake recommendations, adult upper limit, deficiency context, and medication considerations.
It is a once-daily formula for bone, muscle, and immune support, built with vitamin D3, vitamin K2 as MK-7, vitamin C, and calcium.[1][2][3][4]
How much vitamin D3 is in one capsule?
One capsule provides 4,000 IU, equal to 100 mcg, vitamin D3. That amount equals the NIH adult tolerable upper intake level from all sources, so review your total intake.[1]
What form of vitamin K is used?
The Supplement Facts panel lists 100 mcg vitamin K2 as menaquinone-7, commonly shortened to MK-7.
How much calcium does it provide?
One capsule provides 120 mg calcium as calcium citrate, equal to 9% of the U.S. Daily Value. It is not a complete day’s calcium intake.
How should I take it?
The current label says adults take 1 capsule daily with food and water.
Can I take it with warfarin?
Do not make a vitamin K change without speaking with the clinician who manages warfarin or another anticoagulant. NIH advises keeping vitamin K intake consistent because the interaction can be serious.[2]
Does 4,000 IU mean everyone should take that much?
No. An upper intake level is not a daily goal. Vitamin D needs vary, and testing or healthcare guidance may be appropriate before sustained use of a high-dose routine.[1]
Where is this product made?
The finished label states: European pharmacist-formulated, sourced globally, and made in Hungary.

What to Look for in a Certificate
A useful report should help you match the document to your bottle and see what was tested. FDA quality guidance centers on identity, purity, strength, composition, and limits on contaminants. Read the FDA quality guidance ↗
01
Lot or batch
The report identifier should match the lot or batch printed on your bottle.
02
Product identity
Look for the named product or material and the test or examination method used.
03
Strength and composition
When potency is tested, compare the actual result with the specification or labeled amount.
04
Purity and safety
Look for contaminant or microbial limits, actual results, and a clear pass or specification.
Lot-specific documents matter
Vitamin D3 + K2 documentation
No current finished-product, lot-specific certificate was found in the public product record. Match any future report to the product name and the lot or batch printed on your bottle.
Certificates are lot-specific. A report for one lot does not automatically describe a later production run, and a certificate evaluates product specifications - not clinical effectiveness.
How to Use Vitamin D3 + K2
Start with the product label, then compare it with public guidance. Label directions, nutrient targets, and research doses answer different questions.
What the label says1 capsule daily with food
The current label says adults take 1 capsule daily with food and water.
Per capsule: 4,000 IU (100 mcg) vitamin D3, 100 mcg vitamin K2 as MK-7, 80 mg vitamin C, and 120 mg calcium
What public guidance says4,000 IU is the adult upper limit
NIH lists 4,000 IU (100 mcg) per day as the tolerable upper intake level for adults from all sources. An upper limit is a safety boundary, not a target that everyone needs.
The labeled serving itself reaches the adult vitamin D upper limit. Count vitamin D from this product, other supplements, and fortified foods together, and use clinician-directed testing when appropriate.
A simple label-led routine
1
Take one capsule
Use the complete label serving once daily.
2
Take it with food and water
That direction comes from the current product label.
3
Review the rest of your routine
Avoid unintentionally stacking additional vitamin D or vitamin K products.
Use the label as the default
Use the label as the ceiling unless a healthcare professional gives you a different plan. More is not automatically better, and vitamin D needs vary with diet, sun exposure, age, health status, and laboratory results.
Check before use
This serving is high in vitamin D and includes vitamin K, so medication and total daily intake matter.
Ask a healthcare professional before use if you take warfarin or another anticoagulant; vitamin K intake should be kept consistent.
Ask before use if you have kidney disease, hypercalcemia, hyperparathyroidism, sarcoidosis, or another condition affecting calcium or vitamin D metabolism.
Ask before use if you are pregnant, nursing, take medication, or already use another vitamin D, vitamin K, or calcium supplement.
The facility also processes fish, crustacean shellfish, peanuts, and tree nuts.
Stop use if you experience an adverse reaction, and keep out of reach of children.
