D3 + K2
Vitamin K, complementary role
Vitamin K contributes to normal blood clotting and the maintenance of normal bones.
Designed for routine use
One capsule provides 20 µg vitamin D3 and 90 µg vitamin K2 (MK-7), with the dose shown plainly rather than buried inside a blend.

03 / Transparency
Why this
formula.
What we can explain now — and what will only be claimed once a real production batch can prove it.
Ingredients
One capsule provides 20 µg (800 IU) vitamin D3 and 90 µg vitamin K2 as MK-7. The amounts are stated individually rather than hidden in a blend.
Forms
Vitamin D3 is cholecalciferol. MK-7 is a menaquinone form of vitamin K2 used in supplements; available human data indicate it is absorbed and has a longer half-life than vitamin K1, but we do not present that as proof of superior health outcomes.
Dose
20 µg vitamin D is 400% of the EU NRV and one-fifth of EFSA's adult vitamin D UL of 100 µg/day. 90 µg vitamin K is 120% of the EU NRV; EFSA has not established a vitamin K UL.
Evidence
Authorised EU claims include vitamin D's contribution to normal calcium/phosphorus absorption, normal bones, muscle and immune function; vitamin K contributes to normal blood clotting and maintenance of normal bones.
Manufacturing
Facility, country of manufacture and verified quality certifications will be published after the commercial manufacturing agreement is finalised. We will not display certifications we cannot document.
Testing & COA
No commercial batch exists yet, so there is no batch COA to publish. After production, the batch page is intended to show the lot number, test panel, laboratory, test date and report where available.
Pre-production
Batch verification
No lab report is displayed until a commercial batch exists and has actually been tested. Future batch records are intended to identify the lot, testing scope, laboratory and report date.
04 / FAQ
Questions,
answered.
Short answers based on authorised EU claims, safety guidance and human research — without turning uncertainty into marketing.
Why combine D3 and K2?
They are combined for a simple daily routine. Each nutrient has its own established physiological roles; we do not claim that they must be taken together for either one to work.
Why 20 µg / 800 IU of vitamin D3?
20 µg equals 800 IU. It is below EFSA's adult tolerable upper intake level of 100 µg/day and provides a clearly stated daily amount.
Why MK-7?
MK-7 is one of the better-studied vitamin K2 forms used in supplements. It is well absorbed and has a longer circulating half-life than vitamin K1 in human data, but evidence does not justify claiming universal superiority for every outcome.
Can I take this with warfarin or similar anticoagulants?
Vitamin K can seriously interact with vitamin-K-antagonist anticoagulants such as warfarin. If you use one, discuss vitamin K supplements with your clinician or pharmacist before use.
Is more vitamin D always better?
No. Vitamin D has a tolerable upper intake level. More than needed is not automatically more beneficial, and excessive long-term intake can be harmful.
05 / How to use
Make it
automatic.
Take
Take 1 capsule daily.
Pair
Take with a meal; fat-soluble vitamins are commonly taken with food.
Medication check
Vitamin K can interact with vitamin-K-antagonist anticoagulants. Ask your clinician or pharmacist before use if you take these medicines.
Food supplement. Do not exceed the recommended daily intake. Food supplements should not replace a varied, balanced diet and healthy lifestyle. Keep out of reach of young children. Vitamin K can interact with vitamin-K-antagonist anticoagulants.
