About the formula

100 µg D3. 70 µg K2 as MK-7. In olive oil.

Vitamin D and vitamin K work on the same pathway: vitamin D contributes to the normal absorption and utilisation of calcium, and vitamin K contributes to the maintenance of normal bones. Welleo delivers 100 µg (4,000 IU) of vitamin D3 and 70 µg of vitamin K2 as MK-7, pre-dissolved in olive oil.

That is 2,000% of the NRV for vitamin D — the EFSA tolerable upper intake level for adults is 100 µg a day from all sources combined. Do not take it alongside another vitamin D supplement, and read the warnings below before you start.

Questions before you start

Why must Vitamin D3 always be paired with Vitamin K2?

They act on the same pathway. Vitamin D contributes to the normal absorption and utilisation of calcium, and vitamin K contributes to the maintenance of normal bones. Those are the two claims EU law authorises for these nutrients, and they are the reason the two are formulated together here: 100 µg of D3 with 70 µg of K2 as MK-7.

What does the MK-7 designation mean for Vitamin K2?

Menaquinone-7 (MK-7) is an advanced, long-acting form of Vitamin K2. Unlike standard Vitamin K1 which leaves your system within hours, MK-7 remains active in your bloodstream for over 48 hours. This extended timeline ensures a steady, constant supply to your bones and blood vessel walls.

Are there any safety limits or contraindications?

Yes. More information means smarter decisions. Because Vitamin K2 naturally participates in your body’s coagulation systems, individuals taking prescription anticoagulant medications (like Warfarin or Sintrom) must not consume this supplement without strict medical clearance. Do not exceed the recommended daily dose. This product provides 100 µg of vitamin D a day, which is the tolerable upper intake level for adults from all sources combined. Do not take it alongside another vitamin D supplement without medical advice.
