Frequently Asked Questions

How much does each capsule contain?

Each capsule provides 125 µg (5000 IU) of vitamin D3 (2500% NRV), 2100 µg of vitamin K — 1000 µg of K1, 1000 µg of K2 MK-4 and 100 µg of K2 MK-7 — (2800% NRV) and 1000 µg of iodine (667% NRV).

The amounts of vitamin D (125 µg) and iodine (1000 µg) are above the tolerable upper intake levels set by EFSA for adults (100 µg and 600 µg per day, respectively). It is therefore recommended to use this product only under medical supervision and not to combine it with other sources of vitamin D or iodine.

Not without medical advice. Vitamin K may interfere with anticoagulants such as warfarin, and high-dose iodine is not recommended for people with thyroid conditions or taking thyroid medication.

Vitamin D contributes to the maintenance of normal bones and teeth and to the normal function of the immune system; vitamin K contributes to normal blood clotting and to the maintenance of normal bones; iodine contributes to the normal production of thyroid hormones and to normal energy-yielding metabolism.
