About Ostrovit – Vitamin D3 4000 + K2 (110 tabs)

OSTROVIT Vitamin D3 4000 + K2 combines two essential fat-soluble vitamins in a single convenient tablet. Each serving delivers 4000 IU (100 µg) of Vitamin D3 as cholecalciferol — the same form naturally produced by the skin upon sun exposure — alongside 100 µg of Vitamin K2 in its highly bioavailable MK-7 form, derived from Bacillus subtilis natto.

Vitamin D contributes to the normal function of the immune system, the maintenance of normal bones and teeth, normal muscle function, and the normal absorption and utilisation of calcium and phosphorus. Vitamin K contributes to normal blood clotting and the maintenance of normal bones.

Formulated for adults, and specifically noted as suitable for persons over 75 years of age, this product offers a straightforward daily tablet to help support adequate intake of both nutrients. With 110 tablets per pack, each purchase provides a generous 110-day supply.
