About Ostrovit – Vitamin D3 + K2

Ostrovit Vitamin D3 + K2 combines two essential fat-soluble vitamins in a single convenient tablet. Each serving delivers 2000 IU (50 µg) of Vitamin D3 as cholecalciferol — the same form naturally produced by the body in response to sunlight — 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. Together, these two vitamins are widely recognised as complementary nutrients that support skeletal and cardiovascular health.

Formulated for adults, this 90-tablet pack provides a three-month supply at the recommended daily dose of one tablet. The clean, concise ingredient list and compact tablet format make it a straightforward addition to any daily supplement routine.
