Vitamin D3 4000 + K2 – 100 tablets

Ostrovit Vitamin D3 4000 + K2 combines two essential fat-soluble vitamins in a single convenient tablet. Each daily serving delivers 100 µg (4000 IU) of Vitamin D3 as cholecalciferol alongside 100 µg of Vitamin K2 as high-bioavailability menaquinone-7 (MK-7), sourced from Bacillus subtilis natto . This pairing is designed to support everyday wellbeing through two well-established nutritional roles in one easy-to-take format.

Vitamin D contributes to the normal function of the immune system, the maintenance of normal bones, 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 vitamins offer complementary support for bone health and broader physiological function.

Formulated for adults — including those over 75 years of age — Ostrovit Vitamin D3 4000 + K2 provides a straightforward, high-potency option for those looking to maintain adequate intake of both vitamins, particularly during periods of limited sun exposure or increased nutritional need. One pack contains 100 tablets, representing a full 100-day supply at the recommended daily serving.
