About Ostrovit – 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 D as cholecalciferol — the same form the body produces through sunlight exposure — alongside 100 µg of vitamin K as menaquinone-7 (MK-7), a highly bioavailable form of vitamin K2 derived from Bacillus subtilis natto.
Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, the maintenance of normal blood calcium levels, the maintenance of normal bones, the maintenance of normal muscle function, the maintenance of normal teeth, the maintenance of the normal function of the immune system, and the normal function of the immune system in children. Vitamin K contributes to normal blood clotting and the maintenance of normal bones.
Formulated in a compact tablet format, Ostrovit Vitamin D3 4000 + K2 provides a straightforward, no-fuss way to support your daily intake of these two important nutrients. The pack contains 100 tablets, representing a 100-day supply at the recommended serving of one tablet per day.
