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 synthesised by the body — alongside 100 µg of Vitamin K2 as the highly bioavailable MK-7 form, derived from Bacillus subtilis natto. Together in one daily tablet, these nutrients support multiple aspects of everyday wellbeing.
Vitamin D contributes to the normal function of the immune system, the maintenance of normal bones and teeth, normal muscle function, and normal absorption and utilisation of calcium and phosphorus. Vitamin K contributes to normal blood clotting and to the maintenance of normal bones. This combination makes Ostrovit Vitamin D3 + K2 a practical choice for adults looking to support both skeletal health and immune function year-round.
Formulated with a clean, minimal ingredient list and produced in tablet form for easy, precise daily dosing, each pack of 90 tablets provides a full 90-day supply at the recommended serving of one tablet per day.
