OSTROVIT Vitamin D3 4000 + K2 (110 tabs)

OstroVit Vitamin D3 4000 + K2 combines two essential fat-soluble vitamins in a convenient once-daily tablet. Each tablet delivers 4000 IU (100 µg) of vitamin D3 as cholecalciferol alongside 100 µg of vitamin K2 in the highly bioavailable menaquinone-7 (MK-7) form, sourced from Bacillus subtilis natto. Together, these two vitamins work in tandem to support several important physiological functions.

Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, the maintenance of normal blood calcium levels, normal bones, normal muscle function, normal teeth, and the normal function of the immune system. Vitamin K contributes to normal blood clotting and the maintenance of normal bones. With 110 tablets per pack, this product offers a long-lasting supply suitable for consistent, daily supplementation.

This formula is particularly suited to adults — including those over 75 years of age — who wish to maintain adequate vitamin D and K2 levels, especially during periods of reduced sunlight exposure. As with any high-dose vitamin D supplement, a 25-(OH)D blood test and consultation with a healthcare professional prior to use are strongly advised.
