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 normal absorption and utilisation of calcium and phosphorus, the maintenance of normal bones, normal muscle function, 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.
