OstroVit Vitamin K2 200 Natto MK-7 90 Tablets is a high-strength vitamin K supplement for adults, providing 200 µg of vitamin K2 in the menaquinone-7 (MK-7) form per daily tablet.
The vitamin K2 is derived from Bacillus subtilis natto, associated with the traditional Japanese fermented soy food natto. MK-7 is one of the naturally occurring forms of vitamin K2 and is widely used in dedicated vitamin K supplements.
Each tablet provides 200 µg of vitamin K2 – 267% of the Nutrient Reference Value (NRV).
Vitamin K contributes to the maintenance of normal bones and to normal blood clotting, making this a focused option for adults who want to supplement vitamin K separately rather than relying solely on a general multivitamin.
The straightforward once-daily tablet format makes supplementation easy to incorporate into an existing vitamin and mineral routine.
With 90 tablets per container and 1 tablet per daily serving, each pack provides a convenient 90-day supply.
