Jarrow Formulas MK-7 90 mcg – Vitamina K2 (Menaquinona-7) – 120 Softgels

What is vitamin K2 MK-7?

Vitamin K2, also known as menaquinone, is a form of vitamin K essential for the health of the body. There are several types of menaquinones, with MK-7 being one of the most studied due to its bioavailability and prolonged activity. Jarrow Formulas MK-7 offers 90 mcg of this vitamin in each softgel, presented in its bioactive form for optimal utilization by the body.

This supplement is designed for individuals who wish to support bone and cardiovascular health, as well as normal blood coagulation. Vitamin K2 MK-7 is obtained through the fermentation of soy (natto) and is recognized for its ability to remain active in the body for longer than other forms of vitamin K.

Benefits of vitamin K2 for health

Vitamin K contributes to the maintenance of normal bones and normal blood coagulation, according to the European Food Safety Authority (EFSA). These benefits are supported by science and make vitamin K2 a key nutrient for overall health.

In addition, vitamin K2 plays an important role in regulating calcium in the body, helping to direct calcium to the bones and teeth, where it is needed, and preventing its accumulation in the arteries. Although there is no approved health claim for cardiovascular health, research suggests that adequate vitamin K2 intake may contribute to maintaining arterial flexibility.

MK-7, in particular, is the most active and long-lasting form, allowing for effective supplementation with a single daily dose.

How much vitamin K2 to take per day?

The recommended dose of Jarrow Formulas MK-7 is one softgel per day, which provides 90 mcg of vitamin K2 (menaquinone-7). This amount is suitable for most adults and has been established as an effective dose to maintain optimal vitamin K levels in the body.

It is important to follow the manufacturer's instructions and not exceed the recommended dose without consulting a healthcare professional. Vitamin K2 is fat-soluble, so it is best absorbed when taken with foods containing healthy fats.

Difference between MK-4 and MK-7

There are two main forms of vitamin K2: menaquinone-4 (MK-4) and menaquinone-7 (MK-7). MK-4 has a short half-life in the body and is found in small amounts in animal products such as liver and egg yolk. On the other hand, MK-7 has a longer half-life and is mainly obtained from natto (fermented soy).

MK-7 is considered more effective at maintaining stable vitamin K levels in the blood throughout the day, making it the preferred option for supplementation. Jarrow Formulas uses the MK-7 form for its superior bioavailability and prolonged activity.
