NOW Foods Vitamin K-2 MK-7 100 mcg, 60 Cápsulas Veganas

What is Vitamin K2 MK-7?

Vitamin K2, also known as menaquinone, is a fat-soluble form of vitamin K essential for various bodily processes. Specifically, the MK-7 variant (menaquinone-7) stands out for its higher bioavailability and prolonged half-life compared to other forms of vitamin K. This NOW Foods supplement provides 100 mcg of vitamin K2 in its MK-7 form, sourced from non-GMO soy fermentation, presented in convenient vegan capsules.

Vitamin K2 is naturally found in fermented foods such as natto, but its presence in the Western diet is often limited. Therefore, a quality supplement like this helps to meet daily needs without relying exclusively on diet.

Benefits endorsed by the EFSA

According to the European Food Safety Authority (EFSA), vitamin K contributes to normal blood coagulation and the maintenance of normal bones. These claims are supported by scientific evidence and are applicable to vitamin K2, as it is part of the vitamin K family.

Vitamin K2 activates vitamin K-dependent proteins, such as osteocalcin (involved in bone mineralization) and matrix Gla protein (which helps maintain arterial flexibility). By taking MK-7 regularly, the binding of calcium to bones is promoted, and its deposition in blood vessels is prevented, thus contributing to comprehensive bone and cardiovascular health.

How to take vitamin K2 correctly?

The recommended dose by NOW Foods is one capsule daily, preferably with a meal containing fats to optimize its absorption, as vitamin K is fat-soluble. Each vegan capsule provides 100 mcg of MK-7, an adequate amount for adults wishing to supplement their daily intake.

It is important not to exceed the recommended dose and to keep the product in a cool, dry place, out of reach of children. If you are taking anticoagulants (such as warfarin or acenocoumarol), it is essential to consult your doctor before taking any vitamin K supplement, as it may interfere with the medication.

Possible side effects and contraindications

Vitamin K2 is generally well tolerated at recommended doses. However, in individuals with individual sensitivity, mild digestive discomfort may occur. The main contraindications are for those taking oral anticoagulants, as vitamin K can reduce their effectiveness. Likewise, pregnant or breastfeeding women should consult a healthcare professional before using this supplement.

This product should not be used as a substitute for a balanced diet. Do not exceed the recommended dose. Keep out of reach of children.

Frequently asked questions

What is the difference between vitamin K1 and K2?

Vitamin K1 (phylloquinone) is found mainly in green leafy vegetables and is essential for blood coagulation. Vitamin K2 (menaquinone), on the other hand, is produced by bacterial fermentation and plays a more prominent role in bone and cardiovascular health, thanks to its longer half-life and ability to activate specific proteins.

Why choose the MK-7 form?

MK-7 is the vitamin K2 variant with the longest half-life (up to 72 hours), which allows stable blood levels to be maintained with a single daily dose. In addition, it is efficiently absorbed and distributed throughout the body, maximizing its benefits.

Can I take this supplement with vitamin D3 and calcium?

Yes, in fact it is a frequent combination, since vitamin D3 promotes calcium absorption and vitamin K2 helps direct it to the bones. However, it is always advisable to consult a professional to adjust doses according to individual needs.
