NOW Foods Vitamina K-2, 100 Cápsulas

What is Vitamin K2?

Vitamin K2, also known as menaquinone, is a form of vitamin K naturally found in fermented foods and animal products. Unlike vitamin K1 (phylloquinone), K2 has higher bioavailability and remains in the body longer, making it especially valuable for supporting key physiological processes. This NOW Foods supplement combines 100 mcg of menaquinone per capsule with 300 mg of alfalfa powder, a plant-based source that complements its nutritional profile.

Benefits Supported by the EFSA

The European Food Safety Authority (EFSA) has approved two health claims for vitamin K: "contributes to normal blood clotting" and "contributes to the maintenance of normal bones." These claims are based on solid scientific evidence and are applicable to vitamin K2. By including this supplement in your daily routine, you naturally support these fundamental processes.

The K2 form (menaquinone-4 and menaquinone-7) is the most active in the body and has been linked to better calcium utilization, helping to direct it to the bones and teeth, where it is needed, and preventing its accumulation in soft tissues.

How to Take Vitamin K2?

The recommended dose for adults is one (1) capsule daily, preferably with a meal containing some fat to optimize absorption, as vitamin K is fat-soluble. Each NOW Foods capsule provides 100 mcg of vitamin K2 and 300 mg of alfalfa. Do not exceed the recommended daily dose.

For better assimilation, it can be combined with vitamin D3 and calcium, although it is always advisable to consult a healthcare professional before starting any supplementation.

Possible Side Effects and Contraindications

Vitamin K2 is generally well tolerated at recommended doses. However, people taking anticoagulant medications (such as warfarin or acenocoumarol) should consult their doctor before taking vitamin K supplements, as it can interfere with their effect. Also, if you are pregnant, breastfeeding, or have any medical condition, consult a specialist.

This product should not be used as a substitute for a balanced diet. Keep out of reach of children.

Frequently Asked Questions

What is the difference between vitamin K1 and K2?

Vitamin K1 (phylloquinone) is mainly found in leafy green vegetables and is essential for blood clotting. Vitamin K2 (menaquinone) is found in fermented and animal-derived foods and is considered more effective for bone and cardiovascular health due to its longer half-life and tissue distribution capacity.

Can I take vitamin K2 with other supplements?

Yes, it is common to combine vitamin K2 with vitamin D3 and calcium to support bone health. However, it is always advisable to consult a healthcare professional to adjust dosages and avoid possible interactions.

What does it mean that vitamin K2 is the "most biologically active form"?

Menaquinone (K2) has a longer side chain than phylloquinone (K1), allowing it to remain in the bloodstream longer and be more efficiently absorbed by tissues. This makes it especially useful for processes such as calcium fixation in bones.
