Doctor's Best Vitamin K2 MK7 with MenaQ7 - 45 mcg, 180 Vegan Capsules

What is Vitamin K2 and why is it important?

Discover Doctor'S Best Natural — Vitamin K2, also known as menaquinone, is a fat-soluble vitamin essential for the body. Unlike vitamin K1, which is mainly found in leafy green vegetables, K2 is obtained from fermented and animal sources. This vitamin plays a crucial role in activating proteins that regulate calcium distribution in the body, promoting its deposition in bones and teeth, while helping to prevent its accumulation in soft tissues such as arteries.

The MK-7 form (menaquinone-7) is especially valued for its long half-life in the body, allowing for sustained action with a single daily dose. The product we present uses MenaQ7®, a high-quality vitamin K2 obtained from fermented chickpeas, guaranteeing a vegan and non-GMO source.

Health Benefits of Vitamin K2

Vitamin K2 contributes to the maintenance of normal bones and normal blood clotting, according to the European Food Safety Authority (EFSA). These benefits are supported by decades of scientific research. By activating osteocalcin, a protein that fixes calcium in the bone matrix, K2 helps maintain bone mineral density, especially in life stages where bone loss is more pronounced, such as menopause or aging.

Furthermore, vitamin K2 contributes to the normal functioning of the cardiovascular system by activating MGP (Matrix Gla Protein), which inhibits calcification of the arteries. This makes it an important ally for heart and blood vessel health. It is worth noting that, for optimal health, vitamin K2 is often recommended to be combined with vitamin D and calcium, as they act synergistically.

How much Vitamin K2 do you need? Recommended dosage

The recommended daily dose of vitamin K2 can vary depending on age, health status, and diet. For adults, the adequate intake of vitamin K (summing K1 and K2) is around 70-90 mcg per day. However, many experts suggest a specific K2 intake of at least 45 mcg for bone and cardiovascular benefits.

Differences between MK-4 and MK-7

There are two main forms of vitamin K2: MK-4 (menaquinone-4) and MK-7 (menaquinone-7). MK-4 is found in small amounts in animal foods such as liver and egg yolk, but it has a short half-life in the body, of just a few hours. In contrast, MK-7, present in fermented foods like natto, remains active in the blood for more than 24 hours, allowing for more efficient and stable dosing.

In addition, MK-7 is more completely absorbed and has greater bioavailability than MK-4, which means that a smaller dose is needed to achieve the same effects. For these reasons, MK-7 is the preferred form in high-quality vitamin K2 supplements, such as the one we offer here.

How to choose the best Vitamin K2 supplement

When selecting a vitamin K2 supplement, it is important to consider several factors: the form (MK-7 is preferable), the source (vegan or not), purity, and certifications. This product uses MenaQ7®, a patented brand of vitamin K2 MK-7 derived from fermented chickpeas, which guarantees its vegan origin and high bioavailability.

In addition, it is non-GMO, gluten-free, soy-free, and suitable for vegans. Doctor's Best is a brand with over 35 years of experience in the supplement industry, committed to research and quality control. Each batch undergoes rigorous testing to ensure its purity and potency.

Possible side effects and contraindications

Vitamin K2 is generally considered safe at recommended doses. However, in people taking anticoagulants (vitamin K antagonists such as warfarin), vitamin K consumption can interfere with medication and should be supervised by a healthcare professional. It is not recommended to exceed the indicated daily dose.
