Solgar Vitamin K2 (MK-7) 100 mcg - 50 Vegetable Capsules, Pack of 4

What is vitamin K2 and why is it important?

Discover Solgar Naturally Sourced — Vitamin K2, also known as menaquinone, is a fat-soluble vitamin essential for the body. Unlike vitamin K1 (found in green leafy vegetables), K2 is not easily found in the diet and is produced in small amounts by the intestinal microbiota. Its most active and bioavailable form is menaquinone-7 (MK-7), which is naturally extracted from natto, a traditional Japanese food made from fermented soybeans. Vitamin K2 plays a key role in bone and cardiovascular health, as it activates proteins that help fix calcium in the bones and prevent its accumulation in the arteries.

This 4-bottle pack of Solgar Naturally Sourced Vitamin K2 provides 100 mcg of MK-7 per vegetable capsule, with a total of 200 capsules (50 per bottle). It is a convenient and economical way to ensure an adequate intake of this important vitamin.

Health benefits of vitamin K2

The European Food Safety Authority (EFSA) has approved several health claims for vitamin K. These include:

• Bone maintenance: Vitamin K contributes to the maintenance of bones under normal conditions. This is because it activates osteocalcin, a protein that binds calcium to the bone matrix, promoting bone density and strength.
• Blood clotting: Vitamin K contributes to normal blood clotting. It is necessary for the synthesis of clotting factors in the liver.

In addition, vitamin K2 (especially MK-7) has been associated with cardiovascular health, although EFSA has not approved a specific claim for this. Evidence suggests that it activates MGP (Matrix Gla Protein), which inhibits arterial calcification, helping to maintain the flexibility of blood vessels. These benefits make vitamin K2 a fundamental nutrient for people concerned about their bone and heart health.

How much vitamin K2 to take per day? Recommended dose

Adequate vitamin K intake varies by age and sex. In adults, EFSA recommends a daily intake of 70-75 mcg for men and 60-65 mcg for women. However, these amounts mainly refer to vitamin K1. For K2, there is no specific official recommendation, but many experts suggest doses between 45 and 100 mcg per day of MK-7 to maintain optimal health.

Each capsule of Solgar Vitamin K2 provides 100 mcg of MK-7, which easily covers daily needs. It is recommended to take one capsule a day with a meal containing some fat to improve absorption, as it is fat-soluble. It is important not to exceed the recommended daily dose and to consult a healthcare professional before starting any supplementation, especially if taking anticoagulants.

Differences 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 (a few hours), so it requires multiple doses per day to maintain stable levels. In contrast, MK-7 remains active in the blood for more than 24 hours, allowing for a single daily dose and greater consistency in its effects.

MK-7 is naturally obtained from natto, while MK-4 is usually synthetic. In addition, MK-7 has shown greater bioavailability and efficacy in clinical studies to activate vitamin K-dependent proteins. For this reason, Solgar has chosen the naturally sourced MK-7 form, guaranteeing maximum quality and effectiveness.
