Vitamin K2 (Menaquinone-7) 100 mcg, 50 Vegetarian Capsules - BlueBonnet

What is Vitamin K2?

Vitamin K2, also known as menaquinone, is a fat-soluble form of vitamin K essential for the body. There are several types of menaquinones, with menaquinone-7 (MK-7) being the most studied for its excellent bioavailability and prolonged half-life. This BlueBonnet supplement provides 100 mcg of MK-7 per capsule, obtained from natto extract (soy fermented by Bacillus subtilis). It is a high-quality option for those who wish to supplement their vitamin K2 intake naturally and effectively.

Vitamin K2 plays key roles in the body, especially in calcium regulation. While vitamin K1 (phylloquinone) is found mainly in green leafy vegetables and participates in clotting, K2 acts at bone and cardiovascular levels. This difference makes MK-7 supplementation particularly relevant for adults seeking to maintain their long-term health.

Benefits of Vitamin K2 for Bone and Cardiovascular Health

According to health claims authorized by the EFSA (European Food Safety Authority), vitamin K contributes to the maintenance of normal bones and to normal blood clotting. MK-7 activates vitamin K-dependent proteins, such as osteocalcin, which binds calcium to the bone matrix, and matrix Gla protein (MGP), which inhibits arterial calcification.

An adequate intake of vitamin K2 is, therefore, important for bone mineral density and vascular flexibility. Numerous observational studies associate high MK-7 intake with a lower risk of fractures and better cardiovascular health. However, it is important to remember that food supplements should not replace a balanced diet or a healthy lifestyle. Consult your doctor before starting any supplementation, especially if you are taking anticoagulants.

Key Ingredients: High-Quality Menaquinone-7

Each vegetable capsule contains 100 mcg of menaquinone-7 (MK-7) from natto extract. Natto is a traditional Japanese food rich in vitamin K2, obtained by fermenting soybeans with the bacterium Bacillus subtilis. This process naturally produces the active and stable form of MK-7.

Additional ingredients are minimal: vegetable cellulose capsule and vegetable magnesium stearate as a lubricant. It is non-GMO, vegan, certified kosher, and free of gluten, soy, dairy, egg, fish, shellfish, tree nuts, peanuts, wheat, and sesame. It also contains no added sugars or sodium. This makes it a product suitable for people with multiple food sensitivities.

BlueBonnet is committed to offering pure, high-quality supplements, manufactured according to good manufacturing practices. Each batch undergoes identity, purity, and potency testing to ensure product consistency.

How to choose a good vitamin K2 supplement?

When selecting a vitamin K2 supplement, it is advisable to consider several aspects. The MK-7 form is preferable to MK-4 due to its higher bioavailability and longer duration of action. The dosage of 100 mcg per day is the most common in studies and is considered sufficient to cover additional needs. It is also important that the product is free of unnecessary allergens and additives, and that it has certifications such as vegan or kosher if they align with your values.

Dosage and Recommendations for Use

It is recommended to take one (1) vegetable capsule daily, preferably with a meal containing some fat to optimize absorption, as vitamin K is fat-soluble. Do not exceed the recommended daily dose. Keep the container closed, in a cool, dry place, out of reach of children.

Food supplements should not be used as a substitute for a balanced and varied diet or a healthy lifestyle. If you are pregnant, breastfeeding, or under medical treatment (especially with anticoagulants), consult a healthcare professional before taking this product.
