Carlson Vitamin K2 MK-4 (Menatetrenone) - 60 Capsules

What is vitamin K2 and why is it important?

Vitamin K2, also known as menaquinone, is a form of vitamin K that plays a crucial role in bone and cardiovascular health. Unlike vitamin K1 (phylloquinone), which is found mainly in green leafy vegetables and is essential for blood clotting, vitamin K2 is more bioavailable and remains in the body longer. The MK-4 form (menatetrenone) is one of the most studied variants and is found in animal-derived foods such as liver and dairy products. However, many people do not get enough vitamin K2 through their diet, so a quality supplement can be a convenient option.

Health benefits of vitamin K2

Vitamin K2 contributes to essential functions supported by the European Food Safety Authority (EFSA):

• Normal blood clotting: Vitamin K activates proteins necessary for clotting, helping to maintain healthy circulation.
• Maintenance of bones under normal conditions: It activates osteocalcin, a protein that fixes calcium in the bone matrix, contributing to bone density and strength.
• Cardiovascular function: By activating matrix Gla protein (MGP), vitamin K2 helps prevent arterial calcification, supporting heart and blood vessel health.

In addition, vitamin K2 promotes the proper transport of calcium to bones and teeth, preventing its accumulation in soft tissues.

How much vitamin K2 do you need? Recommended dosage

Each Carlson Vitamin K2 MK-4 capsule provides 5 mg (5000 mcg) of menatetrenone, a significant dose that can help meet daily vitamin K2 needs. The recommended dosage is one capsule daily, preferably with a fat-containing meal to improve absorption. Consult a healthcare professional to adjust the dose according to your individual needs, especially if you are taking anticoagulant medication.

Differences between vitamin K1 and K2

Vitamin K1 (phylloquinone) is found in green leafy vegetables and is primarily used by the liver to activate clotting factors. Vitamin K2 (menaquinone), on the other hand, is distributed to peripheral tissues such as bones and arteries, where it activates key proteins for bone and cardiovascular health. The MK-4 form is the most active and fast-acting, while the MK-7 and MK-9 forms have a longer half-life. The Carlson supplement contains MK-4, ideal for those seeking a direct and effective supply.

How to choose the best vitamin K2 supplement

When selecting a vitamin K2 supplement, consider the following aspects:

• Form of vitamin K2: MK-4 (menatetrenone) is the most studied and bioavailable form. Carlson uses high purity MK-4.

Possible side effects and contraindications

Vitamin K2 is generally safe at recommended doses. However, people taking anticoagulants such as warfarin should consult their doctor before taking vitamin K supplements, as they may interfere with the medication. No significant adverse effects have been reported with doses of up to 5 mg per day. This product is a food supplement and should not be used as a substitute for a balanced and varied diet.
