Carlson - Vitamin K2 MK-4 (Menatetrenone), 5 mg, 180 Capsules

What is Vitamin K2 and why is it important?

Vitamin K2, also known as menaquinone, plays a fundamental role in bone and cardiovascular health. Unlike vitamin K1, which is found in green vegetables, K2 is more bioavailable and active in the body. The MK-4 form (menatetrenone) is one of the most studied variants, with a rapid and effective action. This Carlson supplement provides 5 mg of vitamin K2 MK-4 per capsule, in an easy-to-swallow and soy-free presentation.

Benefits of Vitamin K2 for health

According to the European Food Safety Authority (EFSA), vitamin K contributes to the maintenance of normal bones and normal blood coagulation. Vitamin K2 activates proteins such as osteocalcin, which helps fix calcium in the bones, and MGP (matrix Gla protein), which prevents calcification of blood vessels. In this way, it contributes to bone and cardiovascular health.

How much Vitamin K2 do you need? Recommended dosage

Each Carlson capsule provides 5 mg (5000 µg) of vitamin K2 MK-4. This dose is suitable for adults seeking additional bone support. The adequate intake of vitamin K for adults established by the EFSA is 70 µg per day, but higher doses may be beneficial under professional supervision. Consult your doctor to determine the appropriate dose for you.

Differences between MK-4 and MK-7

There are two main forms of vitamin K2: MK-4 and MK-7. MK-4 is of synthetic origin but identical to that produced by the body, with a short half-life and rapid action. MK-7 is found in fermented foods such as natto and has a longer half-life. Both contribute to bone health, but MK-4 is often preferred for high-dose formulations due to its rapid onset of action.

How to choose the best Vitamin K2 supplement

When selecting a vitamin K2 supplement, it is important to consider purity, absence of allergens, and manufacturer quality. Carlson is a renowned brand that tests its products in FDA-registered laboratories to ensure potency and quality. This supplement is soy-free, easy to swallow, and contains no unnecessary additives.

Is it safe to take Vitamin K2? Possible side effects

Vitamin K2 is generally safe at recommended doses. No significant adverse effects have been reported with doses up to 45 mg per day. However, people taking anticoagulants such as warfarin should consult their doctor before taking vitamin K supplements, as it may interfere with medication. This product is a food supplement and should not be used as a substitute for a balanced diet.
