Healthy Origins Vitamina K2 100 mcg (MK-7) - 60 Cápsulas Vegetales

What is vitamin K2 and why is it important?

Vitamin K2, also known as menaquinone, is a fat-soluble form of vitamin K that plays a crucial role in calcium metabolism. Unlike vitamin K1, which is found in leafy green vegetables, K2 is primarily obtained from fermented foods and bacterial conversion in the gut. The human body uses it to activate proteins that regulate blood clotting and bone mineralization. The Healthy Origins supplement features the MK-7 form, the long-chain variant with a longer half-life, allowing for a physiologically relevant single daily dose.

Health benefits of vitamin K2

According to the European Food Safety Authority (EFSA), vitamin K contributes to normal blood clotting and the maintenance of normal bones. The MK-7 form is the most studied in research for its ability to activate osteocalcin (bone protein) and matrix Gla protein (MGP), which helps maintain the flexibility of soft tissues. By supporting these processes, vitamin K2 complements the action of vitamin D3, helping calcium to be directed appropriately to the bones and not accumulate in unwanted places.*

How much vitamin K2 do you need? Recommended dosage

The recommended daily dose of vitamin K is not officially established in Europe, but studies with MK-7 typically use between 90 and 100 mcg per day. This supplement provides 100 mcg per vegetable capsule, a sufficient amount to activate vitamin K-dependent proteins. It is recommended to take one capsule daily with a meal containing fat, as vitamin K2 is fat-soluble and its absorption is improved in the presence of lipids. For people taking anticoagulants such as warfarin, it is essential to consult a doctor before using any vitamin K supplement.

Differences between MK-7 and MK-4

There are two main forms of vitamin K2: MK-4 (menaquinone-4) and MK-7 (menaquinone-7). MK-4 has a short half-life and requires multiple doses per day to maintain stable levels. In contrast, MK-7 has a half-life of approximately 72 hours, allowing for a single daily dose with sustained effects. In addition, MK-7 is the form used in most clinical studies on bone and cardiovascular health. Healthy Origins opts for MK-7 to offer efficient and practical supplementation.

How to choose the best vitamin K2 supplement

When selecting a vitamin K2 supplement, consider the form (MK-7 is preferable for its duration), purity (no unnecessary additives), and certifications. This product is non-GMO, gluten-free, and manufactured under cGMP standards. The capsules are vegetable, suitable for vegetarians and vegans. In addition, Healthy Origins verifies the potency of each batch through third-party testing, as recognized by ConsumerLab. Associating vitamin K2 with vitamin D3 can enhance its benefits, as D3 increases calcium absorption and K2 directs it to the appropriate tissues.

Possible side effects and contraindications

Vitamin K2 is generally safe at recommended doses. However, it can interfere with anticoagulant medications (e.g., warfarin). If you are taking these drugs, consult your doctor before starting supplementation. No significant adverse effects have been reported in healthy individuals at doses up to 100 mcg/day. This product is a food supplement and should not be used as a substitute for a balanced diet.
