Vital Nutrients Vitamina K2-7 (MK-7) - 60 Cápsulas Veganas

What is Vitamin K2-7 and why is it important?

Vitamin K2-7, also known as menaquinone-7 (MK-7), is a form of vitamin K that plays a key role in calcium metabolism. Unlike vitamin K1 (phylloquinone), which is mainly found in green leafy vegetables and is involved in blood clotting, K2-7 has a longer half-life and is better distributed throughout the body, making it the ideal form to support bone and cardiovascular health. This Vital Nutrients supplement provides 100 mcg of MK-7 per capsule, in a vegan, hypoallergenic, and non-GMO formula.

Benefits of Vitamin K2-7 for cardiovascular and bone health

Vitamin K2-7 contributes to the maintenance of normal bones and normal blood clotting, according to the European Food Safety Authority (EFSA). By activating osteocalcin and matrix Gla protein (MGP), it helps direct calcium to bones and teeth, preventing it from depositing in arteries. In this way, it supports vascular elasticity and heart health. In addition, by maintaining healthy bone metabolism, it can be especially beneficial for postmenopausal women and older people.

How much vitamin K2-7 do you need? Recommended dose

The recommended daily dose of vitamin K is not officially established, but studies typically use between 100 and 200 mcg of MK-7 per day. Vital Nutrients offers 100 mcg per capsule, an amount supported by research to maintain adequate vitamin K levels and support bone and cardiovascular health. It is recommended to take one capsule daily with a meal containing fats to optimize absorption, as vitamin K is fat-soluble. Always consult a healthcare professional before starting any supplementation, especially if you are taking anticoagulants such as warfarin.

Differences between vitamin K1 and K2 (menaquinone-7)

Vitamin K comes in two main forms: K1 (phylloquinone) and K2 (menaquinones). K1 is found in green leafy vegetables and is mainly used for blood clotting. K2, particularly menaquinone-7 (MK-7), is produced by bacteria and is found in fermented foods such as natto (fermented soybeans). MK-7 has a much longer half-life (approximately 72 hours) than K1 (only a few hours), allowing for more uniform distribution and sustained levels in the body. In addition, MK-7 is more effective at activating vitamin K-dependent proteins outside the liver, such as osteocalcin in bones and MGP in arteries. Therefore, many experts consider K2-7 to be the optimal form for supplementation.

How to choose the best vitamin K2-7 supplement

When choosing a vitamin K2-7 supplement, it is important to consider the form (MK-7), source (vegan or not), certifications, and purity. This Vital Nutrients product is 100% vegan, as MK-7 is obtained through natto fermentation (soybeans). It is free of gluten, dairy, soy (as an allergen), GMOs, and artificial excipients. In addition, the brand performs quality tests in independent laboratories to guarantee potency and purity. The capsule presentation facilitates dosage and absorption, especially if taken with fatty foods.

Possible side effects and contraindications

Vitamin K2-7 is considered safe at recommended doses. However, people taking anticoagulants (such as warfarin) should consult their doctor before use, as vitamin K can interfere with the medication. No serious adverse effects have been reported with doses up to 360 mcg per day. As with any supplement, it is important to follow the instructions on the package. This product is a food supplement and should not be used as a substitute for a balanced diet.
