biophix Vitamina K2 MK-7 300mcg - 120 Cápsulas Veganas

What is vitamin K2 MK-7 and why is it important?

Vitamin K is a fat-soluble nutrient that exists in two main forms: K1 (phylloquinone) and K2 (menaquinone). Vitamin K2, particularly the MK-7 (menaquinone-7) subform, stands out for its bioavailability and long half-life in the body. Unlike K1, which is found primarily in green leafy vegetables, K2 is obtained from fermented foods and, to a lesser extent, from animal products. The biophix Vitamin K2 MK-7 supplement provides 300 mcg per capsule of this highly active form, made from vegan sources. Vitamin K2 plays a crucial role in activating proteins that regulate blood clotting and calcium metabolism, thus supporting bone and cardiovascular health.

Health benefits of vitamin K2

Vitamin K contributes to normal blood clotting and the maintenance of normal bones, according to health claims approved by the European Food Safety Authority (EFSA). The MK-7 form is especially effective in activating osteocalcin, a protein that fixes calcium in the bone matrix, and matrix Gla protein (MGP), which inhibits arterial calcification. This means that an adequate intake of vitamin K2 helps calcium to be directed towards the bones and not deposited in the arteries. In addition, by promoting proper calcium utilization, it helps maintain bone density, which is particularly relevant in postmenopausal women and older people. Regular consumption of vitamin K2 has also been associated with improved arterial elasticity and a lower risk of vascular stiffness.

How much vitamin K2 do you need? Recommended dose

Daily vitamin K requirements are not precisely established, but adequate intakes range from 90 to 120 mcg for adults. However, vitamin K2 MK-7 has significantly superior absorption and retention to K1, so higher doses may be beneficial. Each biophix capsule provides 300 mcg of MK-7, an amount higher than many supplements on the market. This dose is considered safe and effective for promoting bone and cardiovascular health. The tolerable upper intake level (UL) has not been defined for vitamin K, as no significant adverse effects have been observed with high doses. However, it is recommended to consult a healthcare professional before starting any supplementation, especially if taking anticoagulants.

Differences between MK-4 and MK-7

There are two main forms of vitamin K2: MK-4 (menaquinone-4) and MK-7. MK-4 has a short half-life (a few hours) and is found in small amounts in animal foods such as liver and egg yolk. In contrast, MK-7, present in natto (fermented soybeans), has a half-life of approximately 72 hours, which allows for stable blood levels with a single daily dose. In addition, MK-7 is more effective in activating vitamin K-dependent proteins outside the liver, such as osteocalcin and MGP. Therefore, most experts recommend MK-7 for bone and cardiovascular health. The biophix supplement uses MK-7, ensuring optimal bioavailability and efficacy.

Possible side effects and contraindications

Vitamin K2 is generally safe and well-tolerated. However, people taking anticoagulant medications (such as warfarin or acenocoumarol) should avoid vitamin K supplementation without medical supervision, as it may interfere with the drug's action. Likewise, very high doses could cause mild digestive discomfort in some people. There is no established maximum intake level, but it is recommended not to exceed the dose indicated on the package.
