Unlike vitamin K1 (phylloquinone), which is found primarily in green leafy vegetables and is involved in blood clotting, vitamin K2 activates proteins that direct calcium to the bones and teeth, preventing its accumulation in the arteries. The MK-7 (menaquinone-7) form is the most bioavailable and long-acting, making it the preferred option in supplementation. This product contains MenaQ7®, a patented form of MK-7 backed by clinical studies, with 180 mcg per vegetable capsule.\u003c\/p\u003e\u003ch2\u003eHealth benefits of vitamin K2\u003c\/h2\u003e\u003cp\u003eVitamin K2 contributes to key functions in the body. According to the European Food Safety Authority (EFSA), vitamin K contributes to the maintenance of normal bones and normal blood clotting. By activating osteocalcin, it promotes the binding of calcium to the bone matrix, helping to maintain bone density and strength. In addition, it activates MGP protein (matrix Gla protein), which inhibits the calcification of blood vessels, which may support cardiovascular health. Although the effects on the heart do not have an EFSA-approved claim, observational studies suggest a possible benefit in arterial elasticity. As a food supplement, its regular use can contribute to balanced bone metabolism.\u003c\/p\u003e\u003ch2\u003eHow much vitamin K2 do you need? Recommended dosage\u003c\/h2\u003e\u003cp\u003eThe daily dose of vitamin K2 varies according to age, health status and diet. For adults, the adequate intakes (AI) established by the EFSA are 70 mcg per day for women and 70 mcg for men (in the form of phylloquinone). However, the optimal dose of K2 MK-7 in supplements is usually 100 to 200 mcg per day. This product provides 180 mcg per capsule, a dose that has been used in clinical studies to support bone and cardiovascular health. Taking one capsule a day with a meal containing fat improves absorption. No maximum tolerable intake levels (UL) have been established for vitamin K, as no significant adverse effects have been observed with high doses. However, it is always advisable to consult a healthcare professional before starting any supplementation.\u003c\/p\u003e\u003ch2\u003eDifferences between vitamin K1 and K2\u003c\/h2\u003e\u003cp\u003eVitamin K1 (phylloquinone) is found in green leafy vegetables such as spinach, broccoli and lettuce, and is essential for blood clotting. Vitamin K2 (menaquinone) is produced by intestinal bacteria and is found in fermented foods such as natto (fermented soybeans) and in animal products such as liver and cheeses. Within K2, there are subtypes: MK-4 (short-chain, present in some animal foods) and MK-7 (long-chain, with a longer half-life in the blood). MK-7 is better absorbed and remains active longer, allowing for once-a-day dosing. MenaQ7® is a natural form of MK-7 derived from natto, GMO and gluten-free, and with studies supporting its efficacy.\u003c\/p\u003e\u003ch2\u003eHow to choose the best vitamin K2 supplement\u003c\/h2\u003e\u003cp\u003eWhen selecting a vitamin K2 supplement, it is key to consider the form and quality. MK-7 is the most recommended for its bioavailability and duration of action. Look for brands that use patented ingredients such as MenaQ7®, which guarantee purity and potency. This supplement has undergone third-party laboratory testing, ensuring that it meets quality standards. In addition, it is manufactured in GMP and FDA-registered facilities in the USA (although the product is marketed in Spain, the quality of the process is an indicator of confidence). It is gluten-free, GMO-free and packaged in vegetable capsules suitable for vegetarians and vegans. Store in a cool, dry place, and keep out of reach of children.\u003c\/p\u003e\u003ch2\u003ePossible side effects and contraindications\u003c\/h2\u003e\u003cp\u003eVitamin K2 is generally safe and well tolerated. No significant adverse effects have been reported with doses up to 360 mcg per day. However, people taking anticoagulants (such as warfarin) should consult their doctor before using vitamin K supplements, as it may interfere with the medication. It is also not recommended in case of soy allergy (MenaQ7 is derived from fermented soy). This product is a food supplement and should not be used as a substitute for a balanced diet. If you are pregnant, breastfeeding or have any medical condition, consult a healthcare professional before consumption.\u003c\/p\u003e","brand":"Truevantage Nutrition","offers":[{"title":"Default Title","offer_id":48765013524634,"sku":null,"price":42.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/4831\/0170\/files\/71_O4SXTG3S._AC_SL1500.jpg?v=1784491917","url":"https:\/\/vitaminaspain.es\/es\/products\/suplemento-vitamina-k2-mk7-180-mcg-menaq7-b01fir33fs","provider":"vitaminaspain","version":"1.0","type":"link"}
