Unlike vitamin K1 (phylloquinone), which is mainly found in leafy green vegetables, K2 is naturally produced in the body and is also present in fermented foods such as natto. Its main function is to activate proteins that help fix calcium in bones and teeth, preventing it from being deposited in arteries and soft tissues. This Spring Valley supplement offers 100 mcg of vitamin K2 (as menaquinone-7) per softgel, in a convenient 60-count format. Menaquinone-7 (MK-7) is the most bioavailable form of vitamin K2 with the longest half-life, allowing for sustained release in the body.\u003c\/p\u003e\u003ch2\u003eHealth benefits of vitamin K2\u003c\/h2\u003e\u003cp\u003eAccording to the European Food Safety Authority (EFSA), vitamin K contributes to the maintenance of normal bones and normal blood coagulation. These benefits are based on broad scientific consensus. Vitamin K2 activates osteocalcin, a protein that fixes calcium in the bone matrix, which helps maintain bone density and strength. In addition, it activates MGP (Matrix Gla Protein), which inhibits arterial calcification, thus promoting cardiovascular health. Consuming enough vitamin K2 is especially important for people with low dietary intake, those over 50 years of age, or those taking medications that interfere with the absorption of fat-soluble vitamins. It can also be beneficial for athletes and people with high physical activity, as it contributes to bone and muscle recovery.\u003c\/p\u003e\u003ch2\u003eHow much vitamin K2 do you need? Recommended dose\u003c\/h2\u003e\u003cp\u003eThe recommended daily dose of vitamin K for adults in the EU is approximately 70-80 mcg, although there is no specific reference intake for K2. This product provides 100 mcg per capsule, which largely covers daily needs. The usual dose is one capsule per day, preferably with a meal containing fat to improve absorption, as vitamin K2 is fat-soluble. For optimal assimilation, it is recommended to take it with the main meal or with an omega-3 supplement. If you are taking anticoagulants (such as warfarin), consult your doctor before supplementing with vitamin K, as it may interfere with the medication. People with malabsorption disorders should also consult a healthcare professional.\u003c\/p\u003e\u003ch2\u003eDifferences between vitamin K1 and K2\u003c\/h2\u003e\u003cp\u003eVitamin K1 (phylloquinone) is found in green vegetables such as spinach, broccoli, and kale, and is essential for blood coagulation in the liver. Vitamin K2 (menaquinone) is synthesized in the intestine by bacteria and is found in fermented foods such as natto, aged cheeses, and animal products such as liver. K2 has a longer half-life and is better distributed in extrahepatic tissues, making it more effective for bone and cardiovascular health. Within K2, menaquinone-7 (MK-7) is the most bioavailable and long-lasting form, which is used in this supplement. MK-7 is obtained from the fermentation of soy (natto) or synthetically, offering high purity and efficacy.\u003c\/p\u003e\u003ch2\u003eHow to choose the best vitamin K2 supplement\u003c\/h2\u003e\u003cp\u003eWhen choosing a vitamin K2 supplement, consider the form (MK-7 is preferred for its bioavailability), the dosage (100 mcg is a common and effective dose), and the quality of the product. This Spring Valley supplement is formulated with menaquinone-7 in softgels for optimal absorption. Softgels facilitate intake and protect the active ingredient from degradation. It is gluten-free, non-GMO, and suitable for vegetarians (although check the label if it contains animal-derived gelatin). Store in a cool, dry place, below 25 °C, and keep the container tightly closed. The expiration date is indicated on the package. Always check the integrity of the seal before use.\u003c\/p\u003e\u003ch2\u003eWhy combine vitamin K2 with vitamin D?\u003c\/h2\u003e\u003cp\u003eVitamin D and vitamin K2 work synergistically to optimize calcium metabolism. While vitamin D increases calcium absorption in the intestine, vitamin K2 directs that calcium to the bones and teeth, preventing it from accumulating in the arteries and kidneys. Many experts recommend combining both vitamins for complete bone and cardiovascular health. If you are taking a vitamin D supplement, consider adding this K2 supplement to maximize its benefits. It can be taken at the same time of day.\u003c\/p\u003e\u003ch2\u003ePossible side effects and contraindications\u003c\/h2\u003e\u003cp\u003eVitamin K2 is generally safe and well-tolerated at recommended doses. No toxicity levels have been established, but very high doses (greater than 1000 mcg) could cause mild digestive discomfort or allergic reactions in sensitive individuals. It is contraindicated in people taking anticoagulants such as warfarin (Coumadin) without medical supervision, as vitamin K antagonizes its effect. Pregnant or breastfeeding women should consult a healthcare professional before using any supplement. In case of scheduled surgery, discontinue the supplement at least two weeks beforehand if you are taking anticoagulants.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThis product is a food supplement and should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose. Keep out of reach of children.\u003c\/em\u003e\u003c\/p\u003e","brand":"Spring Valley","offers":[{"title":"Default Title","offer_id":48764775694490,"sku":null,"price":26.68,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/vitaminaspain.es\/es\/products\/spring-valley-vitamina-k2-100-mcg-b00q3hi8qw","provider":"vitaminaspain","version":"1.0","type":"link"}
