Unlike vitamin K1 (phylloquinone), which is found primarily in green leafy vegetables, K2 is obtained from fermented foods and is produced by intestinal bacteria. It comes in various subforms, the most studied being MK-4 and MK-7.\u003c\/p\u003e\u003cp\u003eMK-4 is a short-chain form found in animal products such as liver and egg yolk, while MK-7 is long-chain and comes from natto (fermented soybeans). Both contribute to activating vitamin K-dependent proteins, such as osteocalcin (for bone mineralization) and matrix Gla protein (for arterial elasticity).\u003c\/p\u003e\u003ch2\u003eHealth Benefits\u003c\/h2\u003e\u003cp\u003eVitamin K contributes to normal blood clotting and the maintenance of normal bones. This vitamin K2 supplement provides a potent dose of both forms to support these physiological processes.\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eNormal clotting:\u003c\/strong\u003e Vitamin K activates clotting factors in the liver, helping to maintain an adequate hemostatic response.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBone health:\u003c\/strong\u003e By activating osteocalcin, vitamin K promotes the binding of calcium to the bone matrix, which contributes to bone density and strength.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003eThese benefits are backed by scientific research and are part of the authorized health claims in the European Union.\u003c\/p\u003e\u003ch2\u003eWhy choose this MK-4 and MK-7 combination?\u003c\/h2\u003e\u003cp\u003eThis product combines two complementary forms of vitamin K2: 15,000 mcg of MK-4 (high dose) and 60 mcg of MK-7 (potent and long-lasting). MK-4 has a short half-life and acts quickly, while MK-7 remains in the body longer, offering a sustained effect. This combination emulates the doses used in Japanese and European studies, providing a comprehensive approach.\u003c\/p\u003e\u003cp\u003eAdditionally, the capsules contain a minimum of excipients, only those necessary to fill the size #4 capsule. Purity is pharmaceutical grade: MK-4 has less than 1% CIS form (inactive isomer) and MK-7 less than 4%. The product is verified by external laboratories registered with the FDA and complies with GMP (Good Manufacturing Practices) regulations.\u003c\/p\u003e\u003cp\u003eClinical studies have shown that the combination of MK-4 and MK-7 can optimize vitamin K levels in the body, improving the activation of dependent proteins. MK-7, in particular, has been associated with better bioavailability and a longer half-life, allowing for once-daily dosing.\u003c\/p\u003e\u003ch2\u003eHow to take vitamin K2?\u003c\/h2\u003e\u003cp\u003eThe recommended dose is one capsule daily, preferably with a meal containing fat to improve absorption (due to its fat-soluble nature). Do not exceed the indicated daily dose. Each package contains 90 vegetable capsules, equivalent to a three-month supply.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e If you are taking anticoagulants (such as warfarin), consult your doctor before using this supplement, as vitamin K can interfere with their mechanism of action.\u003c\/p\u003e\u003ch2\u003ePossible side effects and contraindications\u003c\/h2\u003e\u003cp\u003eVitamin K2 is generally well tolerated. At high doses, some people may experience mild digestive discomfort. Its use is not recommended in pregnant or breastfeeding women without medical supervision. People with clotting disorders or liver diseases should consult a healthcare professional before consumption.\u003c\/p\u003e\u003cp\u003eThis product is soy-free, making it suitable for people with soy allergies or sensitivities.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWhat is the difference between vitamin K1 and K2?\u003c\/h3\u003e\u003cp\u003eK1 (phylloquinone) is found in green vegetables and is mainly used for clotting. K2 (menaquinone) has better bioavailability and a longer half-life, and plays a more important role in bone and cardiovascular health.\u003c\/p\u003e\u003ch3\u003eCan I take this supplement with vitamin D and calcium?\u003c\/h3\u003e\u003cp\u003eYes, vitamin K2 acts synergistically with vitamin D and calcium. Vitamin D improves calcium absorption, and K2 helps direct it to the bones instead of depositing in the arteries. However, consult a professional to adjust doses.\u003c\/p\u003e\u003ch3\u003eIs it necessary to store it in the refrigerator?\u003c\/h3\u003e\u003cp\u003eNo, but it is recommended to store it in a cool, dry place, protected from direct sunlight.\u003c\/p\u003e\u003ch3\u003eHow long does it take to notice the effects?\u003c\/h3\u003e\u003cp\u003eEffects may vary by individual. Some people may notice improvements in bone and cardiovascular health after several weeks of continuous use, while others may need more time. Regular use is recommended to obtain the best results.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThis product should not be used as a substitute for a balanced diet.
