Less prominent than some vitamins, it nevertheless has a major impact, particularly for active people and athletes.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"500\" src=\"https:\/\/getindya.com\/wp-content\/uploads\/alimentos-vitamina-k.jpg\" alt=\"vitamin K\" class=\"wp-image-31536\" title=\"\" srcset=\"https:\/\/getindya.com\/wp-content\/uploads\/alimentos-vitamina-k.jpg 1000w, https:\/\/getindya.com\/wp-content\/uploads\/alimentos-vitamina-k-300x150.jpg 300w, https:\/\/getindya.com\/wp-content\/uploads\/alimentos-vitamina-k-768x384.jpg 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What is vitamin K, and why does it matter?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><br>Vitamin K is a fat-soluble vitamin essential for blood clotting, bone health and cardiovascular protection.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It activates proteins with vital functions, including preventing bleeding, strengthening bones and limiting arterial calcification.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">There are two main forms:&nbsp;<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Vitamin K1, or phylloquinone<\/strong>, found in leafy green vegetables.<\/li>\n\n\n\n<li><strong>Vitamin K2, or menaquinone<\/strong>, found in fermented foods and animal products.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Main functions of vitamin K<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><br>Vitamin K has important roles across different tissues. The main ones include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Blood clotting: <\/strong>essential for producing clotting proteins, including prothrombin.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Deficiency can cause frequent bruising, nosebleeds, bleeding gums and even internal bleeding.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Bone health: <\/strong>K2 activates osteocalcin, enabling calcium to bind correctly to bone. Without activation, calcium may fail to reach bone and accumulate in tissues such as arteries instead.&nbsp;<\/li>\n\n\n\n<li><strong>Cardiovascular protection: <\/strong>vitamin K also activates MGP, a protein preventing calcium deposition in arteries. This helps maintain arterial elasticity and prevent atherosclerosis.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Vitamin K therefore regulates calcium, helping it reach bones and preventing accumulation elsewhere.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vitamin K1 vs K2<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">K1 comes mainly from leafy greens and is associated with clotting. K2 occurs in animal and fermented foods and helps direct calcium to bones while preventing arterial deposition.<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Daily recommendations by age and life stage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Adult men are generally advised to consume <strong>120 mcg\/day <\/strong>and women <strong>90 mcg\/day.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These remain unchanged during pregnancy or breastfeeding unless a doctor advises otherwise.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Foods rich in vitamin K1 (phylloquinone)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">K1 is the most common dietary form. Plant sources include<strong> <\/strong>spinach, kale, chard, dark lettuce, broccoli, Brussels sprouts, parsley, basil, coriander, soya and olive oils, kiwi, grapes, peas and avocado.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Darker green vegetables generally contain more vitamin K.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"999\" height=\"667\" src=\"https:\/\/getindya.com\/wp-content\/uploads\/vitamina-k.jpg\" alt=\"foods rich in vitamin K\" class=\"wp-image-31540\" title=\"\" srcset=\"https:\/\/getindya.com\/wp-content\/uploads\/vitamina-k.jpg 999w, https:\/\/getindya.com\/wp-content\/uploads\/vitamina-k-300x200.jpg 300w, https:\/\/getindya.com\/wp-content\/uploads\/vitamina-k-768x513.jpg 768w\" sizes=\"auto, (max-width: 999px) 100vw, 999px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Foods rich in vitamin K2 (menaquinone)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Sources include natto, or fermented soya, kefir, sauerkraut, miso, egg yolks, liver, aged cheeses such as Gouda and Edam, and salmon.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><br>What affects vitamin K absorption?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">The role of dietary fats<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><br><strong>Vitamin K is absorbed better alongside healthy fats<\/strong>. Pair it with avocado, olive oil, nuts, seeds or oily fish to maximise its use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Antibiotics and digestive conditions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Prolonged antibiotic use may disrupt gut flora and natural K2 production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conditions impairing fat absorption, including Crohn&#8217;s disease, coeliac disease or bariatric surgery, may also reduce vitamin K absorption.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><br>Who needs to monitor vitamin K intake?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">People taking anticoagulants or warfarin<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><br>Vitamin K can interfere with some anticoagulants. Do not eliminate it: maintain consistent intake and regular medical monitoring so medication doses can be adjusted.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why medical supervision matters<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Medical monitoring is essential: check INR and adjust medication according to diet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Keep vitamin K intake consistent and controlled with professional guidance rather than eliminating it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Everyday ways to include vitamin K foods<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Add a daily portion of green vegetables to salads, stir-fries or soups.<\/li>\n\n\n\n<li>Use extra virgin olive oil as your main cooking fat.<\/li>\n\n\n\n<li>Include fermented foods such as kefir, sauerkraut or miso.&nbsp;<\/li>\n\n\n\n<li>Choose aged cheeses or eggs.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion:<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Vitamin K supports overall health. Adequate intake through a varied diet can make a meaningful difference to wellbeing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References:<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/scielo.isciii.es\/scielo.php?pid=S1889-836X2015000100008&amp;script=sci_abstract\" target=\"_blank\" rel=\"noopener\">https:\/\/scielo.isciii.es\/scielo.php?pid=S1889-836X2015000100008&amp;script=sci_abstract<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/ods.od.nih.gov\/factsheets\/VitaminK-HealthProfessional\/\" target=\"_blank\" rel=\"noopener\">https:\/\/ods.od.nih.gov\/factsheets\/VitaminK-HealthProfessional\/<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.msdmanuals.com\/es\/professional\/trastornos-nutricionales\/deficiencia-dependencia-e-intoxicaci%C3%B3n-vitam%C3%ADnica\/deficiencia-de-vitamina-k\" target=\"_blank\" rel=\"noopener\">https:\/\/www.msdmanuals.com\/es\/professional\/trastornos-nutricionales\/deficiencia-dependencia-e-intoxicaci%C3%B3n-vitam%C3%ADnica\/deficiencia-de-vitamina-k<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.cigna.com\/es-us\/knowledge-center\/hw\/warfarina-y-vitamina-k-abo1632\" target=\"_blank\" rel=\"noopener\">https:\/\/www.cigna.com\/es-us\/knowledge-center\/hw\/warfarina-y-vitamina-k-abo1632<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/lpi.oregonstate.edu\/es\/mic\/vitaminas\/vitamina-K\" target=\"_blank\" rel=\"noopener\">https:\/\/lpi.oregonstate.edu\/es\/mic\/vitaminas\/vitamina-K<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Vitamin K plays a fundamental role in bone health, blood clotting and cardiovascular protection.<\/p>\n","protected":false},"author":19,"featured_media":31536,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"rop_custom_images_group":[],"rop_custom_messages_group":[],"rop_publish_now":"initial","rop_publish_now_accounts":[],"rop_publish_now_history":[],"rop_publish_now_status":"pending","footnotes":""},"categories":[213,1],"tags":[],"class_list":["post-35068","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-nutrition","category-sin-categoria"],"acf":[],"_links":{"self":[{"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/posts\/35068","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/users\/19"}],"replies":[{"embeddable":true,"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/comments?post=35068"}],"version-history":[{"count":1,"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/posts\/35068\/revisions"}],"predecessor-version":[{"id":35069,"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/posts\/35068\/revisions\/35069"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/media\/31536"}],"wp:attachment":[{"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/media?parent=35068"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/categories?post=35068"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/getindya.com\/en\/wp-json\/wp\/v2\/tags?post=35068"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
