That doesn\u2019t make MK-4 unimportant, though. It has some interesting research behind it too, especially for bone health, but the doses used in studies are often much higher than what you\u2019ll find in a typical supplement.<\/p>\n<p>So, which one is actually better? Let\u2019s look at the main differences and what the research says about bones, osteoporosis and heart health.<\/p>\n<h2>MK-4 vs MK-7: What\u2019s the difference?<\/h2>\n<p>Vitamin K2 isn\u2019t just one vitamin. It\u2019s a group of related forms called <strong>menaquinones<\/strong> \u2013 simply the scientific name for the different forms of vitamin K2. This is where the \u201cMK\u201d comes from. MK-4 and MK-7 are the two forms you\u2019re most likely to come across in supplements.<\/p>\n<p>One of the biggest differences between them is how long they stay in the blood. MK-4 is cleared fairly quickly, while MK-7 remains in circulation for longer. In <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3502319\/\" target=\"_blank\" rel=\"noopener\">research directly comparing MK-4 and MK-7<\/a>, MK-7 built up in the blood with regular use, while MK-4 did not.<\/p>\n<p>There is another interesting difference. Our bodies can convert other forms of vitamin K, including vitamin K1 from food, into <strong>MK-4<\/strong>. Our tissues don\u2019t make MK-7 in the same way. MK-7 is produced by bacteria and is particularly abundant in fermented foods such as natto.<\/p>\n<h3>MK-4 vs MK-7 at a glance<\/h3>\n<figure class=\"wp-block-table\">\n<table>\n<tbody>\n<tr>\n<th\/>\n<th><strong>MK-4<\/strong><\/th>\n<th><strong>MK-7<\/strong><\/th>\n<\/tr>\n<tr>\n<td><strong>What is it?<\/strong><\/td>\n<td>A form of vitamin K2<\/td>\n<td>A form of vitamin K2<\/td>\n<\/tr>\n<tr>\n<td><strong>How long it stays in the blood<\/strong><\/td>\n<td>Relatively short time<\/td>\n<td>Much longer<\/td>\n<\/tr>\n<tr>\n<td><strong>Can our body make it?<\/strong><\/td>\n<td>Yes.

In <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3502319\/\" target=\"_blank\" rel=\"noopener\">a direct comparison of MK-4 and MK-7<\/a>, MK-7 built up in the blood with regular use, while MK-4 did not.<\/p>\n<p>It also seems to work at fairly small doses. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/22289649\/\" target=\"_blank\" rel=\"noopener\">Research looking at different doses of MK-7<\/a> found that even lower amounts were enough to improve signs that vitamin K was being used properly in the body.<\/p>\n<h3>But that doesn\u2019t make MK-4 a bad choice<\/h3>\n<p>MK-4 is still an important form of vitamin K2, and our bodies make it themselves. The main difficulty is that much of the research showing benefits from MK-4 used much higher doses than you\u2019ll find in a typical supplement.<\/p>\n<p>So, for general supplement use, <strong>MK-7 is usually the more practical choice<\/strong>. But that doesn\u2019t automatically mean it is better for every purpose, especially when we start looking at bone and heart health.<\/p>\n<h2>MK-4 vs MK-7 for bone health and osteoporosis<\/h2>\n<p>Vitamin K is important for healthy bones because it activates <strong>osteocalcin<\/strong>, a protein that helps calcium become part of the bone structure. This is one reason K2 has attracted so much interest for bone health and osteoporosis.<\/p>\n<h3>What does the research say about MK-7?<\/h3>\n<p>There is some promising research, particularly in postmenopausal women. In <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/23525894\/\" target=\"_blank\" rel=\"noopener\">a three-year study of 244 women<\/a>, taking 180 \u00b5g of MK-7 daily appeared to slow some of the bone loss normally seen with age, including in the spine and hip.<\/p>\n<p>But the results haven\u2019t always been consistent. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/33030563\/\" target=\"_blank\" rel=\"noopener\">Another three-year study<\/a> using 375 \u00b5g a day found that MK-7 improved the way vitamin K was being used in the body, but it didn\u2019t significantly improve bone density.<\/p>\n<p>So MK-7 may support bone health, but we can\u2019t say that taking it will necessarily increase bone density or prevent fractures.<\/p>\n<h3>What about MK-4?<\/h3>\n<p>MK-4 has also been studied quite a lot for osteoporosis, particularly in Japan. But there is one very important difference: <strong>the doses were often much higher compared with normal supplements.<\/strong><\/p>\n<p>Many of these studies used <strong>45 mg of MK-4 a day<\/strong>. Remember that:<\/p>\n<p><strong>1 mg = 1,000 \u00b5g<\/strong><\/p>\n<p>So 45 mg is actually <strong>45,000 \u00b5g<\/strong>. That\u2019s very different from the 180 \u00b5g of MK-7 used in the study above, and it means we can\u2019t assume that a supplement containing a few hundred micrograms of MK-4 will have the same effect.<\/p>\n<p>Older research also reported some very impressive reductions in fractures with MK-4, but those results need to be treated with caution. Several studies in this area were later retracted because of problems with the data, and <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/30734066\/\" target=\"_blank\" rel=\"noopener\">a more recent review<\/a> found that while MK-4 may help with bone density in the spine, it\u2019s still not clear whether it actually prevents fractures.<\/p>\n<h3>Which is better if you have osteoporosis?<\/h3>\n<p>At the moment, <strong>there isn\u2019t enough good evidence to say that MK-4 or MK-7 is clearly better for osteoporosis<\/strong>.<\/p>\n<p>High-dose MK-4 has been studied for many years, while MK-7 has some encouraging research at much smaller, more typical supplement doses. But neither form has strong enough evidence to replace proper osteoporosis treatment.<\/p>\n<h2>Which form looks better for heart health?<\/h2>\n<p>Vitamin K also activates a protein called <strong>matrix Gla protein (MGP)<\/strong>, which helps stop calcium building up in places where it shouldn\u2019t, including the walls of blood vessels. This is why researchers have been interested in whether vitamin K2 could help protect the heart and arteries.<\/p>\n<h3>What does the research say about MK-7?<\/h3>\n<p>Most of the human research in this area has looked at MK-7.<\/p>\n<p>In <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25694037\/\" target=\"_blank\" rel=\"noopener\">a three-year study looking at artery flexibility<\/a>, taking 180 \u00b5g of MK-7 a day improved some measures of how flexible the arteries were, especially in women whose arteries were stiffer at the start of the study.<\/p>\n<p>But not every study has found a clear benefit. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/35465686\/\" target=\"_blank\" rel=\"noopener\">A 2022 study looked at calcium build-up in the aortic valve<\/a> \u2013 the valve that controls blood flow from the heart into the main artery. MK-7 improved signs that vitamin K was being used properly in the body, but it didn\u2019t significantly slow the calcium build-up itself.<\/p>\n<p>More recently, <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/42268593\/\" target=\"_blank\" rel=\"noopener\">a 2026 study in people with coronary artery disease<\/a> found that calcium build-up in the arteries supplying the heart progressed more slowly in people taking MK-7. That\u2019s encouraging, but it still doesn\u2019t tell us whether MK-7 can actually prevent heart attacks or heart disease.<\/p>\n<h3>And MK-4?<\/h3>\n<p>There is much less human research on MK-4 and heart health. So, if this is your main reason for choosing between the two, <strong>MK-7 currently has more evidence behind it<\/strong>.<\/p>\n<p>That doesn\u2019t mean it\u2019s proven to protect the heart, though. The research is still developing, and neither form should be seen as a treatment for heart disease.<\/p>\n<h2>What dose of MK-4 or MK-7 should you take?<\/h2>\n<p>There isn\u2019t an official recommended daily amount specifically for MK-4 or MK-7, so the doses you see on supplements can vary quite a lot.<\/p>\n<p>For <strong>MK-7<\/strong>, many studies have used around <strong>90\u2013360 \u00b5g a day<\/strong>, and <strong>180 \u00b5g<\/strong> is one of the better-studied amounts.<\/p>\n<p>For <strong>MK-4<\/strong>, the picture is less straightforward. Some studies have used lower doses, but many of the well-known osteoporosis studies used <strong>45 mg a day<\/strong>, which is the same as <strong>45,000 \u00b5g<\/strong>.<\/p>\n<h3>So what does that mean in practice?<\/h3>\n<p>If you\u2019re choosing an everyday MK-7 supplement, something in the region of <strong>90\u2013180 \u00b5g a day<\/strong> is much closer to the amounts commonly used in supplements and research. There\u2019s no good reason to assume that taking more will give you more benefit.<\/p>\n<p>Vitamin K also has a good safety record and there is currently <strong>no official upper daily limit<\/strong> for vitamin K. Still, I wouldn\u2019t use very high-dose MK-4, such as the 45 mg used in osteoporosis studies, unless it had been specifically recommended by a healthcare professional.<\/p>\n<p>And if you take warfarin or another medicine that works by blocking vitamin K, check with your doctor before taking either form of K2.<\/p>\n<h2>MK-4 vs MK-7: The bottom line<\/h2>\n<p><strong>For most people choosing an everyday vitamin K2 supplement, MK-7 is probably the more practical option.<\/strong> It lasts longer in the body and has more human research at the sort of doses commonly found in supplements.<\/p>\n<p>The research on bone and heart health is promising but not clear-cut, so I\u2019d see K2 as something that may support health rather than a proven treatment for osteoporosis or heart disease.<\/p>\n<h2>FAQs<\/h2>\n<h3>Is MK-4 or MK-7 better for teeth?<\/h3>\n<p>We don\u2019t really know yet. There isn\u2019t good human research showing that one form is better than the other for teeth.<\/p>\n<p>There is some interest in vitamin K2 and dental health, and <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/37998429\/\" target=\"_blank\" rel=\"noopener\">one small study found lower K2 levels in people with gum disease<\/a>, but that doesn\u2019t prove that taking K2 will improve teeth or gums.<\/p>\n<h3>Does MK-4 increase testosterone?<\/h3>\n<p>There is some interesting research here, but so far it mainly comes from animals. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21914161\/\" target=\"_blank\" rel=\"noopener\">One study found that MK-4 increased testosterone production in rats<\/a>, but we don\u2019t have good human evidence showing that taking MK-4 raises testosterone in men.<\/p>\n<h3>Can I take MK-4 and MK-7 together?<\/h3>\n<p>Yes. Some K2 supplements contain both forms.<\/p>\n<p>Some supplements contain both forms, but we don\u2019t have good evidence showing that taking both works better than MK-7 on its own.<\/p>\n<h3>Is vitamin K2 safe to take?<\/h3>\n<p>For most people, vitamin K2 appears to be well tolerated at the amounts commonly found in supplements. There is currently <strong>no official upper daily limit for vitamin K<\/strong>, although that doesn\u2019t mean taking very large doses will give you extra benefit.<\/p>\n<p>The main exception is if you take <strong>warfarin or another medicine that works by blocking vitamin K<\/strong>. Vitamin K supplements can affect how these medicines work, so speak to your doctor before taking K2. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/23530987\/\" target=\"_blank\" rel=\"noopener\">Even fairly small doses of MK-7 have been shown to affect this type of blood-thinning medicine<\/a>.<\/p>\n<h3>Should you take vitamin K2 with vitamin D?<\/h3>\n<p>You can, and the two vitamins are often combined in supplements.<\/p>\n<p>Vitamin D helps your body absorb calcium, while vitamin K activates proteins involved in using calcium in bones and other tissues. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32219282\/\" target=\"_blank\" rel=\"noopener\">Research combining vitamin D and vitamin K<\/a> suggests there may be some benefit for bone health, but we don\u2019t have enough evidence to say that everyone taking vitamin D also needs K2.<\/p>\n<p>There also isn\u2019t one proven combination or dose that is right for everyone.<\/p>\n<h3>Should K2 be taken with food?<\/h3>\n<p>Yes, ideally. Vitamin K is <strong>fat-soluble<\/strong>, which means it is absorbed along with fat from food.<\/p>\n<p>Taking your K2 supplement with a meal containing some fat \u2013 for example yoghurt, eggs, olive oil, nuts or avocado \u2013 makes sense and may help with absorption.<\/p>\n<\/p><\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script><br \/>\n<br \/><a href=\"https:\/\/www.behealthynow.co.uk\/nutrition\/vitamin-k2-mk4-vs-mk7\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>MK-4 and MK-7 are both forms of vitamin K2, but they don\u2019t behave in quite the same way in the body.
