Vitamin K2 Vitamin K2 is also a fat soluble vitamin. Researchers are discovering that vitamin K might be just as crucial to our overall health as vitamin D.2Vitamin K preserves elastin, a protein the body produces that keeps blood vessels flexible and elastic.2 The Benefits Of Partnership Many vitamins, minerals and nutrients complement each other. The combination of omega-3, vitamin D3 and vitamin K2 is an excellent example. Fat soluble vitamins D and K partner well with the essential fatty acid, omega-3, which aids in their absorption. This powerful combination may help to support our brain, joint, eye, immune, cardiovascular and bone health. Unfortunately, most of us do not get enough of these nutrients from our daily diets, so with the support of a healthcare provider, one may consider adding them into a daily supplement routine to support overall wellness.

“Should vitamin K be supplemented alongside vitamin D? - Examine”
Should vitamin K be supplemented alongside vitamin D? Save page Written by: Morgan Pfiffner, Bill Willis+ 4+ 4others Fact-checked by: Nick Milazzo, Katie Jantz+ 1+ 1other •Last Updated: October 6, 2025  Written by: Morgan Pfiffner, MS • Bill Willis, PhD+ 4others Fact-checked by: Nick Milazzo, MSc, MPH • Katie Jantz, RPh, MSc+ 1other Last Updated:October 6, 2025 It’s been suggested that supplementing vitamin K alongside vitamin D can improve both the efficacy and safety of vitamin D supplements. However, there is little direct evidence to support the practice. Efficacy Vitamin D and vitamin K both play important roles in ensuring our bones are healthy and strong,[[1]](https://examine.com/faq/should-vitamin-k-be-supplemented-alongside-vitamin-d/#ref-1) and a deficiency in either vitamin is associated with an increased risk of fracture.[[2]](https://examine.com/faq/should-vitamin-k-be-supplemented-alongside-vitamin-d/#ref-2) However, a benefit to supplementing vitamin K and D together hasn’t been consistently found. Currently, the best evidence suggests that in postmenopausal women, adding vitamin K to a vitamin D regimen (often also with calcium) has either a transient benefit (losing effect after a year) or no benefit for bone mineral density.[[3]](https://examine.com/faq/should-vitamin-k-be-supplemented-alongside-vitamin-d/#ref-3)[[4]](https://examine.com/faq/should-vitamin-k-be-supplemented-alongside-vitamin-d/#ref-4)[[5]](https://examine.com/faq/should-vitamin-k-be-supplemented-alongside-vitamin-d/#ref-5)[[6]](https://examine.com/faq/should-vitamin-k-be-supplemented-alongside-vitamin-d/#ref-6) Although some other studies have reported a benefit,[[7]](https://examine.com/faq/should-vitamin-k-be-supplemented-alongside-vitamin-d/#ref-7)[[8]](https://examine.com/faq/should-vitamin-k-be-supplemented-alongside-vitamin-d/#ref-8) high dropout rates and failure to control for multiple comparisons could have introduced bias into their findings.

“How To Increase Your Brain Power”
It's important to understand that when it comes to Vitamin D, none of the strategies I'm about to give you will hold a candle to daily sunlight exposure combined with adequate fat intake. But to get the memory-enhancement effect of increased Vitamin D (especially if you live in a northern climate or get limited sun exposure) include a few teaspoons of cod liver oil frequently in your diet, eat beef and butter, have calf’s liver now and then, and take approximately 2000-4000 daily international units (IU) of Vitamin D, preferably from a highly absorbable liquid source, such as a spray or an oil. When it comes to Vitamin D, there can be a law of diminishing returns, so I highly recommend you pair Vitamin D testing with your intake, and keep your levels between 40 and 80 ng/ml. Finally, if you're a vegetarian or vegan or eating inadequate amounts of fat, do not just take a bunch of D, because it can be toxic unless you pair it with A and K. ——————————————– 2) Vitamin K2  Your brain contains one of the highest concentrations of vitamin K2 in your entire body, and it is in this area of your body that Vitamin K2 prevents free radical damage to neurons and contributes to the production of the protective “myelin” sheets around your brain cells. In this book, I have already discussed Vitamin K2 in Chapter 14 as a very important supplement for vegans and vegetarians, Vitamin K2 is a relatively new darling on the supplement front, and many folks are rushing out to buy and use it for it’s bone building, brain building, and other remarkable benefits (2). But the fact is, unless you are vegan or vegetarian, or you have a serious deficiency or disease that requires K2 intake, you’re better off getting your K2 from natural sources such as grass-fed beef, fermented dairy products (like kefir) and natto (a fermented soybean derivative).Go back and read Chapter 14 if you want to learn more about K2 supplements and dosage. ——————————————– 3) Fatty Acids
