Verywell Health / Marcus Millan
From blood clotting to bone health to heart disease prevention, Vitamin K playsmany important roles in our body. You can find this important nutrient in leafy greens, other fruits and vegetables, some animal foods, and even cheese.Plus, your gut bacteria also produce some vitamin K in the large intestine. While a deficiency is rare, certain groups, like pregnant people, those whoeat a limited diet,have hadbariatric surgery,or havemalabsorptive disorders,may need an extra boost.
Experts are studying Vitamin K’s role in boosting bone density and heart health, though more research is needed. But we do know that Vitamin K works synergistically with vitamin D and calcium, so reallyanyone can benefit from this vitamin, according toAyla Barmmer, MS, RD, founder of FullWell.
We interviewed registered dietitians who are well-versed in vitamin K supplements and considered the form, dose, any independent or in-house purity and potency testing, and price to get our top recommended vitamin K supplements.

We recommend theLife Extension Super Kfor its broad spectrum coverage, quality in-house testing, and budget-friendly price point.Super K contains a blend of K1, and two types of K2 — MK-4 and MK-7—giving you everything you might need from a vitamin K supplement. The softgel also contains olive oil which may support the absorption of this fat-soluble vitamin. With 2,600 micrograms of vitamin K, the dose issignificantly higher than the AIof 90 to 120 micrograms, but there areno known risks of higher doses of vitamin K, and absorption rates may be as low as 30 to 40 percent for vitamin K supplements.
Super K isgluten-free and non-GMO, though it contains beeswax, so it isnot suitable for a vegan diet. Of note, it contains a small amount of vitamin C, which is safe for most people. However, always check with your healthcare provider to ensure it doesn’t interact with any medications you are taking.

To get our top picks for Vitamin K supplements, our team reviews the latest research on vitamin K supplements, absorption, dosing, and who can best benefit from taking a supplement. We interview experts to get their recommendations on specific products and input on taking supplements. You can read more about ourdietary supplement methodology here.
It is essential to carefully read a supplement’s ingredient list and nutrition facts panel to determine which ingredients are included and how much of each ingredient is included relative to its recommended daily value. Please bring the supplement label to a healthcare provider to review the different ingredients contained in the supplement and any potential interactions between these ingredients and other supplements and medications you are taking.
The main interactionconcern with vitamin K is with blood thinner medications. If you take medications, always consult with a healthcare professional before starting a vitamin K supplement.
Emerging research suggests thatvitamin D and K have a synergistic relationship in supporting bone and heart health, and there may be benefits to taking the two together.However, it’s important to evaluate your own needs with your healthcare provider.Not everyone needs a vitamin D supplement, and there are potential downsides to high amounts of vitamin D if you don’t need it. It’s recommended you have your vitamin D levels checked before starting a supplement.
If you’re getting adequate vitamin K through diet and do need a vitamin D supplement, there may still be a benefit to taking one with K, though more research is needed.Always check with your healthcare provider before starting a new supplement regimen.
The Adequate Intake of vitamin K is 90 micrograms for women (including those who are pregnant and breastfeeding) and 120 micrograms for men.However, some studies suggest that the amount needed to gain the potential bone health benefits may be higher—particularly in the form of MK-4. More research is needed to determine the best dose for each health outcome.
If you’re relying on a supplement to meet your daily vitamin K needs, it is important to take it daily. In addition, studies looking at the benefits of vitamin K supplements on health outcomes typically use daily supplementation.
There is no established tolerable upper intake level (UL) for vitamin K as there are no known adverse outcomes from taking high levels of vitamin K.However, more is not necessarily better, so work with your healthcare provider to determine the right amount for you.
We interviewed the following experts to get their take on the best forms of vitamin K, who can benefit from vitamin K supplements, and who can most benefit from them.
