Vitamin K is a powerhouse in your body. It helps build strong bones. It helps regulate blood clotting. And it helps keep your blood pressure in check.

Most of us can get plenty of vitamin K through the foods we eat. This is a good thing, as at least some research suggests vitamin K supplements may not be very effective.

“Getting vitamins from your food is always better than relying on supplements,” says registered dietitian Julia Zumpano, RD, LD.

“Vitamin K is made from short-chain molecules, so it passes through your body quickly. That means that if you take a vitamin K supplement, it doesn’t spend much time in your body and doesn’t give you the full benefits you’d get from eating foods high in vitamin K.”

We talked with Zumpano about why vitamin K is important in your diet and the best foods to fill up on vitamin K.

What vitamin K does

Vitamin K is a category of vitamins. There are two variations: vitamin K1 and vitamin K2. Both do similar things for your body.

“Vitamin K1 has long been known for its benefits throughout your body,” Zumpano says. “But it’s now becoming clearer that vitamin K2 may be just as important in those processes.”

More research is being done to understand whether vitamin K1 or vitamin K2 is more effective or efficient in any particular role in your body. But it’s clear that K vitamins have several important benefits:

  1. Regulates blood clotting. Vitamin K can help keep you from bleeding out after an injury. And it helps keep your blood from getting too thick, which can lead to blood clots.
  2. Keeps your bones strong. Vitamin K works with calcium and vitamin D to build healthy bones. That means fewer fractures and a lower risk of osteoporosis.
  3. Prevents calcium buildup. Vitamin K clears away calcium deposits from your blood vessels. That means less calcification (hardening) in your arteries, and a reduced risk of high blood pressure, kidney disease and more.

Chart: Best foods for vitamin K

Vitamin K1 is mostly associated with plant-based foods. Vitamin K2 is more common in animal products, dairy and fermented foods.

So, while vitamin K1 foods tend to come with additional health benefits, like other vitamins and minerals, vitamin K2 foods aren’t always the healthiest choices.

The U.S. Department of Agriculture’s (USDA’s) Dietary Guidelines for Americans suggests these recommended daily allowances of vitamin K for adults 18 and older:

  • 90 micrograms for women and people assigned female at birth.
  • 120 micrograms for men and people assigned male at birth.
  • 75 to 90 micrograms for people who are pregnant or lactating.

The USDA doesn’t have specific recommendations for how much of your intake of vitamin K should come from vitamin K1 versus vitamin K2. The guidelines are based on a total amount of vitamin K from all sources.

Get the most out of your vitamin K foods

To help your body fully absorb vitamin K, Zumpano suggests eating a bit of fat along with vitamin K-rich foods.

“Vitamin K is a fat-soluble vitamin,” she explains. “It dissolves in fat to be stored in your body, rather than leaving it immediately as waste. So, eating a bit of healthy fat with or before eating foods rich with vitamin K will help your body reap the most benefits.”

Foods high in unsaturated fats are healthy choices to eat just before vitamin K-rich foods. Try pairing your vitamin K sources of healthy fats with:

For example, you could toss a spinach and kale salad (vitamin K) with olive oil dressing and avocado (fats). Or mix fresh blueberries (vitamin K) in your plain yogurt (fat). Or munch on a charcuterie board of dry roasted cashews (vitamin K) and olives (fat).

You get the idea.

And you don’t have to eat a lot of fat to get the vitamin-absorbing effects. Just a bit will do. The goal should be to fill up more on vitamin-rich foods than on fats, even if they’re healthier fats.

Pro tip: This same fat-plus-vitamins approach is best for other fat-soluble vitamins as well. That includes vitamin A, vitamin D and vitamin E.

Note: Some vitamins, like vitamin C and B vitamins, are water-soluble. They use water — not fat — to be absorbed by your body. Drink a glass of water when taking those vitamins or eating foods rich in them.

Can you have too much vitamin K?

If you take a blood thinning medication, such as warfarin (Coumadin®), vitamin K can raise your risk for blood clots. That doesn’t necessarily mean you need to avoid all vitamin K-rich foods. You just should be careful not to go overboard or to drastically increase your intake. And you certainly should not take a vitamin K supplement without talking with your healthcare provider.

For everyone else, a diet rich in vitamin K is healthy for your bones, blood and heart.

“Soy, leafy greens and fruits that are rich in vitamin K are good for so many of your body’s systems,” Zumpano emphasizes. “They’re foods that should be a staple in just most people’s heart-healthy diets.”
