Are Mushrooms High In Vitamin K? Straight Facts

If you type “are mushrooms high in vitamin k?” into a search bar, you probably care about vitamin K limits or a prescription blood thinner. The short answer is that most mushrooms sit on the low end of the vitamin K scale, especially when you compare them with leafy greens or fermented soy foods.

Raw white button mushrooms, the kind sold in most supermarkets, show almost no vitamin K on standard nutrient labels per 100 grams. By comparison, a similar amount of kale or spinach can push you well past an entire day’s suggested vitamin K intake. That gap matters if your doctor has asked you to steady your intake instead of avoid the nutrient completely.

Food	Typical Serving	Vitamin K (mcg)
White Button Mushrooms, Raw	1 cup sliced (70 g)	0
Cremini Mushrooms, Raw	1 cup sliced (72 g)	1
Shiitake Mushrooms, Cooked	1/2 cup (75 g)	1–2
Enoki Mushrooms, Raw	1 cup (65 g)	1–2
Spinach, Raw	1 cup (30 g)	145
Kale, Raw	1 cup chopped (67 g)	80
Broccoli, Cooked	1 cup (156 g)	220
Natto (Fermented Soybeans)	3 oz (85 g)	850

The table shows how mild mushroom vitamin K content looks beside classic high vitamin K foods. Even “higher” mushroom choices, like shiitake or enoki, land in the single digits per usual serving. Leafy greens and natto sit dozens or even hundreds of micrograms higher.

That contrast explains why diet sheets for warfarin and other vitamin K sensitive medicines talk far more about salad greens than about mushrooms. For many people following those plans, mushrooms count as low vitamin K vegetables that fit easily into meals once overall intake stays consistent from day to day.

How Vitamin K Works In Your Body

Vitamin K comes in two main forms in food: vitamin K1 from plants, especially leafy greens, and vitamin K2 from animal foods and fermented products. Both forms help your body handle blood clotting. They also contribute to bone health and other processes tied to calcium handling.

Health agencies set suggested daily intakes for vitamin K in the neighborhood of 90 micrograms per day for adult women and 120 micrograms per day for adult men. One clear summary comes from the National Institutes of Health vitamin K fact sheet. That sheet also lists food sources, medication interactions, and signs of low intake in clear, plain language for everyday readers everywhere.

People taking certain blood thinning medicines sit in a special group. These drugs work by blocking vitamin K steps in the clotting chain. Big swings in vitamin K from food can interfere with dose settings, which is why clinics often hand out lists of high vitamin K foods to eat in steady amounts instead of strict “never eat” lists.

Vitamin K And Blood Clotting

Several clotting factors in your blood need vitamin K to turn on. Without enough, cuts bleed longer and bruises show up more easily. On the flipside, if a person has a clotting disorder or certain heart rhythm issues, a doctor may prescribe a medication that slows vitamin K’s action to keep clots from forming in the wrong place.

People on these medicines do not usually need to avoid vitamin K completely. Instead, they try to keep day to day intake steady so test results remain predictable. In that setting, learning whether mushrooms count as high or low vitamin K helps with planning normal meals.

Vitamin K, Bones, And Other Roles

Vitamin K helps proteins in bone tissue handle calcium correctly. Research also looks at links between vitamin K intake and heart health, and findings still evolve. Because vitamin K is fat soluble, your body can store some of it, so daily intake does not need to land on one exact number each day.

Since mushrooms barely move your vitamin K total, they matter more for other nutrients. They bring in B vitamins, potassium, fiber, and, in some cases, vitamin D when exposed to ultraviolet light, all while keeping calories low.

Mushrooms And Vitamin K Content By Type

Not every mushroom in the produce aisle has identical vitamin K numbers, yet the pattern stays similar. Across common varieties, vitamin K contributions stay low, especially compared with greens.

Common Store Mushrooms

White button mushrooms headline the group. Lab data from nutrient databases that pull from the USDA FoodData Central system show zero micrograms of vitamin K per 100 grams for this variety. That means even a large serving adds almost nothing to your vitamin K tally.

Cremini and portobello mushrooms share the same species as white buttons. They come from the same plant at different maturity levels, so nutrient profiles look alike. Vitamin K numbers remain at zero or close to it in most nutrient tables, while flavor and texture shift as the cap darkens and opens.

Specialty Mushrooms

Shiitake, enoki, oyster, and similar mushrooms bring deeper flavor and a bit more vitamin K, yet still stay in the low range. Some databases list small amounts of vitamin K1 per 100 grams, often in the low single digits for usual cooked portions.

That means a stir fry packed with shiitake still owes most of its vitamin K to the greens or herbs tossed in with them. The mushrooms in the pan bring more interest, umami taste, and other nutrients but not much vitamin K.

Using Mushrooms On A Low Vitamin K Eating Plan

When a clinic tells a patient to follow a low, steady vitamin K pattern, fear about the produce aisle can creep in fast. Salad bars suddenly look tricky. In that moment mushrooms can feel like safe ground, since they add texture, flavor, and bulk without pushing vitamin K higher.

The main message from many anticoagulation clinics is consistency. If your dose was set while you were eating a serving of greens daily, stopping those greens can shift test results just as much as loading up on extra. In contrast, swapping one kind of mushroom for another hardly changes vitamin K at all, so recipes built around mushrooms tend to be easy to keep stable.

Meal Idea	Main Ingredients	Approx. Vitamin K (mcg)
Mushroom And Egg Breakfast Scramble	Eggs, white button mushrooms, onions, bell pepper	Low (mostly from vegetables)
Creamy Mushroom Pasta	Portobello mushrooms, garlic, cream, pasta	Low
Mushroom And Chicken Skillet	Chicken breast, cremini mushrooms, herbs	Low
Mushroom Soup With Crusty Bread	Mixed mushrooms, broth, onions, carrots	Low
Stir Fry With Mushrooms And Limited Greens	Shiitake mushrooms, small handful of cabbage, tofu	Moderate (from cabbage)
Salad With Mushrooms And Measured Spinach	Mushrooms, measured spinach, cucumber, olive oil	Higher (from spinach)

This sample list shows how mushrooms fit into meals that keep vitamin K predictable. The last two rows bring more vitamin K into the picture through cabbage or spinach, yet even then the mushrooms in those bowls still add almost none.

If you live with a medical condition that calls for steady vitamin K intake, always work with your prescribing clinician or clinic nurse. Share your usual portion sizes and ask how your own plan handles greens, fermented foods, and mushroom dishes.

Who Needs To Watch Mushroom Vitamin K Intake

For most healthy adults, mushrooms can show up on plates without much thought about vitamin K. They rarely change daily totals in a meaningful way, so the focus can stay on overall meal balance, enjoyment, and variety.

The people who care most about mushroom vitamin K usually fall into three groups. One group takes prescription blood thinners that interact with vitamin K. Another lives with past clotting events and tracks vitamin K closely. A third group reads about bone health nutrients and wonders whether loading up on mushroom dishes will raise vitamin K intake.

In each of these groups, mushrooms count as low vitamin K foods in almost all practical scenarios. Any effect on vitamin K intake comes mainly from the ingredients served alongside them. A spinach salad with mushrooms, as one example, lands in the high vitamin K category because of the greens, not because of the mushrooms sprinkled on top.

If you need individual advice, bring a short food diary to your health care team. Ask about the vitamin K content of your favorite meals, and check whether local lab printouts or clinic handouts list mushrooms in the low vitamin K column.

Bottom Line On Mushroom Vitamin K

Mushrooms deliver flavor, texture, and nutrients without adding much vitamin K. Raw white buttons show almost zero vitamin K on nutrient lists, and common varieties such as cremini, portobello, shiitake, and enoki stay low as well.

If you live with a condition that calls for steady vitamin K, mushrooms usually fit comfortably into that pattern. They let you build hearty omelets, stews, and pasta dishes while saving your vitamin K “budget” for measured portions of greens or other higher vitamin K foods.

So when you ask “are mushrooms high in vitamin k?”, the most accurate reply is simple: mushrooms are generally low vitamin K foods, and the real vitamin K decisions in your meals sit with the leafy greens and fermented products you choose to pair with them.
