When I first switched to a vegan lifestyle I worried about missing out on some essential nutrients. Vitamin K was one of those that caught my attention since it plays such a big role in keeping bones strong and helping blood clot properly. I quickly realized though that there are plenty of plant-based options out there.
Finding vegan sources of vitamin K isn’t as tricky as it seems. With a little know-how I discovered how easy it is to get enough of this important vitamin from foods I already love. Let me share what I’ve learned so you can feel confident about meeting your vitamin K needs on a vegan diet.
Understanding Vitamin K and Its Importance
Vitamin K supports blood clotting and bone strength, which I always stress in my vegan cooking classes. Two main types exist: K1 (phylloquinone) from leafy greens like kale and spinach, and K2 (menaquinone) from fermented foods and some animal products. My focus stays on maximizing K1-rich plants in recipes since these are core to a vegan kitchen.
Deficiency in vitamin K links to increased bleeding risk and weakened bones, with the National Institutes of Health confirming that most adults need 90–120 micrograms daily. When I teach vegan meal planning, I highlight specific greens, herbs, and vegetables rich in vitamin K. Eating a variety of these daily supports strong bones and healthy blood, which I see reflected in my own health and energy.
Cooking method affects vitamin K content; light steaming preserves most K1 in greens, while boiling can reduce it. I usually sauté or steam greens lightly to keep flavors vibrant and the vitamin K content as high as possible. Pairing greens with healthy fats like olive oil boosts absorption, a step I always show in my recipes for both nutrition and taste.
Types of Vitamin K
Vitamin K plays key roles in my plant-based kitchen, especially when it comes to supporting blood clotting and bone strength. I always focus on the two types of vitamin K when planning vegan meals.
Vitamin K1 vs Vitamin K2
Vitamin K1, or phylloquinone, comes mostly from leafy green vegetables, herbs, and some cruciferous veggies. In my vegan recipes, I use kale, Swiss chard, parsley, spinach, and broccoli to pack in plenty of K1. According to the National Institutes of Health, K1 is the main form of vitamin K in most diets.
Vitamin K2, or menaquinone, usually comes from fermented foods and some animal products. Vegans get K2 by adding plant-based fermented foods like natto (fermented soybeans). Other vegan-friendly sources include miso, sauerkraut, and tempeh. Most of my recipes rely on K1-rich plants, so I sometimes include these fermented dishes for variety.
Phylloquinone (K1) absorbs best when paired with healthy fats. I often drizzle olive oil or toss avocado into salads to boost the vitamin K my recipes provide.
Top Vegan Sources of Vitamin K
My kitchen thrives on simple, flavorful vegan foods that naturally deliver vitamin K. Below, I’ve gathered the plant-based ingredients I reach for most when creating recipes that boost both nutrition and taste.
Leafy Green Vegetables
Leafy green vegetables anchor my vitamin K meal planning. I rely on kale, spinach, collard greens, Swiss chard, and turnip greens. Sautéing chopped kale with olive oil or blending spinach into green smoothies joins vitamin K richness with flavor. Daily servings of 1 cup cooked spinach or kale provide more than 700 mcg of vitamin K1, according to the USDA FoodData Central.
Cruciferous Vegetables
Cruciferous vegetables like broccoli, Brussels sprouts, and cabbage also top my list. Steamed broccoli works great tossed with tahini or lemon, while roasted Brussels sprouts add depth to any grain bowl. One cup of cooked broccoli offers about 220 mcg of vitamin K1. Including these crucifers in stir-fries and salads ensures steady vitamin K intake.
Herbs and Spices
Fresh herbs such as parsley, cilantro, basil, and chives contribute bursts of flavor along with vitamin K. I sprinkle chopped parsley over pasta, add cilantro to tacos, and stir basil into soups. One-fourth cup of fresh parsley delivers close to 250 mcg of vitamin K1. Dried herbs also help, but I use fresh whenever possible for maximum vitamin K content.
Plant-Based Oils
Plant-based oils promote vitamin K absorption and double as healthy flavor carriers in my recipes. I drizzle extra virgin olive oil over greens or use avocado oil for roasting. Both oils increase the uptake of fat-soluble vitamins. Combining steamed greens with a teaspoon of olive oil improves absorption while enhancing taste and mouthfeel.
Other Vegan Foods Rich in Vitamin K
Other vegan foods contribute smaller but valuable amounts of vitamin K. Avocado, natto, prunes, kiwi, and fermented vegetables like sauerkraut and kimchi make regular appearances in my kitchen. Natto stands out with up to 1100 mcg vitamin K2 per 100 grams (NIH nutrient database), though its flavor profile suits only certain dishes. Kimchi and sauerkraut work as tangy toppings for bowls and salads, balancing flavor and nutrition.

Pairing vitamin K-rich foods with healthy fats increases absorption. I always drizzle olive oil on sautéed kale or add sliced avocado to spinach salads. These fats help my body use the phylloquinone from greens like Swiss chard, collard greens, and parsley.
Chopping or lightly steaming greens enhances vitamin K bioavailability. I chop kale for massaged salads or steam broccoli for grain bowls, making the nutrients more accessible. Raw preparations like fresh herb pestos and green smoothies also preserve vitamin K content.
Cooking methods matter. I avoid deep-frying or boiling greens for long periods, since those high-heat methods reduce vitamin K content. Light sautéing, steaming, roasting, and raw preparations preserve more of the vitamin in foods like Brussels sprouts and broccoli rabe.
Fermented foods provide plant-based vitamin K2. When I want more variety, I mix in natto or tempeh with brown rice, or top grain bowls with kimchi or sauerkraut. These meals add different forms of vitamin K and boost gut health.
Distributing vitamin K intake throughout the day supports consistent absorption. I add chopped chard to breakfast tofu scrambles, toss parsley into lunch wraps, and blend spinach into smoothies. Regular intake pairs well with an overall healthy vegan diet.
Being mindful of interactions helps too. Large amounts of vitamin E or certain blood-thinning medications can interfere with vitamin K utilization according to the National Institutes of Health. I always check with a dietitian or doctor if I or my students have concerns about medication or supplements.
Pairing, preparing, and varying plant-based foods ensures steady vitamin K absorption in my kitchen.
Potential Challenges and Considerations for Vegans
Absorbing vitamin K efficiently can challenge some vegans since phylloquinone (K1), the form in most plants, doesn’t absorb as well as the menaquinones (K2) found in animal products. My experience in both restaurants and home kitchens shows that pairing leafy greens with healthy fats like extra-virgin olive oil or avocado boosts the body’s ability to use vitamin K from a salad or sauté.
Meeting K2 needs with plant foods takes planning since few vegan items, like natto and tempeh, supply noticeable amounts. I rotate in fermented plant foods often, but I remind students who dislike these flavors to consult a provider about supplementation or seek out well-fortified foods.
Cooking methods may cause significant loss of vitamin K. I always use lighter techniques—quick steaming, sautéing, or raw preparations—since deep boiling or microwaving can lower vitamin K1 by up to 50% (USDA FoodData Central, 2023). Chopping greens before serving can also help improve phylloquinone bioavailability.
Medication interactions deserve careful attention. Individuals taking anticoagulants like warfarin need to keep vitamin K consumption steady every day, so I advise them to track intake closely with a dietitian’s guidance if making big recipe changes.
Digestive conditions such as celiac or Crohn’s disease may also affect vitamin K absorption. Several of my students who’ve experienced these conditions work with nutrition specialists to ensure their plant-based meals truly cover all bases.
I plan my meals so vitamin K comes from a wide variety of sources and gets spread throughout the day—this keeps both my nutrition and flavors balanced.
Conclusion
Exploring vegan sources of vitamin K has really opened up my kitchen to new flavors and creative meals. I love knowing that with a little planning and the right ingredients I can meet my needs while enjoying a colorful plant-based diet.
If you’re navigating your own vegan journey don’t stress about vitamin K. A few mindful choices and some tasty recipes can make it easy to get what your body needs—without missing out on great food.
