Do String Beans Have Vitamin K? | Quick Facts Guide

Do String Beans Have Vitamin K: Amounts, Benefits, And Tips

Yes. Green beans—also called string beans or snap beans—carry vitamin K in useful amounts. Per 100 grams, raw beans provide about 43 micrograms, and cooked beans sit near 46 micrograms. That’s roughly one third of the label Daily Value, so even a modest serving moves the needle.

Why it matters: vitamin K supports normal blood clotting and activates bone proteins that depend on this nutrient. You don’t need megadoses from pills to get there. A steady mix of vegetables, with string beans in the rotation, covers the goal without fuss.

Vitamin K In String Beans By Serving

Here’s a simple view of everyday portions. Values are rounded for meal planning.

Form	Serving	Vitamin K (mcg)
Raw string beans	100 g	~43
Cooked string beans	100 g	~46
Raw string beans	10 beans (~55 g)	~24

Two quick notes. First, cooking barely shifts vitamin K here; steaming or sautéing keeps numbers close to raw. Second, the 100-gram baseline matches many labels, so it’s easy to compare across foods.

How String Beans Fit Your Daily Vitamin K Needs

Dietary targets use two yardsticks. The Daily Value on labels is 120 micrograms, and the Adequate Intake is 120 micrograms for men and 90 micrograms for women (see the NIH overview of vitamin K for details in the health-professional fact sheet). A 100-gram serving of beans reaches about 36–38% of the label Daily Value and roughly half of the women’s Adequate Intake.

Now zoom out. Beans also bring fiber, which helps meals feel satisfying. If you’re building a plate for fullness and digestion, it helps to benchmark your recommended fiber intake while you plan portions.

Preparation Methods That Keep The Good Stuff

Steam For Tender, Bright Pods

Steam over simmering water for 5–7 minutes until crisp-tender. Drain well and toss with a teaspoon of olive oil, lemon zest, and a pinch of salt. That small bit of fat helps your gut absorb fat-soluble nutrients like vitamin K.

Sauté For Flavor Fast

Heat a skillet, add oil, then garlic. Toss in the beans and cook 4–6 minutes. Finish with lemon juice or a splash of vinegar to balance the richness. You’ll keep texture, color, and nearly the same vitamin K as raw.

Roast For Caramelized Edges

Spread on a sheet pan, drizzle oil, and roast at 425°F for 12–15 minutes. The dry heat concentrates flavor without slashing vitamin K. Add a tahini-yogurt drizzle or toasted sesame for a little extra flair.

What About Frozen Or Canned String Beans?

Frozen beans perform well because they’re blanched and chilled before packaging. That quick heat step doesn’t erase vitamin K. Canned beans are softer and saltier, but their vitamin K sits near cooked numbers. Rinse canned beans to lower sodium before reheating.

Pairing Ideas To Build A Vitamin K-Smart Plate

Simple Mains With Beans On The Side

• Pan-seared salmon with lemon and a heap of roasted beans.
• Grilled chicken, garlicky green beans, and whole-grain couscous.
• Tofu stir-fry with beans, bell peppers, and sesame.

Salads That Pull Their Weight

• Chilled bean salad with cherry tomatoes, feta, and a spoon of olive oil.
• Warm beans and arugula with balsamic and shaved parmesan.
• Three-bean toss: green beans, chickpeas, and kidney beans with herbs.

Vitamin K, Medications, And Consistency

If you take warfarin, the goal isn’t to avoid greens or string beans; it’s to keep intake steady. Work with your care team on a pattern that fits your dose and INR checks. Sudden swings—big plate one day, none the next—can nudge results off track. A steady, predictable intake of vitamin K foods helps dosing make sense.

How Much Vitamin K Should You Aim For Each Day?

Most adults hit the mark by eating a mix of vegetables. A plate that includes beans, leafy greens, and a bit of healthy fat gets you there reliably. The label Daily Value is 120 micrograms. If you’re counting, two modest servings of string beans plus another green vegetable usually covers it without needing a supplement.

Meeting Your Target: Practical Benchmarks

Use these rounded benchmarks to sketch meals without a calculator. Numbers assume cooked beans at ~46 micrograms per 100 grams.

Portion Of String Beans	Vitamin K (mcg)	% Of 120 mcg DV
50 g cooked	~23	~19%
100 g cooked	~46	~38%
150 g cooked	~69	~58%

Round out the plate with colorful vegetables, lean proteins, and whole grains. Drizzle a teaspoon or two of olive oil to help fat-soluble vitamins do their job.

Nutrition Profile Beyond Vitamin K

String beans are light on calories and bring fiber, vitamin C, carotenoids, and small amounts of minerals. That combo suits heart-conscious meals and weight-aware plans. Beans pair well with citrus, garlic, almonds, and fresh herbs, so you can keep the pattern interesting all week.

Storage And Prep That Save Time

Refrigerate unwashed beans in a breathable bag. Use within 4–5 days for snap and color. Trim ends just before cooking. If you meal-prep, blanch for two minutes, chill in ice water, dry well, and store for quick sautéing later.

Putting It All Together

Yes—string beans have vitamin K, and the amounts are meaningful. A 100-gram serving gives around 40–46 micrograms, which is about one third of the label Daily Value. Keep intake steady if you’re on warfarin. For most people, pairing beans with a little fat and a second green vegetable makes hitting the day’s number simple and repeatable.
