Grapes contain some vitamin K, but one cup has 13.4 mcg, so they’re not a high source for most diets.
If you’re watching vitamin K, grapes can feel like a question mark. They’re small, easy to snack on, and show up in fruit bowls, lunchboxes, and party trays. The catch is that vitamin K isn’t one of the nutrients people track every day, until they need to. It’s a small detail that can shift plans. If you’ve typed are grapes high in vitamin k? into a search bar, you’re in the right spot.
This guide gives you the numbers, then shows how serving size, grape type, and your own situation change the answer. You’ll walk away knowing when grapes are a simple “go for it” and when it’s smarter to measure your portion.
Are Grapes High In Vitamin K? Numbers By Serving
On the Nutrition Facts label, vitamin K uses a Daily Value of 120 mcg. You can see that value on the FDA Daily Value list. With that yardstick, a typical cup of raw grapes lands in the low-to-mid range.
The table below uses vitamin K (phylloquinone) values from the USDA’s vitamin K list, with percent Daily Value calculated from 120 mcg. (The USDA list is here: USDA Vitamin K (phylloquinone) table.)
| Food And Serving | Vitamin K (mcg) | Percent Daily Value |
|---|---|---|
| Spinach, raw, 1 cup | 144.9 | 121% |
| Broccoli raab, raw, 1 cup chopped | 89.6 | 75% |
| Kale, raw, 1 cup | 81.8 | 68% |
| Kiwifruit, green, raw, 1 cup sliced | 72.5 | 60% |
| Blueberries, frozen, sweetened, 1 cup thawed | 40.7 | 34% |
| Grapes, canned, Thompson seedless, water pack, 1 cup | 24.0 | 20% |
| Carrots, raw, 1 cup chopped | 16.9 | 14% |
| Grapes, American type (slip skin), raw, 1 cup | 13.4 | 11% |
So, are grapes “high” in vitamin K? For most people, no. A cup of raw grapes gives 13.4 mcg, which is 11% of the Daily Value. You’d need large portions to get into the same territory as leafy greens.
Still, grapes aren’t at zero. If your day has other vitamin K foods—salads, broccoli, herbs, green smoothies—the grapes stack on top of that total. That’s why the same bowl of grapes can feel tiny in one diet and noticeable in another.
Vitamin K In Grapes With Color And Form
“Grapes” includes many kinds of fruit in one word: different varieties, different skins, different growing conditions, and different handling after harvest. Vitamin K sits in that mix too, so it helps to think in ranges instead of one magic number.
Fresh Grapes Versus Canned Grapes
The USDA list shows raw American-type grapes at 13.4 mcg per cup, while canned Thompson seedless grapes in water pack come in at 24 mcg per cup. That gap doesn’t mean canned is always higher across every brand or packing liquid. It does show that processing choices can shift the final count.
If you eat grapes from a can, check the serving size on the label and stick with it. A “cup” in a database is one thing, while the serving on your can may be smaller or larger.
Red, Green, Seeded, Seedless
Most grocery-store grapes are red or green, often seedless. Their vitamin K is still modest. The bigger swing usually comes from the amount you eat, not the color. If you free-pour grapes into a bowl, it’s easy to turn one cup into two without noticing.
Try this simple portion check: fill a measuring cup once, dump it into your bowl, then eyeball that amount. After you’ve done it a few times, your “one cup” guess gets a lot closer.
What Vitamin K Does And Why People Track It
Vitamin K is a fat-soluble vitamin that helps your body make proteins involved in blood clotting. It also plays a part in bone metabolism through proteins that need vitamin K to work as intended. In food, the main form is vitamin K1 (phylloquinone), which is common in plant foods.
When you see vitamin K on a label, it’s listed in micrograms (mcg). The percent Daily Value helps judge dose size fast. Vitamin K in fruit is mainly the K1 form. Vitamin K2 shows up more in fermented foods and certain animal foods, so grapes won’t be your main source there.
That biology is why the same nutrient shows up in two conversations: everyday nutrition and medication management. If you’ve never had a reason to track vitamin K, grapes probably never raised your eyebrow. Once you do track it, small amounts can matter because you’re paying attention.
When Grapes Matter For Vitamin K Tracking
For most eaters, grapes sit in the “nice-to-have” range: they add fiber, fluid, and a sweet bite with only a modest dose of vitamin K. There are a few cases where the details matter more.
If You Take Warfarin Or Another Vitamin K Antagonist
Warfarin works by interfering with vitamin K’s role in clotting. Big swings in vitamin K intake can make dosing harder to manage. In that setting, grapes are usually fine, yet consistency still matters. If you eat one cup of grapes every day, keep that pattern steady instead of bouncing between none and a large bowl.
If you’re changing your diet on purpose—more salads, less processed food, more fruit—tell the clinician who manages your anticoagulant plan. The goal is a steady pattern, not fear of one food.
If You’re Trying To Keep Vitamin K Low
Some people aim low because they’re new to anticoagulants and want fewer moving parts. Grapes can fit, since the per-cup number is modest. What trips people up is the “grape drift”: one cup becomes two, then three, because they’re easy to eat by the handful.
A practical trick: portion grapes into small containers right after you wash them. When the container is empty, you’re done. No guessing.
If You Use A Vitamin K Supplement
Some multivitamins include vitamin K, and standalone vitamin K supplements exist too. When supplements enter the picture, the vitamin K from food can feel smaller. Still, food plus supplements adds up. If you track numbers, count both.
Ways To Eat Grapes Without A Surprise Vitamin K Jump
Grapes work best when you treat them like a planned snack, not endless popcorn. Here are a few simple moves that keep your intake steady without turning eating into a math class.
- Pick a portion once. Use 1 cup, 1/2 cup, or 2 cups as your repeatable “unit,” then stick with it for a week.
- Pair them with protein or fat. Grapes with yogurt, cheese, nuts, or a boiled egg feel more filling, so you’re less likely to keep grazing.
- Keep greens and grapes separate. If you’re tracking vitamin K, a spinach salad plus a big bowl of grapes can stack quickly. Split them across meals.
- Freeze some. Frozen grapes slow you down. You eat them one at a time, not by the fistful.
None of this is meant to make grapes scary. It’s just the cleanest way to control the variable you can control: how much goes into your bowl.
Grape Serving Math That Matches Real Snacking
Once you know the per-cup value, you can scale it to your usual portion. The table below uses 13.4 mcg per cup for raw grapes and converts it into common serving sizes. Percent Daily Value uses the same 120 mcg label value.
| Grape Portion | Vitamin K (mcg) | Percent Daily Value |
|---|---|---|
| 1/2 cup raw grapes | 6.7 | 6% |
| 1 cup raw grapes | 13.4 | 11% |
| 1 1/2 cups raw grapes | 20.1 | 17% |
| 2 cups raw grapes | 26.8 | 22% |
| 3 cups raw grapes | 40.2 | 34% |
| 1 cup canned grapes, water pack | 24.0 | 20% |
| 2 cups canned grapes, water pack | 48.0 | 40% |
That last pair of rows is a good reality check: if your “fruit snack” is a big bowl of canned grapes, you can move from a modest dose to a bigger one fast.
Buying And Storing Grapes So Portions Stay Simple
Grapes are one of those foods that vanish because they’re ready the second you open the fridge. A little prep turns that into a win for consistency.
Wash, Dry, Then Portion
Rinse grapes, then dry them well. Wet grapes stick together, so it’s easy to scoop extra. Once they’re dry, portion them into small containers or bags in the size you plan to eat.
Keep A “Snack Bowl” And A “Cooking Bowl”
If you use grapes in salads, chicken salad, or yogurt bowls, set aside a container for cooking and a container for snacking. That way you don’t double-dip and lose track of your totals.
Checklist Before You Call Grapes High In Vitamin K
When someone asks, “are grapes high in vitamin k?” the best answer depends on context. Run through these quick checks:
- How big is your serving? One cup is modest. Two or three cups changes the story.
- What else is on your plate? If you already eat leafy greens that day, grapes add on top.
- Are you using a medication where vitamin K swings matter? Keep your pattern steady and flag big diet shifts to your prescriber.
- Are you comparing grapes to “high vitamin K foods”? Leafy greens and broccoli family foods sit far higher per serving.
For most diets, grapes are a low-stress fruit with a modest amount of vitamin K. If you’re tracking vitamin K closely, the move is simple: measure once, pick a repeatable portion, and keep your pattern steady.
If you still feel unsure after doing the serving math, bring your typical day of eating to your next appointment and ask for a quick review. A small tweak is often all it takes.
