Vitamin K is a fat-soluble nutrient that plays a critical role in several bodily functions, most notably blood clotting and bone metabolism. While leafy greens like kale and spinach are the most concentrated sources, relying solely on them can feel restrictive for some. Fortunately, certain fruits can provide a welcome boost of this essential vitamin.
What Fruit Gives You Vitamin K? A Look at the Top Contenders
While fruits generally contain less vitamin K than leafy greens, some stand out as significant sources. Incorporating these into your diet is an excellent way to diversify your nutrient intake.
Nutrient-Packed Berries: Blueberries and Blackberries
Berries are among the best fruit sources of vitamin K. Blueberries and blackberries are particularly notable for their content and antioxidant properties. Just one cup of raw blueberries can provide a good percentage of the Daily Value (DV). Similarly, blackberries offer a comparable amount, making both excellent additions to smoothies, oatmeal, or a snack. In addition to vitamin K, these berries are also packed with fiber and vitamin C, supporting overall health.
The Kiwi: A Green Powerhouse
Often praised for its high vitamin C content, the humble kiwi is also an impressive source of vitamin K. A single medium-sized kiwi can provide a significant boost to your daily needs, with a 100g serving offering around 40 µg, covering a solid portion of the DV. This makes it one of the most vitamin K-dense fresh fruits available.
Dried Fruits: Prunes and Dried Figs
When fruits are dried, their nutrient content often becomes more concentrated, including vitamin K. Prunes (dried plums) are a powerful example. A small serving of five prunes can offer a solid amount of vitamin K. Research indicates that consuming the whole fruit is much more beneficial than juice, as prune juice contains considerably less vitamin K. Dried figs are another option, also providing a decent amount per serving.
Other Notable Fruit and Plant-Based Sources
Other fruits and plant-based foods also contribute to your vitamin K intake, though in smaller amounts. These include:
- Avocado: This creamy fruit provides a moderate amount of vitamin K, with half a medium avocado offering a good percentage of the DV.
- Grapes: Red or green grapes contain a helpful amount of vitamin K per serving.
- Pomegranate: Both the fruit and its juice contain vitamin K and potent antioxidants.
- Pumpkin: Canned pumpkin is a convenient source, with a half-cup serving providing a decent amount.
