Surprising Foods Richer in Vitamin K Than Kale

Kale gets a lot of love for being a nutritional powerhouse, and with good reason it’s rich in fiber, antioxidants, and especially vitamin K. But did you know there are several other foods that pack even more of this essential vitamin?

Vitamin K plays a key role in blood clotting and bone health, yet many people don’t realize just how easy it is to meet or exceed their daily needs often without even trying. While 1 cup of raw kale contains about 81.8 micrograms (mcg) of vitamin K and a ½ cup of cooked kale offers around 247 mcg, here are 10 other foods that contain even more.

1. Spinach

• Vitamin K: 890 mcg (cooked), 145 mcg (raw)

  Spinach is rich in vitamins A, C, and E, plus essential minerals like iron and magnesium. Whether it’s in a morning omelet, a lunchtime salad, or sautéed for dinner, this leafy green is one of the easiest ways to get a major vitamin K boost.

2. Turnip Greens

• Vitamin K: 530 mcg (cooked), 138 mcg (raw)

5. Beet Greens

Can You Get Too Much Vitamin K?

While vitamin K is fat-soluble, no known toxicity exists from consuming it through food, even in large amounts. However, vitamin K can interfere with certain medications, especially blood thinners like warfarin (Coumadin).

Talk to your healthcare provider before significantly increasing your intake if you take:

• Blood thinners – High vitamin K can reduce the medication's effectiveness.

• Antibiotics – Some can lower vitamin K levels by disrupting gut bacteria.

• Fat-blocking weight-loss drugs – These may reduce your body’s absorption of fat-soluble vitamins, including K.

The recommended daily intake for adults is around 90 mcg for women and 120 mcg for men, and many people meet this easily through diet alone.

In Summary

Kale is great but it's far from the only food rich in vitamin K. Leafy greens like spinach, chard, and mustard greens, plus fermented foods like natto, all pack a serious punch. By mixing and matching these nutrient-dense foods, you can support your bone health, circulation, and overall wellness with ease.
