Best Foods Rich in Vitamin K: Daily Choices for Optimal Health

What's the Deal with Vitamin K?

Alright, let's start with the basics. Vitamin K isn't just one thing – it's actually a group of vitamins that come in two main flavors: K1 and K2.

• Vitamin K1 (phylloquinone): This is the most common form, and you'll find it hanging out in plant foods, especially those leafy greens your mom always told you to eat.
• Vitamin K2 (menaquinone): This one's a bit trickier to find. It's in some animal products and fermented foods.

Why Your Body Loves Vitamin K

• It's your body's personal EMT: Vitamin K helps your blood clot when you get a cut. Without it, you'd be like a leaky faucet!
• Bone builder extraordinaire: It teams up with calcium to keep your bones strong and sturdy.
• Heart helper: Some studies suggest it might help keep your ticker in top shape.

How Much Do You Need?

• 90 micrograms for women
• 120 micrograms for men

Don't stress too much about the exact numbers – just focus on including vitamin K-rich foods in your diet regularly.

Dairy Delights

• Soft Cheeses: Brie and Camembert contain around 17 mcg per ounce (14% DV).
• Full-fat Milk: While not super high, it does contribute some K2 to your diet.

Dr. Aaron Erez says,

“As a Certified Functional Medicine practitioner, I know the consequences of Vitamin K deficiency. Without enough K1 and K2, patients can suffer impaired blood clotting, bone fragility, and calcium buildup in arteries. Maintaining adequate Vitamin K promotes bone and heart health, and may help manage chronic inflammatory diseases. My practice focuses on prevenring and managing chronic disease through nutrition and lifestyle. For K2, I recommend eating natto, hard cheeses, egg yolks and grass-fed meat. K1 is found in leafy greens like kale and spinach. For some patients, K2 supplements provide higher doses that diet alone can't achieve. Vitamin K shows promise for supporting long term health.”

Making Vitamin K a Part of Your Life

Now that you know where to find vitamin K, let's talk about how to get more of it into your diet:

• Green up your plate: Try to incorporate a serving of leafy greens or other vitamin K vegetables into your diet at least once daily.
• Herb it up: Use fresh herbs in your cooking for a flavor and nutrient boost.
• Snack smart: Keep kiwis, avocados, or a handful of prunes on hand for quick, vitamin K-rich snacks.
• Don't fear fat: A little healthy fat helps your body absorb vitamin K better, so don't shy away from a drizzle of olive oil on your salad.
• Experiment with fermented foods: Try incorporating natto or other fermented foods into your diet for a K2 boost.

When Vitamin K Goes MIA: Deficiency Talk

While vitamin K deficiency is rare in adults, it can happen. Here's what to watch out for:

• Excessive bleeding or bruising
• Weak bones
• Slow wound healing

You might be at risk if you:

• Have certain digestive disorders
• Are on long-term antibiotics
• Take blood thinners

If you're concerned, chat with your doctor. They're the best person to advise you on your specific needs.

Special K Considerations

• Newborns: Babies often get a vitamin K shot at birth to prevent bleeding problems.
• Blood Thinners: If you're on blood thinners like warfarin, keep your vitamin K intake consistent and talk to your doctor about any dietary changes.
• Supplements vs. Food: While supplements are available, getting your vitamins from food is usually the way to go unless your doctor says otherwise.
