Why Vitamin K Deserves Your Attention

Vitamin K isn’t just a one-trick pony. This powerhouse nutrient works behind the scenes to keep you thriving:

Blood Clotting: It activates proteins that stop bleeding when you’re injured.
Bone Strength: It teams up with calcium to build and maintain strong bones.
Heart Health: Early studies, like those from the National Institutes of Health, hint it may prevent calcium buildup in arteries.

There are two key players:

Vitamin K1 (phylloquinone): Abundant in leafy greens.
Vitamin K2 (menaquinone): Found in fermented foods and some animal products.

K1 keeps your blood in check, while K2 shines for bones and heart health. Ready to meet the foods that deliver them?

Bioavailability Boost: Natto’s K2 is absorbed better than K1 from greens, making it a standout choice.

Heads-Up: On blood thinners like warfarin? Vitamin K can interfere—chat with your doctor first, per Mayo Clinic advice.

Why These Foods Matter More Than You Think

Vitamin K isn’t just about meeting a daily quota—it’s about balance. Too often, we lean on supplements when whole foods like these offer a richer, more natural package. I’ve learned that mixing K1-rich greens with K2 sources like natto keeps me feeling my best. Plus, there’s something satisfying about eating foods with a story—natto’s funky history or kale’s rise to fame.
