How to Get More Vitamin K from Food

Introduction to Vitamin K

Vitamin K is a crucial nutrient known for its role in blood clotting and bone health. There are two main forms: Vitamin K1 (phylloquinone) found in plants and Vitamin K2 (menaquinones) synthesized by bacteria in the gut and found in animal products.

Importance of Vitamin K

Why is Vitamin K important for health?

Vitamin K plays a vital role in:

• Blood Clotting: Essential for the synthesis of clotting factors.
• Bone Health: Helps in bone mineralization and reducing fracture risk.
• Heart Health: May contribute to cardiovascular health by reducing arterial calcification.

Sources of Vitamin K

Natural Food Sources

• Vitamin K1 Sources: Leafy green vegetables (spinach, kale, broccoli), cruciferous vegetables (cabbage, Brussels sprouts), herbs (parsley, basil).
• Vitamin K2 Sources: Fermented foods (natto, cheese), animal liver, meat, eggs.

Recommended Daily Intake

The Adequate Intake (AI) for Vitamin K varies by age and gender:

• Adults: 90-120 micrograms/day for women and men, respectively.
• Higher AI during pregnancy and lactation.

Maximizing Your Vitamin K Intake

Tips for Increasing Vitamin K Consumption

• Include Leafy Greens: Incorporate spinach, kale, and Swiss chard into salads, smoothies, or cooked dishes.
• Add Cruciferous Vegetables: Enjoy broccoli, Brussels sprouts, and cabbage in stir-fries or roasted dishes.
• Choose Fermented Foods: Incorporate natto, a Japanese fermented soybean dish, or fermented cheeses into your diet.
• Include Animal Products: Consume eggs, liver, and meat from pasture-raised or grass-fed animals.
• Use Herbs: Flavor meals with parsley, basil, cilantro, or thyme to boost Vitamin K content.
