Vitamin K2 Guide | Benefits, Dosage & Best Sources for Bone Health

Overview

Vitamin K2 is essential for bone health, helping direct calcium into bones instead of arteries, reducing the risk of osteoporosis and heart disease. It works alongside vitamin D3, calcium, and magnesium to improve bone density and strength.

According to the National Osteoporosis Foundation, vitamin K2 plays a vital role in bone mineralization and preventing fractures.

Why Vitamin K2 is Essential for Bone Health

🦴 Directs Calcium to Bones

• Activates osteocalcin, a protein that binds calcium to bones.
• Prevents calcium from depositing in arteries.

💪 Strengthens Bone Density

• Works with vitamin D3 and magnesium to increase bone mineralization.
• Essential for preventing fractures in seniors.

🛡 Prevents Osteoporosis & Arterial Calcification

• Without K2, calcium may build up in soft tissues instead of bones.
• K2 reduces the risk of arterial stiffness and cardiovascular disease.

❤️ Supports Heart Health

• Lowers calcification in arteries, keeping the cardiovascular system healthy.
• Reduces risk of heart disease by preventing calcium buildup.

Best Sources of Vitamin K2 for Bone Health

🌱 Food Sources

1. Natto (Fermented Soybeans) (Richest source of K2)
2. Grass-Fed Dairy Products (Cheese, Butter, Yogurt)
3. Egg Yolks (Higher in pasture-raised eggs)
