Vitamin D3-K2

Vitamin D3 (cholecalciferol) and Vitamin K2 (menaquinone) are two fat-soluble vitamins that work synergistically to support bone, heart, and immune health. When taken together, they help ensure that calcium is properly absorbed and directed to the right places in the body.

Vitamin D3 (Cholecalciferol)

 Role

•  Helps the body absorb calcium and phosphorus.
• Crucial for maintaining strong bones and teeth.
• Supports immune system function, muscle strength, and mood regulation.

Primary Sources

• Sunlight exposure (UVB radiation)
• Fatty fish (salmon, mackerel)
• Egg yolks
• Fortified foods
• Supplements

Vitamin K2 (Menaquinone)

 Role 

• Regulates where calcium goes in the body.
• Activates proteins that move calcium into bones and keep it out of arteries.
• Supports cardiovascular health by preventing arterial stiffness.

Primary Sources

• Natto(fermented soybeans — the richest source)
• Hard and soft cheeses
• Grass-fed dairy
• Pastured egg yolks
• Fermented foods (sauerkraut, kefir)

Why D3 and K2 Work Better Together

1. Optimized Calcium Use

 D3 increases calcium absorption from the gut.
K2 directs that calcium into bones and teeth, preventing buildup in soft tissues.

2. Bone Health

• D3 helps maintain calcium levels.
• K2 activates osteocalcin, a protein that “locks” calcium into bones.

3. Heart and Artery Protection

• K2 activates matrix GLA protein, which removes calcium from arteries.
• This reduces the risk of calcification and supports healthy blood vessels.

4. Improved Overall Balance

• Taking D3 alone may raise calcium levels too much.
• K2 helps ensure calcium is used safely and effectively.
