The Sunshine Vitamin: Why D3 is So Important

Vitamin D3 (cholecalciferol) is, strictly speaking, not a vitamin but a hormone that our body can produce itself with the help of sunlight. In Germany, however, up to 60% of the population do not reach the recommended vitamin D levels – especially in the winter months from October to March.

Vitamin D3 fulfills numerous vital functions:

  • Bone health: Promotes calcium absorption from the intestine
  • Immune system: Strengthens the body's defense against infections
  • Dental health: Supports the mineralization of tooth enamel
  • Muscle strength: Important for normal muscle function
  • Mood: Positively influences serotonin production

Vitamin K2: The Underestimated Partner

Vitamin K2 (menaquinone) is far less known than D3, but plays a crucial role in calcium metabolism. It ensures that calcium ends up where it belongs – in bones and teeth – and not in the blood vessels.

The most important functions of Vitamin K2:

  • Calcium conductor: Activates osteocalcin, which incorporates calcium into the bones
  • Vascular protection: Activates Matrix-GLA protein, which prevents calcification in arteries
  • Dental health: Supports the remineralization of tooth enamel
  • Bone density: Reduces the risk of osteoporosis

Why Take D3 and K2 Together?

The combination of Vitamin D3 and K2 is scientifically supported. The reason lies in calcium metabolism:

  1. Vitamin D3 significantly increases calcium absorption from food.
  2. The additional calcium must be transported to the right places.
  3. Vitamin K2 activates the proteins that incorporate calcium into bones and teeth.
  4. Without K2, the calcium mobilized by D3 can be deposited in the blood vessels.

The Right Dosage

Vitamin Daily Recommendation In Case of Deficiency
Vitamin D3 1,000–2,000 IU Up to 4,000 IU (medical consultation)
Vitamin K2 (MK-7) 75–200 µg 200 µg

Important: The MK-7 (menaquinone-7) form has a significantly longer half-life than MK-4 and works more sustainably.

D3 + K2 and Dental Health

A particularly exciting area is the influence on dental health:

  • Tooth enamel: D3 and K2 together promote remineralization
  • Gums: D3 strengthens the immune defense in the oral cavity
  • Jawbone: Both vitamins support bone density
  • Oral flora: Vitamin D3 positively influences oral bacteria

That's why Delvina Oral Flora Lozenges also contain Vitamin D3.

Natural Sources vs. Supplements

Vitamin D3 in Foods

Only a few foods contain significant amounts: fatty fish, egg yolk, and cod liver oil. Sufficient supply through diet alone is hardly possible.

Vitamin K2 in Foods

Good sources include fermented foods such as natto, certain cheeses (Gouda, Brie), and sauerkraut.
