Vitamin D3: The Sunshine Vitamin

Vitamin D3 (cholecalciferol) is the form of vitamin D produced by the skin in response to sunlight. It plays a crucial role in calcium absorption, immune function, and bone health.

Vitamin K2: The Activator

Vitamin K2 (menaquinone) helps direct calcium to the bones and teeth where it is needed, rather than allowing it to accumulate in soft tissues.

Why Take Them Together?

Vitamin D3 and K2 work synergistically. D3 increases calcium absorption, while K2 ensures that calcium is properly utilised. Together, they support:

  • **Bone health** — Stronger bones and teeth
  • **Heart health** — Helps maintain arterial flexibility
  • **Immune function** — Supports a healthy immune response
