Two nutrients. Distinct roles.

  • Vitamin D3

    Supports the absorption and use of calcium and phosphorus, contributes to the maintenance of bones and teeth, and plays a role in normal immune function.

  • Vitamin K2

    Contributes to the maintenance of bones through vitamin K-dependent proteins involved in bone metabolism.

Where their roles intersect

Vitamin D3 and vitamin K2 are distinct nutrients with different roles in the body. Vitamin D3 has broader physiological functions, while vitamin K2 contributes to the maintenance of bones. Their relationship becomes especially relevant in bone and calcium metabolism, where their functions intersect without being interchangeable.
