Vitamin D3 is basically a fat-soluble vitamin that helps support bone health and immune function.

This form is paired with vitamin K2 MK-7 to help calcium metabolism and boost absorption, helping the body use calcium more efficiently.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake and supports immune cells, aligning with EFSA and NHS guidance on everyday physiology. It works alongside vitamin K2 MK-7 to steer calcium toward bones and away from arteries, supporting heart and skeletal health.
