This form is commonly supplied as cholecalciferol and helps availability of vitamin D in the body, contributing to the maintenance of normal bone and immune function, with absorption and utilisation described in EFSA guidance.

What Does Vitamin D3 Do?

Vitamin D3 helps balance calcium and phosphorus metabolism and supports bone health as well as immune function, aligning with EFSA and NHS guidance.

In the body, vitamin D3 is converted to calcitriol, which helps boost mineral absorption and modulate immune responses, a mechanism backed by science.
