The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin essential for bone and immune health.

This form is commonly supplied as a bioavailable cholecalciferol supplement intended to support overall vitamin D status.

What Does Vitamin D3 Do?

Vitamin D3 is converted in the liver to calcidiol and in the kidneys to calcitriol, the biologically active form that binds to vitamin D receptors to help regulate calcium and phosphorus balance.

This supports calcium absorption and bone mineralisation and may assist immune function in line with NHS and EFSA guidance. Dr. Holick of Harvard University found that calcitriol increases calcium and phosphate absorption from the gut, promoting bone health and immune modulation.
