Nutritional Information

The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that helps balance minerals and keeps bones healthy.

This form is the natural cholecalciferol variant used to support normal bone, muscle and immune function; it is produced in the body when skin is exposed to sunlight and is also available as a dietary supplement.

What Does Vitamin D3 Do?

Vitamin D3 helps keep normal calcium and phosphorus absorption, supporting bone mineralisation and skeletal strength, and it also supports immune cell activity in line with NHS and EFSA guidance.

Dr. Bouillon from the University of Liège found that adequate vitamin D status is linked with functions that help support skeletal health and immune system activity.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
