The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin vital for bone health and immune function. This nutrient happens naturally in animal-based sources and is considered highly bioavailable for the body's use.

This form is sourced from natural sources and supports calcium metabolism, contributing to the normal functioning of bones and teeth.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption and supports normal bone health, with guidance from EFSA and NHS emphasising its role in calcium metabolism.

It helps maintain mineral balance in your body, which underpins healthy bone structure and function.
