The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, or cholecalciferol, is a fat-soluble vitamin that supports normal bodily functions including mineral metabolism. This form is used by the body to help maintain health-related processes linked to energy and immunity.

This form can be derived from natural sources and is commonly included in multivitamin/mineral complexes to support metabolic function and overall nutritional status.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption, contributing to normal bone and teeth health, and supports immune function in line with NHS and EFSA guidance.

In addition, vitamin D3 participates in maintaining normal muscle function and supporting other metabolic processes as described in European and UK nutrition resources.

Compliance statements reflect that the product includes a broad micronutrient profile to support metabolic health and satiety-related nutrition needs, with other ingredients such as zinc, chromium and fibre contributing to broader nutritional balance.
