The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, often called cholecalciferol, is a fat-soluble nutrient essential for normal bodily functions linked to bone health and immune support.

This form is a single-ingredient vitamin D3, sourced as the active nutrient that enables calcium utilisation and supports musculoskeletal and immune system activity.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake and supports immune function, contributing to overall immune health and bone maintenance per EFSA guidance.
