The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat‑soluble vitamin involved in everyday calcium metabolism and bone health.

This form of vitamin D is commonly sourced as a dietary supplement to help support everyday intake of this essential nutrient.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake and contributes to keeping normal bone density and teeth.

It also supports immune function in line with EFSA guidance.

Scientific research suggests that keeping adequate vitamin D levels is important for bone mineralisation, with EFSA noting the vitamin’s role in calcium metabolism and skeletal health. Dr. Lips from the University of Copenhagen found that adequate vitamin D status is linked to bone health benefits in adults.
