The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that's essential for everyday bodily functioning and health upkeep. This form is commonly used in supplements to support your vitamin D status and related metabolic processes.

In multivitamin formulas, Vitamin D3 is provided in a bioavailable form to help support your body’s needs for bone health and immune support, among other roles noted in scientific resources. The product aims to deliver a broad base of nutrients in a bioavailable format to help overall metabolic health.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium metabolism, supporting normal bone mineralisation and immune function in line with EFSA guidance. It contributes to maintaining healthy teeth and skeletal health as part of a balanced diet.

EFSA notes that adequate Vitamin D3 status supports essential functions and overall health maintenance within the context of a varied diet and healthy lifestyle.
