The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin essential for supporting normal bone and immune health. This liquid delivery format aims to support rapid absorption through a simple oil-based carrier system.

This form is commonly supplied with a carrier such as MCT or olive oil to aid absorption and bioavailability, helping to maintain consistent vitamin D3 activity in the body.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium and phosphate utilisation, supporting bone mineralisation and overall skeletal health. It also participates in immune system modulation, aligning with EFSA guidance on nutrient function.

Dr. Holick of Harvard University found that vitamin D3 supplementation supports healthy immune function and helps maintain strong bones by optimising calcium absorption.
