Nutritional Information

The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, or cholecalciferol, is a fat-soluble nutrient that supports bone health and immune system function. This liquid formulation uses a fat-based base to aid absorption of the nutrient, commonly provided as a readily utilisable form of vitamin D3.

This form is present within a matrix designed to optimise uptake via the fat-soluble pathway, helping to ensure efficient utilisation of the vitamin for bodily functions tied to mineral balance and immune regulation.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption and supports bone mineralisation, while also contributing to immune system function in line with EFSA guidance.

Dr. Holick of Harvard University found that vitamin D3 supplementation can support bone health and immune function, illustrating the nutrient’s role in maintaining healthy physiological processes.
