The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin vital for normal bone health and immune function. This variant uses Quali-D and is supported by a carrier derived from coconut MCT oil for better stability and absorption.

This ingredient helps the body's natural calcium uptake and bone mineralisation through its part in how calcium and phosphorus are utilised.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake, contributing to the upkeep of normal bones and teeth, muscle function, and immune system activity per EFSA guidance. It supports normal immune responses and muscle performance as part of daily wellbeing.

Dr. Holick from Harvard University found that vitamin D3 raises blood levels of 25(OH)D, boosting calcium uptake and bone mineralisation. This mechanism reinforces the nutrient's part in keeping skeletal health.
