Vitamin D3, also called cholecalciferol, is a fat-soluble nutrient important for maintaining healthy bones and immune health. This form is the main circulating vitamin D in the body and acts as the precursor to calcitriol, a hormone that regulates calcium and phosphorus uptake.

This version is involved in calcium absorption and bone mineralisation, and it also plays a role in supporting immune function and muscle strength as part of everyday physiology.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption, contributing to solid bone structure and mineralisation, while also supporting immune system function as recognised by health authorities.

Dr. Martineau of the University of Cambridge found that vitamin D3 is involved in immune function, aligning with EFSA guidance on its role in maintaining normal immune responses. This evidence supports vitamin D3’s broad role in body physiology.

This supplement isn't meant to diagnose, treat, cure, or prevent any disease.
