Vitamin D3, also called cholecalciferol, is a fat-soluble nutrient that backs essential body functions related to bones and immune health. This form is cholecalciferol, the nutrient found in a high-potency supplement to help with calcium control and general skeletal maintenance.

Vitamin D3 helps with calcium absorption and bone mineralisation, supporting bone structure and strength. It also supports immune function and muscle performance, in line with EFSA and NHS guidance. Dr. Bischoff-Ferrari of University of Zurich found that vitamin D3 can support muscle function and immune-related processes when levels are adequate. This supplement is not intended to diagnose, treat, cure, or prevent any disease.
