The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, or cholecalciferol, is a fat‑soluble nutrient essential for normal body function and bone health support.

This form is the body’s preferred vitamin D source and is commonly sourced as a pure cholecalciferol ingredient to support daily health needs.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption and supports immune system activity in line with EFSA guidance. Dr. Bischoff-Ferrari of Harvard University found that vitamin D supplementation can improve musculoskeletal strength and reduce fall risk in older adults.

Through its role in mineral metabolism, vitamin D3 contributes to the maintenance of normal bones and teeth and supports overall immune function, aligning with recognised health guidance.
