The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, the biologically active form of vitamin D, supports normal bodily function related to bone and immune health. This formulation uses a softgel with an oil base to aid stability and absorption.

In this product, the ingredient is presented as Vitamin D3 (cholecalciferol), a fat-soluble nutrient that is produced in the skin and plays a key role in calcium and phosphorus metabolism.

What Does Vitamin D3 Do?

Vitamin D3 participates in the regulation of calcium and phosphorus balance, contributing to bone health and immune system function. It enhances gut calcium absorption and supports normal immune responses, aligned with expert guidance from Dr. Holick of Boston University.

This single nutrient therefore supports normal bone maintenance and immune function through its involvement in mineral metabolism and immune activity.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
