Vitamin D3, which is also called cholecalciferol, is a fat‑soluble vitamin vital for bone growth and immune health in kids.

This form comes from natural lanolin and stays suspended in MCT oil to help absorption.

What Vitamin D3 Does?

Vitamin D3 helps regulate calcium uptake for normal bone growth and supports immune function in kids. Dr. Jolliffe from University of Oxford found that vitamin D lowers rates of acute respiratory infections in kids, showing broader immune support.

Evidence from EFSA-aligned research backs the role of vitamin D in keeping normal calcium levels and bone health during growth.
