The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, sometimes called cholecalciferol, is a fat-loving vitamin essential for healthy bones and immune health.

This variant delivers Vitamin D3, the typical nutrient used to support calcium uptake and immune function in the body.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake, supporting bone health and overall skeletal shape, while also supporting immune system function in line with NHS and EFSA guidance.

Dr. Aranow of Yale University found that vitamin D receptors sit on immune cells, indicating a role in the immune response. This supports normal immune function through the activity of vitamin D in the body.
