2. These vitamins also aid in maintaining a healthy immune system by regulating the body's inflammatory response and promoting immune cell function.

The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble nutrient essential for bone and immune health.

This form is the commonly recognised cholecalciferol and is valued for its role in facilitating calcium metabolism and supporting immune function.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption, supporting bone structure and immune function in line with NHS and EFSA recommendations. Dr. Smith of University College London found that vitamin D3 supports calcium metabolism and immune health through these mechanisms.

This activity contributes to normal bone maintenance and immune system function, aligning with approved nutrient function concepts.
