The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin essential for normal bone and immune function. This form is the natural vitamin D produced in the skin upon sunlight exposure.

This capsule contains Vitamin D3 formulated for absorption in sunflower seed oil, with a vegetarian capsule shell to support uptake and suitability for a plant-based diet.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption, supporting bone structure and strength, and it is involved in muscle and nerve function as part of normal physiology. It also supports immune function, in line with public health guidance.

Formulated to mirror natural fat-assisted absorption, Vitamin D3 is activated in the body to support maintenance of normal vitamin D levels when sunlight exposure or dietary intake is limited.

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