The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, or cholecalciferol, is a fat-soluble nutrient that helps normal bone function and immune system activity. This form is the main circulating type of vitamin D in the body and is commonly delivered with carrier oils in liquid preparations.

This form is cholecalciferol shown in a liquid format with carrier oils like medium-chain triglycerides and safflower oil to help absorption.

What Does Vitamin D3 Do?

Vitamin D3 helps support calcium absorption and the maintenance of normal bone health, with further relevance to immune system function as recognised by health bodies. Scientific research suggests these roles contribute to daily wellbeing and adhering to established intake recommendations.

EFSA and NHS guidance highlight the important physiological roles of vitamin D3 in bone and immune health, aligning with the broad functional description above.
