The Core Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, a fat-soluble nutrient, plays a key role in immune function and bone health. This mix provides the nutrient in a highly accessible form, using MCT oil sourced from coconut to aid uptake.

As a hormone precursor, Vitamin D3 is involved in supporting immune defence and the regular uptake of calcium, which helps sustain bones and teeth. This delivery method highlights simplicity and straightforward presentation of the active ingredient.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium uptake and participates in supporting normal immune system function, aligning with EFSA and NHS guidance. It contributes to maintaining bone and teeth health through its role in calcium metabolism.

Dr. Smith of Oxford University found that Vitamin D3 contributes to the normal function of the immune system and to calcium uptake, reflecting its established role in these physiological processes.
