What is Vitamin D3?
The sunshine vitamin — contributes to normal absorption of calcium, the maintenance of normal bones, and the normal function of the immune system. Most UK adults have insufficient intake, particularly through autumn and winter.
Why Cholecalciferol (D3)?
Sourced from Cladonia rangiferina (reindeer lichen) — the richest known natural vegan source of cholecalciferol — providing the biologically active D3 form with identical efficacy to conventional lanolin-derived D3, without any animal byproducts.
What are the benefits of Vitamin D3?
Calcium absorption & bone mineralisation
Vitamin D3 upregulates calcium-binding proteins in the intestine, increasing calcium absorption from food. Adequate D3 is essential for normal bone mineralisation alongside sufficient calcium intake.
Immune system function
Virtually all immune cells express vitamin D receptors. D3 contributes to the normal function of the immune system, supporting both innate and adaptive immune responses.
Muscle function
Vitamin D contributes to normal muscle function. Most UK adults have insufficient vitamin D levels, particularly through the autumn and winter months.
