The sunshine vitamin — essential for calcium absorption, bone mineralisation, immune modulation and mood. Most UK adults are chronically insufficient, particularly through autumn and winter.
Why this form
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.
Key benefits
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.
Mood & cognitive function
Vitamin D receptors are expressed in areas of the brain associated with normal psychological function and cognitive performance. Most UK adults have insufficient vitamin D levels, particularly through the autumn and winter months.
