Benefits

Vitamin D is widely recognised for its critical role in supporting bone health and immune function, but its impact extends far beyond these areas. A deficiency in this nutrient is surprisingly common, affecting up to 40% of the population, particularly in regions with limited sun exposure or during the winter months.
