Bio-Vitamin D3 from Pharma Nord contains vitamin D3 dissolved in cold-pressed olive oil and encapsulated in small, easy-to-swallow “pearls” of soft gelatine. Vitamin D contributes to normal functioning of the immune system, contributes to the maintenance of normal teeth and bones, supports normal muscle functioning, and plays a role in the body’s cell division and specialisation. When UV rays hit the skin, the active form of vitamin D is formed. The body’s ability to produce vitamin D is reduced with age, however the vitamin D synthesis is inhibited by lack of sunshine or covering up with clothes. Pregnant and breast-feeding mothers, young children, elderly people and those with dark skin may also require supplemental vitamin D due to inadequate UV exposure.
