Around the world, billions of people live with vitamin and mineral deficiencies. For instance, approximately one third of the developing world’s children under the age of five are vitamin A-deficient, and therefore ill-equipped for survival. Iron deficiency anaemia during pregnancy is associated with 115,000 deaths each year, accounting for one fifth of total maternal deaths.
