The nutrient deficiency impacts more than half the world's population - more than four billion people - disproportionately impacting many women and their offspring. "The high number of people - especially women - living with folate inadequacy is both surprising and somewhat disheartening, considering how many countries have implemented folate fortification programs," says Jean Francois Jeanne, manager of the Gnosis Substantiation Team.
