Using Iodized Salt to Improve Serum Folate, B12 and Iron Levels

Salt is an ideal vehicle for fortification because its universal consumption and often centrally processed with established distribution channels. Over 70% of households globally have access to iodized salt. Considering the success of salt iodization, it is logical to use the existing infrastructure to provide folic acid and other micronutrients (such as B12 and iron) through this dietary mechanism.

AIM:To assess increase in blood concentrations of folate, B12 and iron among women of reproductive age who consume micronutrient-fortified iodized salt for 3 months.

OBJECTIVES :

• To examine the effect of consumption of iodized salt fortified with folic acid, B12 and iron on serum/plasma concentrations among women of reproductive age.
• To assess acceptance of study salt for daily use during 3 months of consumption.
