Mineral absorption - hematology/anemia
Research Projects
- Hematology
- Dr. Swain's research focus is on mineral absorption/anemia, especially bioavailability of elemental and heme iron powders, which are often used as food fortificants, and the ability of these iron powders to correct anemia. Dr. Swain's research findings and publications in this area are highly valued internationally in that they provide guidance for mineral food fortification programs globally.
