The Let’s be Well Red study was conducted to determine the effect of iron-supplement bars (containing 14 mg Fe) on anemia status in urban Indian women of reproductive age. The intervention group was given one daily iron-supplement bar and the control group received none, while both groups received anemia education. After 90 days, researchers found that hemoglobin increased and anemia was reduced among participants who received the iron-supplement bar.
