Significantly less gastrointestinal side effects were reported with lactoferrin treatment .
No significant differences existed with regard to other outcomes .
In conclusion , for pregnant women with IDA , daily oral bovine lactoferrin is just as good as ferrous sulfate in improving hematological parameters with fewer gastrointestinal side effects .
This systematic review and meta- analysis aim ed to evaluate the efficacy of daily oral bovine lactoferrin versus daily oral ferrous iron preparations for treatment of iron deficiency anemia ( IDA ) during pregnancy .
Oral administration of lactoferrin increases hemoglobin and total serum iron in pregnant women.
Iron deficiency anemia ( IDA ) during pregnancy continues to be of world-wide concern . IDA is a risk factor for preterm delivery and subsequent low birth weight , and possibly for poor neonatal health . Iron supplementation in pregnancy is a widely recommended practice , yet intervention programs have met with many controversies . In our study , 300 women at different trimesters of pregnancy were enrolled in a trial of oral administration of ferrous sulfate ( 520 mg once a day ) or 30 % iron-saturated bovine lactoferrin ( bLf ) ( 100 mg twice a day ) . Pregnant women refusing treatment represented the control group . In this group hemoglobin and total serum iron values measured after 30 d without treatment decreased significantly , especially in women at 18 - 31 weeks of pregnancy . In contrast , after 30 d of oral administration of bLf , hemoglobin and total serum iron values increased and to a greater extent than those observed in women treated orally for 30 d with ferrous sulfate , independently of the trimester of pregnancy . Unlike ferrous sulfate , bLf did not result in any side effects . These findings lead us to hypothesize that lactoferrin could influence iron homeostasis directly or through other proteins involved in iron transport out of the intestinal cells into the blood
