Introduction:

one of the causes of Nutritional anemia is that the amount of iron absorbed is insufficient to meet the body's needs.

Objective:

to determine the effects of microencapsulated and heminic iron supplementation to increase hemoglobin levels and body weight in iron-depleted rats.

Methods:

a randomized experimental study was designed. Four study groups were formed. Control group (GC), experimental group (GE1) (MC microencapsulated iron supplementation), experimental group 2 (GE2) (heminic iron supplementation) and experimental group 3 (GE3) (MC + heminic iron supplementation). A dry powdered diet containing all normal nutrients except iron was fed to the four groups for 15 days (three times a day). Weight, length and hemoglobin (Hb) were evaluated at pre- and post-test under similar conditions.

Results:

in Hb, no significant differences were observed in the CG (p = 0.225), despite a -9.6 % decrease in the post-test. GE1 significantly increased hemoglobin (14.3 %, Hb 2.1 g/dl) and body weight (21.6 %, 25.8 g) (p < 0.05) in the post-test. Similarly, GE2 significantly increased hemoglobin (14.5 %, Hb 2.1 g/dl) and body weight (44.5 %, 52.3 g) (p < 0.05). However, in GE3, despite significantly increasing weight (30.2 %, 35.2 g), the increase in hemoglobin levels was similar to what occurred in GE1 and GE2 groups (increasing by 14.5 % and Hb 2.2 g/dl). There were no significant differences in rat length between pre- and post-test in the four groups.

Conclusion:

these RESULTS suggest that heme iron together with quinoa and cañihua flour could be exploited as a new safe and efficient iron supplement compared to microencapsulated iron, given its higher iron bioavailability and its ability to increase body weight.
