Abstract
Soy hydrolysate contains biopeptides that can increase the absorption of iron. The study aimed to analyze the efficacy of a Soy-biopeptide in improving serum iron, serum ferritin and hemoglobin among female adolescents. For the product’s efficacy study, a one-group pre-test—post-test design was conducted. The products were given every day for 14 days. The serum iron, serum ferritin and hemoglobin were measured twice prior to administration and after day 14, for 52 respondents of female adolescent girls who met the inclusion criteria. The results showed that serum iron levels increased significantly from (66.87±32.44) mcg/dl to (103.77±55.87) mcg/dl (p = 0.000) in both groups. Meanwhile, serum ferritin levels increased significantly in the group with serum ferritin levels from (13.29±9.5) ng/ml to (17.48±12.18) ng/mL (p = 0.00), but there was no significant change in the group with serum ferritin levels from (28.06±23.7) ng/ml to (29.05±21.3) ng/ml (p = 0.64).The respondent's hemoglobin level before administration was (12.21±1.29) g/dl and did not change significantly after administration (12.05±1.31) g/dl (p = 0.016). In conclusion, soy-biopeptide has the health benefits of increasing serum iron and serum ferritin levels in respondents with low iron intake and can maintain normal hemoglobin levels.
