Consumption of probiotics, prebiotics, and synbiotics in different types of iron deficiency and their effects on iron status
Type of iron deficiency | Probiotic strain/Prebiotic type | Reported effect |
---|---|---|
Impaired iron absorption | Lactobacillus plantarum FS2 | ↑ iron bioavailability by 128–372% [57] |
Low iron bioavailability | Bifidobacterium bifidum, B. longum | ↑ iron absorption [41] |
IDA | L. plantarum 299v | ↑ iron absorption [58, 59] |
IDA | Streptococcus thermophilus | ↑ iron uptake and utilization (improved hemoglobin, serum iron, total iron-binding capacity, ferritin) [60] |
IDA | L. fermentum | Delivers iron nanoparticles to enterocytes, ensuring adequate iron uptake [61] |
IDA | L. acidophilus | ↑ serum ferritin and ↑ iron absorption [62] |
IDA | L. plantarum 299v + iron + vitamin C | ↑ blood iron levels [63] |
IDA | L. plantarum Dad 13 | No difference in iron status or gut microbiota profile [49] |
Iron metabolism disorders associated with obesity | Multistrain probiotic (B. bifidum W23, B. lactis W51/W52, L. acidophilus W37, L. brevis W63, etc.) | May affect iron metabolism in postmenopausal women with obesity; further research is required [51] |
Menorrhagia-related anemia | L. plantarum 299v + iron | ↑ iron absorption [64] |
IDA | GOS + inulin | Improved immune function in iron-deficient women [65] |
IDA | FOS and GOS | ↑ iron bioavailability [66] |
IDA | Inulin | ↑ iron sulfate bioavailability; ↓ calcium absorption [67] |
IDA | GOS | ↑ iron absorption [68] |
IDA | Inulin + oligofructose | ↑ DMT1 expression in the cecum, ↓ ferroportin expression in the duodenum, supports intestinal iron regulation [69] |
Celiac disease-associated anemia | Inulin enriched with oligofructose | ↓ serum hepcidin; ↑ iron absorption [70] |
IDA | B. lactis HN019 + oligosaccharides | ↓ risk of anemia and iron deficiency [71] |
IDA | B. bifidum, B. longum + GOS | ↑ iron absorption [42] |
+: and; ↑: increase; ↓: decrease; DMT1: divalent metal transporter 1; FOS: fructooligosaccharides; GOS: galactooligosaccharides; IDA: iron deficiency anemia
