Prebiotics On Human Iron Absorption

Iron deficiency is the more common nutritional deficiency, especially in Asian women. Oral iron supplementation is the recommended first-line treatment. It is also used as a preventive measure. Even so, the problem persists. Supplementation may require enhancers of iron absorption to improve its outcomes. In my earlier blog, I explained the potential roles of prebiotics in our diet. In this post, I may add another to the list. 

 

 

Scientific literature proposes that prebiotics can enhance iron absorption, but lacks significant interpretation. A recently published narrative review of human trials tried to summarize the existing evidence on the effects of prebiotics on human iron absorption.[1] Eleven published articles were identified as of November 2021. While inconsistencies between the studies and results exist, convincing evidence exists for the prebiotics galacto-oligosaccharides and fructo-oligosaccharides improved iron absorption with the commonly used iron compound ferrous fumarate, in anemic, adult women and infants.[1] More research investigating the optimal combination of prebiotic, iron compound and dose as well as the effect of long-term application on iron status outcomes is needed.
