Iron Supplementation and Gut Microbiota
The Impact of Low-Level Iron Supplements on the Faecal Microbiota of Irritable Bowel Syndrome and Healthy Donors Using In Vitro Batch Cultures.
Focuses on IBS and microbiota
We explored how low-level iron supplementation impacts the gut microbiota in individuals with Irritable Bowel Syndrome (IBS) and in healthy donors. To do this, we conducted anaerobic, pH-controlled in vitro batch cultures using fecal samples from both groups, supplemented with various forms of iron, including ferrous sulphate, nanoparticulate iron, and pea ferritin.

Our findings revealed that IBS participants had distinct microbial profiles compared to their healthy counterparts. Interestingly, we observed that the different sources of iron we used did not have a negative effect on the overall microbial populations. Both pea ferritin and nanoparticulate iron showed similar outcomes, while ferrous sulphate appeared to enhance certain beneficial bacteria.

Additionally, we measured the production of metabolites and found that there was no harmful shift towards increased proteolysis. These results suggest that low doses of iron from the three sources tested are unlikely to be detrimental to the gut microbiota, giving us new insights into the potential for iron supplementation in managing gut health, especially for those with IBS.

This is the first time we've tested fermentation of pea ferritin, which adds an exciting dimension to our understanding of dietary iron sources and gut health.

Celiac disease linked to IBS symptoms
Celiac Disease Initially Misdiagnosed as Irritable Bowel Syndrome: Case Report.
Significance in understanding IBS treatment
We explored a fascinating case of a 30-year-old patient who was initially diagnosed with irritable bowel syndrome (IBS) due to vague abdominal symptoms. However, this diagnosis was later challenged when he presented with iron deficiency anemia in our clinic.

Upon further investigation for the cause of his anemia, we discovered he actually had celiac disease, confirmed by positive serological tests and a small bowel biopsy. After starting a gluten-free diet and taking iron supplements, we observed a complete improvement in both his abdominal symptoms and his anemia.

This case brings to light the complexities of diagnosing gastrointestinal issues. It emphasizes the need for routine screening for celiac disease in patients who may present with symptoms that could easily be misattributed to IBS—especially when iron deficiency anemia is involved.

More energy
Very good! I feel the difference when I take the iron. I have more energy and no bowel problems.

No side effects
I've bought this iron multiple times, and it works. The price and quality are excellent. I definitely recommend it. There were no side effects, and my gastrointestinal tract tolerates this iron well. My ferritin level rose to 82 in three months! Currently, iron bisglycinate is regarded as one of the best compounds—it's highly effective with no side effects. Don't forget to take vitamin C to absorb iron. My hair loss has stopped, and my Chronic Fatigue Syndrome has improved significantly.
