One study was conducted to see if patients with IBS have intestinal flora imbalance and if their gut flora can be modified by supplements.
The patients were randomized into two groups, a test group that received Lactobacillus plantarum and the placebo group.
- Flatulence significantly reduced in the test group
- Enterococci stayed unchanged in the test group and increased in the placebo group
- Test group patients maintained a better overall GI function than control patients
The results indicate that the administration of Lb. plantarum with known probiotic properties decreased IBS symptoms such as pain, bloating, and flatulence. (1)
Another study reported a significant beneficial effect of the specific probiotic treatment.
In this clinical study, patients consumed a test product containing Bifidobacterium lactis. Distension, bloating and other IBS symptoms were assessed. Results showed that the test product consumption significantly improved overall symptom severity and reduced distention. (2)
In one clinical trial, subjects in the group that consumed probiotic products had significant improvements. The Bacillus coagulans-based product was effective in improving the quality of life and reducing gastrointestinal symptoms. (3)
- A combination of Lactobacillus acidophilus and Bifidobacterium lactis in one study showed that it may be helpful in easing bloating symptoms.
Results showed a significant decrease in bloating in the probiotic group in comparison to the placebo group, both at 4 weeks and 8 weeks.
This change represents a 15% reduction in clinical bloating symptoms in the intervention group. (4)
Probiotics are not called “good bacteria” for no reason, however, the effects of probiotics may vary.
Specific probiotics will have different effects on different patients. A probiotic that works for one person or a specific symptom may not work for somebody else or a different indication or different symptom. This is all individual.
The important thing is that the product is taken in adequate doses on a regular basis.
