Research: Reduced Abdominal Pain, Improvements with Constipation and IBS  ⭐⭐⭐⭐

40 IBS patients were randomized to receive either 299V strain (20 patients) or placebo (20 patients) over a period of 4 weeks. All patients treated with 299V strain reported resolution of their abdominal pain as compared to only patients 11 people from a placebo group. There was also improvements in stools frequency in constipated patients in six out of 10 patients treated with LP299V compared with only two out of 11 treated with placebo. With regards to all IBS symptoms an improvement was noted in 95% of patients in the 299V strain group vs 15% of patients in the placebo group.

Research: Reduced Symptoms by 78% ⭐⭐⭐⭐⭐

In a double blind, placebo-controlled, parallel-designed study, 200 IBS patients were randomized to daily receive either one capsule of L. plantarum 299v or a placebo for 4 weeks. After 4 weeks, both pain severity and daily frequency were lower with L. plantarum 299v group than with placebo. Similar results were obtained for bloating. At week 4, 78.1 % of the IBS patients scored the L. plantarum 299v (DSM 9843) symptomatic effect as excellent or good vs only 8.1 % for placebo (P < 0.01). A 4-wk treatment with L. plantarum 299v provided effective symptom relief, particularly of abdominal pain and bloating, in IBS patients fulfilling a scoring system called the Rome III criteria.

Important Crohn’s & Colitis Dietitian Notes:

  • Up to 50% of IBD patients also have IBS which is why we often use this strain with those who experience bloating
  • If bloating is severe and not responsive to this strain we suggest testing with your GI for SIBO or working with an IBD-Dietitian
  • As with all antibiotics, probiotics are best taken 3-4 hours between antibiotic doses so that you can actually get the benefits of a probiotic.
  • Keep in mind there are many “Lactobacillus Plantarum” probiotics out there, but this refers to the 299 strain only
  • Avoid purchasing probiotics that do not list the strain name
