This open-label study investigates the effects of lecithin-based formulations of Curcumalonga (Meriva™) and Boswellia serrata (Casperome™) extracts on post-acute COVID-19irritable bowel syndrome (PCIBS) and irritable bowel syndrome (IBS) without priorCOVID-19 infection. A total of 44 participants, 16 with PCIBS and 28 controls with IBS,were supplemented for 30 days. Outcomes measured included abdominal bloating, abdominalpain, enteral dysbiosis, and global assessment of efficacy. The study found significantreductions in bloating and pain in both groups, with a notable decrease in dysbiosis onlyin the IBS group. This suggests potential benefits of the supplementation in managinggastrointestinal symptoms associated with PCIBS and IBS.
This study aims to evaluate the efficacy and safety of lecithin-based formulations of
Curcuma longa (Meriva™) and Boswellia serrata (Casperome™) extracts in treating
gastrointestinal symptoms in patients with post-acute COVID-19 irritable bowel syndrome
(PCIBS) and irritable bowel syndrome (IBS) without prior COVID-19 infection. The study
was conducted at the Department of Public Health of the University of Pavia, Italy.
Participants included 16 PCIBS patients and 28 IBS controls, aged 18-75 years. They were
administered 500 mg of Curcuma longa and 150 mg of Boswellia serrata extracts twice daily
for 30 days, in conjunction with a low FODMAP diet. Key outcomes measured were reductions
in abdominal bloating and pain, changes in enteral dysbiosis as indicated by urinary
indican levels, and overall treatment efficacy as assessed by participants. The study
found that both groups experienced significant reductions in abdominal bloating and pain.
However, a notable decrease in enteral dysbiosis was observed only in the IBS control
group. The treatment was well tolerated with no reported adverse effects. These findings
suggest that the combination of Curcuma longa and Boswellia serrata extracts may provide
significant benefits in managing gastrointestinal symptoms associated with PCIBS and IBS.
