Summary
Brief summary
The aim of the study is to assess the tolerability and efficacy of a herbal powder preparation for gastrointestinal disturbances.
Gastrointestinal problems in the upper and lower gastrointestinal tract can manifest as frequent reflux or irritable bowel symptoms. The Nutrition Care Gut Relief Formula contains a mixture of herbs and nutrients which have been shown to be beneficial for the gastrointestinal system.
