Food ingredient of oyster mushroom mycelium (Pleurotus pulmonarius) and microalgae (Chlorella vulgaris): Food ingredient obtained from the co-fermentation of oyster mushroom mycelium (Pleurotus pulmonarius), microalgae (Chlorella vulgaris) and added bamboo fibre with flavours for better palatability

Study summary

The purpose of the study is to evaluate the gut-related well-being and mood effects of a food ingredient obtained from the co-fermentation of oyster mushroom mycelium (Pleurotus pulmonarius), microalgae (Chlorella vulgaris), and bamboo fibre in healthy adults (aged 18+) experiencing minor gastrointestinal discomfort during an intervention period of 30 days. The participants will be allocated into two unbalanced groups to determine relationships between the measurable outcomes and the dose levels at three different time points: start of the study (baseline), 15 days (middle), and 30 days (end-point), during which participants will be asked to complete GSRS and POMS-2-SF questionnaire

Primary outcome measure(s)

Change in Gastrointestinal Symptom Rating Scale (GSRS) Total Score — Baseline (Day 0) to Day 30
The primary outcome is the change in gastrointestinal symptom severity as measured by the Gastrointestinal Symptom Rating Scale (GSRS). The GSRS is a validated self-report questionnaire assessing the severity of common gastrointestinal symptoms. Change in total GSRS score will be evaluated over the course of the 30-day intervention to assess the effect of the investigational food ingredient on gut-related well-being.
