What the study is about

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
