A Study to Evaluate the Effects of a Supplement on Gut Comfort in GLP-1 Receptor Agonist Users

This is a randomized, triple-blind, placebo-controlled, virtual clinical trial evaluating the effects of the Oxxynea® botanical supplement on gut comfort in adults who use GLP-1 receptor agonists (GLP-1 RAs). Seventy participants experiencing gastrointestinal discomfort associated with GLP-1 RA use will be randomized to receive either Oxxynea® or a matching placebo once daily for six weeks. Participants will complete questionnaires at Baseline, daily for the first 14 days, and at the end of Weeks 2, 4, and 6. The primary measure is change in gastrointestinal comfort assessed by the Gastrointestinal Quality of Life Index (GIQLI). Secondary measures include quality of life, participant-perceived product benefits, and specific GI symptom changes (nausea, abdominal pain, bloating, diarrhea, and constipation).

Multi-strain Probiotic Supplement for Digestive Comfort and Well-being in Healthy Women

This study looks at whether a daily probiotic supplement can help improve mild-to-moderate stomach and digestive symptoms, such as gas and bloating, in women who also experience symptoms commonly associated with hormonal fluctuations. Participants take either the probiotic or a placebo (a look-alike capsule with no active ingredients) once a day for 8 weeks, without knowing which one they are taking. Researchers will compare changes in digestive comfort, sleep, energy, and mood between the two groups over the study period. The study is conducted entirely online, so participants can take part from home.

Evaluation of Gut-Related Well-Being and Mood Effects of a Daily Nutritional Food Ingredient From the Co-Fermentation of Fungal Mycelium (Pleurotus Pulmonarius) and Microalgae (Chlorella Vulgaris)

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
