Mushroom supplement tested for gut health and mood boost
NCT ID NCT07027462
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a mushroom blend can help with occasional stomach issues like bloating and constipation, and also improve mood. Forty healthy adults aged 30 to 60 who sometimes had digestive discomfort took either the mushroom supplement or a placebo. Researchers checked changes in gut bacteria, digestion symptoms, and mood over time.

- mushroom blend
- What this could lead to
- If it works, this could point toward a natural supplement to ease occasional bloating, gas, or constipation and improve mood.
- What could go wrong
- This is a small, early study in healthy people, so results may not apply to others. The supplement may have no real benefit over placebo.
