A new clinical study in Nutrients demonstrates that ZenGut, a natural microalgae extract developed by Microphyt, “significantly improves” gut microbiota balance, relieves digestive discomfort, and enhances mood and mental well-being in healthy adults. The randomized, double-blind, placebo-controlled trial involved 56 adults aged 18–55 with mild to moderate gastrointestinal (GI) distress. Each received 250 mg/day of ZenGut — sourced from the Tetradesmus obliquus Mi175.B1.a strain — or a placebo for four weeks.
