Consuming the green algae C. reinhardtii improves gastrointestinal issues associated with irritable bowel syndrome (IBS) such as diarrhea, gas, and bloating, according to a new study published in the Journal of Functional Foods.

For years, researchers led by Stephen Mayfield, PhD, principal investigator and algae expert from the University of California San Diego, have been exploring C. reinhardtii as a cost-competitive and sustainable source of valuable plant-based products, specifically pharmaceuticals and biofuels. In the current study, they turned their attention towards investigating the algae as a nutritious food additive for improving human health.



Results showed that participants who suffered from a history of frequent gastrointestinal symptoms reported significantly less bowel discomfort and diarrhea, significantly less gas or bloating, and more regular bowel movements.
