Algae supplements may aid in digestion and diminish problems in the gut, especially for those who suffer from irritable bowel syndrome, according to a new study.

A study researchers at University of California San Diego published in Journal of Functional Foods found Chlamydomonas reinhardtii, a type of algae commonly researched throughout science, may be useful in treating IBS — a disorder that affects the large intestine.

Researchers initially examined the algae’s effect on the gut by examining its impact on mice with acute colitis — or inflammation of the stomach lining. Among mice given algae, scientists saw a reduction in the rate of weight loss, which is a common symptom of acute colitis.

Then researchers examined 51 people with IBS. They were given algae dosages of one milligram or three milligrams. Researchers collected surveys on their gut health over a period of 30 days.

Participants reported less IBS symptoms, including bowel discomfort, diarrhea, gas, and bloating. These IBS sufferers also reported more regular bowel movements. Even those who had less frequent IBS symptoms reported a decreases in overall gastrointestinal symptoms.

More research is needed, scientists said.
