Prebiotic: GI Dysfunction/Cold-Flu

Nutraceutical: Prebiotic supplement (galactooligosaccharide)
 
Indication: GI dysfunction and cold/flu
 
Source: Am J Clin Nutr, June 2011;3(6):1305-11.
 
Research: This randomized, double-blind study included 419 college students who were randomized to receive 0, 2.5 or 5 grams of a galactooligosaccharide prebiotic supplement for 8 weeks—before, during and after final exams.
 
Results: Study participants showed fewer symptoms of gastrointestinal problems, including diarrhea, constipation, indigestion and abdominal pain following prebiotic supplementation. It was also found that normal-weight individuals receiving the 5-gram prebiotic supplement experienced a 40% reduction in days with cold or flu, although no effect was observed in overweight or obese participants. These findings suggest that galactooligosaccharide prebiotics may provide beneficial protection during times of increased stress.
