 In this study, wheat bran extract, WBE, was found to be safe and well tolerated when taken at dosages up to 30g per day. The results showed that WBE had positive effects on stool characteristics such as stool pH and stool moisture concentration, which are indicators of increased colonic fermentation. Furthermore, WBE also appeared to reduce the occurrence of certain gastrointestinal symptoms. On the other hand, oligofractors had similar effects on stool characteristics but caused more GI discomfort than WBE.
