Brief Summary:

The investigational study product used in this clinical trial is a soft drink containing an arabinoxylan-oligosaccharides (AXOS) preparation extracted from wheat bran (hereafter called Wheat Bran Extract, WBE).

The objective of this study is to analyze the effect of the intake of two WBE doses on various parameters of gastrointestinal health. Additionally, safety was analyzed using treatment emergent Adverse Events (AEs) and clinical blood parameters.
