16 Jul 2020 --- SHIFT20 has concluded, but the stand-out ingredients presented still resonate with industry. At the virtual show, multinational Comet Bio showcased a randomized, placebo-controlled, crossover clinical trial, which evaluated the gastrointestinal (GI) tolerability and prebiotic effects of arabinoxylan. The results found that consumers can take up to 12 g of the plant fiber extract, marketed as Arrabina, per day, with no negative gut or bowel reaction. Furthermore, the trial revealed that the fiber ingredient promotes the growth of Bifidobacteria, further proving its prebiotic potential.
