Texas Christian University

Texas Christian University (TCU) is a research organization currently conducting clinical trials relevant to the functional beverage industry.

Notably, TCU is conducting clinical trial NCT07105826, which evaluates the acute effects of popular prebiotic sodas—specifically olipop and poppi—against traditional caloric and non-caloric sodas. The trial aims to test the hypothesis that the high fiber content in these prebiotic beverages ferments via the gut microbiota to produce short-chain fatty acids (SCFAs), thereby naturally stimulating endogenous-glp-1-secretion and enhancing satiety without causing significant glucose or insulin spikes.
