Plenibiotic™ stands out as a clinically supported postbiotic ingredient that bridges digestive and skin health through the gut–skin axis. Backed by multiple human studies, Plenibiotic™ has demonstrated benefits for skin hydration, digestive function, and the management of gastrointestinal side effects associated with weight-loss therapies (GLP-1). Its inherent stability across processing conditions, combined with a low effective dose (50 mg for digestive support and 100 mg for skin benefits), makes it an ideal ingredient for innovative supplement and functional food formulations.
