Specific gut microbial metabolites (SCFAs, Bile Acids, Tryptophan derivatives) stimulate GLP-1 secretion from intestinal L cells via specific receptors (FFAR2/3, TGR5, GPR142).
Consuming fiber (for SCFAs), specific fermented foods (for BAs), and tryptophan-rich foods can naturally boost GLP-1 by activating specific gut receptors. This supports metabolic and musculoskeletal health.
GoodSupportsHIGH confidence
SCFAs activate GPRs, such as free fatty acid receptor 2 (FFAR2) and free fatty acid receptor 3 (FFAR3) (also known as GPR43 and GPR41), on L cells. Particularly, the Gq-coupled FFAR2 triggers an influx of intracellular calcium ions (Ca²⁺), which promotes GLP-1 exocytosis.
