About Piper longum
Ayurvedic pepper (pippali) rich in piperine; used mainly as a bioavailability enhancer (piperine inhibits certain metabolizing enzymes and P-gp) rather than for a standalone benefit. Standalone clinical evidence is minimal and mechanistic; most human data concern piperine's effect on co-administered nutrients.
