This site's own benefits section lists this specific third point directly: stated on the label alongside memory; Bacopa is also studied for stress response.
Worth reading this as this site's own clarification that mood support, like memory support, traces back to the same named ingredient — Bacopa — rather than to a separate, unnamed compound.
This site's own Bacopa citation covers memory recall trials specifically — worth reading this mood-and-stress-response claim as a related but distinct area of Bacopa research, worth checking independently.
