Elevated or dysregulated orexin signaling is one of the most significant barriers to sleep onset, particularly in individuals under chronic stress or cognitive overload. PeptiSleep™ supports healthy downregulation of orexin pathway activity — supporting the neurological transition from wakefulness to sleep onset.* This mechanism is distinct from and complementary to GABAergic calming — addressing the wakefulness signal rather than simply adding an inhibitory counterbalance.*\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"83:1-83:321;5174-5494\"\u003eCortisol Modulation: Elevated evening cortisol is a primary driver of sleep onset difficulty and fragmented sleep architecture.
