Ginger, Stress, and Cortisol: Documented Adaptogenic Effects

Chronic stress elevates cortisol, increases inflammation, and disrupts blood sugar, sleep, and immunity. Ginger acts on several of these mechanisms.

Action on the HPA axis

Gingerol reduces HPA axis hyperactivation during chronic stress in animal models. It decreases plasma cortisol and modulates glucocorticoid receptor expression.

Effects on serotonin and GABA

• Serotonin: Gingerol partially inhibits 5-HT reuptake → anxiolytic effect
• GABA: Increases GABAergic activity → main inhibitory/relaxing neurotransmitter
• Cerebral NF-κB: Brain inflammation amplifies anxiety — gingerol reduces it

INTI's virtuous anti-stress cycle

INTI on an empty stomach in the morning: 0 added sugar → no glycemic spike → no reactive post-sugar cortisol. This is the exact opposite of GIMBER (34g sugar/100ml) which generates an insulin spike followed by a cortisol rebound.
