Natural HPA Axis Modulators — Cortisol & Stress

MECHANISM OVERVIEW

The HPA (hypothalamic-pituitary-adrenal) axis is the central stress response system — chronic activation leads to cortisol excess, hippocampal atrophy, immune suppression, and accelerated aging.

The HPA axis controls cortisol release in response to physical and psychological stress. Chronic activation — common in modern lifestyles — leads to glucocorticoid receptor desensitisation, hippocampal atrophy, adrenal fatigue, immune dysregulation, and metabolic disruption. Adaptogenic compounds that normalise HPA axis function reduce cortisol without blunting acute stress responses. The following are ranked by clinical evidence from the BiohacksAI corpus.
