Cortisol, AM

What it isCortisol is the body's primary glucocorticoid, produced by the adrenal cortex under pituitary direction. It peaks within 30–60 minutes of waking — the cortisol awakening response.

DoesMobilizes glucose, modulates immune, sharpens focus, and drives the circadian arousal pattern.

GoodA robust morning cortisol signal predicts strong daytime energy and intact stress response.

BadPersistently elevated AM cortisol drives insulin resistance, visceral fat, sleep disruption, immune suppression, and bone loss. Very low AM cortisol signals adrenal insufficiency or HPA axis suppression.

Standard: AM 6.2–19.4 µg/dL.
Optimal: 12–18 µg/dL AM (narrow target)
Modifiers: Highest within 30–60 minutes of waking; suppressed by exogenous steroids; rises with stress.

How to optimize

Lifestyle: Sleep 7–9 hours with consistent timing; morning sunlight; stress management (meditation, breathwork); avoid late-evening intense exercise.
Diet: Avoid extreme caloric restriction; adequate carbs; reduce caffeine if AM cortisol is elevated.
Supplements: Ashwagandha (600mg/day), phosphatidylserine (300–600mg/day, particularly before bed), magnesium glycinate (300–400mg/day).
Peptides: Selank, semax may modulate stress response.
Drugs: Treat underlying cause; hydrocortisone replacement for adrenal insufficiency.
