Do I Have Adrenal Fatigue? And How Can I Help It Naturally?
Alive and Well · April 7, 2022 · 1 min read
'Adrenal fatigue' is a controversial term in conventional medicine, but the underlying phenomenon (a dysregulated stress response system that leaves you exhausted, wired-but-tired, and running on empty) is very real. Here's what the evidence shows and what you can do about it.
Understanding HPA Axis Dysfunction
The more accurate term is HPA axis dysregulation (hypothalamic-pituitary-adrenal axis). Under chronic stress, the HPA axis initially produces excess cortisol. Over time, with prolonged activation, the system begins to dysregulate. Cortisol patterns become abnormal, the system becomes less responsive, and the adrenal glands may become functionally exhausted.
Symptoms of HPA Axis Dysregulation
- Profound fatigue, especially in the morning
- 'Wired but tired': exhausted but unable to relax or sleep
- Energy crashes in the afternoon
- Craving salt and/or sugar
- Difficulty recovering from stress or illness
- Brain fog and poor concentration
- Mood instability, anxiety, or depression
- Reduced stress tolerance
Testing for HPA Axis Dysfunction
The gold standard is a 4-point salivary cortisol test, measuring cortisol levels at four points throughout the day to assess the diurnal cortisol curve. This reveals whether cortisol is elevated, depressed, or following an abnormal pattern. DHEA-S levels provide additional information about adrenal reserve.
Natural Support Strategies
Adaptogens: Ashwagandha, rhodiola, and eleuthero (Siberian ginseng) are evidence-backed for supporting adrenal function and stress resilience.
Nutrient support: Vitamin C, B5 (pantothenic acid), magnesium, and zinc support adrenal function.
Lifestyle fundamentals: Sleep, stress reduction, and blood sugar stability are non-negotiable for HPA axis recovery.
Reduce stimulants: Caffeine further stimulates the HPA axis, so limiting consumption supports recovery.
