Adrenal, cortisol rhythm & stress-driven fatigue
One of 4 mechanistic pathways to 🔋 Energy & fatigue · 16 options
'Adrenal fatigue' is not a diagnosis and the glands rarely fail. What is real is a flattened cortisol curve — low morning, high evening — which produces exactly the tired-but-wired pattern people describe. It is measurable with a four-point salivary test.
The rhythm is the diagnosis, not the level. Worth being blunt: 'adrenal fatigue' is not a recognised condition and the glands rarely fail — but a flattened cortisol curve is real, measurable and treatable.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
🧬 Ashwagandha
Lowers evening cortisol and improves perceived stress and fatigue in multiple RCTs. The best-evidenced option here.
🧬 Rhodiola
Specifically trialled in burnout and fatigue syndromes with positive results; more stimulating than ashwagandha and better for morning flatness.
🧬 Eleuthero
Improves stress tolerance and endurance in trials.
🧬 Panax Ginseng
Meta-analysis supports reduced fatigue, including in cancer-related fatigue.
🧬 Cordyceps
Improves exercise capacity and reduces fatigue in small trials, with a mitochondrial mechanism proposed.
🧬 Schisandra
Traditional adaptogen with animal data on stress-response normalisation and hepatoprotection.
🧬 Holy Basil (Tulsi)
Cortisol and glucose regulation together.
🧬 Phosphatidylserine
Blunts the cortisol response to acute stress; useful for the evening spike.
🧬 Cortisol Support
An adaptogen blend aimed at the cortisol curve rather than at the adrenal gland. The distinction matters — the rhythm is usually what is disordered, not the output.
🧬 Adrenal Cortex
Glandular extract. Evidence is essentially absent and the underlying diagnosis is not recognised — worth saying plainly rather than selling around.
🧬 Vitamin B5
Pantothenic acid is a precursor to coenzyme A, required for steroid synthesis. The mechanism is real; the fatigue evidence is not.
🧬 Vitamin C
Concentrated in the adrenal cortex at some of the highest tissue levels in the body, and depleted by acute stress.
🧬 Magnesium
Depleted by chronic stress and required for HPA regulation.
💉 Selank
Anxiolysis without sedation, where the fatigue is driven by sustained arousal.
💉 Bromantane
An actoprotector — raises dopamine synthesis rather than releasing stores, so no depletion crash. Developed specifically for fatigue under load, and used clinically in Russia for asthenia.
🧬 Sulbutiamine
Trialled specifically for asthenia — fatigue with a mental rather than muscular character.

Frequently asked questions
'Adrenal fatigue' is not a diagnosis and the glands rarely fail. What is real is a flattened cortisol curve — low morning, high evening — which produces exactly the tired-but-wired pattern people describe. It is measurable with a four-point salivary test.
16 options are mapped to this pathway in the Vault, including Ashwagandha, Rhodiola, Eleuthero, Panax Ginseng. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 10 carry clinical validation and 6 are mechanistic predictions.
The rhythm is the diagnosis, not the level. Worth being blunt: 'adrenal fatigue' is not a recognised condition and the glands rarely fail — but a flattened cortisol curve is real, measurable and treatable. The markers worth checking are Cortisol (AM), DHEA-S, ACTH (Adrenocorticotropic Hormone), Aldosterone.
Unproven is not the same as ineffective. Of the 16 options on this pathway, 10 have clinical validation and 6 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
