Hypoadrenalism

Hypoadrenalism — also known as adrenal insufficiency — is when the adrenal glands don’t make enough cortisol due to adrenal gland damage (primary hypoadrenalism) or insufficient production of adrenocorticotropic hormone (ACTH) by the pituitary gland (secondary hypoadrenalism).

Hypoadrenalism — also known as adrenal insufficiency — is when the adrenal glands don’t make enough cortisol due to adrenal gland damage (primary hypoadrenalism) or insufficient production of adrenocorticotropic hormone (ACTH) by the pituitary gland (secondary hypoadrenalism).

Evidence-Based Protocol

Supplement stack ranked by research quality

Limited Evidence

Primary Stack (Tier 1)

500-1000mg daily in divided doses

Adrenal glands have highest vitamin C concentration; essential for cortisol and catecholamine synthesis

6 studies | 300 participants

Essential for synthesis of coenzyme A and steroid hormones in adrenal glands

5 studies | 200 participants

Supporting Stack (Tier 2)

25-50mg daily (women); 50-100mg daily (men) - under medical supervision

Adrenal androgen often deficient in adrenal insufficiency; may improve quality of life

12 studies | 600 participants
200-400mg standardized extract daily (short-term only; medical supervision required)

Inhibits cortisol breakdown (11β-HSD); may extend cortisol action (use with caution)

6 studies | 200 participants
300-400mg daily

Often depleted in adrenal insufficiency; supports energy production and stress response

5 studies | 200 participants
50-100mg daily

Supports neurotransmitter synthesis and adrenal function

4 studies | 150 participants
Liberal salt intake (3-4g sodium daily) if mineralocorticoid-deficient

Primary adrenal insufficiency causes salt wasting; adequate sodium intake critical

8 studies | 400 participants
Rhodiola: 200-400mg daily; Eleuthero: 300-400mg daily

May support HPA axis adaptation to stress; adjunctive support only

6 studies | 300 participants

How It Works

Hypoadrenalism (adrenal insufficiency) occurs when the adrenal glands don't produce enough hormones, particularly cortisol. Primary adrenal insufficiency (Addison's disease) involves damage to the adrenal glands themselves, while secondary adrenal insufficiency results from pituitary problems affecting ACTH (the hormone that stimulates the adrenals). Symptoms include severe fatigue, weight loss, low blood pressure, dizziness, salt cravings, hyperpigmentation (in primary), nausea, and weakness. Without treatment, adrenal crisis can be life-threatening.

CRITICAL: Adrenal insufficiency is a serious medical condition requiring hormone replacement therapy (hydrocortisone/cortisol replacement, and fludrocortisone for primary AI). This is NOT optional - it is life-sustaining treatment. Patients must wear medical alert identification, understand sick-day rules (increasing dose during illness/stress), carry emergency injection kits, and know signs of adrenal crisis. NO supplement can replace cortisol. These supplements support overall adrenal health but are ADJUNCTIVE to medical treatment. Never adjust steroid doses based on supplements or stop medication.

* Vitamin C is found in very high concentrations in the adrenal glands and is essential for synthesizing cortisol and catecholamines. Adequate intake supports remaining adrenal function.

* Vitamin B5 (Pantothenic Acid) is critical for producing coenzyme A, which is necessary for steroid hormone synthesis.

* DHEA is an adrenal androgen that is often deficient in adrenal insufficiency but not replaced by standard therapy. Studies show DHEA replacement can improve energy, mood, and quality of life, especially in women. Requires medical supervision.

* Licorice Root inhibits the enzyme that breaks down cortisol, potentially extending its effects. Use with extreme caution and only under medical supervision - can cause hypertension and hypokalemia.

* Magnesium supports energy production and is often depleted during stress.

* Sodium/Salt - Primary adrenal insufficiency causes aldosterone deficiency and salt wasting. Liberal salt intake is important, especially in hot weather or with exercise.

* Adaptogenic herbs may provide additional stress support but cannot replace hormone therapy.

Expected timeline: Hormone replacement provides benefit within days. DHEA effects may take 3-6 months to fully assess. Supplements support ongoing wellness.

Stress (particularly distress) is excessive stimulation of the body's resources that eventually leads to negative symptoms such as fatigue or depression. Several supplements, such as adaptogens, are thought to reduce the development of stress.
