Your Adrenal Hormone Reservoir
DHEA-S is the most abundant steroid hormone in your body—the raw material your adrenals use to make testosterone and estrogen. It peaks in your 20s and declines steadily. By 70, you're running on 10-20% of your peak supply. It's the best single marker of adrenal androgen output.
What is DHEA-S?
DHEA-S is produced almost exclusively by adrenal glands. The sulfated form is stable (no diurnal variation) with a long half-life. It peaks at 20-25 and declines ~2-3% per year. Serves as precursor for peripheral sex steroid production.
↑ What High DHEA-S Means
Adrenal overproduction. In women: causes androgen excess (acne, hirsutism, hair loss). Investigate PCOS, congenital adrenal hyperplasia, or adrenal tumors.
Common symptoms:
Women: acne, hirsutism, hair loss, irregular periods · Men: usually asymptomatic · Children: early puberty (concerning)
↓ What Low DHEA-S Means
Adrenal output declining. From aging, chronic stress, adrenal insufficiency, or chronic illness. Correlates with fatigue, low libido, reduced sense of wellbeing.
Common symptoms:
Fatigue and low energy · Low libido · Depressed mood · Dry skin and hair · Reduced sense of wellbeing · Weakened immunity
Why It Matters
When normal:
Precursor to testosterone and estrogen
Best marker of adrenal androgen function
Correlates with vitality and wellbeing
Immune function support
Risks if abnormal:
High in women: PCOS, virilization, possible adrenal pathology
Very high: investigate adrenal tumor
Low: adrenal insufficiency, reduced wellbeing
What Can Cause Abnormal Levels?
Aging (low)
60% likelyDHEA-S peaks at 20-25 and declines 2-3% per year ("adrenopause").
PCOS (high in women)
50% likelyAdrenal androgen excess contributes to PCOS in 20-30% of cases.
Chronic Stress
Prolonged cortisol demand may eventually exhaust DHEA-S production.
Adrenal Insufficiency
Addison's disease or chronic corticosteroid use suppresses DHEA-S.
What You Can Do
Stress management and adequate sleep
Impact: Supports healthy adrenal function \u00B7 Timeline: 4-8 weeks
Regular moderate exercise (avoid overtraining)
Impact: Supports adrenal output \u00B7 Timeline: 4-8 weeks
If lifestyle changes aren't enough:
DHEA supplement: 25-50mg daily (men), 5-25mg daily (women)
Impact: Directly restores levels. Women need lower doses. \u00B7 Timeline: 4-8 weeks
Monitor testosterone and estrogen when supplementing
Impact: DHEA converts to sex hormones—can cause side effects \u00B7 Timeline: Ongoing
Recommended retest: 3-6 months
