DHEA-sulfate
HormonesAlso known as: DHEA-S, DHEAS, dehydroepiandrosterone sulfate
A hormone produced primarily by the adrenal glands that serves as a precursor for testosterone and estrogen.
Levels naturally peak in early adulthood and decline with age. Some research suggests maintaining healthy DHEA-S levels may support energy, immune function, and stress resilience, though evidence for supplementation remains mixed.
Why this matters
DHEA-S is considered a marker of adrenal function and overall vitality. Optimal levels vary by age and sex. Low levels may contribute to fatigue, decreased muscle mass, low libido, depression, and weakened immune function. High levels can indicate conditions such as adrenal tumors or polycystic ovary syndrome (PCOS).
Monitoring DHEA-S provides insight into adrenal health and hormonal balance, while lifestyle factors including stress management, regular exercise, balanced nutrition, and adequate sleep support healthy hormone levels.
How this connects to other biomarkers
- DHEA-Sulfate is the dominant adrenal androgen and a sensitive marker of adrenal-cortex activity.
- Low DHEA-S with low morning Cortisol and elevated ACTH suggests adrenal failure (Addison's disease); very low DHEA-S in young adults can flag adrenal exhaustion or pituitary disease.
- Elevated DHEA-S in women with hirsutism (excess body hair) and high Testosteron, total points to an adrenal source of androgen excess (PCOS — polycystic ovary syndrome, congenital adrenal hyperplasia, or an adrenal tumor).
How often should I test DHEA-sulfate?
Most adults benefit from yearly DHEA-sulfate testing from their 30s onwards as part of an adrenal hormone panel. If you're supplementing DHEA, retest at 6 to 12 weeks after starting or changing the dose.
At baseline / for screening: Once every 12 months from age 30 as part of an adrenal or hormone panel.
When monitoring an intervention or change: Retest 6 to 12 weeks after starting or adjusting DHEA supplementation. DHEA-sulfate has a long half-life and doesn't fluctuate much across the day, so timing of the draw isn't critical.
Note: DHEA-S has a long half-life and doesn't fluctuate much across the day, making single readings reliable. After starting DHEA supplementation, wait 6 to 12 weeks for a steady-state value before reading as your new baseline.
