Quick answer
DHEA-S is a precursor hormone made by the adrenal glands. It declines naturally with age. High values can point to adrenal overactivity; low values are common with aging, stress, or adrenal insufficiency.
What is DHEA-S?
Dehydroepiandrosterone sulfate (DHEA-S) is the most abundant steroid in the blood and a building block for other hormones, including testosterone and estrogen. The adrenal glands produce it in a pattern that peaks in youth and falls steadily with age. Its main value in testing is as a window on adrenal output and, in some cases, as a supplement target — though clinical use is still debated.
Typical reference interval: DHEA-S falls with age and differs by sex: healthy young adults commonly measure roughly 100–450 mcg/dL (women slightly lower than men), declining decade by decade. Many labs publish age- and sex-specific ranges — use those, not a generic number.. Laboratories differ — the interval printed on YOUR report always governs.
If your DHEA-S is high
Common reasons DHEA-S runs above the reference interval:
- Adrenal overactivity — tumors or overactive adrenal tissue raise DHEA-S production
- Polycystic ovary syndrome — DHEA-S and related androgens can run high in some women
- DHEA supplements — over-the-counter DHEA directly raises measured levels
- Recent stress surge — ACTH-driven adrenal output can transiently increase it
If your DHEA-S is low
Common reasons DHEA-S runs below the reference interval:
- Normal aging — the single most common cause — DHEA-S declines steadily after the twenties
- Adrenal insufficiency — a failing adrenal gland produces less DHEA-S along with less cortisol
- Chronic illness or high stress — prolonged cortisol demand can shift adrenal output patterns
- Certain medications — steroid therapy suppresses adrenal production
Symptoms worth knowing
DHEA-S itself has no symptoms — it is a background hormone. People who ask about it usually notice aging-related changes (energy, mood, strength) and wonder if low levels explain them; the medical community is still studying how much DHEA-S actually drives those feelings.

Frequently asked questions about DHEA-S results
My DHEA-S is low — do I need a supplement?
Not automatically. Low DHEA-S is the default state of aging and by itself is not a proven disease. If you have fatigue or other symptoms, a clinician looks at the whole hormone picture before recommending supplements — self-supplementing can raise levels beyond what is safe.
Why does my doctor test DHEA-S and cortisol together?
Both come from the same adrenal gland. Cortisol shows current stress-axis output; DHEA-S shows the longer backdrop. Together they reveal whether the adrenal gland is overactive, underactive, or simply aging — one number alone cannot answer that.
