DHEA-Sulfate (DHEA-S)
Cortisol swings with the clock and with stress. DHEA-sulfate barely moves, which is exactly why your doctor draws it. Here is what the number actually says.
Part of the Hormone Panel — see all 21 values together, including 17-Hydroxyprogesterone, Aldosterone, Androstenedione.
DHEA-sulfate is the one adrenal hormone you can draw at any hour of the day and still trust the number. Its loud neighbor, cortisol, surges at dawn, drifts down by night, and spikes whenever you are stressed, so the time stamped on the tube changes the result. DHEA-S barely moves. If cortisol is the burner that roars up under pressure and flares with the daily rhythm, DHEA-S is the pilot light underneath it: a small, constant flame the adrenal glands keep lit around the clock.
That steadiness is not an accident of biology so much as a quirk of chemistry. Made mainly in the zona reticularis of the adrenal glands, DHEA-S is, per MedlinePlus, the most abundant circulating steroid hormone in the body and a precursor the body converts into androgens and estrogens. It is the sulfated form, with a long half-life and slow renal clearance measured in many hours rather than minutes. Research summarized in the saliva-timing literature puts that half-life in the range of ten to sixteen hours, which is precisely why labs measure DHEA-S instead of plain DHEA: the sulfated version holds still long enough to read. Because DHEA-S sits downstream of pregnenolone, the first steroid the body builds from cholesterol, it is the directly measured marker clinicians actually rely on rather than the precursor at the top of the chain.
So when a hormone panel reports DHEA-S, it is usually there to answer one question: how much androgen precursor are the adrenal glands putting out? MedlinePlus describes it as a marker of adrenal function, and it is often run alongside testosterone and estrogen so a clinician can see where excess or deficient hormone is coming from. Because both are adrenal-leaning androgens, DHEA-S is frequently paired with androstenedione to help localize whether an androgen excess is coming from the adrenal glands. One honest caveat: steady is not the same as frozen. Some studies do find readings run a little higher in the morning than the evening, so the right way to think about DHEA-S is stable, not perfectly flat.
How a DHEA-S result is read
mcg/dLCan reflect adrenal insufficiency or Addison disease, a pituitary problem, or glucocorticoid (steroid) medication, per MedlinePlus. A level near 18 sits below most adult bands and usually prompts a look at ACTH and cortisol.
A 250 in a younger woman, for instance, sits comfortably mid-band. Levels also fall steadily with age, so a number that looks low against a twenty-something range can be entirely normal later in life.
A reading near 400 in an adult woman runs at or above the usual range, and paired with acne or facial hair it points toward a hormonal cause worth investigating.
A man's DHEA-S of 600 or over 700 climbs past the young-adult ceiling near 510, the kind of jump that prompts a search for an adrenal source.
Ranges shift with both age and sex, so the same number is read very differently from one person to the next, and they vary by lab as well. There is no single normal cutoff. MedlinePlus publishes age-banded reference figures that show how far the target drifts across a lifetime:
| Age | Female (mcg/dL) | Male (mcg/dL) |
|---|---|---|
| 18-29 | 45-320 | 110-510 |
| 30-39 | 40-325 | 110-370 |
| 40-49 | 25-220 | 45-345 |
| 50-59 | 15-170 | 25-240 |
| 60+ | under 145 | under 204 |
The drift in that table is the point. A DHEA-S of 25 can sit inside the normal band for a woman in her fifties while reading as distinctly low for a woman in her twenties. The number means nothing until you place it against the right age and sex. Like other hormones that drift with age, DHEA-S is best read against age-specific expectations, the same trap that makes a "low" IGF-1 in an older adult so easy to misread.
What does a high DHEA-S mean?
A high DHEA-S says the adrenal glands are pushing out more androgen precursor than expected, and the job is to find why. In women the question often arrives with acne, unwanted facial or body hair, or irregular cycles, which is the cluster many people search for as the "PCOS hormone." MedlinePlus names a handful of causes worth ruling in or out.
What can push DHEA-S high
-
Polycystic ovary syndrome
A common reason for a raised androgen picture in women, often read next to total and free testosterone.
-
Congenital adrenal hyperplasia
An inherited enzyme difference in steroid production that can lift adrenal androgens.
-
Adrenal tumor
A growth in the gland itself, more likely when the elevation is large.
-
Precocious puberty
Early activation of adrenal androgen output in children.
Because DHEA-S comes specifically from the adrenal glands, a high result helps separate an adrenal source of androgen excess from an ovarian or testicular one. When a high DHEA-S points at the adrenal glands as the source of androgen excess, 17-hydroxyprogesterone is usually measured alongside it to check for the enzyme block behind congenital adrenal hyperplasia. That is the quiet value of a stable marker: it gives a clinician a fixed point to triangulate from while the faster hormones are still moving.
What does a low DHEA-S mean?
A low DHEA-S is the reading behind phrases like "my DHEA is tanked" and the worry about low energy and no libido. The first thing to settle is whether the number is actually low for the person's age, since DHEA-S declines naturally over the decades. Past that, MedlinePlus links a genuinely low result to adrenal insufficiency or Addison disease, to hypopituitarism where the pituitary fails to drive the adrenal glands, and to glucocorticoid medication, which suppresses adrenal output. This is where reading the level alongside ACTH and cortisol earns its place, because the combination tells a clinician whether the problem sits in the adrenal gland or upstream in the pituitary.
The supplement question
Here is where DHEA gets sold something it cannot deliver. Because the hormone falls with age, the supplement aisle frames that decline as a deficiency to fix, promising restored mood, energy, well-being, and a turned-back clock. The evidence does not cooperate. The MSD Manual states plainly that the medicinal claims of DHEA have not been fully supported, and the NIH Office of Dietary Supplements rates the case for general anti-aging or athletic benefit as limited.
Raising the number also is not free. The same sources document real downsides, which is why this belongs in a clinic, not a checkout line.
Before you reach for a DHEA supplement
-
1
Start with your doctor
A falling DHEA-S is usually ordinary aging, not a deficiency, so the first step is asking whether there is any reason to treat the number at all.
-
2
Know the documented risks
The MSD Manual lists gynecomastia in men, hirsutism and acne in women, mood changes, lowered HDL, raised triglycerides, and worsened PCOS among the reported effects.
-
3
Take cancer history seriously
Because DHEA converts to androgens and estrogens, the MSD Manual flags possible stimulation of hormone-sensitive prostate, breast, and liver cancers as a concern to weigh with a clinician.
Reading DHEA-S in context
DHEA-S is rarely the whole story on its own. It works best as the steady anchor of a hormone workup, which is why it usually appears as part of the hormone panel rather than in isolation, drawn next to cortisol, testosterone, and the pituitary signal. If you want the fuller picture of how these results read together, the guide to reading a hormone panel walks through the combinations. And because DHEA-S moves so slowly, a single value matters less than its drift over the years against your own age band: the pilot light dimming gradually with time is expected, while a sharp change is the thing worth a conversation.

Cortisol runs on a daily timetable, peaking around the moment you wake and thinning out by midnight. Read without the clock beside it, the number on your report can look alarming and mean almost nothing.
ACTH is the pituitary's order to the adrenal glands to make cortisol. On its own the number means little. Paired with a cortisol that has already come back wrong, it points to where the fault sits.
Total testosterone counts every molecule of the hormone in your blood, but most of it is locked away and unavailable. That gap is why a normal result and real symptoms can sit on the same report.
Free testosterone is the sliver of the hormone your tissues can actually reach. When total testosterone looks fine but you don't, this is usually the number worth checking, and how it was measured changes whether you can trust it.
Growth hormone pulses through the day in bursts no single blood draw can catch. IGF-1 is the steady downstream level clinicians read instead, and reading it wrong cuts both ways.
Most androgen tests measure a finished hormone. This one measures a half-built part still on the bench, and that is exactly what makes it worth drawing.
17-OHP barely does anything on its own. Its whole value is where it sits: one step before the enzyme that's missing in most congenital adrenal hyperplasia.
The supplement aisle calls it the mother hormone and promises sharper memory and slower aging. The single human trial that tested those claims found nothing.
