Quick answer: DHEA is a hormone made mainly by the adrenal glands. Its sulfated form, DHEA-S, usually rises around puberty, peaks in early adulthood, and gradually declines with age. This change is common and does not automatically mean something is wrong or that a DHEA supplement is needed. If you have symptoms or an unexpected test result, a clinician can interpret it alongside your age, medical history, medications, and other relevant tests.
It is easy to see why DHEA gets attention. It is often discussed alongside energy, libido, menopause, and aging. But a lower DHEA level is not automatically a problem to fix.
DHEA levels normally change across the lifespan. A number that is lower than it was in your 20s may still be expected for your current age. Symptoms such as fatigue, sleep changes, low mood, low libido, or body-composition changes can also have many possible causes.
The most useful approach is to understand what DHEA is, why it declines, what testing can and cannot tell you, and when it is worth speaking with a healthcare professional.
What is DHEA?
DHEA stands for dehydroepiandrosterone. It is a steroid hormone made mainly by the adrenal glands, which sit above the kidneys. Smaller amounts are also made in the ovaries and testes.
DHEA is sometimes called a precursor hormone because the body can use it to make other hormones, including testosterone and estrogen. The amount converted and its effects can differ by age, sex, tissue, health status, and medication use.
A blood test commonly measures DHEA-S, or dehydroepiandrosterone sulfate. DHEA-S is a sulfated form of DHEA that circulates at higher levels in the bloodstream and is often used to assess adrenal androgen production.
Why DHEA levels change with age
DHEA-S usually rises around puberty, reaches its highest range in early adulthood, and then gradually declines over time. This pattern occurs in both women and men.
Researchers may refer to this age-related change as “adrenopause.” The term does not mean the adrenal glands suddenly stop working. It describes a gradual reduction in DHEA and DHEA-S production as people get older.
| Life stage | Typical DHEA-S pattern | What to remember |
|---|---|---|
| Childhood | Levels are relatively low | Levels naturally change as the adrenal glands mature. |
| Puberty and early adulthood | Levels rise and generally reach their highest range | Reference ranges vary by age, sex, laboratory, and test method. |
| Midlife and later adulthood | Levels gradually decline | A lower result can be expected with age and is not a diagnosis by itself. |
| Any age with concerning symptoms | Results may require additional evaluation | A clinician interprets DHEA-S with symptoms, history, and other tests. |
Age is not the only factor that can affect DHEA-S. Severe illness, adrenal conditions, pituitary conditions, some medications, and other hormone-related concerns can influence results. This is why an individual test result should be interpreted in context—not compared with a single “optimal” number found online.
What DHEA does, and what we still do not know
DHEA and DHEA-S are part of the body’s broader hormone system. Because DHEA can be converted into other sex hormones, it has been studied in relation to sexual function, mood, bone health, skin, body composition, and aging.
But an association does not prove that low DHEA causes a symptom, or that raising DHEA will correct it. DHEA levels decline alongside many other age-related changes.
In a two-year study of older adults, DHEA supplementation increased DHEA-S levels but did not provide clinically meaningful improvements in physical performance, body composition, insulin sensitivity, or quality of life. This is an important reminder that a higher lab value is not automatically the same as a better health outcome.
Does a low DHEA-S result mean you need a supplement?
Not necessarily. DHEA-S results are assessed using age- and sex-specific reference ranges. A level that is lower later in adulthood may be normal for that stage of life.
A clinician may use a DHEA-S test as one part of evaluating adrenal-gland function, symptoms of excess androgen activity, or certain ovarian, testicular, puberty, or hormone-related concerns. A test does not diagnose a condition on its own.
Low DHEA-S can occur with normal aging. It may also occur in some medical conditions, including adrenal insufficiency or pituitary disorders. These conditions need appropriate medical evaluation and should not be self-treated with an over-the-counter hormone product.
Symptoms that should not be self-diagnosed
It is common to find online lists that connect fatigue, low libido, weight changes, sleep problems, and mood changes to “low DHEA.” These symptoms are real, but they are not specific to DHEA.
They can also be related to menopause transition, thyroid conditions, iron deficiency, anemia, stress, depression, anxiety, sleep problems, medication side effects, chronic health conditions, or changes in activity and nutrition.
A symptom checklist cannot diagnose a hormone issue. If a symptom is persistent, severe, new, or affecting your daily life, a clinician can help identify the cause and appropriate next steps.
Natural ways to support overall health
There is no proven lifestyle method that reliably restores DHEA-S to a youthful level or reverses aging. However, foundational health habits can support energy, mood, muscle function, bone health, metabolism, and resilience.
| Supportive habit | Why it matters |
|---|---|
| Prioritize consistent sleep | Poor sleep can affect energy, mood, appetite regulation, and daily function. |
| Move regularly | Aerobic activity and strength training support cardiovascular, bone, and muscle health. |
| Eat enough protein and fiber | Adequate nutrition supports muscle maintenance, digestion, and metabolic health. |
| Manage chronic stress | Stress-management practices can support sleep, mood, and well-being. |
| Limit alcohol and avoid tobacco | These choices support whole-body health and may improve sleep and energy. |
| Address health concerns early | Treating anemia, thyroid disease, sleep apnea, mood symptoms, or menopause concerns is more useful than chasing one hormone number. |
These habits do not promise to raise DHEA. They are practical ways to support the areas of health that people often hope an anti-aging supplement will improve.
What to know about DHEA supplements
DHEA supplements are hormone supplements, not simple vitamins. They can affect androgen and estrogen pathways and may cause steroid-like effects.
Potential effects in women may include oily skin, acne, and unwanted hair growth. DHEA may also be unsuitable for people with certain medical conditions or those taking specific medications.
A DHEA supplement can increase a measured DHEA-S level. That does not mean it will improve energy, strength, body composition, sleep, cognition, or quality of life. DHEA should not be used as a general anti-aging treatment.
When to speak with a clinician
Talk with a qualified healthcare professional before using DHEA if you:
- Are pregnant, breastfeeding, trying to conceive, or may be pregnant.
- Have a history of breast, ovarian, uterine, prostate, or another hormone-sensitive cancer.
- Have endometriosis, PCOS, unexplained vaginal bleeding, or another hormone-related condition.
- Have liver disease, high cholesterol, diabetes, heart disease, or a mood disorder.
- Use hormone therapy, hormonal birth control, fertility medication, cancer treatment, antidepressants, antipsychotics, blood thinners, or other prescription medications.
- Have new or persistent symptoms that could be related to an adrenal, thyroid, reproductive, or other medical concern.
Important: Mayo Clinic advises against DHEA in pregnancy and while breastfeeding. It also notes potential concerns involving hormone-sensitive cancers, HDL cholesterol, mood disorders, and medication interactions.
When to seek medical care
Make an appointment with a clinician if you have:
- Persistent fatigue, unexplained weight loss, dizziness, nausea, vomiting, dehydration, or salt cravings.
- New excess facial or body hair, deepening of the voice, severe acne, or rapid hair loss.
- New menstrual irregularities, very heavy bleeding, bleeding after menopause, or pelvic pain.
- A sudden or significant change in mood, sleep, libido, or daily function.
- Questions about an abnormal hormone test result.
Seek urgent medical care for severe weakness, fainting, confusion, chest pain, or trouble breathing.
Frequently asked questions
At what age does DHEA start to decline?
DHEA-S generally reaches its highest range in early adulthood and then gradually declines with age. The timing and rate vary between people. Clinicians use age- and sex-specific reference ranges because a lower level later in life may be normal.
Can I increase DHEA naturally?
No lifestyle practice has been proven to reliably restore DHEA-S to youthful levels. Sleep, movement, adequate nutrition, stress management, and treatment of underlying health conditions can support overall well-being, but should not be presented as guaranteed DHEA-raising strategies.
Is DHEA a proven anti-aging supplement?
No. Research does not support DHEA as a proven anti-aging treatment. In a two-year study of older adults, DHEA raised DHEA-S levels but did not lead to clinically meaningful improvements in physical performance, body composition, insulin sensitivity, or quality of life.
Can DHEA help with menopause symptoms?
Some DHEA-based treatments are studied in specific clinical settings, including certain vaginal symptoms after menopause. An oral over-the-counter DHEA supplement is not a general treatment for menopause. Speak with a clinician about hot flashes, vaginal dryness, painful sex, sleep disruption, or mood changes.
Should women take DHEA for low libido or fatigue?
Not without clinical guidance. Low libido and fatigue can have many causes, including sleep problems, stress, mood changes, medication effects, anemia, thyroid conditions, relationship factors, and menopause. DHEA may be inappropriate or unsafe depending on your health history and medications.
What is the difference between DHEA and DHEA-S?
DHEA is the hormone itself. DHEA-S is its sulfated form, which circulates at higher levels in the blood and is commonly measured in laboratory testing. A clinician may use DHEA-S to help assess adrenal androgen production.
