DHEA - Dehydroepiandrosterone
DHEA (dehydroepiandrosterone) is the most abundant steroid hormone in the human body, produced primarily by the adrenal glands with smaller amounts made in the ovaries, testes and brain. It functions as a precursor to both testosterone and estrogen, which is why DHEA levels directly influence energy, libido, body composition and mood. DHEA-S (the sulfated form) peaks in early adulthood and declines by roughly 10% per decade after age 25. Testing DHEA sulfate through a simple blood test can reveal whether levels are too low or too high, both of which produce distinct symptoms. Optimizing DHEA through targeted supplementation, lifestyle changes and adrenal support can restore vitality, improve hormonal balance and reduce the metabolic consequences of aging.
What is DHEA?
DHEA stands for dehydroepiandrosterone. It is the most abundant steroid hormone in the human body and is produced primarily by the adrenal glands that sit on top of each kidney. Smaller amounts are also made in the ovaries, testes and brain. Unlike hormones that act on a single target, DHEA functions as a precursor hormone, meaning your body converts it into other hormones including testosterone and estrogen depending on what is needed.
The adrenal glands produce DHEA in the zona reticularis layer under the control of adrenocorticotropic hormone (ACTH) from the pituitary gland. Once released into the bloodstream, most DHEA is converted into its sulfated form called DHEA-S or DHEA sulfate. This conversion happens in the adrenal glands and liver. Because DHEA-S has a much longer half-life and does not fluctuate throughout the day like unconjugated DHEA, it serves as a stable reservoir that your body can draw from when it needs to produce sex hormones in peripheral tissues.
DHEA levels follow a predictable pattern across the lifespan. Levels are high in the fetus, drop shortly after birth and remain low throughout childhood. Production ramps up during puberty and peaks in your mid-20s. After age 25, DHEA and DHEAS decline at a rate of roughly 10% per decade. By age 70 to 80, levels may be only 10% to 20% of what they were at their peak. This gradual decline is sometimes referred to as adrenopause, and it is one reason why symptoms like fatigue, low libido and reduced muscle mass become more common with age.
The ratio of DHEA-S to DHEA in circulation is approximately 250 to 300 times higher for the sulfated form. This is why most lab tests measure DHEA sulfate rather than unconjugated DHEA when evaluating adrenal function and androgen status. Understanding what is DHEA and how it relates to the broader hormone network is the first step in determining whether your levels are contributing to the symptoms you are experiencing.
DHEA Benefits
The benefits of DHEA extend across multiple systems because it functions both as a precursor to testosterone and estrogen and as an active hormone with its own direct effects. According to research published in the Journal of Sexual Medicine, DHEA supports:
- Endothelial function and blood flow
- Insulin sensitivity and glucose metabolism
- Immune function and cellular immunity
- Bone density and body composition
- Cognitive function and neuroprotection
- Mood regulation and stress response
The specific DHEA advantages you experience depend on your age, sex and baseline hormone status. Because DHEA serves as raw material for sex hormones, optimizing levels can improve energy, libido and overall vitality. Testing is an important first step before supplementation.
DHEA Benefits For Women
DHEA for women plays a particularly important role during perimenopause and menopause when ovarian hormone production declines. While the ovaries slow down, the adrenal glands continue producing DHEA, which peripheral tissues convert into estrogen and testosterone as needed.
Vaginal And Sexual Health
Intravaginal DHEA (prasterone) is FDA-approved for treating genitourinary syndrome of menopause. According to research in PMC, DHEA supplement for women improves vaginal dryness, increases lubrication and reduces painful intercourse.
Bone And Skin Health
The hormone DHEA for women supports bone mineral density at key sites including the hip and spine. It also stimulates collagen and sebum production, which may improve skin hydration and reduce visible signs of aging.
Mood And Energy
DHEA benefits for women include improved psychological well-being, reduced fatigue and enhanced libido. These effects are most pronounced in women with documented low levels or those with adrenal insufficiency.
DHEA Benefits for Men
DHEA for men supports testosterone production, body composition and sexual function, particularly as natural hormone levels decline during andropause. While men continue producing testosterone in the testes throughout life, adrenal DHEA contributes to overall androgen status and becomes more relevant with age. DHEA for men supports testosterone production, body composition and sexual function, particularly as natural hormone levels decline during andropause. While men continue producing testosterone in the testes throughout life, adrenal DHEA contributes to overall androgen status and becomes more relevant with age.
When Testing Matters
Because DHEA for men works best when there is an actual deficit to correct, testing DHEA-S levels before supplementation is essential. This ensures you are addressing a real imbalance rather than adding hormones your body does not need.
Signs of Low DHEA Levels
As DHEA declines naturally with age, many people develop symptoms that overlap with general aging but may actually reflect a correctable hormone deficit. Low DHEA levels are also associated with adrenal insufficiency, chronic stress, severe illness and certain medications like corticosteroids.
Common Symptoms
- Persistent fatigue and low energy
- Decreased libido and sexual dysfunction
- Loss of muscle mass and strength
- Increased abdominal fat
- Low mood, irritability or depression
- Dry skin and reduced skin elasticity
- Joint discomfort
Conditions Linked to Low DHEA
According to MedlinePlus, low DHEA-S levels may indicate:
- Addison disease (primary adrenal insufficiency)
- Hypopituitarism (underactive pituitary gland)
- Chronic fatigue syndrome
- Severe systemic illness or prolonged stress
If you are experiencing several of these symptoms, testing your DHEA sulfate levels can help determine whether low DHEA is a contributing factor or whether other conditions need to be ruled out.
Signs of High DHEA Levels
While low DHEA gets more attention, elevated DHEA can cause significant symptoms, particularly in women. High DHEA signals excess androgen activity and may point to an underlying condition that requires evaluation.
Symptoms in Women
High DHEA sulfate in females often presents with androgenic symptoms including:
- Acne along the jawline, chest and back
- Oily skin and clogged pores
- Excess facial and body hair (hirsutism)
- Thinning hair on the scalp (androgenic alopecia)
- Irregular or missed periods
- Difficulty conceiving
- Deepening voice in severe cases
Symptoms in Men
Men with high DHEA may not notice obvious symptoms since their baseline androgen levels are already higher. In some cases, elevated levels may contribute to acne, oily skin or mood changes.
Conditions Associated with High DHEA
- PCOS (polycystic ovary syndrome) – the most common cause in women
- Congenital adrenal hyperplasia
- Cushing syndrome
- Adrenal tumors (suspected when levels are extremely high or symptoms develop rapidly)
Mild elevations are often idiopathic or stress-related. However, DHEA-S levels above 600 mcg/dL warrant further investigation to rule out an androgen-secreting adrenal tumor.
DHEA Testing: The DHEA Sulfate Blood Test
The most reliable way to assess your DHEA status is through a DHEA sulfate blood test. Providers measure DHEA-S rather than unconjugated DHEA because the sulfated form is far more stable and does not fluctuate throughout the day like other hormones.
What to Expect During DHEA Testing
A DHEA blood test requires a simple blood draw from a vein in your arm. No fasting is required, and the procedure takes less than five minutes. Results are typically available within a few days.
Normal Reference Ranges
According to Mount Sinai, normal DHEAS levels vary significantly by age and sex:
| Age | Women (mcg/dL) | Men (mcg/dL) |
|---|---|---|
| 18-29 | 45-320 | 280-640 |
| 30-39 | 40-325 | 120-520 |
| 40-49 | 30-280 | 95-530 |
| 50+ | 20-200 | 70-310 |
Levels decline steadily after the mid-20s, so interpreting results requires considering your age and symptoms, not just where you fall in the range.
Other Hormones Often Tested Alongside DHEA-S
A DHEA lab test is rarely done in isolation. Your provider may also order:
- Total and free testosterone
- Estradiol
- Cortisol
- LH and FSH
- Thyroid panel (TSH, free T3, free T4)
- Fasting insulin
This broader panel helps identify whether low or high DHEA sulfate is part of a larger hormonal imbalance.
DHEA Supplementation
In the United States, DHEA supplement products are classified as dietary supplements and available over the counter without a prescription. This makes DHEA supplements widely accessible, but it also means quality control varies significantly between brands.
Forms Available
Dietary supplement DHEA comes in several forms:
- Oral capsules and tablets (most common)
- Sublingual tablets (dissolve under the tongue)
- Topical creams and gels
- Micronized powder
Prescription DHEA (prasterone) is FDA-approved as an intravaginal insert for treating vaginal atrophy and painful intercourse in postmenopausal women.0
Typical Dosing
There is no universally agreed-upon dose for DHEA supplements. Most studies use doses ranging from 25 mg to 100 mg daily. Women typically require lower doses (10-25 mg) than men due to greater sensitivity to androgens.
When choosing the best DHEA supplement, look for products that have been third-party tested for purity and potency. Research has shown that many over-the-counter DHEA products do not contain the amount listed on the label.
Medical Supervision Matters
Because DHEA is a hormone that converts into testosterone and estrogen, supplementing without monitoring can lead to unintended side effects. Your provider should check baseline DHEA-S levels before starting and retest periodically to ensure levels stay within a healthy range.
Why Take DHEA at Night
A common question is why take DHEA at night versus morning. The answer depends on individual response. Some providers recommend morning dosing to align with the body’s natural cortisol rhythm, since DHEA is produced by the same adrenal glands that release cortisol upon waking. Others suggest evening dosing if the supplement causes alertness or if the goal is supporting overnight recovery and hormone production.
DHEA Side Effects
Because DHEA converts into testosterone and estrogen, supplementation can produce androgenic or estrogenic effects depending on your body’s conversion pathways. Most DHEA side effects are dose-dependent and reversible when supplementation is reduced or stopped.
Common Side Effects
- Oily skin and acne
- Hair loss on the scalp
- Facial hair growth in women (hirsutism)
- Deepening voice in women
- Mood changes, irritability or agitation
- Decreased HDL (good) cholesterol
Who Should Avoid DHEA
DHEA supplementation is not appropriate for everyone. You should avoid DHEA or use it only under close medical supervision if you have:
- History of hormone-sensitive cancers (breast, ovarian, prostate)
- Liver disease
- Diabetes or blood sugar imbalances
- Mood disorders including bipolar disorder
- PCOS (may worsen androgen excess)
Drug Interactions
- Estrogen and testosterone therapy
- Insulin and diabetes medications
- Antipsychotics and lithium
- Selective serotonin reuptake inhibitors (SSRIs)
- Corticosteroids
Frequently Asked Questions on DHEA
How Do You Treat High DHEA Levels in Females?
Treating high DHEA levels in females starts with identifying the underlying cause. If PCOS is the driver, addressing insulin resistance through diet, exercise and supplements like myo-inositol or berberine often helps lower androgen levels. For adrenal causes, stress management and adaptogen support may be beneficial. In some cases, oral contraceptives or anti-androgen medications like spironolactone are prescribed. Work with your provider to determine why levels are elevated before pursuing treatment.
What Does DHEA Do for Men?
DHEA for men supports testosterone production, body composition, energy and sexual function. As a precursor hormone, DHEA is converted into testosterone in peripheral tissues. Benefits are most noticeable in older men or those with documented low levels and may include improved libido, reduced body fat and increased muscle strength.
Does DHEA Increase Testosterone?
Yes, DHEA can increase testosterone, but the effect varies by sex and baseline hormone status. DHEA supplementation significantly raises testosterone levels, with a greater effect in women than men. Younger men with normal testosterone typically see little to no increase.
How To Treat Low DHEA Levels in Females?
Treating low DHEA in women may involve oral supplementation under medical supervision, typically at doses between 10-25 mg daily. Supporting adrenal health through stress reduction, adequate sleep and adaptogenic herbs can also help. Your provider should monitor DHEA-S levels and watch for androgenic side effects like acne or hair changes.
Can DHEA Cause Weight Gain?
No, DHEA does not typically cause weight gain. In fact, low DHEA is associated with increased abdominal fat.DHEA supplementation in elderly women actually decreased BMI and improved lean body mass. Weight gain concerns are more relevant when DHEA is too low, not too high.
What Is DHEA Sulfate in a Blood Test?
DHEA sulfate is the sulfated form of DHEA measured in a DHEA blood test. Because DHEA-S has a longer half-life and does not fluctuate throughout the day, it provides a more stable and accurate picture of your adrenal androgen status than unconjugated DHEA. The DHEA lab test is used to evaluate adrenal function and investigate symptoms of hormone imbalance.
Does DHEA Cause Hair Loss?
DHEA can contribute to hair loss in individuals who are sensitive to androgens. When DHEA converts to testosterone and then to DHT (dihydrotestosterone), it may trigger androgenic alopecia in genetically predisposed individuals. This side effect is dose-dependent and more common in women. If you notice scalp thinning while taking DHEA, consult your provider about adjusting your dose.
