Low DHEA Levels: Symptoms, Testing, and Treatment Options

What Is DHEA?

DHEA, or dehydroepiandrosterone, is a hormone produced primarily by the adrenal glands. It serves as a precursor hormone, meaning it can be converted into other key hormones, including testosterone and estrogen, in both men and women.

DHEA levels naturally peak in early adulthood and gradually decline with age. By midlife, many individuals have significantly lower levels than they did in their 20s, even in the absence of overt disease. Chronic stress, illness, poor sleep, and adrenal strain can further suppress DHEA production.

1. Why DHEA Matters

DHEA plays a supporting role across multiple physiologic systems. Research suggests that appropriate DHEA levels may contribute to:

• Maintenance of lean muscle mass
• Support for mood and emotional resilience
• Libido and sexual function
• Cognitive performance and mental clarity
• Immune system regulation

Because DHEA influences downstream sex hormones, low levels can have wide-ranging effects that are often subtle but cumulative over time.

2. What Causes Low DHEA?

Low DHEA-S levels can result from a range of physiological and lifestyle factors. The most common include:

• Age-related adrenal decline the most common cause; production falls steadily from the mid-20s onward
• Chronic psychological or physical stress diverts adrenal resources toward cortisol production at the expense of DHEA
• Poor or insufficient sleep disrupts the circadian rhythms that regulate adrenal hormone output
• Adrenal insufficiency or dysfunction (including Addison’s disease) where the adrenal glands do not produce adequate hormones
• Severe or prolonged illness suppresses adrenal androgen production
• Anorexia nervosa and significant caloric restriction associated with marked reductions in DHEA-S
• Certain medications including corticosteroids (such as prednisone), which suppress adrenal function with long-term use
• Hyperprolactinemia (elevated prolactin levels) which can suppress adrenal androgen production

Note: Low DHEA-S does not always cause symptoms. Clinical significance depends on the degree of decline, the patient’s age, sex, and overall hormonal context.

3. Common Symptoms of Low DHEA

Low DHEA does not present the same way in everyone, but commonly reported symptoms include:

Symptoms of Low DHEA in Females

Women are more sensitive to fluctuations in DHEA levels than men, in part because DHEA is a primary androgen source for women, particularly after menopause when ovarian hormone production declines. Female-specific symptoms of low DHEA-S include:

• Vaginal dryness, irritation, or painful intercourse (dyspareunia) particularly during and after menopause, associated with genitourinary syndrome of menopause (GSM)
• Irregular or absent menstrual cycles in premenopausal women
• Reduced sexual desire and difficulty with arousal
• Worsening mood, low motivation, or symptoms consistent with depression
• Thinning hair or diffuse hair loss
• Accelerated loss of bone density, increasing risk of osteopenia or osteoporosis

Fatigue and reduced vitality, particularly during the perimenopausal transition

Symptoms of Low DHEA in Males

In men, DHEA serves as a precursor to testosterone and plays a role in maintaining androgen tone as testosterone levels naturally decline with age. The Massachusetts Male Aging Study identified DHEA-S as one of the few hormones significantly correlated with erectile dysfunction among the 17 hormones it examined. Male-specific symptoms of low DHEA-S include:

• Reduced libido and diminished sexual desire
• Erectile dysfunction (ED)  low DHEA-S is associated with ED independent of testosterone levels in some research
• Declining energy and persistent fatigue, sometimes attributed to andropause
• Loss of muscle mass and reduced physical strength
• Increased abdominal fat or unfavorable changes in body composition
• Low mood, reduced motivation, or symptoms consistent with depression
• Difficulty with concentration and memory

4. What Is Considered Low DHEA?

DHEA levels are evaluated via a blood test measuring DHEA-S (the sulfated, stable form). A result below the lower bound for your age and sex group is generally considered low. The table below reflects reference ranges used by major academic medical centers including Mount Sinai and UCSF:

Reference ranges may vary slightly between laboratories. Results should always be interpreted in clinical context by a qualified healthcare provider. Values sourced from Mount Sinai and UCSF Health reference data.

A result within range does not rule out functionally suboptimal levels for an individual, particularly in younger adults whose levels may have declined significantly from a personal peak. Symptom burden should always be considered alongside lab values.

5. How DHEA Is Tested

Blood testing usually measures DHEA-S — the sulfated form of DHEA — because it remains stable throughout the day, unlike DHEA which fluctuates with diurnal rhythms. Testing provides objective data that helps determine whether levels are appropriate for age and sex. One common question patients raise is how much does DHEA testing cost; the answer depends on whether the test is ordered alone or bundled into a broader hormone panel, which your provider can clarify during a consultation.

Importantly, symptoms alone are not sufficient to guide supplementation. Lab testing allows for individualized, evidence-guided decisions.

6. When DHEA Supplementation May Be Considered

DHEA supplementation is not appropriate for everyone. When used, it should be guided by laboratory data and clinical context. In individuals with confirmed low levels and compatible symptoms, carefully dosed supplementation may offer symptomatic support for energy, mood, libido, and hormonal balance in select patients.

Because DHEA can convert into other hormones, inappropriate dosing or unsupervised use can lead to unwanted side effects. Medical guidance is essential. For anyone wondering how to treat low DHEA levels safely, the starting point is always confirmed lab work paired with a provider who can customize DHEA deficiency treatment to your specific hormonal profile.

7. The RMRM Approach

DHEA is a small hormone with an outsized impact on how many people feel as they age. If fatigue, mood changes, or low libido have been persistent despite good sleep, nutrition, and exercise, evaluating DHEA levels may provide useful insight.

At Rocky Mountain Regenerative Medicine, hormone evaluation is always individualized and guided by data — not guesswork.  If your evaluation points to a broader hormonal shift rather than DHEA alone, your provider may discuss this alongside RMRM’s hormone therapy program as part of your personalized plan.
