Dehydroepiandrosterone (DHEA) Supplements: Uses, Health Benefits, Side Effects, and Dosage

4

DHEA is a naturally occurring adrenal hormone that declines steadily with age and serves as a precursor to testosterone and estrogens. As a supplement, it’s promoted for energy, mood, sexual health, fertility, healthy aging, and athletic performance—but the evidence is mixed. Some uses are well supported (for example, prescription intravaginal prasterone 6.5 mg for postmenopausal painful intercourse), while others show small or uncertain benefits (such as depressive symptoms or autoimmune conditions). DHEA can also cause androgenic side effects and interact with hormone-sensitive conditions. This guide explains how DHEA works, where the data are strongest, typical dose ranges used in studies, who should avoid it, and how to discuss safe, individualized use with a clinician.

Top DHEA Highlights at a Glance

  • Intravaginal DHEA (prasterone) 6.5 mg nightly can improve genitourinary syndrome of menopause symptoms.
  • Oral DHEA shows small, low-certainty benefits for depressive symptoms in some trials.
  • Typical study doses: 25–50 mg/day (adrenal insufficiency, general replacement); 25–100 mg/day (varied trials); 6.5 mg intravaginal nightly (prasterone).
  • Possible side effects include acne, oily skin, hair growth, hair loss, and HDL lowering; monitor hormones if used.
  • Avoid if pregnant, trying to conceive without clinician guidance, or with hormone-sensitive cancers (breast, prostate, endometrial).

What is DHEA and how does it work?

Dehydroepiandrosterone (DHEA) is a steroid hormone synthesized primarily by the adrenal glands (with smaller contributions from the gonads and brain). Circulating DHEA is present mostly as the sulfate ester DHEA-S, a stable reservoir with a long half-life. Both DHEA and DHEA-S can be converted within tissues into active androgens (e.g., testosterone, dihydrotestosterone) and estrogens (e.g., estradiol). This local “intracrine” conversion means blood levels don’t always mirror tissue effects—one reason results can vary from person to person.

DHEA production peaks in early adulthood and declines by as much as 70–80% by the seventh decade. Because DHEA is upstream of sex steroids, lower levels with aging prompted interest in supplementation as a way to support libido, mood, bone, skin, and energy. In reality, benefits depend on context: baseline hormone status, dose, formulation, and the clinical outcome targeted.

You’ll see DHEA sold as an over-the-counter dietary supplement (oral tablets/capsules, sublingual lozenges, topical creams). Separately, a prescription intravaginal form of DHEA—prasterone 6.5 mg nightly—is approved for treating moderate-to-severe dyspareunia (painful intercourse) related to postmenopausal vulvovaginal atrophy/genitourinary syndrome of menopause. Major societies list vaginal DHEA among effective options for these symptoms, alongside low-dose vaginal estrogen and ospemifene.

Mechanistically, DHEA may influence:

  • Sex-steroid signaling: tissue-specific conversion to androgens/estrogens that support vaginal epithelium, bone turnover, and libido.
  • Neurosteroid effects: modulation of GABAergic and glutamatergic pathways, stress response, and mood.
  • Immune modulation: small anti-inflammatory effects observed in some autoimmune settings.
  • Metabolism/body composition: inconsistent changes in fat mass, insulin sensitivity, and lipids; effects are sex- and dose-dependent.

Because DHEA can convert to bioactive sex steroids, its potential benefits arrive with trade-offs—particularly androgenic side effects and possible risks in hormone-sensitive conditions. Choosing the right route (local vs systemic), dose, and monitoring plan is essential.

Who benefits and when it helps

DHEA is not a cure-all. Its usefulness depends on the indication, formulation, and how you define success (symptom relief vs biomarker changes vs hard outcomes).

Most consistent benefit: postmenopausal vaginal symptoms (local use).
Prescription intravaginal prasterone 6.5 mg nightly has demonstrated improvements in dyspareunia and vaginal tissue health in postmenopausal women. Clinical guidance documents include vaginal DHEA as an effective option for genitourinary syndrome of menopause (GSM), alongside local estrogen and other therapies. For many, the local route provides symptom relief with minimal systemic hormone changes compared with systemic therapies. ([PubMed][1])

Small, low-certainty benefit: depressive symptoms (systemic use).
A systematic review of randomized trials reports a modest improvement in depressive symptoms versus placebo, but evidence quality is low and dosing regimens vary widely. DHEA is not a first-line antidepressant; if used, it should be adjunctive and clinically supervised with clear stop-criteria. ([PubMed][2])

Mixed/limited benefit: autoimmune conditions.
In systemic lupus erythematosus (SLE) and other rheumatic diseases, reviews suggest modest effects on disease activity, bone mineral density, and fatigue in some studies, often at relatively high oral doses (100–200 mg/day). Evidence quality is variable, and lipid changes (e.g., HDL lowering) are a concern, especially in women. DHEA is an adjunct at best, not a replacement for disease-modifying therapy. ([PMC][3])

Little to no benefit: athletic performance.
Despite its popularity in gyms, DHEA has not convincingly improved strength, lean mass, or performance in controlled studies. It is also prohibited for competitive athletes under anti-doping rules, which creates additional risk. ([Office of Dietary Supplements][4])

Uncertain or not recommended as routine:

  • General “anti-aging.” Evidence for broader vitality, cognition, skin, or metabolic benefits is inconsistent.
  • Adrenal insufficiency quality-of-life. Data show small or no consistent benefits; some patients report mild mood/energy improvement, but androgenic side effects increase with higher doses.
  • Fertility/ovarian response. Findings are conflicting; high-quality trials do not show consistent improvement in pregnancy outcomes. DHEA should not be self-started for fertility without a specialist’s guidance. ([PMC][5])

Who might consider DHEA (with clinician oversight):

  • Postmenopausal women with GSM-related dyspareunia who prefer or need a non-estrogen local option (intravaginal prasterone).
  • Select patients exploring adjunctive options for low-mood symptoms after standard care is in place (short trial, defined exit criteria).
  • Individuals with specialist-managed autoimmune disease considering DHEA as an adjunct (weighing HDL effects and androgenic AEs).

Who should not use or should exercise extreme caution:

  • Anyone with hormone-sensitive cancers, unexplained vaginal bleeding, or significant prostate issues (men).
  • Pregnant or breastfeeding individuals, and those actively trying to conceive without fertility specialist input.
  • Competitive athletes subject to anti-doping rules (DHEA is prohibited at all times). ([Office of Dietary Supplements][4])

How much DHEA per day?

There is no one-size-fits-all dose. DHEA is a hormone precursor that converts variably to androgens and estrogens within tissues, so the right dose depends on the goal, baseline labs, age/sex, and tolerance.

Clinically used ranges (from trials and guidance):

  • Intravaginal prasterone (prescription): 6.5 mg once nightly for moderate-to-severe dyspareunia due to GSM. Studies and position statements support its efficacy as a local option. ([PubMed][1])
  • Oral DHEA (over-the-counter): commonly 25–50 mg/day in “replacement-style” regimens; some trials used 25–100 mg/day for 4–16 weeks depending on the endpoint (mood, bone markers, autoimmune disease activity, etc.). Evidence of benefit is modest and indication-dependent; androgenic AEs rise with higher doses. ([PMC][5], [PubMed][2])
  • Autoimmune adjunct trials: doses often 100–200 mg/day (short-to-medium term) in SLE studies—benefits modest, with lipid trade-offs more common in women. ([PMC][3])

Dosing principles to reduce risk:

  1. Start low, reassess. For systemic use, a 25 mg/day trial is a conservative starting point for adults, with a plan to evaluate benefit and adverse effects in 4–8 weeks. If no clear benefit, stop. ([PMC][5])
  2. Prefer local when local symptoms dominate. For postmenopausal dyspareunia/GSM, intravaginal prasterone (or low-dose vaginal estrogen) targets the tissue with less systemic exposure. ([PubMed][1])
  3. Use time-limited trials. Because many outcomes (mood, energy, libido) are subjective and placebo-responsive, set specific goals and a stop date if those goals aren’t met.
  4. Monitor labs when appropriate. Before systemic DHEA, discuss checking DHEA-S (and in some cases total/free testosterone, estradiol, lipids), then re-check after 6–12 weeks or if side effects emerge.
  5. Avoid stacking. Combining DHEA with other pro-hormones or high-dose “test boosters” increases risk without clear added benefit.

Timing and formulation:

  • Oral DHEA can be taken with the first meal to reduce stomach upset; sublingual forms may raise levels more quickly but also fluctuate.
  • Topical DHEA absorption is variable and harder to monitor.
  • Intravaginal prasterone is inserted at bedtime (single-use applicator).

Do not exceed trial-like doses without a clinician’s oversight, and avoid use altogether if you have hormone-sensitive conditions unless your specialist advises otherwise.

Safety, side effects, and precautions

Because DHEA is a sex-steroid precursor, side effects largely reflect androgen or estrogen activity—varying by dose, sex, and tissue sensitivity.

Common dose-related effects (systemic use more than local):

  • Androgenic: acne, oily skin, hirsutism (excess hair growth), scalp hair thinning, voice deepening (rare, usually with high doses or long duration).
  • Menstrual changes in premenopausal women; gynecomastia or testicular effects in men (less common at replacement doses).
  • Lipids: reductions in HDL-cholesterol reported in some studies, particularly in women at higher doses—consider lipid monitoring. ([PMC][6])
  • Mood/sleep: irritability, restlessness, or insomnia in some individuals.

Local (intravaginal) prasterone:

  • Generally well tolerated; most common effect is vaginal discharge. Long-term endometrial safety beyond 12 months remains under study; guidelines advise individualized risk–benefit discussions and note limited long-term data. ([PubMed][1])

Major cautions and contraindications:

  • Hormone-sensitive cancers (breast, endometrial, prostate): avoid unless your oncology team explicitly approves; DHEA converts to estrogens/androgens. ([PMC][5])
  • Unexplained vaginal bleeding: requires evaluation prior to any hormone-related therapy.
  • Pregnancy and breastfeeding: avoid due to fetal/infant exposure risk and lack of safety data.
  • PCOS or hyperandrogenism: DHEA may worsen acne, hirsutism, or metabolic risk.
  • Cardiometabolic risk: consider lipid monitoring, especially in women or at higher doses.
  • Athletes subject to anti-doping rules: DHEA is prohibited at all times; inadvertent positives can lead to sanctions. ([Office of Dietary Supplements][4])

Drug and condition interactions (selected):

  • Other hormones (testosterone, estrogen): additive effects; higher risk of androgenic or estrogenic AEs.
  • Insulin sensitivity and statins: inconsistent effects; coordinate monitoring if metabolic or lipid therapy is in place.
  • Antidepressants/psychotropics: no systematic contraindication, but any mood-active supplement should be coordinated with mental-health care.

Quality matters: choose products with third-party testing (e.g., USP, NSF) to reduce mislabeling/contamination risk. For athletes, even “clean” supplements are risky given anti-doping standards; when in doubt, don’t use.

DHEA for depression, fertility, and autoimmunity

Depressive symptoms.
Across randomized trials, DHEA has shown small improvements in depressive symptoms versus placebo (standardized mean difference around −0.3 in pooled analyses). Evidence quality is low, and dosing/follow-up vary (often 25–100 mg/day for several weeks). Practical takeaway: if standard care is optimized and a short adjunctive trial is considered, do it with shared decision-making, clear outcome targets, and a stop-plan. ([PubMed][2])

Fertility and ovarian response.
Data are conflicting. Some observational and lower-quality studies suggest improved follicle metrics or oocyte quality in diminished ovarian reserve, but placebo-controlled trials do not show consistent improvements in pregnancy or live birth, and expert reviews advise against routine use. If DHEA is considered in an IVF context, it should be under a reproductive endocrinologist’s supervision with careful dosing (often 25–50 mg/day) and monitoring—and a willingness to stop if no benefit is observed. ([PMC][5])

Autoimmune disease (especially SLE).
Systematic reviews suggest modest benefits (e.g., small reductions in disease activity, improved bone mineral density, and fatigue) with adjunctive DHEA at 100–200 mg/day in some SLE cohorts. Effects are variable, and lipid changes (notably HDL reductions) can occur. DHEA should be reserved for specialist-directed adjunctive treatment when standard regimens are optimized. ([PMC][3])

Genitourinary syndrome of menopause (GSM).
For postmenopausal dyspareunia and related GSM symptoms, intravaginal prasterone 6.5 mg nightly is an effective local therapy endorsed by clinical position statements. It is one of several options alongside low-dose vaginal estrogen and ospemifene; long-term endometrial safety data beyond one year are limited, so individualized follow-up is recommended. ([PubMed][1])

Athletic performance.
DHEA does not reliably improve strength, lean mass, or aerobic capacity in controlled studies—and is prohibited for competitive athletes. If your goal is performance, focus on proven strategies (progressive training, protein optimization, creatine monohydrate, caffeine timing) rather than DHEA. ([Office of Dietary Supplements][4])

How to use and monitor DHEA

1) Clarify your goal and choose the right route.

  • Local GSM symptoms: consider intravaginal prasterone 6.5 mg nightly (or low-dose estrogen) if moisturizers/lubricants are insufficient and you prefer a non-estrogen local hormone. ([PubMed][1])
  • Systemic symptoms (mood/energy/libido): discuss a short, time-limited oral trial only if standard care is optimized; be realistic about modest benefits and androgenic AEs. ([PubMed][2], [PMC][5])
  • Autoimmune adjunct: consider only with your rheumatology team; weigh dose-dependent lipid effects and limited effect sizes. ([PMC][3])

2) Plan shared monitoring.
Before systemic DHEA, agree on baseline tests (often DHEA-S; sometimes total/free testosterone, estradiol, and a lipid panel). Re-check 6–12 weeks after starting or if symptoms change. Track acne, hair changes, sleep, mood, and menstrual changes. Stop if no clear benefit or if side effects appear.

3) Start low and use stop-rules.
A reasonable adult trial is 25 mg/day for 4–8 weeks, then reassess. Some may increase to 50 mg/day if benefits outweigh AEs and labs remain acceptable. For postmenopausal dyspareunia, dosing is fixed at 6.5 mg intravaginally nightly.

4) Avoid risky combinations.
Skip DHEA if you’re taking other sex-hormone therapies unless your clinician coordinates dosing and monitoring. Avoid stacking with “test boosters,” SARMs, prohormones, or potent androgenic supplements.

5) Source carefully.
Choose brands with third-party certification (USP, NSF, Informed Choice). Contamination or mislabeling is common with hormone-adjacent supplements. Competitive athletes should avoid DHEA altogether given anti-doping rules. ([Office of Dietary Supplements][4])

6) Set expectations.

  • Benefits—when they occur—usually appear within 4–8 weeks for mood/energy/libido or within 12 weeks for GSM on local therapy.
  • If the signal is weak or side effects are bothersome, discontinue.
  • Re-evaluate annually (or sooner) if continuing, and periodically consider drug holidays to confirm ongoing need.
