DHEA occupies two completely different positions in menopause care, and confusing them is easy. As a vaginal prescription treatment it has evidence and regulatory approval. As an oral supplement bought online it has weak evidence, real side effects, and a claim set that runs well ahead of the research.

Where we stand: Menova is an independent publication. We sell no supplements, we are not your doctor, and this is general education, not medical advice or a dose recommendation.

What DHEA is

A hormone made by the adrenal glands. The body converts it into estrogens and androgens, including testosterone. Levels decline with age, which is the basis for most of the marketing.

The important point: DHEA is a hormone, not a vitamin. It is sold as a dietary supplement in some countries and regulated as a medicine in others.

Vaginal DHEA (prasterone) — the part with evidence

A prescription vaginal insert used for moderate to severe painful sex due to menopause. It is approved for that indication in a number of countries.

How it works: DHEA is converted locally within vaginal cells into estrogens and androgens, which improves the tissue. Systemic hormone levels stay largely within the postmenopausal range.

Points worth knowing:

  • Used daily, unlike vaginal estrogen which moves to twice weekly after a loading phase
  • Trials support improvement in pain during sex, vaginal dryness and tissue quality
  • An alternative for women who prefer not to use vaginal estrogen, or who have not tolerated it
  • Discharge is a common side effect, from the vehicle
  • After breast cancer, discuss with your oncology team rather than deciding alone — see menopause after breast cancer

It is one of several options for genitourinary syndrome of menopause, alongside local estrogen and non-hormonal moisturisers — see how to use vaginal estrogen, GSM and urinary changes, and when sex hurts after menopause.

Availability differs by country, so ask what is licensed where you are.

Oral DHEA supplements — the part that is oversold

Sold widely for energy, libido, mood, ageing, muscle and "hormone balance." The evidence does not support that list.

What reviews have generally found: little consistent benefit for wellbeing, cognition, body composition or sexual function in healthy postmenopausal women. Cochrane and similar reviews of DHEA for menopausal symptoms have been unenthusiastic.

Where there is a genuine medical use: adrenal insufficiency, under specialist supervision. That is a specific clinical situation, not general midlife use.

The Menopause Society and other bodies do not recommend oral DHEA for menopausal symptoms.

Why oral DHEA is not risk-free

This matters more than for most supplements, because it is an actual hormone:

  • It converts to testosterone and estrogen. Androgenic effects — acne, unwanted facial hair, scalp hair thinning, oily skin, and occasionally voice deepening — are reported. Voice change may not fully reverse
  • Unopposed estrogenic effect. If you have a uterus and DHEA raises estrogen, there is no progestogen protecting the womb lining. Report any unexpected bleeding — see bleeding after menopause
  • Hormone-sensitive cancers. Do not take it after breast, ovarian or endometrial cancer without oncology advice
  • It affects blood test results, including testosterone and DHEA-S, which can confuse interpretation. Tell your doctor you take it — see reading your own blood test results
  • Quality varies. Analyses of DHEA supplements have found content differing substantially from labels — see how to tell whether a supplement is worth buying
  • It is a banned substance in most sports
  • Interactions with several medications

The "adrenal fatigue" claim

DHEA is heavily marketed alongside the concept of adrenal fatigue — the idea that chronic stress exhausts the adrenal glands and causes tiredness, brain fog and low mood.

Adrenal fatigue is not a recognised medical diagnosis, and endocrine societies have stated that the evidence does not support it. Adrenal insufficiency is a real, serious and rare condition, diagnosed with specific tests and treated with specific medication — it is not the same thing.

The symptoms this label is applied to are real. They usually have other explanations that are worth pursuing: thyroid disease, iron deficiency, sleep apnea, depression, and the transition itself — see when menopause might not be the answer, perimenopause versus thyroid, and low ferritin in perimenopause.

Salivary hormone panels sold to diagnose it are not validated for that purpose.

If low libido is what you are after

DHEA is commonly bought for this, and there are better-supported routes.

  • Treat pain first. Discomfort during sex suppresses desire, and it is very treatable — see when sex hurts after menopause
  • Testosterone, where indicated, has better evidence for low sexual desire in postmenopausal women than DHEA, and is used in a measured transdermal form with monitoring — see testosterone for women
  • Sleep, mood, relationship context and medication all matter, and antidepressants are a common and reversible cause — see low libido and vaginal dryness

The short version

Vaginal DHEA (prasterone): a legitimate prescription option for painful sex after menopause, with trial evidence. Worth asking about.

Oral DHEA supplements: weak evidence, genuine hormonal side effects, unreliable product quality, and not recommended by menopause societies.

They share a name and almost nothing else.

What to ask

"I have pain during sex from vaginal dryness. Local estrogen hasn't suited me — is vaginal DHEA (prasterone) available here, and would it be appropriate for me?"

And if you already take an oral supplement: "I've been taking oral DHEA. Should I stop, and does it affect any of my blood results?"

Our free printable visit prep sheet has space for everything you take, including supplements — which is exactly the list that tends to be omitted.

This article is general education, not medical advice or a dose recommendation. DHEA is a hormone with real effects and contraindications. Discuss it with a licensed clinician or pharmacist, and with your oncology team if you have a history of hormone-sensitive cancer.
