What DHEA does, and whether supplementing makes sense

What DHEA is

Dehydroepiandrosterone (DHEA) is a steroid hormone produced mainly by the adrenal glands, with smaller amounts from the testes, ovaries and brain. In the blood it circulates mostly as DHEA sulfate (DHEA-S), which is what labs usually measure. Levels peak in early adulthood and gradually decline with age.

DHEA itself has modest activity. Its main role is as a raw material that tissues convert into androgens such as testosterone and estrogens such as estradiol. How much is converted, and into what, varies between people and between tissues.

Where the evidence is solid

The clearest example is prasterone, a form of DHEA delivered as a vaginal insert. It is FDA-approved, sold as Intrarosa, for moderate to severe pain during sex caused by menopause-related vaginal changes. The vaginal tissue converts it locally into hormones that help the lining.

DHEA replacement is also used by some specialists for people with adrenal insufficiency, a condition in which the adrenal glands do not make enough hormones. That is a specialist decision, made alongside essential cortisol replacement, not a general wellness choice.

Where it falls short

Trials of oral DHEA in healthy older adults have looked at muscle, strength, bone, body composition, insulin sensitivity, mood, memory and quality of life. Results have generally been small, inconsistent or absent. The 2019 global consensus statement on testosterone therapy for women specifically recommends against DHEA for low sexual desire, citing a lack of benefit.

Part of the problem is that raising a hormone level in the blood does not guarantee a meaningful effect, and the conversion products vary. In women, DHEA can raise androgens enough to cause acne or unwanted hair; in men, it can raise estradiol.

How DHEA is regulated

In the U.S., oral DHEA is sold as a dietary supplement and is exempt from the Controlled Substances Act, while many other countries treat it as a controlled anabolic steroid. Supplement makers are responsible for the safety and labeling of their products before sale, and FDA does not approve them, so contents can differ from the label.

The U.S. Anti-Doping Agency reports that DHEA is prohibited in sport at all times under the World Anti-Doping Agency code, and it is one of the most common prohibited substances found in supplements. Competitive athletes should avoid it unless they have a therapeutic use exemption.

Side effects and who should avoid it

Because DHEA can turn into both androgens and estrogens, it can affect hormone-sensitive conditions in ways that are hard to predict.

• Acne, oily skin and unwanted facial or body hair, especially in women
• Raised estradiol and breast tenderness in men
• Changes in cholesterol or other hormone levels
• Possible interactions with hormone therapy, testosterone and some medications
• People with a history of breast, prostate, ovarian or uterine cancer should avoid it unless a specialist advises otherwise
• Not for use in pregnancy or breastfeeding

Should you test your DHEA-S?

MedlinePlus explains that the DHEA sulfate test is mainly used to check how the adrenal glands are working, to look for adrenal tumors and to investigate signs of excess androgens, such as extra hair growth or irregular periods in women. A low DHEA-S on its own, in someone without symptoms of adrenal disease, is not a reason to supplement.

If fatigue, low libido or muscle loss is what is bothering you, it is usually more useful to check thyroid function, iron, B12, vitamin D, blood sugar and, depending on your sex and age, testosterone or menopausal status.

If you decide to try it

Talk with a clinician first, particularly if you take hormones, have a cancer history or have any liver condition. Choose a product with independent quality testing, start with the lowest dose discussed with your clinician and agree on what you are trying to change. A follow-up blood test can show whether DHEA-S, testosterone or estradiol have moved more than expected, and stopping is reasonable if nothing improves.

DHEA in HealifyMD products

DHEA is one component of HealifyMD's Enclomiphene / DHEA / Boron / Pregnenolone ODT for men. Enclomiphene is the ingredient intended to raise your own testosterone; the combination has not been studied as a whole in clinical trials, and the specific contribution of DHEA is not established. Your clinician will monitor your hormones, including estradiol, if you use it.

The Enclomiphene / DHEA / Boron / Pregnenolone ODT is a compounded product that is not FDA-approved and not equivalent to any branded drug; it is from $129/month, labs are priced separately, and your price is confirmed at the eligibility review.
