DHEA

Dehydroepiandrosterone (prasterone)

DHEA is a hormone precursor, not an established cognitive or performance supplement. In studies of healthy older or postmenopausal adults it did not reliably improve cognitive performance, while athletes subject to WADA rules face a sport restriction. Compare listed powders and capsules/tablets by form and stated strength, not package weight alone; current catalog data cannot establish a universal per-dose value.

01

What is it?

Not a routine cognitive supplement8
DHEA is a steroid hormone made by the adrenal glands and can be converted to other sex hormones. The evidence on this page does not establish a reliable cognitive or athletic-performance benefit, while hormone and sport-rule implications matter first.

Cognitive benefit has not been established

1

A 2023 systematic review of randomized trials in postmenopausal women found no evidence that DHEA improves cognitive performance.

A year-long trial found no broad benefit

3

In the DAWN trial, 50 mg/day of DHEA for one year did not improve cognitive function, quality-of-life measures, depression scores, or sexual-function scales compared with placebo in healthy older adults. This study dose is research context, not a consumer dosage recommendation.

Names, aliases and forms

AbbreviationsDHEA; DHEA-S
Regulatory NamePrasterone
Chemical NamesDehydroepiandrosterone; 3-beta-hydroxyandrost-5-en-17-one
03

Mechanisms of action

Hormone precursor, not a standard nootropic mechanism

8

DHEA is a steroid hormone that the body can convert into testosterone, androstenedione, and estradiol. That hormone-conversion pathway does not demonstrate a cognition benefit.

04

Potential effects and evidence map

Grade D for cognitive or performance use: randomized studies and systematic reviews in healthy older or postmenopausal adults do not establish a reliable benefit. DHEA can convert to sex hormones, and safety for self-directed use has not been adequately assessed.

Effect domainMagnitudeGrade
Memory / learning1
CumulativeConfidence: High

Evidence does not establish a reliable memory or learning benefit in the studied postmenopausal population.

Note Zero magnitude denotes no established effect, rather than a small benefit.

Safety, side effects and risk profile

Hormonal caution is central8
The NIH ODS summary says DHEA safety has not been adequately assessed. In women who used DHEA for a few months, studies reported increased testosterone, with acne and facial-hair growth.
Hormonal caution8
Confidence: High

DHEA can be converted to sex hormones. The NIH ODS summary says its safety has not been adequately assessed; studies in women taking it for a few months reported increased testosterone, acne, and facial-hair growth.

Note Hormone-related caution is evidence-based, but limited safety data do not establish a blanket high-harm outcome.

3/5
C
Legal / regulatory risk6
Confidence: High

For athletes subject to applicable anti-doping rules, WADA lists prasterone/dehydroepiandrosterone/DHEA under anabolic androgenic steroids in the 2026 Prohibited List.

Note Athlete-specific sport-rule restriction; it is not a general-population legal-risk rating.

2/5
A
Evidence uncertainty8
Confidence: High

For cognitive or performance use, reliable benefit is not established and the NIH ODS summary says safety has not been adequately assessed.

Note Evidence and safety uncertainty are decision limitations, not established high harm.

2/5
B
Reported androgenic effects in women8Acne and facial-hair growth

The NIH ODS summary describes acne and facial-hair growth in women who took DHEA for a few months, alongside increased testosterone in those studies.

06

Interactions and cautions

Review hormone-related care8

The sources used for this profile do not establish a comprehensive medication-interaction list. Because DHEA can change sex-hormone exposure, people using prescribed hormone-related care should have the exact product reviewed by a clinician or pharmacist rather than relying on a generic list.

08

How it compares

How it differs from nootropic claims8

DHEA changes hormone exposure and has not shown a reliable cognitive benefit in the studied populations. The relevant comparison is product form and stated strength after the hormone context has been assessed, not package price alone.

Practical buying and quality notes

  • The current catalog has 22 active listings across 2 vendors: 14 loose powders and 8 capsules or tablets. Eight entries have 2021 crawl dates and multiple listings have no normalized serving dose, so the data cannot establish a universal current per-dose comparison.10
  • Loose-powder package weight and capsule or tablet count are not interchangeable measures. Some 50 mg and 100 mg capsule rows are repeat crawls, so do not count them as independent product evidence when comparing form or price.10
  • A listing without a normalized serving amount cannot support a per-dose comparison. The catalog also includes eight entries with 2021 crawl dates, whose presence must not be read as current availability or current price.10

FAQ

Does research establish a self-directed DHEA dose?

3

No. A 50 mg/day dose was used in the DAWN trial, but it did not improve cognitive or quality-of-life outcomes. Do not convert this research detail into a general dose recommendation.

Who needs sport-rule screening?

6

Athletes subject to WADA or another anti-doping program need to check the applicable rules before use. WADA's 2026 list identifies DHEA and its named synonyms as prohibited anabolic androgenic steroids.

What should a product comparison disclose?

10

Use product form, the stated serving amount, and listing freshness when those fields exist. Do not infer a comparable daily cost from package weight when the serving amount is absent.
