3,7-keto-DHEA

HormoneDHEA metabolite

Useful mainly for no population has robust evidence of benefit.

Quick decision guide

May help most

No population has robust evidence of benefit

Common dosing range

100–200 mg/day, often split

When to expect effects

Weeks (claimed); unproven

Watch out for

Weak, largely industry-funded evidence; banned in some sports programs

What is it

7-Keto-DHEA (7-oxo-DHEA) is a naturally occurring metabolite of the hormone DHEA that, unlike DHEA itself, is not converted into testosterone or estrogen. It is marketed for fat loss and metabolic rate, but the supporting human evidence is minimal and comes largely from industry-funded studies.

Is it worth it for you?

Use this as a quick fit check, not a diagnosis.

Probably skip if…

You want a fat-loss aid with solid independent evidence
You are a tested athlete (it may be prohibited)
You have thyroid disease and could be affected by metabolic-hormone shifts

Mixed Evidence

A small number of short trials, several funded by ingredient manufacturers, reported modest weight or fat loss with 7-keto-DHEA combined with diet and exercise, sometimes alongside small rises in resting metabolic rate. The studies are small, few, and not independently replicated, and the metabolic-rate findings are inconsistent, so any fat-loss benefit is weak and uncertain.

Bottom line: Evidence for fat loss is thin, conflicting, and largely industry-funded — not a reliable weight-loss aid.

Evidence is mixed

The few supportive trials are small and industry-funded; independent replication is lacking and metabolic-rate effects are inconsistent.

Safety

Know the common side effects, key cautions, and who should avoid it.

Common side effects

Generally well tolerated in short studiesPossible nausea or dizziness

Serious risks

  • Possible shifts in thyroid hormone (T3) reported — clinical significance unclear

Who should avoid it

  • Tested athletes (may be prohibited)
  • People with thyroid disorders
  • Pregnant or breastfeeding people
  • People with hormone-sensitive conditions, as a precaution

Pregnancy & breastfeeding

Avoid — hormone metabolite with no pregnancy safety data.

Interactions

thyroid medicationModerate

Reported effects on thyroid hormone levels could interfere with dosing

DHEA and other hormone supplementsModerate

Overlapping hormonal pathways with unpredictable combined effects

Choosing a product

What to look for on the label — and what to be skeptical of.

Look for…

States 7-keto-DHEA (7-oxo) specifically, not plain DHEA
Third-party tested for identity and purity

Be skeptical of…

“Boosts metabolism” as a guaranteed effect
“Fat-burner” / “effortless weight loss”
“Hormone-free” (it is a hormone metabolite)
