Evidence-Based Benefits

  • Weight loss enhancement — Zenk et al. (2007, n=33) found 7-Keto 200 mg/day + exercise + calorie restriction resulted in 2.88 kg more weight loss than placebo over 8 weeks
  • Metabolic rate — Zenk et al. (2002, n=45) showed 7-Keto reversed the decline in resting metabolic rate typically seen during dieting
  • Non-hormonal — unlike DHEA, 7-Keto does not convert to testosterone or estrogen, making it safer for long-term use
  • Thyroid support — 7-Keto may increase T3 (triiodothyronine) activity, counteracting diet-induced metabolic slowdown

What the Research Says

7-Keto DHEA has a plausible mechanism (thyroid/mitochondrial metabolic boost) and two positive RCTs, but the evidence base is very small, industry-funded, and both studies are from the same research group. No independent replication exists. The non-hormonal profile is a genuine advantage over DHEA. More research is needed before confident recommendations can be made.
