Pregnenolone
Best-in-class: Pregnenolone
The 'grandmother hormone' precursor to all other steroid hormones (DHEA, cortisol, sex hormones), used for memory, mood and hormonal support with age.
How Pregnenolone actually works
The first steroid made from cholesterol and the precursor to everything downstream — progesterone, DHEA, cortisol, aldosterone and the sex hormones. It is also a neurosteroid in its own right, modulating GABA-A and NMDA receptors and enhancing memory consolidation in animal models.
Pregnenolone quick facts
| Suggested dose | 10–50 mg daily; test and go low. |
| How often | Daily |
| Who it's for | Cognitive, mood and hormonal support in older adults. |
✅ Clinically validated
- Studies suggest memory/cognition and mood benefits; it's a potent neurosteroid.
- Declines significantly with age.
📊 Correlative data
- Levels fall substantially with age across populations, which is the entire observational basis for supplementing it. Age-related decline is not by itself evidence that restoration helps — the same reasoning has failed for several other hormones.
🧪 Theoretical / extrapolated benefits
- Because it sits upstream of many hormones, effects are individual and hard to predict.
These tiers tell you how much human evidence exists — not how well something works. This is the research space, and most of what’s in here is new rather than disproven. Something sitting at “theoretical” usually means nobody has funded the trial, not that the trial was run and failed.
The trap runs the other way too: something can be clinically validated and still do very little for you specifically. A statistically significant result in a study population is not a promise about your body.
- ✅ Clinically validated — human randomised trials or meta-analyses support it. The strongest footing available.
- 📊 Correlative — observational or epidemiological data. Suggestive, and genuinely useful for direction, but it cannot establish cause.
- 🧪 Theoretical / mechanistic — the mechanism is understood and often demonstrated in cells or animals, and the human trial doesn’t exist yet. Unproven is not the same as ineffective. Plenty of what’s standard practice today sat here five years ago.
✗ is a safety flag, not a grade. Where you see it, the concern is harm — not a disappointing trial. A compound tested for one purpose and found not to help there can still be worth studying somewhere else, so a negative result never gets rendered as a cross. It sits alongside the tier, because something can be both well-studied and genuinely risky.
My job is to tell you which one you’re looking at, and let you make the call. Grading something low isn’t me dismissing it — it’s me refusing to oversell it. This is the research space, and being able to reason forward from a mechanism matters as much as waiting for the trial.
The 'top up the pool and let the body decide' argument is appealing and mostly wrong — flux down each branch is enzymatically regulated, so supplying more precursor does not reliably direct output where you want it, and it can raise cortisol as easily as DHEA. The neurosteroid effects are the more defensible reason to be interested. Same hormone-sensitive-cancer caution as DHEA, and it suppresses nothing but changes plenty.
Pregnenolone — safety & side effects
- The upstream precursor to everything else in the steroid pathway, which is exactly why it is unpredictable: where it ends up differs between people. Reported effects include irritability, insomnia, headache and acne.
- Suppresses endogenous production with sustained use and can raise downstream hormones you were not targeting.
- Avoid if you have or have had a hormone-sensitive cancer (breast, ovarian, uterine, prostate) without oncology input. The mechanism that makes it useful is the mechanism that makes it a question in that setting.
- Bloodwork before and during, same as DHEA. Not a 'gentle' option because it sits early in the pathway — early means more downstream, not less.
Not medical advice. If you take prescription medication or have a diagnosed condition, check this against it with a pharmacist or doctor — pharmacists are underused and free.
