Natural Testosterone Optimization
Huberman's natural testosterone framework leans on foundations first: sleep, resistance training, and less stress and alcohol. Healthy body composition matters too, and his supplement stack, zinc, tongkat ali and fadogia agrestis, comes second and is unevenly supported; he tracks bloodwork rather than guessing, and this is not testosterone replacement therapy.
This is Andrew Huberman's framework for supporting natural testosterone. He is explicit that the foundations matter most: sleep, training, body composition, stress and alcohol move testosterone far more than any pill. On top of that he uses a small supplement stack, some of it genuinely contested. He does not present this as testosterone replacement therapy, and he tracks his blood markers rather than guessing.
Why it works▼
Sleep 7 to 9 hours, consistently
Much of testosterone is produced during sleep; short or fragmented sleep measurably lowers it. This is the single biggest free lever.
Lift heavy, don't over-do endurance
Resistance training supports testosterone; chronic excessive endurance and overtraining can lower it. Build strength and recover.
Get body fat into a healthy range
Excess body fat raises conversion of testosterone to estrogen; very low body fat and very low dietary fat also suppress it. Aim for the middle.
Cut alcohol and manage stress
Alcohol and chronically high cortisol both suppress testosterone. Morning sunlight, breathwork and stress control help protect it.
Zinc and vitamin D
Zinc and vitamin D support normal testosterone, but mainly by correcting a deficiency. Topping up beyond normal will not push levels higher.
Boron
Boron may lower sex-hormone-binding globulin, slightly raising free testosterone. Evidence is modest; treat as optional.
Tongkat Ali
A 2022 meta-analysis found tongkat ali raised total testosterone versus placebo, but independent reviewers note the evidence in healthy men is limited. Buy a standardized extract if you try it.
Fadogia Agrestis (we don't sell this)
Fadogia acts as a luteinizing-hormone mimic, but it has almost no human safety data and animal studies showed testicular toxicity at higher doses. Huberman cycles it and later came off it. We describe it for completeness and deliberately do not sell it; if you consider it, do so only with a doctor.
Creatine
Creatine supports training performance and recovery, which indirectly supports the foundations. Modest direct hormonal effect.
Test your blood, don't guess
Huberman tracks markers rather than guessing. Driving testosterone up without watching estradiol can backfire. Test before and after any change.
- Men who want to support testosterone without TRT
- People willing to fix sleep, training and body fat first
- Anyone who wants the honest evidence behind the popular stack
- Data-minded people who will actually test their blood
- This supports your body's own testosterone; it is not testosterone replacement therapy (TRT). TRT is a medical decision with real trade-offs, including reduced fertility, and is not something we sell or dose.
- We deliberately do not sell fadogia agrestis. It has minimal human safety data and animal studies showed testicular toxicity at higher doses. If you consider it, do so only under medical supervision.
- Tongkat ali's evidence in healthy men is limited and contested; treat any testosterone supplement as optional and unproven, not a guarantee.
- Do not drive testosterone up without monitoring estradiol; rising testosterone can raise estrogen. Test your blood before and after changes.
- These doses are for adult men and can cause unwanted effects in women, including virilization; women should work with a hormone specialist. Anyone with a hormone-sensitive condition or on medication should consult a physician first.
