40 min

This episode of Huberman Lab Essentials focuses on hormone optimization for males, highlighting the critical role of lifestyle factors like sleep, stress management, and moderate exercise. Dr. Kyle Gillett discusses key supplements (creatine, L-carnitine, Tongkat Ali) and emphasizes that blood work should monitor free testosterone, SHBG, and vitamin D. He cautions against using testosterone therapy in younger men with normal levels and notes that tadalafil can improve prostate health without affecting hair loss.

✨ Key Takeaways

1

Creatine does not significantly speed up hair loss—it only brings testosterone-to-DHT conversion to your natural baseline.
2

Tongkat Ali supplements (300-1200 mg/day) can increase free testosterone and LH, especially in those with high SHBG.
3

Tadalafil (2.5-5 mg/day) improves prostate health, reduces nighttime urination, and increases androgen receptor density.
4

Don't train vigorously for longer than one hour—it is hormonally counterproductive for testosterone optimization.
5

For men in their 20s-40s with normal testosterone levels, taking exogenous testosterone is rarely beneficial and carries many risks.
