DHEA (Dehydroepiandrosterone)

Adrenal steroid precursor that undergoes peripheral conversion to androgens and estrogens via 3beta-hydroxysteroid dehydrogenase and aromatase pathways. Functions as a neurosteroid modulating GABA-A and NMDA receptors. Endogenous production peaks around age 25 and declines approximately 2-3% annually thereafter.

Notes

DHEA is the most abundant steroid hormone in the human body and it drops every year after 25 like clockwork. The clinical data is clear on the decline. Less clear on whether replacing it changes outcomes. The neurosteroid angle is underappreciated — DHEA modulates GABA and NMDA directly. That is not downstream hormonal conversion. That is direct receptor activity in the brain. Most people supplementing DHEA are thinking about testosterone. They should be thinking about cortisol ratios.
