How it works

Pregnenolone is the primary precursor for all steroid hormones and acts as a neurosteroid in the brain. While it is researched for mood disorders and cognitive enhancement, human clinical evidence is inconsistent and largely limited to specific psychiatric populations.

Acts as a precursor to hormones like DHEA and cortisol while directly modulating NMDA and GABA-A receptors to influence neuronal excitability and mood.
