The Health Benefits of Pregnenolone
Pregnenolone is a naturally occurring steroid hormone that serves as a precursor to several other hormones and is marketed as a dietary supplement. Emerging research suggests it may boost memory, lessen depressive symptoms, improve cognition in early schizophrenia, and curb cravings for alcohol and cocaine, with study doses ranging from 50 mg to 500 mg per day. However, the evidence base consists mainly of small trials, and the supplement can produce steroid‑like side effects and hormone‑related risks. Experts recommend medical consultation before use.
