How Does Pregnenolone Work?
Pregnenolone is a hormone that is used by the body to make all other steroid hormones in the body, including (but not limited to) progesterone, cortisol, aldosterone, testosterone, and estrogen. The body makes it using
cholesterol. In addition to its use as a precursor for steroid hormones, pregnenolone can block the effects of
GABA (
gamma-aminobutyric acid), a brain chemical that can slow down or stop certain nerve signals in the brain.
There is not enough evidence to evaluate the effectiveness of the supplement for any use.
