Pregnenolone has been associated with the support of mood, the immune system, and memory. It also provides assistance to the hormones in the body, as it is a natural predecessor to 150+ steroid hormones. Pregnenolone may assist in memory enhancement by regulating gamma aminobutyrate (GABA) and N-methyl-D-aspartate (NMDA) activity in the brain. For immune health, one Pregnenolone study suggested that the 7-hydroxy metabolites in Pregnenolone could possibly assist in immune system response. It’s also been reported that Pregnenolone helps encourage feelings of motivation and wellbeing through dopamine release.
