Pregnenolone
A precursor hormone that supports cognitive function, mood, and memory.
Overview
Pregnenolone is a steroid hormone produced in the body from cholesterol. It is a precursor to many other hormones, including DHEA, progesterone, testosterone, and estrogen. Pregnenolone is often referred to as the 'mother hormone' because of its role in the production of these other hormones. Levels of pregnenolone naturally decline with age, which has led to interest in pregnenolone supplementation as a way to support healthy aging. Research on pregnenolone has focused on its potential benefits for cognitive function, mood, and memory. Some studies suggest that it may help to improve memory and learning, reduce symptoms of depression, and enhance overall well-being. It is also being investigated for its potential role in the treatment of conditions such as Alzheimer's disease, schizophrenia, and bipolar disorder. However, more research is needed to confirm these benefits.

Scientific Research
The neurosteroid pregnenolone promotes degradation of key proteins in the innate immune signaling pathways
Pregnenolone and its metabolic derivatives have been shown to have beneficial effects in the brain, including enhancing memory and learning, reversing cognitive deficits, and exerting neuroprotective actions.
Proof-of-Concept Trial with the Neurosteroid Pregnenolone Targeting Cognitive and Negative Symptoms in Schizophrenia
Pregnenolone was generally well-tolerated and associated with significant reductions in negative symptoms.
