The Core Ingredient Is: Pregnenolone

Pregnenolone is a neuroactive steroid and biological precursor involved in the body's production of other hormones and neuroactive compounds.

This product contains pregnenolone as the main active ingredient, with excipients used for capsule formation. It is presented as a dietary supplement designed to support health in adults.

What Exactly Does Pregnenolone Do?

Pregnenolone takes part in the synthesis of key neurosteroids and hormones, which can influence brain function and mood. Scientific discussion suggests it could support memory formation and neural plasticity in the brain, in line with mechanistic ideas of neurosteroid action.

Dr. Marx from the University found that pregnenolone could influence cognitive function and mood in some contexts, reflecting its role as a hormonal precursor in the nervous system.

This supplement is not meant to diagnose, treat, cure, or prevent any disease.
