The review
Why we put this on the shelf.
Pregnenolone is the parent molecule for the body's steroid hormones. Used in clinical practice for cognitive support, stress modulation, and adrenal recovery. Use under guidance of a clinician.
We carry Pregnenolone because Thorne sets a bar most consumer-facing supplement brands don't clear: NSF-certified manufacturing, in-house clinical research with Mayo Clinic and the Mayo Clinic Sports Medicine team, and individual batch testing for purity and potency.
