What is Pregnenolone?

Pregnenolone is a Specialty supplement available in 1 form.

Not all forms of Pregnenolone are equal. The form you choose determines how much Pregnenolone actually reaches your tissues, and the difference between the best and worst forms can be substantial. Pharmaceutical-grade pregnenolone is the endogenous master steroid hormone precursor synthesized from cholesterol in the mitochondria, serving as the upstream source for progesterone, DHEA, cortisol, and estrogen. Research supports pregnenolone supplementation for promoting healthy neurosteroid activity, memory function, and hormonal balance.

What the Research Shows

Pregnenolone is the master steroid hormone precursor, synthesized from cholesterol and serving as the starting material for cortisol, DHEA, progesterone, testosterone, and estrogen.

How to Choose the Right Form
