Pregnenolone
Pregnenolone is a steroid precursor whose primary function is to help the body produce other hormones such as progesterone, estrogen, DHEA and testosterone. A person's level of pregnenolone generally declines with age, and by the time we are 75, we have only 40% of the pregnenolone we had when we were 35. Made in the adrenal glands from cholesterol, Pregnenolone helps maintain levels of key hormones while promoting mood and memory enhancement, as well as improved energy levels and enzyme activity.
