Product Overview


  • Foundation for Longer Life
  • Supports Memory and Hormonal Balance
  • Dietary Supplement


Pregnenolone is biochemically a prohormone. It is made directly from cholesterol within the mitochondria of the adrenal glands and, to a lesser degree, the nervous system, with the help of the cholesterol side chain cleavage enzyme, p450scc. Pregnenolone is a precursor to various hormones, such as progesterone, mineralocorticoids, glucocorticoids, androgens, and estrogens. So it can help the body maintain normal hormone levels, which in turn helps numerous body functions.

Life Extension, Pregnenolone

Posted by 5263594654889177267 on Jun 11, 2015

My PCP recommended this herbal product as an alternative for me. I've only used it for 30 days but anticipate using it for life. To have a health care professional recommend herbal options gives me hope, because I don't like all the Western medicine results. Thanks for the options.

Thanks Life Extension

Posted by 4684294166063330249 on Feb 24, 2015

I'm using these to balance my hormones and I must say they are working. I didn't get my Menstrual Cycle for over a year and usually get only when I go home on breaks. I live overseas. Now with this pill its coming back more so I'm happy that I know the problem is hormonal. I recommend it for anyone with those issues.

Life extension is a quality brand of pregnenolone

Posted by noneofyourfrigginbusiness on Feb 23, 2014

Some studies say that pregnenolone is the most plentiful hormone in the human brain. In other words, it may be made in the adrenal gland but it transports itself through the blood up to the brain. And it has all kinds of necessary functions to control pain. So whatever it takes to bring your pregnenolone level in the blood up to normal levels is what you should take. I personally take 50 mg per day of pregnenolone in the morning without any known side effects.

Best pregnenolone I've tried

Posted by Reviewer1950359 on Jul 02, 2012

This brand has been better than all the others so far (haven't tried the MRM brand yet, though). For me, 50 mgs is a bit too much at once, so I split the capsule and take 1/2 on most mornings, especially before my AM workouts. I save the other half by suspending it in a clothespin or other makeshift holder, making sure the powder doesn't spill out (which sometimes still happens and I lose the other 1/2). This brand of preg helps clear my brain fog and gives me a boost in mental and physical energy. After a few days I also start to notice a subtle improvement in all sexual parameters (refractory period, libido etc; I'm a male in his late 20s). The only real downside at this dose is some water retention if I take it continuously, most likely from the increased cortisol levels (preg flows directly into cortisol in the hormonal cascade). Doses of 50 mgs+ can cause anxiety in some individuals, so start off with a small dose!

I feel I need this, but I do not like the use of magnesium stearate.
