Product Overview


  • Dietary Supplement

Pregnenolone is the starting point from which all steroid hormones are manufactured in our bodies. Its conversion in the body follows different pathways, depending on individual needs. Several clinical studies have demonstrated that pregnenolone may enhance psychomotor performance and decrease fatigue in healthy subjects.

Suggested Use

1 tablet daily. 1/2 tablet may be sufficient for some people. Do not exceed 1 tablet per day. Do not take for more than 30 days without the advice of your physician, and have your blood hormone (estrogen, testosterone, DHEA) levels regularly assessed by your physician. Using pregnenolone may elevate your DHEA levels, and DHEA can increase estrogen and testosterone levels. Read entire label before using.

Other Ingredients

Sorbitol, mannitol, modified cellulose gum, colloidal silicon dioxide, stearic acid, and magnesium stearate.


Not for use by individuals under the age of 18 years. Do not use if you are pregnant, may become pregnant, or breastfeeding.

Do not exceed recommended serving. Exceeding recommended serving may cause serious adverse health effects. Possible side effects include acne, hair loss, hair growth on the face (in women), aggressiveness, irritability, and increased levels of estrogen.

I like Source Naturals and was happy to see them offering Pregnenolone at a good price. My doctor suggested I try this for brain fog - it works!

In combination

Posted by iHerb Customer on Apr 25, 2014 | Verified Purchase

I am using this in combination of Vinpocetine, Huperzine A and L-Tryptophan to help with my memory. I can actually say I have been able to tell that I have better recall since I started taking it. zine A
