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 to 2 tablets daily. 1/2 tablet may be sufficient for some people. Do not exceed 50 mg per day. Do not take for more than 30 days. 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

Dibasic calcium phosphate, microcrystalline cellulose, sorbitol, stearic acid, colloidal silicon dioxide, and magnesium stearate
