Frequently Asked Questions

What is the difference between pregnenolone and DHEA?

Pregnenolone sits one step higher in the hormone cascade — it converts into DHEA as well as progesterone and cortisol. DHEA primarily converts into testosterone and estrogen. Pregnenolone supplementation may support a broader range of hormonal pathways, while DHEA is more targeted toward sex hormone support. Many practitioners recommend testing both levels before choosing which to supplement.

Can pregnenolone raise cortisol levels?

Theoretically, yes — pregnenolone can convert to cortisol via the progesterone-to-cortisol pathway. However, at typical supplemental doses of 10-50mg daily, significant cortisol elevation is uncommon. The body tends to direct pregnenolone toward whichever downstream pathway is most needed. Individuals with chronic stress or adrenal issues should start at low doses and monitor symptoms.

Is pregnenolone safe for long-term use?

Long-term safety data for pregnenolone supplementation is limited. Short-term studies (up to 8 weeks) at doses up to 500mg have not shown serious adverse effects. However, because it can convert into multiple downstream hormones, long-term use without monitoring could theoretically lead to hormonal imbalances. Periodic blood work and medical oversight are recommended for ongoing use.
