In the body, pregnenolone is used to make all steroid hormones. There isn't enough information to know how pregnenolone supplements might work.
There isn't enough information to know if pregnenolone is safe when taken by mouth. It might cause some steroid-like side effects including overstimulation, insomnia, irritability, anger, anxiety, acne, headache, negative mood changes, facial hair growth, hair loss, and irregular heart rhythm.
Special Precautions & Warnings:Pregnancy and breast-feeding: Not enough is known about the use of pregnenolone during pregnancy and breast-feeding. Stay on the safe side and avoid use.
Hormone-sensitive condition such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Pregnenolone is converted by the body to estrogen. If you have any condition that might be made worse by exposure to estrogen, don't take supplemental pregnenolone.
EstrogensInteraction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Pregnenolone is used in the body to make hormones including estrogen. Taking estrogen along with pregnenolone might cause too much estrogen to be in the body.
ProgestinInteraction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Progestins are a group of hormones. Taking other hormones along with progesterone pills might cause too much hormones in the body. This could increase the effects and side effects of hormone pills.
TestosteroneInteraction Rating: Moderate Be cautious with this combination.Talk with your health provider.

The appropriate dose of pregnenolone depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for pregnenolone. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
