This is the one that acts like pregnenolone, isn’t it? All the steroid hormones are derived from pregnenolone. You can see the pathways in this diagram. The natural hormone is also available as a supplement. It’s non-toxic but it tends to be sold in unnecessarily high doses (50-100mg tablets).
If the supplements provide relief, it may suggest issues with cholesterol, thyroid (T3) or vitamin A, since all are necessary to produce pregnenolone. A myriad of other factors can interfere along the pathways, as well as with obtaining the pregnenolone co-factors too. This is one reason I think adrenal fatigue is such a bogus diagnosis.
