consider pregnenolone to try and help with low dhea??
Nope, sorry. The actual scientific literature doesn't bear any of that out. It's just his opinion.
I do agree to work on the state of the HPA axis to optimize cortisol and DHEA production on your own but there is zero evidence that taking it long terms shuts down the adrenals.
There is also no evidence that DHEA lowers cortisol further once it is already too low. If that were the case, people with Addison's would not see benefit from supplementing DHEA and the literature clearly shows an increase in well being from supplementation.
It's a common misconception though so I understand how one could be mislead.
FWIW, I counted at least three factual mistakes in the Holtorf presentation. Take that video with a grain of salt...most notably that Florinef shouldn't be taken by those with high blood pressure. Florinef can normalize high blood pressure as well. It's not cut and dried.
Researchers use a dose of 50 mg DHEA per day in most studies. In 2006 Italian researchers published the results of a study on the effect of a considerably lower dose of DHEA on cortisol levels. [Gynecol Endocrinol. 2006 Nov;22(11):627-35.]
The Italians gave their test subjects – women aged between 50 and 55 [dark bars on the figure below] and between 60 and 65 [light coloured bars] – a daily 25 mg DHEA for a period of 12 months. 0 = cortisol level before DHEA supplementation started; 2 = after 3 months; 3 = after 6 months; 4 = after 12 months

Abstract
OBJECTIVE:
The aging process is associated with a decline in the circulating Delta5-androgen dehydroepiandrosterone (DHEA) and its sulfate ester, dehydroepiandrosterone sulfate (DHEAS). The present study aimed to evaluate the effects of a long-term (12 months) oral DHEA administration (25 mg/day) on adrenal function, before and after 3, 6 and 12 months of treatment.
METHOD:
Postmenopausal women belonging to two age groups, 50-55 years (n = 10) and 60-65 years (n = 10), were studied. Adrenal function was assessed in basal conditions, after suppression with dexamethasone (DXM) and following a stimulation test with adrenocorticotropic hormone (ACTH) (10 microg bolus). Serum levels of DHEA, DHEAS, androstenedione (Delta4-A), allopregnanolone, 17-hydroxyprogesterone (17-OHP) and cortisol were measured and the effects of DHEA supplementation on specific adrenal enzymatic pathways were evaluated by calculating precursor/product ratios (17-OHP/cortisol, 17-OHP/Delta4-A, DHEA/Delta4-A and DHEA/DHEAS).
RESULTS:
DHEA supplementation annulled the age-related differences in DHEA and DHEAS levels and induced a marked increase in all steroids, except for cortisol, after 3-6 months of treatment. Serum cortisol levels decreased from the 3rd month, both in younger and older subjects. DHEA supplementation did not affect DXM-induced suppression of adrenal steroidogenesis. During the treatment period all adrenal androgens and progestins showed a significant increase in their response to ACTH, while the cortisol response decreased significantly. The results suggest a significant DHEA-induced change in adrenal enzymatic activities, as also evidenced by the change in precursor/product ratios during therapy.
CONCLUSION:
Chronic DHEA administration is capable of modifying circulating levels of androgens and progestins in both early and late postmenopausal women by modulating the age-related changes in adrenal function.
Neither of those articles (while certainly interesting) address whether or not DHEA continues to lower cortisol levels once they are already low or can permanently suppress the adrenal's production of those hormones and those are the points under debate.No need to apologize. Here is some "actual scientific literature."

I use a 7-keto DHEA transdermal. From what I understand, the 7-keto does not raise estrogen and testosterone. I'm not sure what its effect on cortisol is.

Yes, I don't know anyone with AI that can get by without replacement HC.Very interesting @Ema . I'm curious if you know if those with Addisons who find benefit from DHEA are also supplementing cortisone? I'm guessing they are, but would appreciate your feedback.
Also, this study was posted on another thread, but it's a little vague, and the dose of DHEA was high:

There's no doubt that DHEA can lower cortisol. I just don't know if it continues to do so once the cortisol level is low or insufficient. I would doubt it though and if the DHEA level is low, I think supplementation is worth a try no matter where the cortisol level falls out in the range.
Addison's is adrenal insufficiency. Typically, primary adrenal insufficiency (as opposed to secondary or tertiary) but the end result is the same...not enough cortisol.AI -- do you mean 'adrenal insufficiency'? That's quite different from Addison's...
Agree to disagree about what exactly? I'm confused! Any medical textbook will tell you Addison's equals primary adrenal insufficiency.Well, I guess we'll have to agree to disagree, but thanks.
Addison’s disease (also Addison disease, chronic adrenal insufficiency, hypocortisolism, and hypoadrenalism) is a rare, chronic endocrine system disorder in which the adrenal glands do not produce sufficient steroid hormones (glucocorticoidsand often mineralocorticoids)
