Dehydroepiandrosterone is a prohormone and a hormone secreted in large amounts by the adrenals in humans and other primates, but not in lower species. It is secreted in larger quantities than cortisol and is present in the blood at concentrations only second to cholesterol. All the enzymes required to transform dehydroepiandrosterone into androgens and/or estrogens are expressed in a cell-specific manner in a large series of peripheral target tissues, thus permitting all androgen-sensitive and estrogen-sensitive tissues to make locally and control the intracellular levels of sex steroids according to local needs. This new field of endocrinology has been called intracrinology. In women, after menopause, all estrogens and almost all androgens are made locally in peripheral tissues from dehydroepiandrosterone which indirectly exerts effects, among others, on bone formation, adiposity, muscle, insulin and glucose metabolism, skin, libido and well-being. In men, where the secretion of androgens by the testicles continues for life, the contribution of this hormone to androgens has been best evaluated in the prostate where about 50% of androgens are made locally from dehydroepiandrosterone.

on a long term basis. Blood and saliva testing are not a reliable way to determine how much
dehydroepiandrosterone supplement one should supplement because blood levels do not give a clear view on how
dehydroepiandrosterone is interacting within each cell in organs and tissues such as brain, skin
and hair, liver, breast, prostate, and other parts of the body. It's better to be safe and proceed with
caution. You may consider other options to improve your health instead of taking
a hormone supplement. For instance, for sexual health consider an herbal sex
product. For mental health, there are various brain supplements. To improve
muscle tissue, consider creatine. But if you do need a DHEA supplement, take the
smallest amount that works to prevent dehydroepiandrosterone side effects.

side effects, risks and dangers including hair loss and heart rhythm problems.
Benefit
This hormone supplement may be of benefit in increasing bone mineral density in
older women, and improving sexual vitality in men and women.
Immune System
Dehydroepiandrosterone and its sulfate (DHEAS) are the main adrenal
androgens produced in humans. Production of these steroids,
like that of cortisol, is under the control of hypothalamic corticotropin-releasing
hormone (CRH) and pituitary ACTH. Other factors, however, appear to be
involved in AA secretion because there are many instances in which their
circulating levels do not change in parallel to those of cortisol. Apart
from physiological alterations associated with fetal adrenal regression,
adrenarche and aging, the main instances of divergence in AA production
compared with those of corticosteroids occur when immune function is
activated or is aberrant. Relative reductions in DHEA and DHEAS have been
noted in subjects with rheumatoid arthritis (RA), systemic lupus
erythematosus, human immunodeficiency virus (HIV) and autoimmune
deficiency syndrome (AIDS), sepsis, and trauma. In some instances,
differences in the AA responses have been linked to a clinical course. The
mechanisms for impairments in AA production in the absence of suppressed
corticoid secretion are unclear but may involve circulating cytokines or
locally released mediators from immune system cells in the adrenal gland.
There also is evidence that DHEA and DHEAS play a role in immune
competence, displaying biological effects opposite to those of
corticosteroids.
Aging
Dehydroepiandrosterone is the major steroid produced by the adrenal
zona reticularis and, in contrast to cortisol and aldosterone, its
secretion declines with ageing. This has generated major interest in its
putative role as an 'anti-ageing' hormone. However, it is not clear that
the age-associated, physiological decline in DHEA secretion represents a
harmful deficiency. DHEA exhibits its action mainly by conversion to sex
steroids. In addition, it has neurosteroidal properties and may exhibit
direct action via specific binding sites on endothelial cells. There is
convincing evidence for beneficial effects in patients with
adrenal insufficiency and future research will hopefully elucidate its
role in patients receiving pharmacological glucocorticoid treatment.
However, in healthy elderly subjects, current evidence from randomised,
controlled trials does not justify the use of DHEA, with no major
beneficial effects reported and, in addition, potentially adverse effects
on sex steroid-dependent tumour growth need to be considered.
Dehydroepiandrosterone and lupus
Effects of dehydroepiandrosterone supplement on
health-related quality of life in glucocorticoid treated female patients
with systemic lupus erythematosus.
Autoimmunity. 2005.
The objective of this study was to evaluate the efficacy of low dose
dehydroepiandrosterone on health-related quality of life (HRQOL) in
glucocorticoid treated female patients with systemic lupus erythematosus (SLE).
Forty one women ( >or= 5 mg prednisolone / day) were included in a
double-blind, randomized, placebo-controlled study for 6 months where dehydroepiandrosterone was given at 30 mg/20 mg daily, or placebo, followed by 6 months open dehydroepiandrosterone
treatment to all patients. HRQOL was assessed at baseline, 6 and 12
months, using four validated questionnaires and the patients' partners
completed a questionnaire assessing mood and behaviour at 6 months.
dehydroepiandrosterone treatment increased serum levels of sulphated
dehydroepiandrosterone from subnormal to normal. The
dehydroepiandrosterone group improved in SF-36 "role emotional" and
HSCL-56 total score. During open treatment,
the former placebo group improved in SF-36 "mental health" with a tendency
for improvement in HSCL-56 total score. Both groups improved in
McCoy's Sex Scale during active treatment. dehydroepiandrosterone
replacement decreased high-density lipoprotein (HDL) cholesterol and
increased insulin-like growth factor I (IGF-I) and haematocrit. There were
no effects on bone density or disease activity and no serious adverse
events. Side effects were mild. We conclude that low dose
dehydroepiandrosterone treatment improves HRQOL with regard to
mental well-being and sexuality and can be offered to women with SLE where
mental distress and/or impaired sexuality constitutes a problem.

Age-related reductions in serum dehydroepiandrosterone concentrations may be
involved in bone mineral density (BMD) losses. The objective was to determine
whether DHEA supplementation in older adults improves BMD when co-administered
with vitamin D and calcium. In year 1, a randomized trial was conducted in which
men and women aged 65–75 y took 50 mg/d oral DHEA supplements or placebo. In
year 2, all participants took open-label DHEA (50 mg/d). During both years, all
participants received vitamin D (16 µg/d) and calcium (700 mg/d) supplements.
BMD was measured by using dual-energy X-ray absorptiometry. In men, no
difference between groups occurred in any BMD measures or in bone turnover
markers during year 1 or year 2. The free testosterone index and estradiol
increased in the DHEA group only. In women, spine BMD increased by 1.7% during
year 1 and by 3.6% after 2 y of supplementation in the DHEA group; however, in
the placebo group, spine BMD was unchanged during year 1 but increased to 2.6%
above baseline during year 2 after the crossover to DHEA. Hip BMD did not
change. Testosterone, estradiol, and insulin-like growth factor 1 increased in
the DHEA group only. In both groups, serum concentrations of bone turnover
markers decreased during year 1 and remained low during year 2, but did not
differ between groups. DHEA supplementation in older women, but not in men,
improves spine BMD when co-administered with vitamin D and calcium.
Dehydroepiandrosterone for
androgen deficiency in women
Very short term dehydroepiandrosterone
treatment in female adrenal failure: impact on carbohydrate, lipid and
protein metabolism.
Eur J Endocrinol. 2005.
In female adrenal insufficiency, dehydroepiandrosterone secretion is
impaired and circulating androgen levels are severely reduced. We wanted
to analyse the acute effects of physiological dehydroepiandrosterone
substitution on substrate metabolism. We studied nine females with adrenal
insufficiency after 9 days of oral dehydroepiandrosterone
replacement (50 mg/day) in a double-blind, placebo-controlled crossover
study. Whole body and regional substrate metabolism was assayed in the
basal state and during a euglycemic hyperinsulinemic glucose clamp by
means of isotope dilution techniques (glucose, phenylalanine, tyrosine),
indirect calorimetry and in situ lipolysis (microdialysis technique).
Treatment normalized the levels of
all androgens. Basal and insulin-stimulated total energy expenditure and
rates of protein, lipid and glucose oxidation were unaffected by dehydroepiandrosterone. Whole body turnover of glucose and protein were
also unaffected by dehydroepiandrosterone. Forearm breakdown of protein
was reduced by insulin to the same extent after placebo and
dehydroepiandrosterone. Insulin sensitivity as expressed by the glucose
infusion rate during the euglycemic clamp was similar after placebo and
dehydroepiandrosterone. Finally, the interstitial release of glycerol in
adipose tissue was not significantly influenced by dehydroepiandrosterone.
Short-term oral dehydroepiandrosterone replacement in
women with adrenal insufficiency was not associated with measurable
changes in total or regional substrate metabolism.

I am a 69 year old male having had a prostatectomy 4 years ago, with
follow up radiation treatment. I am in good health and do take 25 mg of dihydroepiandrosterone,
which completely cleared up my bout with Polymyalgia rheumatica, DHEA improved
my wellbeing significantly.
Hi Dr Sahelian, your website and comments are very
informative. Thank you. I had a question about 5 mg sublingual dihydroepiandrosterone which I am told has is the equivalent of 20 mgs oral. Do
you think this form is safer. Would it be wise to cut tablet in 2
reducing dosage to 2.5 mgs and take one day on one day off?
We can't say whether one form is safer than the
other, I would guess both forms of DHEA, sublingual or oral would not be safe
after a certain dosage and each person has a different threshold after which
side effects would occur, and it is impossible for me to know in your case. As
to the equivalency, we have not come across such research and we don't know what
information this is based on.
