7-Keto DHEA The Fat-Burning Metabolite of DHEA
- Life Extension Magazine, 5/05 -
"By offering many of the advantages of DHEA
supplementation without conversion to estrogen and testosterone, 7-Keto
affords older adults the opportunity to further promote their health and
longevity even when their levels of the so-called “downstream” hormones are
already optimal. Moreover, considering 7-Keto’s demonstrated ability to
improve body composition, it is highly likely that this DHEA metabolite will
become a staple supplement for many aging adults"

The Death of Anti-Aging Supplements? - Life Extension Magazine, 3/03 -
"During these many trials, researchers routinely
found that when taken daily, DHEA supplements effectively reduced
depressive episodes and enhanced mood. In fact, according to one major
study in the UK, as many as 67% of men and 82% of women reported a
noticeable decrease in their depressive symptoms while taking as little as
25 mg/day of DHEA ... DHEA is recognized as one of the major adrenal
androgens, and many of its abilities have been well-documented. We have
learned through years of research that it enhances the immune system, fights
osteoporosis, lowers hyperglycemia (high blood sugar) and may even help to
mount a defense against HIV"

Biotransformation of oral dehydroepiandrosterone in elderly men: significant
increase in circulating estrogens - J Clin Endocrinol Metab 1999
Jun;84(6):2170-6 - "Serum testosterone and
dihydrotestosterone remained unchanged after DHEA administration. In
contrast, 17beta-estradiol and estrone significantly increased in a
dose-dependent manner to concentrations still within the upper normal range
for men [placebo vs. 50 mg DHEA vs. 100 mg DHEA; AUC 0-12 h for
17beta-estradiol, 510 +/- 198 vs. 635 +/- 156 vs. 700 +/- 209 pmol/L x h (P
< 0.0001); AUC 0-12 h for estrone, 1443 +/- 269 vs. 2537 +/- 434 vs. 3254
+/- 671 pmol/L x h (P < 0.0001)]" - That's a 40% increase in the bad
estrogen!!! On top of that, if you are taking testosterone, that increases
estrogen also. See

Sex-specific effects of DHEA on bone mineral density and body composition -
Science Daily, 12/4/18 - "Combining DHEA therapy with resistance exercise that
imparts mechanical strain to bone may promote greater increases in muscle mass

beneficial effects of DHEA replacement on body composition are to modestly
increase fat-free mass in women and decrease fat mass in older men, a reversal
of the usual age-related trends in muscle and fat."

increased five times, equal to those seen in a typical young adult[44] and
similar to increases seen in other studies of older adults using 50-mg/d
supplementation with DHEA.[10,12,17,18,20,32,45] Other studies have reported
increases in estrogen and testosterone levels similar to those reported
here.[10,17,18,45] The increases in estradiol and estrone levels reached

"DHEA is a weakly active adrenal androgen that serves as a precursor to
testosterone and estradiol, which are hormones that can have a positive
effect on mood when administered exogenously. In addition, the authors of
the current study describe that DHEA increases the amount of available
insulin-like growth factor, which in turn can increase levels of growth
hormone. Growth hormone deficiency has also been linked with depressed mood.
Finally, DHEA may modulate inflammatory cytokines, such as tumor necrosis
factor, which may be related to depressed mood"

Disappointing Data Confound Claims For DHEA Effectiveness [against
Alzheimer's] - Psychiatric News, 6/6/03 -
"Twenty-eight patients were blindly chosen to
receive 50 mg of DHEA twice a day for six months ... The dose of DHEA,
Wolkowtiz said, was targeted to achieve blood levels of the hormone at or
slightly above the top of the normal range of DHEA levels found in healthy
young adults ... numerically, DHEA did have a benefit on cognitive ratings,
but overall, on the CIBIC-Plus, there was no significant benefit shown ...
at three months, the DHEA group, compared with placebo, showed a trend
toward improvement on the
ADAS-Cog, but the improvement only narrowly missed being statistically
significant ... DHEA has been reported to reduce
cortisol, the so-called "stress hormone," which
in response to stress is released in large quantities that have been linked
to neuronal stress and damage" - Does anyone detect bias in that
title? I don't know if DHEA helps Alzheimer's or not but I feel the title
should have been something like "Alzheimer's Shows Trend Toward Improvement
with DHEA at 3 Months". Their attitude seems to be that nothing works
except what we write prescriptions for. The way I understand it,
Alzheimer's usually gets worse, not better and
cholinesterase inhibitors slow the disease, they don't reverse it and
three months is a short time to determine if it is working. See

Dehydroepiandrosterone-sulfate (DHEAS) promotes MIN6 cells insulin secretion via
inhibition of AMP-activated protein kinase - Biochem Biophys Res Commun.
2013 Oct 8 - "Although it has the property of
anti-diabetes, the long-term effect of DHEAS on insulin secretion in beta-cells
is still unclear. In this study, the effect of DHEAS on the insulin secretion
activity in MIN6 cell lines in vitro was assessed. Insulin biosynthesis and
secretion were stimulated by DHEAS for 24 h. DHEAS inhibited the AMPK activation
and upregulated the expression of ACC-1. These findings indicate that DHEAS may
exert prominent stimulatory effects on insulin secretion partly via AMPK
inhibition and ACC-1 upregulation"

The use of
dehydroepiandrosterone in the treatment of hypoactive sexual desire disorder: A
report of gender differences - Eur Neuropsychopharmacol. 2012 Oct 17 -
"Data regarding the efficacy of dehydroepiandrosterone
(DHEA) in the treatment of hypoactive sexual desire disorder (HSDD) are scarce
and inconsistent. We aimed to determine possible gender differences in the
efficacy of DHEA as a treatment for HDSS. Postmenopausal women (n=27), and men
(n=21) with HSDD, were randomized to receive either DHEA 100mg daily or placebo
for 6 weeks in a controlled, double blind study ... In women only, significant
interaction effects were observed for sexual arousal (p<0.05), satisfaction
(p<0.05), and cognition (trend; p=0.06). For arousal, a significant improvement
was observed for the DHEA treated group at 6 weeks (p=0.001). Significant
correlations were observed between bioavailable T and sexual cognitions, arousal
and orgasm, while DHEAS was correlated with satisfaction. In the men,
significant correlations were observed between testosterone and arousal (r=.45),
sexual drive (r=.50) and orgasm (r=.55). In women with HSDD, DHEA treatment had
a significant beneficial effect on arousal, whereas no efficacy was demonstrated
in men, indicating a possible gender difference. This improvement seems to be
mediated via DHEA's metabolism to testosterone. Our positive results suggest
that the neurosteroid DHEA may be effective as a treatment for women with HSDD
if administered at a dose of at least 100mg per day"

Diferential
Effect of Oral Dehydroepiandrosterone-Sulphate on Metabolic Syndrome Features in
Pre- and Postmenopausal Obese Women - Clin Endocrinol (Oxf). 2011 Dec 2 -
"To analyze the effect in obese pre- and postmenopausal
women of a daily dose of 100 mg Dehydroepiandrosterone-sulphate (DHEA-S)
provided over a period of 3 months as replacement therapy against
Metabolic-Syndrome ... DHEA-S replacement produced weight loss in the obese
women studied. Moreover, waist-circumference, glucose and systolic and diastolic
blood pressure, among other Metabolic-Syndrome parameters, improved in the
postmenopausal group, who showed a significant reduction in the total
Metabolic-Syndrome Score (P<0.05). In contrast, in premenopausal women, the
effect of DHEA-S was limited to obesity parameters and no effect was observed on
Metabolic-Syndrome components. No significant changes were evident in the
placebo group. Conclusions: An oral dose of DHEA-S is useful for weight loss.
In obese postmenopausal women the hormone significantly improves plasma
biochemical levels and anthropometric characteristics, leading to a better
metabolic profile, which highlights the usefulness of this therapy against
Metabolic-Syndrome in this group of women"

Sep;58(9):1707-14 - "DHEA supplementation resulted in
gains in lower extremity strength (from 459 +/- 121 N to 484 +/- 147 N; P=.01).
There was also improvement in Short Physical Performance Battery score, a

CONCLUSION: DHEA supplementation improved lower extremity strength and function
in older, frail women involved in a gentle exercise program of chair aerobics or
yoga. No changes were found in BMD either due to small sample size, short
duration of study or no effect. The physical function findings are promising and

Protective
effects of dehydroepiandrosterone on atherosclerosis in ovariectomized rabbits
via alleviating inflammatory injury in endothelial cells - Atherosclerosis.
2010 Aug 3 - "The risk for atherosclerosis is increased
in postmenopausal women. Dehydroepiandrosterone (DHEA) is postulated to have
anti-atherogenic properties ... DHEA administration alleviates efficiently the
early pathologic damage of atherosclerosis, increases the serum NO level, and
up-regulates the endothelial cell estrogen receptor (ER) expression of
ovariectomized rabbits. DHEA in vitro significantly promotes NO synthesis,
suppresses MDA and MCP-1 secretion of endothelial cells, and decreases ICAM-1,
VCAM-1 and E-selectin expression in HUVECs; neither selective ERα antagonist
(methyl-piperidino-pyrazole, MPP) nor ERβ antagonist (R,R-tetrahydrochrysene,
R,RTHC) can abolish these effects. Furthermore, DHEA reduces CCR2, LFA-1 and
VLA-4 expression in U937 cells, which in turn inhibits the adherence of
monocytes to the injured endothelial cells. DHEA significantly decreased the
LPS-induced NF-κB transcription"

"All three doses (0.25%, 0.5%, and 1.0%) of DHEA ovules
applied daily intravaginally induced a highly significant beneficial change in
the percentage of vaginal parabasal and superficial cells and pH as well as in
the most bothersome symptom at 2 weeks. At the standard 12-week time interval,
0.5% DHEA caused a 45.9 +/- 5.31 (P < 0.0001 vs placebo) decrease in the
percentage of parabasal cells, a 6.8 +/- 1.29% (P < 0.0001) increase in
superficial cells, a 1.3 +/- 0.13 unit (P < 0.0001) decrease in vaginal pH, and
a 1.5 +/- 0.14 score unit (P < 0.0001) decrease in the severity of the most
bothersome symptom. Similar changes were seen on vaginal secretions, color,
epithelial surface thickness, and epithelial integrity. Comparable effects were
observed at the 0.25% and 1.0% DHEA doses ... Local Prasterone, through local
androgen and estrogen formation, causes a rapid and efficient reversal of all
the symptoms and signs of vaginal atrophy with no or minimal changes in serum
steroids, which remain well within the normal postmenopausal range. This
approach avoids the fear of systemic effects common to all presently available
estrogen formulations and adds a novel physiological androgenic component to
therapy"
