Scientists at the University of California, San Diego, performed a study on 13 men and 17 women, ranging from 40—70 years of age. These subjects were given 50 mg of DHEA orally every night for six-months. In men, however, only androstenedione levels increased slightly, while testosterone and dihydrotestosterone levels were unchanged Figure 5.

DHEA has been implicated in reducing the protein content of the PPARy receptor in fat cells, as well as sterol regulatory element-binding protein and adipocyte lipid-binding protein.

A study in aged rats with 0. Fatty acid absorption does not appear to be influenced with DHEA supplementation. DHEA's oxygenated metabolites metabolites that are not androgenic or estrogenic steroids have been noted, in Caco-2 cells in vitro model for intestinal cells to have anti-proliferative properties and may suppress carcinogenic growth. A few studies conducted in the past, usually open label, associated DHEA supplementation with improvements in mood when given to older individuals with lower circulating DHEA levels.

DHEA is thought to increase well-being due to the ability of DHEA supplementation to increase circulating levels of beta-endorphins and other neurosteroids assocaited with happiness in the body [] [72] and the brain. This is in contrast to any state of adrenal insufficiency, where low circulating levels of DHEA are due to low-activity adrenal glands rather than the age-associated decline.

In this state, DHEA supplementation is effective at increasing mood and well-being more than placebo. PSA is a biomarker used to measure prostatic hypertrophy and risk for prostate cancer.

DHEA Dosing and Safety Precautions

Studies on DHEA supplementation in men measuring PSA note either no increases in circulating PSA levels at mg daily for a year [] or 6 months [] and at 50mg over the short-term [] [65] or 6 months. In vitro , DHEA appears to be able to increase PSA secretion from prostate cells only if cancerous and to a lesser potency than that of other androgens like testosterone. This section is mostly thanks to a thorough review that compiled many studies, although further studies have been added.

This is a further metabolite of 7-Keto DHEA, and is the result when a single bond on the A ring between carbons 3 and 4 is turned into a double bond. This turns the 5-Androstene designation into 3,5-dien , as the -en refers to a double bond and the di refers to two. Surprisingly, it is a natural metabolite found in the urine as this change from 7-Oxo the addition of a double bond appears to occur in the body somewhere [] perhaps in the liver.

This conjugate appears to possess competitive aromatase inhibiting activities, with an IC 50 of 1. One study investiating DHEA inconjunction with an aromatase inhibitor AI found that the combination was more potent at increasing testosterone than either in isolation 8. DHEA side effects inducing 'androgenic' side-effects in women appear to be rare, but exist.

A few studies note increased occurrence of acne when DHEA is taken orally, but this does not appear to affect all persons. Even rarer, but still reported, are instances of increased facial hair growth in women.

Dehydroepiandrosterone

Grade Level of Evidence Robust research conducted with repeated double-blind clinical trials Multiple studies where at least two are double-blind and placebo controlled Single double-blind study or multiple cohort studies Uncontrolled or observational studies only. Level of Evidence? The amount of high quality evidence. The more evidence, the more we can trust the results.

Summary of Dehydroepiandrosterone

The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect. Scientific research does not always agree. There appears to be a notable and unreliable increase in estrogen following DHEA supplementation, with most research being conducted in menopausal women. This increase in estrogen has been noted in men as well, although similarly unreliable.

There appears to be an increase in testosterone following DHEA supplementation, but the vast majority of literature is in menopausal women where testosterone contributes to libido. There is variability in the results, and DHEA is unreliable in increasing testosterone, but this unreliability extends to all demographics and subjects with limited evidence of DHEA increasing testosterone in all studies including youthful athletes, which are less studied.

Highly unreliable influences on cortisol, with decreases seen in studies where androgens and estrogens are also increased with no significant influence or possibly an increase in other studies. An increase in IGF-1 hormone levels may exist following DHEA supplementation, although this has only been investigated in older persons. Most evidence suggests no increase in bone mineral density, but this may be due to short trials 6 months.

Longer trials note a small but unreliable increase in bone mineral density, so there may be a role of DHEA in bone health. No significant influence on fat mass appears to exist with DHEA supplementation in youth or in elderly persons. Most evidence measuring functionality in elderly persons have not found any improvement with DHEA supplementation, although it is possible that DHEA may play a role.

Perhaps due to a lack of studies pairing DHEA with a prolonged resistance training program, there is no evidence to support DHEA supplementation to increase muscular or lean mass.
