What is DHEA?
Dehydroepiandrosterone (DHEA) is a hormone that comes from the adrenal gland. It is also made in the brain. DHEA leads to the production of androgens and estrogens (male and female sex hormones). DHEA levels in the body begin to decrease after age 30.
Levels decrease more quickly in women. Lower DHEA levels are found in people with hormonal disorders, HIV/AIDS, Alzheimer's disease, heart disease, depression, diabetes, inflammation, immune disorders, and osteoporosis. Corticosteroids, birth control taken by mouth, and agents that treat psychiatric disorders may reduce DHEA levels.
Orally administered DHEA has a less than 10% bioavailability and is converted into inactive DHEAS, which can then act as a reservoir for the body to utilize. Daily dosing of DHEA 25 mg has been suggested in postmenopausal women because this dose minimizes the adverse androgenic effects; however, only studies in which at least 50 mg/day were used demonstrated positive outcomes.
Dosages used in clinical studies of assisted reproduction were in the range of 50 to 75 mg/day (in divided doses). In adrenal insufficiency, DHEA 50 mg/day for 3 months is considered a replacement dose, while 200 mg/day achieves supraphysiological circulating levels and would thus be considered a pharmacological dose.
Ehydroisoandrosterone (DHEA) ---Medical uses:
In women with adrenal insufficiency and the healthy elderly there is insufficient evidence to support the use of DHEA.
Ehydroisoandrosterone (DHEA) ---Menopause:
DHEA is sometimes used as an androgen in hormone replacement therapy (HRT) for menopause. A long-lasting ester prodrug of DHEA, prasterone enanthate, is used in combination with estradiol valerate for this indication.
Ehydroisoandrosterone (DHEA) ---Cancer:
There is no evidence DHEA is of benefit in treating or preventing cancer. Although DHEA is postulated as an inhibitor towards glucose-6-phosphate dehydrogenase (G6PD) and suppresses leukemia cell proliferation in vitro, DHEA may enhance G6PD mRNA expression, confounding its inhibitory effects.
Ehydroisoandrosterone (DHEA) ---trength:
Evidence is inconclusive in regards to the effect of DHEA on strength in the elderly.
In middle-aged men, no significant effect of DHEA supplementation on lean body mass, strength, or testosterone levels was found in a randomized placebo-controlled trial.
Ehydroisoandrosterone (DHEA) ---Memory:
DHEA supplementation has not been found to be useful for memory function in normal middle aged or older adults. It has been studied as a treatment for Alzheimer's disease, but there is no evidence that it is effective.
Ehydroisoandrosterone (DHEA) ---Cardiovascular disease:
A review in 2003 found the then-extant evidence sufficient to suggest that low serum levels of DHEA-S may be associated with coronary heart disease in men, but insufficient to determine whether DHEA supplementation would have any cardiovascular benefit.
Ehydroisoandrosterone (DHEA) ---Lupus:
There is some evidence of short-term benefit in those with systemic lupus erythematosus but little evidence of long-term benefit or safety.
Ehydroisoandrosterone (DHEA) ---Body composition:
A meta-analysis of intervention studies shows that DHEA supplementation in elderly men can induce a small but significant positive effect on body composition that is strictly dependent on DHEA conversion into its bioactive metabolites such as androgens or estrogens.
