The marked decline in serum DHEA with age is believed to play a role in health problems associated with aging. Thus, scientists have been looking at ways of restoring DHEA to youthful levels to prevent or reverse these health issues, and are now discovering mechanisms by which this hormone protects against age-related decline.

Since 1981, several hundred studies have been published on DHEAs various benefits, including immunomodulatory properties as well as positive effects on mood, quality of life, and body composition. It has been proposed that restoring the circulating levels of DHEA to those found in young people may improve well-being and sexual function.

In a recent randomized, double-blind, placebo-controlled study, ten months of DHEA replacement therapy has the beneficial effect of enhancing the increases in muscle mass and strength with the addition of resistance exercise in elderly individuals.*

The studies of DHEA therapy in women with adrenal insufficiency also suggest beneficial effects on well-being, mood, and sexuality.*

DHEA could be of benefit to the normal aging brain. Some studies have reported DHEA may improve mood and alleviate melancholy.* In a recent randomized, double-blinded, controlled trial, DHEA replacement therapy for one year helps to protect hip bone mineral density in older adults and spine bone mineral density in older women.* DHEA has also been shown to support a healthy circulatory system and joint/bone health.*

Life Extensions DHEA directions for use are specially drafted to provide optimal, but safe dosing. The standard blood test to evaluate DHEA status is one that measures DHEA sulfate levels (DHEA-S). The DHEA-S is calculated in micrograms per deciliter (mcg/dL) of blood. A DHEA-S (dehydroepiandrosterone sulfate) blood test may be taken three to six weeks after initiating DHEA supplementation regimen to help determine optimal dosing. When having your blood tested for DHEA, blood should be drawn three to four hours after the last dose. DHEA testing may save you money if it shows that you can take less DHEA to maintain youthful DHEA serum levels.

Because of the overwhelming evidence connecting low levels of DHEA to problems associated with aging, Life Extension suggests that all people over age 40 begin DHEA therapy. For most people, the starting dose of DHEA is between 15-75 mg, taken in one daily dose. Many studies have used a daily dose of 50 mg.

Ideally, DHEA replacement therapy should begin with blood testing to establish a base range. Since almost everyone over age 35-40 has lower than optimal levels of DHEA, most people begin supplementation and test their blood DHEA levels later to make sure they are taking the proper dose. Normal serum reference ranges and ideal ranges of DHEA-S are:

People over age 40, who do not supplement with DHEA, usually have serum levels below 200, and many are below 100 as a steady decline takes place after the third decade in life.*

Some people obtain a baseline DHEA-S blood test before beginning DHEA supplementation. Sometimes it is more economical to have the first DHEA blood test three to six weeks after initiating DHEA. There are precautions that should be observed that are different for men and women.

DHEA precautions for men:
Before attempting to restore DHEA to youthful levels, men should know their serum PSA (prostate specific antigen) level and have passed a digital rectal exam. Men with prostate cancer or severe benign prostate disease are advised to avoid DHEA since it can be converted into testosterone (and estrogen). Therefore, men are advised to have a PSA and digital rectal exam before initiating DHEA to rule out existing prostate disease.

When taking DHEA Life Extension also recommends taking Vitamin E, Ultra Natural Prostate, and Super Absorbable Soy Isoflavones.

It is important for men over 40 to consult their physician to check their PSA and DHEA-S serum levels every six to twelve months thereafter. Men should also periodically check their blood levels for free testosterone and estrogen to make sure that DHEA is following a youthful metabolic pathway.

DHEA precautions for women:
Women should consider estrogen and testosterone testing when they take their DHEA blood test in order to evaluate DHEAs effect on their blood levels of these hormones. Women who have been diagnosed with an estrogen dependent cancer should consult their physicians before beginning the DHEA restoration process.

When taking DHEA Life Extension also recommends taking Melatonin, Vitamin E, Vitamin D3, Gamma E Tocopherol, and Super Absorbable Soy Isoflavones.
