DHEA is a hormone produced by the adrenal glands. Research shows that DHEA helps improve sex drive, build muscle and fight the effects of aging. DHEA production in the body peaks in the mid-20s and continuous production gradually declines with age.
DHEA supplements have also been known to increase levels of testosterone and estrogen as production of these hormones also decline with age. In addition to strengthening the immune system and slowing natural changes in the body that come with age, DHEA helps improve mood and energy levels while building up bone and muscle strength.
