DHEA serves as an important adrenal hormone that
supports healthy aging. As a steroid hormone produced from cholesterol by the adrenal glands, DHEA is the most abundant steroid in the bloodstream and is present at high levels in brain tissue. DHEA also serves as a precursor to many steroid sex hormones, including estrogen and testosterone. With age, DHEA production declines usually peaking between the ages of 25-30 and gradually falling to a decline of 90% by age 60.

DHEA seems to support IGF-1 levels (insulin growth factor) and support decreased levels of cortisol. IGF-1 is the hormone or growth stimulating metabolite produced by the metabolism of HGH, and is responsible for the bene cial effects of elevated human growth hormone. Cortisol is a
stress hormone. With aging, there is a decline in DHEA and an elevation of cortisol. High and prolonged levels of cortisol in the bloodstream (like those associated with chronic stress) have been shown to have negative effects such as impaired cognitive performance and suppressed thyroid function,
blood sugar imbalances, decreased bone density, a decrease in muscle tissue, and higher blood pressure with lowered immunity. Besides stress, other factors that contribute to low DHEA levels include: aging, sugar, nicotine, caffeine, alcohol, nutritional imbalances, and a vegetarian diet low in cholesterol and healthy fats.

Studies have suggested that supplementing with DHEA may bene t immune function, blood sugar metabolism, weight management, brain and bone health, heart health, and estrogen and testosterone levels.
