DHEA (dehydroepiandrosterone), a hormone naturally produced by the body, is synthesized from cholesterol by the adrenal gland. It plays a crucial role in the synthesis and regulation of the steroids and sex hormones in the body such as estradiol and
other estrogens, and testosterone. DHEA can also indirectly influence progesterone synthesis through a feedback mechanism whereby pregnenolone is converted to progesterone based on DHEA levels.
Plasma levels of DHEA begin to decline progressively with age starting around age 40. Research shows that a 70-year-old produces about 90% less DHEA than a person in his or her 20s. It has been proposed that restoring the circulating levels of DHEA to those found in young people may improve well-being. Other factors that contribute to low DHEA levels include consumption of sugar, nicotine, caffeine and alcohol.
Key Ingredients
Aside from its role in synthesizing and regulating hormones, studies show that DHEA is involved in a large variety of physiological processes, including immune function, brain function, bone metabolism, blood lipid metabolism, energy metabolism, the regulation of normal blood sugar and insulin levels, and the maintenance of lean body mass. Research also indicates that supplementation with DHEA (when found to be low) can improve physical, psychological and emotional well-being.
