Found naturally in the body, DHEA (Dehydroepiandrosterone) usually reaches peak levels in early adulthood, then steadily decreases every year afterward. DHEA supplementation has been recommended for restoring youthful vigor and helping to enhance energy and intimacy. Natrol DHEA contains the highest quality of this hormonal precursor available in supplement form.
Making sure you use the proper amount of DHEA is essential for best results. Each Natrol DHEA capsule contains 25 mg of this hormonal precursor, precisely verified by the High Pressure Liquid Chromatography (HPLC) technique.
Investigators interested in the biology of aging have increasingly focused their attention on the steroids dehydroepiandrosterone (DHEA) and DHEA sulphate (DHEAS). When consumed, DHEA is metabolized in the liver, and a significant percentage is converted to DHEAS.
The interest in DHEA and DHEAS stems from observations that circulating levels of these hormones exert beneficial actions but exhibit a unique age-related decline. Therefore, some changes associated with aging are postulated to be due to a relative decline in circulating DHEA and DHEAS.
Secretion of DHEA from the adrenal cortex is very high in a fetus, drops sharply after birth to very low levels in childhood, rises again before puberty and reaches peak levels in young adulthood. It has been conclusively shown that during adulthood DHEA and DHEAS levels in both sexes decrease at a relatively constant rate of 2% per year. Hence, at age 80 levels are only about 20% of those at age 25.
At all ages, the interindividual variability is very high, and thus the normal range of serum levels is extensive. For example, one man at age 65 could have levels three times higher than another man of identical age.
