Dhea (or Dehydroepiandrosterone) Is a Powerful and Important Hormone: In Men, Around 50% of Testosterone Is Derived from It; in Women, over 75% of Estrogen Is Derived from It. And, This Number Increases to Almost 100% POST-MENOPAUSE.SUGGESTED Use: Investigators Interested in the Biology of Aging Have Increasingly Focused Their Attention on the Steroids Dehydroepiandrosterone (dhea) and Dhea Sulfate (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.SUPPLEMENTATION with Dhea: The Objective of Supplementation with Dhea Is to Maintain Levels Approximating Those Occurring During Early Adulthood. However, Excessive Amounts of Dhea Can Have Undesirable Effects. Therefore, It Is Important to Ensure That the Amount of Dhea Consumed Is Not Excessive.
