Dehydroepiandrosterone, or DHEA, is a steroid hormone, a chemical cousin of testosterone and estrogen. It is made from cholesterol by the adrenal glands, which sit atop each kidney. For the first few years of life, the adrenals make very little DHEA. Around age six or seven, they begin churning it out. Production peaks in the mid-20s, when DHEA is the most abundant hormone in circulation. From one’s early ’30s on, there’s a steady decline in DHEA production, so the average 75-year-old has only 20% of the DHEA in circulation that he or she had 50 years earlier. At all ages, men tend to have higher DHEA levels than women
