For many years DHEA, or dehydroepiandosterone, was considered a junk hormone, since researchers could not attribute any specific function to it. In the past few years, DHEAs image problem has been totally refurbished. It is the most abundant hormone in humans and other mammals, and it plays a critical role in many different bodily functions. In fact, decrease in DHEA levels is being increasingly used as an indicator of reduced immune response, and lack of a sense of general wellbeing. Clinical studies over the past ten years show that DHEA may be the most critical single chemical in predicting health.The body produces DHEA in the adrenal gland using cholesterol as the starting material. It is metabolized to androstenedione, which is converted directly to testosterone. Like testosterone estrogen in women and other critical hormones, DHEA levels peak in the second or third decade of life, after which the decline begins. In men, roughly one-half of DHEA is lost by age 40. Reduced levels of DHEA mean reduced amounts of androstenedione, testosterone and other steroid hormone metabolites. It is interesting to note that as cholesterol in general increases with age, DHEA levels decrease.DHEA directly affects glucose metabolism. High blood glucose inhibits growth hormone GH and low blood glucose stimulates growth hormone. Stimulation of growth hormone is beneficial to DHEA, because it suppresses insulin. By the same token, fasting increases both GH and DHEA. Thus, the importance of DHEA in intense exercise and endurance training can hardly be overemphasized. In fact, Dr. William Regelson of Medical College of Virginia in his book The Superhormone Promise calls DHEA the superstar of hormones and one |
