Hormone Test Units Conventional reference range (for women) Optimal range (for women) Free T3 (blood spot) pg/ml 2.5-6.5 Top half of normal range (varies by lab), for ZRT 4.5-6.5


According to the UMMC, the optimum levels of DHEA are 180 milligrams per deciliters of blood, or mg/dl, for men; women's optimum DHEA levels should be about 130 mg/dl. The UMMC recommends 50 mg of DHEA per day for men and 25 mg per day for women, though it does not recommend supplemental DHEA for those under 40 years old.


In men, the male hormone effect may not be important if testosterone level is normal. In women, DHEA contributes to normal libido and sexual satisfaction. DHEA may also have effects on the immune system. The DHEA-sulfate test is often done in women who show signs of having excess male hormones.


DHEA levels begin to naturally decline by the age of 30. While normal levels for women in their 20s fall between 65 and 380 µg/dL, for women in their 30s and 40s, the average normal range is 45 to 270 and 32 to 240 µg/dL, respectively. By the time women are in their 70s, their DHEA levels are roughly 20 percent of what they were at age 20.


4. DHEA. Dehydroepiandrosterone (DHEA), a hormone produced by the adrenal glands, is a precursor to the sex hormones estrogen and testosterone. Blood levels of DHEA peak in one’s twenties and then decline dramatically with age, decreasing to 20-30% of peak youthful levels between the ages of 70 and 80.


Continued Results. The normal range for DHEA-S depends on your age, sex, health, and even the way the lab measures the results. A normal level means your adrenal glands are working right.


A host of studies suggest that the lower a person's level of DHEA, the greater his risk of death from age-related disease. DHEA levels in 242 men between the ages of 50 and 79 were tracked for 12 years in a study by noted hormone researcher Elizabeth Barrett-Connor, M.D., professor and chairperson of the department of preventive medicine at the ...


10 Tips to Boost DHEA Levels. It is commonly believed that our body withers and deteriorates with age. As we get older most of us struggle to maintain muscle mass, skin elasticity, & bone mass. We develop conditions such as osteoporosis, osteoarthritis, varicose veins, etc.


Like most hormones, women have optimal DHEA levels in their 20s. After that, DHEA levels slowly decline with aging. There is an 80% decline in DHEA by the age of 70. Age-related decline of DHEA is inevitable, but the decline in DHEA associated with chronic stress and adrenal fatigue is not.


Since almost everyone over age 35–40 has lower-than-optimal levels of DHEA, most people begin supplementation and test their blood DHEA levels later to make sure they are taking the proper dose. The more technology with blue light people use the lower the DHEA rate will be. Normal serum reference ranges and ideal ranges of DHEA-S are:
