DHEA

DHEA, produced in the adrenal gland, is the single-most abundant steroid in the human bloodstream. It is often called the ‘mother’ or precursor hormone, because the body readily converts it on demand into active hormones such as estrogen, testosterone, cortisone and progesterone. DHEA declines with age more rapidly in both mean and women beginning at the age of 40. This decline triggers age-related issues and increased susceptibility to disease.
Note: One should not take DHEA unless they are over the age of 40 or have an auto-immune disorder.
