DHEA, short for Dehydroepiandrosterone, is the most common hormone in the human body.  It is made in the adrenal glands from cholesterol and is a precursor to estrogen, progesterone and testosterone production.  Medical research has proven a correlation between elevated DHEA levels and longevity.

Low levels, on the other hand, create a host of problems including a depressed immune system, insulin resistance which can increase the likelihood of diabetes, and increased risk for cancer and heart disease. Due to these issues, it may be beneficial to discuss hormone imbalance treatment with your doctor.
