DHEA is produced in the adrenal glands and is a precursor to both testosterone and estrogen. DHEA also affects bone density, response to stress, mood and cognitive function, improves insulin sensitivity, and is associated with decreased cardiovascular and cancer risk. It peaks in the mid-20s and begins to decline after 30. Longevity is associated with higher than age-normal levels of DHEA. Low levels may be a sign of adrenal stress and/or reduced androgen production. Adrenal support and meditation can increase DHEA levels, or supplementation may be appropriate. High levels are common with PCOS or may be a sign of over-supplementation.
