DHEA • Produced in: • Adrenal Glands • Gonads • Brain • DHEA Androsterone Testosterone & Estrone • Peaks around 30 years of age • Most abundant steroid hormone © 2010 Meridian Valley Laboratory
DHEA • Low levels associated with • Immune dysfunction • Autoimmune disease • Type II Diabetes • Cancer • Hypertension • Cardiovascular disease • Depression • Cognitive dysfunction © 2010 Meridian Valley Laboratory
DHEA • Low levels associated with • Low libido • Osteoporosis • Suppressed by • Stress • Excess cortisol © 2010 Meridian Valley Laboratory
DHEA • Therapeutic Uses • pro-inflammatory cytokines • Anti-glucocorticoid effects • Increases effectiveness of vaccination • Decreases body fat • Increases lean body mass • Increases insulin sensitivity • May increase activity of exogenous thyroid hormone © 2010 Meridian Valley Laboratory
