Aldosterone is produced by the outer section (zona glomerulosa) of the adrenal cortex in the adrenal gland from corticosterone, a steroid derived from cholesterol. Aldosterone’s role in the body is to increase the retention of sodium and water and to increase the excretion of potassium by the kidneys, playing a central role in the regulation of blood pressure.  When dysregulated, aldosterone is pathogenic and contributes to the development and progression of cardiovascular and renal disease.
