Renin Activity, Plasma

Renin is a hormone your kidneys release to help control blood pressure and fluid balance. Plasma renin activity shows how hard your body is working to hold onto sodium and water. High or low levels can signal adrenal stress, overtraining, dehydration, or mineral imbalances. It’s a key part of how your system regulates energy, blood pressure, and recovery.
