Body System
Kidney
Filtration + electrolyte balance + blood pressure
Your kidneys filter the equivalent of ~50 gallons of blood per day, balancing sodium / potassium / calcium / phosphate to the milligram, making EPO (signals red-blood-cell production), and activating Vitamin D to its hormonal form. The same lifestyle drivers that hammer kidney function â hypertension, insulin resistance, NSAIDs â also deplete magnesium and potassium, so the cofactor list is fragile in the populations who need it most.
