About Sodium
Primary extracellular electrolyte that regulates fluid balance, blood pressure, and nerve signaling. Most people far exceed the 1,500 mg/day adequate intake through processed foods. The Chronic Disease Risk Reduction (CDRR) level of 2,300 mg/day represents the threshold above which reducing intake provides health benefits. Athletes and heavy sweaters may need more during prolonged exercise. Sodium supplementation is typically only needed in specific clinical scenarios like hyponatremia or adrenal insufficiency.
What Sodium supports
- Maintains fluid balance
- Enables nerve signals
How much Sodium to take
Clinical studies typically use 300–1000 mg of Sodium. Supplemental range for electrolyte/hydration products. WHO ORS provides ~720mg/L. Commercial products range 200–1000mg/serving.
- RDA
- 1500 mg
- Effective range
- 300–1000 mg
Clinical evidence
Strong clinical evidence. Essential electrolyte for fluid balance and nerve signaling; most research focuses on health risks of excess intake
