Safety Profile

Overall safety rating: Generally Safe

Potential Side Effects

  • Nausea or GI discomfort from concentrated electrolyte solutions — dilute appropriately
  • Excessive sodium intake may raise blood pressure in sodium-sensitive individuals
  • Bloating if too much sodium consumed without adequate water

Drug & Supplement Interactions

  • ACE inhibitors and ARBs — potassium-sparing effects; monitor potassium intake to avoid hyperkalemia
  • Diuretics — increase electrolyte losses; may need increased replacement
  • Lithium — sodium intake affects lithium clearance; consistent sodium intake recommended

Maximum Dose

Do not exceed: Individualized — sweat testing can determine personal losses; up to 1500 mg sodium/hr in extreme cases
