It has sodium lactate (C₃H₅NaO₃) with a molecular weight of 112.06 g/mol. Sodium has a major role in maintaining cell integrity along with potassium. Sodium maintains the proper muscle and nerve functions. Low sodium levels develop hyponatremia condition with symptoms like muscle cramps, headache, restlessness, nausea, fatigue, confusion, hallucinations, decreased consciousness, and coma.
