The sodium-to-potassium ratio reflects the balance between these two electrolytes. The body tightly regulates both, so variation in the ratio often points to aldosterone / adrenal activity rather than dietary sodium or potassium alone.
Elevated Na:K ratio is a functional-medicine signal of adrenal stress (cortisol/aldosterone driven). Low ratio can indicate potassium insufficiency or Addisonian patterns. Useful in integrative practice but less clinically established than direct adrenal testing.
Optimal Sodium:Potassium Ratio: 30-35 ratio.
Typically re-tested every 12 weeks.
