Major electrolytes and their function

Sodium

• Regulates fluid balance outside your cells

• Controls BP and Blood Volume

• Initiates nerve impulses and muscle contractions

  • Deficit: Confusion/ zseizures

  • Excess: Intense thirst/ muscle spasm

Potassium

• Maintains fluid balance inside your cells

• Regulate heart rhythm and electrical conduction

• Relaxes muscles to prevent severe cramping

  • Deficit: Muscle Weakness/ Arrhythmia

  • Excess: Severe cardiac arrest

Calcium

• At the bone and the blood

• Triggers muscle contractions throughout the body

• Builds and maintains structural Bone strength

• Enables blood clotting and cell signaling cascades

  • Deficit: Numbness/ Muscle Twitches

  • Excess: Kidney stones/ weakness

Magnesium

• Powers over 300 biochemical reactions as a cofactor

• Inside the cells

• Relaxes BV to lower blood pressure

• Supports healthy immune system and nerve health

  • Deficit: Tremors/ Chronic fatigue

  • Excess: Low BP / Nausea

Chloride

• Balances fluids inside and outside cells alongside sodium

• Produces hydrochloric acid (stomach acid) for food digestion

• Maintains the body’s strict acid-base (pH) balance

Phosphate

• Forms the structural backbone of ATP energy molecules

• Works with calcium to build strong teeth and bones

• Acts as a critical structural component of cell membranes

Bicarbonate

• Serves as the body’s primary chemical pH buffer

• Prevents blood acidity by neutralizing excess metabolic acids

• Recycles carbon dioxide waste safely out of the lungs
