A short list. On purpose.

Sodium

The primary electrolyte lost in sweat.

Sodium maintains fluid balance, blood volume, exercise performance, muscle contractions, and nerve signaling.

Research consistently identifies sodium as the key electrolyte to replace after sweating. Many active adults lose 300-1,000+ mg per liter of sweat, and heavy sweaters can lose considerably more. Most hydration products underdose sodium, BLNC provides meaningful sodium because replacing what is actually lost helps hydration far more effectively than trace amounts.

Potassium

Works alongside sodium inside cells.

Supports muscle contractions, heart rhythm, nerve function, and fluid balance.

Modern diets often fall short of recommended potassium intake because people consume fewer fruits, vegetables, legumes, and potatoes than dietary guidelines recommend.

Magnesium (malate)

Supports 300+ enzymatic reactions.

Contributes to energy production, sleep quality, recovery, muscle relaxation, and healthy nerve function.

BLNC uses magnesium malate because it's generally well absorbed and often well tolerated compared with other forms.
