what it claims

Electrolytes are essential for endurance athletes or those who sweat intensely, but the majority of sedentary individuals do not need fortified drinks, contrary to what marketing strategies suggest.

Science confirms that the body maintains a precise electrolyte balance through the kidneys and standard diet.

Science confirms that the body maintains a precise electrolyte balance through the kidneys and standard diet. For prolonged physical activity (more than 60-90 minutes) or high-heat conditions, meta-analyses and the American College of Sports Medicine recommendations support the use of electrolytes to prevent hyponatremia and support performance (evidence: scientific consensus/RCT). Conversely, for a sedentary individual, sodium and potassium intake is generally sufficient through a balanced diet, making the addition of supplements superfluous. The idea that one must systematically "add" electrolytes to their daily water is a marketing exaggeration without foundation for people who are not active. Norton correctly points out that the need is contextual and not universal. There is no evidence that systematic supplementation improves the metabolic health of sedentary individuals.

What the graded evidence says

Effect: fluid retention by beverage sodium content (beverage hydration index); exercise-associated hyponatremia risk — higher-sodium beverages (and oral rehydration solutions) retained better than plain water over 2-4 h; drinking to thirst rather than overdrinking prevents exercise-associated hyponatremia
Measured on: healthy adults; endurance-exercise contexts

The benefit is context-specific: real for prolonged sweat losses and illness, minimal for everyday sedentary hydration. Marketing tends to sell it as an all-day essential, which the evidence doesn't support.
