Formula contexts for electrolyte drinks
Electrolyte brands position different formulas for different contexts. These pages explain the label patterns, mechanisms, and limits behind those categories. They are educational comparisons, not medical advice or individualized nutrition recommendations.
Keto flu, decoded: mostly a sodium story
The headache, fatigue, and brain fog that hit in the first week of keto are widely described as electrolyte-related — mainly the body shedding more sodium as insulin falls. Here's the mechanism and how keto-positioned formulas are built — educational background, not a personal protocol.

Hangover electrolytes: useful for the dehydration piece
Electrolytes can support the dehydration component of a hangover. They don't reverse alcohol metabolism, disrupted sleep, or nausea — so the honest framing is partial support, not a cure. Here's the mechanism and the formula pattern behind hangover-marketed products.

Oral Rehydration Solution: a four-ingredient formula, decoded
ORS is one of the most-deployed medical interventions in history — a salt-sugar-water formula calibrated against the SGLT1 cotransporter. Here's how the formula works, how it evolved, and how commercial descendants compare. For illness use, follow official instructions or a clinician.

Electrolytes for kids: when plain water isn't the right answer

Here's how the AAP frames it and how pediatric, sports, and adult labels differ. Defer actual child-health decisions to a pediatrician.
