Electrolyte Supplement (Sodium, Potassium, Magnesium)
Essential minerals (sodium, potassium, magnesium) that drive hydration, rehydration, and neuromuscular function — most useful when sweat, illness, or low-carb diets deplete fluid and salt.
What the evidence says
Electrolyte Complex doesn't have enough studies with structured effect-size data yet to pool a verdict. Browse the studies below for individual findings.
Most evidence is from high-quality meta-analyses and randomised trials published 1984–2026 with a typical study size of 4,284 participants.

Confidence
High confidenceBy outcome
Cochrane meta-analyses and RCTs strongly establish sodium-containing rehydration for fluid loss and post-exercise hydration, but the popular cramp-prevention claim is not supported, capping the score at strong rather than top-tier.
129 randomised trials
every one checked individually
Every randomised or controlled trial of Electrolyte Complex indexed in PubMed, not a hand-picked subset. Meta-analyses and systematic reviews are deliberately excluded from this count: most of them cover many compounds at once, so counting them would inflate it.

Under EU law (Reg. 1924/2006), EFSA reviews whether a specific health claim for Electrolyte Complex meets the evidence standard. These are independent regulatory decisions on claims — not studies, and never counted toward the evidence score above.
Authorised claims
“Carbohydrate-electrolyte solutions Carbohydrate- electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise”
“Carbohydrate-electrolyte solutions Carbohydrate- electrolyte solutions enhance the absorption of water during physical exercise”
“Not authorised” means the specific claim wording did not meet the EU’s evidence standard — often a matter of dossier or phrasing, not proof of no effect. EFSA judges marketing claims and is kept separate from our study-based evidence score.

Electrolytes are minerals that carry electrical charges and are critical for hydration, muscle contraction, nerve function, and pH balance. Key electrolytes include sodium, potassium, magnesium, and chloride.
The strongest evidence is for rehydration: sodium-containing oral rehydration solutions are well established for replacing fluid lost to diarrhea, illness, or heavy sweating, and adding sodium to fluids improves fluid retention after exercise.
Supplementation is most relevant during intense or prolonged exercise, heat exposure, fasting, keto diets, or acute fluid loss.
Note that the popular idea that electrolyte depletion causes exercise-associated muscle cramps is not well supported — controlled studies point instead to altered neuromuscular control as the main driver.

Requires medical supervision — potassium can be dangerous
Consult doctor — sodium and potassium affect heart rhythm
Generally safe; maintain normal electrolyte intake
Can increase potassium levels — monitor
Only if the product contains potassium, which many electrolyte products do and some do not: added potassium on a potassium-sparing diuretic can cause hyperkalaemia, more so with reduced kidney function. Take a potassium-containing product only if the prescriber agrees and is checking blood potassium.
Can affect electrolyte balance — may need more or less
Electrolyte levels affect heart rhythm
Tip: Take with food; spread doses
Tip: Normal temporary water retention
Electrolyte Complex has an evidence score of 7/10 — strong evidence based on 152 indexed studies, including 3 meta-analyses. Essential minerals (sodium, potassium, magnesium) that drive hydration, rehydration, and neuromuscular function — most useful when sweat, illness, or low-carb diets deplete fluid and salt. Representative study: PMID 27959472.
Dosing for Electrolyte Complex: Sodium 1000-3000mg, Potassium 1000-3500mg, Magnesium 200-400mg daily (varies by needs). These are typical label doses, no cited trial states the dose it used. Individual needs vary — start at the lower end of the range and adjust based on how you respond.
Timing is flexible for Electrolyte Complex — consistent daily use matters more than the time of day. Electrolyte supplementation timing depends on context: before and during exercise for hydration maintenance, after exercise for repletion, or throughout the day during illness, heat exposure, or low-carb diets.
Electrolyte Complex has a safety rating of "moderate". That is a category, not a measure of individual risk, and there are precautions worth knowing. Reported side effects are uncommon and include GI upset (from potassium/magnesium), bloating (from sodium). Use caution if any of these apply to you: Kidney disease (potassium can accumulate); Heart conditions (consult doctor for sodium/potassium); Addison's disease.
