Electrolyte Supplements Compared
This comparison looks at sodium, potassium, and magnesium disclosure, sugar and sweetener profile, third-party testing status, serving format practicality, and dated price per serving across five electrolyte product reviews. Default sort reflects SuppCheckr weighted scores — not medical recommendations and not suitability for any specific condition.
Default table order is based on SuppCheckr weighted criteria scores, not a ranking of which product is right for every person or any medical use case. SuppCheckr does not rank electrolyte products for dehydration treatment, hangover recovery, cramp prevention, keto, fasting, pregnancy, children, or any medical condition. Filter and re-sort by price per serving or testing status to match your own label and sourcing priorities.

How to use this comparison
This table is a label and sourcing tool — not a medical recommendation. Scores summarize dose transparency, form clarity, testing documentation, additives, and dated manual price context using our methodology. They do not determine which product is right for you or suitable for any health condition. Use filters to re-sort by price per active dose or testing status when those criteria matter more to you.
Scores use the electrolytes scoring profile (sodium/potassium/magnesium dose transparency, electrolyte composition clarity, sugar and sweetener disclosure, label clarity, evidence alignment and claim conservatism, third-party testing documentation, dated price per serving, formula quality including serving format practicality, additives, and brand transparency). Table order defaults to overall score high to low. Narrow criterion labels below each product name reflect specific supported label attributes — not broad recommendations, condition-specific winners, or universal-suitability framing. Scores are not medical recommendations and do not determine which product is suitable for dehydration treatment, illness recovery, hangover prevention, cramp prevention, athletic performance, pregnancy, children, or any medical condition. Consult a qualified healthcare professional before using electrolyte drink mixes, especially if pregnant, nursing, under 18, taking medication, managing blood pressure, kidney disease, heart disease, fluid restrictions, or a medical condition. See /methodology for weight details.

Comparison caveats
- Thorne Catalyte NSF Certified for Sport status is verified via listing id 1286726 (reconfirmed Phase 14F). Supplement Facts locked from Vitacost retailer label (UPC 693749006299) with iHerb corroboration because the official thorne.com PDP did not expose a complete panel during review. NSF database nutritional summary cites 20 cal / 3 g sugar vs retailer Supplement Facts 30 cal / <1 g sugar / 5 g carbohydrate — label-grounded retailer values retained with documented NSF variance. Formula includes taurine, B vitamins, and other nutrients beyond core electrolytes.
- LMNT Citrus Salt lists 1,000 mg sodium per stick with 0 g sugar. High sodium may be inappropriate for some people managing blood pressure, kidney disease, heart disease, fluid restrictions, or certain medications — NIH sodium context only, not product recommendation. No verified third-party sport certification captured. Keto/fasting brand copy is not endorsed by SuppCheckr.
- Ultima Replenisher Lemonade lists 55 mg sodium per stick with 0 g sugar and broad mineral disclosure. Added vitamins and minerals (vitamin C, zinc, manganese, phosphorus) beyond core electrolytes. Low sodium is a label attribute, not dehydration treatment positioning. No verified third-party certification captured.
- Nuun Sport Lemon Lime discloses sodium, potassium, magnesium, calcium, and chloride per tablet with 1 g sugar from dextrose. Tablet dissolve step adds serving friction. Brand rehydration copy is not performance or illness-treatment framing. No verified third-party certification captured. Lowest observed $/serving ($0.75) at 2026-07-15 check.
- Liquid I.V. Hydration Multiplier lists 500 mg sodium, 370 mg potassium, and 11 g sugars per stick. Magnesium is not disclosed on the cited US Nutrition Facts panel — documented as not disclosed, not zero. Hydration Multiplier and faster-hydration marketing carry high claim-risk; SuppCheckr cites label facts only. No verified third-party certification captured.
- All five products in this comparison have affiliate.enabled false. No Amazon affiliate links or ASINs. Product images remain branded placeholders.
- Phase 14C price context (2026-07-15): Nuun $7.49, Ultima $20.99, Thorne Target $34.00, LMNT $45.00, Liquid I.V. $24.99. Verify current price at the retailer before purchase.
