Registry check · Electrolytes
Does anyone independently verify Electrolytes supplements?
1 of these 10 products are confirmed in NSF/ANSI 173, which puts this category in the minority with any verified option at all. The other 9 are not listed anywhere we can check — not evidence against them, only an absence of independent confirmation.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the Electrolytes dose column either way.
10 checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What 10 Electrolytes labels show
Priced per day, these electrolytes products run $0.53 to $1.85 — a 3.5× gap between the cheapest and dearest electrolytes here, across 9 brands.
Which row that favours is not obvious: Ultima Ultima Replenisher Electrolyte Powder (90 servings) is cheapest per serving at $0.53, but its serving sits below the median here, so part of that price gap is simply a smaller capsule.
All Electrolytes Supplements Compared
Sodium is the number that decides an electrolyte product, and it is the one the front of the pack rarely leads with. Across the 10 products in the Verified Supplement Data catalog, a single serving ranges from 55 mg to 1,000 mg of sodium — an eighteen-fold spread that makes cost per serving almost meaningless on its own. Match the sodium to your actual sweat loss first, then compare price: around 500 mg suits a hard or hot training session, while a low-sodium mix is closer to flavoured water for that purpose.

The shelf · Electrolytes
These Electrolytes servings are not comparable to each other
Ultima Replenisher Electrolyte Powder (90 servings) states 55 mg a serving and LMNT Recharge Electrolytes — Citrus Salt (30 sticks) states 1,000 mg — both occupy one row of the same price column. So Ultima Replenisher Electrolyte Powder (90 servings) showing 53¢ a day, the lowest here, may be reporting a smaller serving rather than a better price. Before comparing Ultima Replenisher Electrolyte Powder (90 servings) with BUBS Naturals Hydrate or Die Electrolytes (20 sticks), check what each calls a serving.

The evidence · Electrolytes
What the published reviews of Electrolytes concluded
- The diagnostic power of salivary electrolytes for Sjögren's disease: a systematic literature review and meta-analysis. · Clinical and experimental rheumatology, 2023
“Despite differences in saliva type, salivary ion levels could be utilised for the screening for SjD.”
- Comparison of Salivary Electrolytes Profile in Oral Potentially Malignant Disorders and Oral Squamous Cell Carcinoma. · Asian Pacific journal of cancer prevention : APJCP, 2022
“High salivary Mg levels can be a potential biomarker indicating the presence of OPMD, however, the evidence is still contradictory and more studies are required.”
- Comparison of the effectiveness of polyethylene glycol with and without electrolytes in constipation: a systematic review and network meta-analysis. · BMC gastroenterology, 2016
“Polyethylene glycol with and without electrolytes are effective and safe treatments for constipation in adults. The addition of electrolytes to polyethylene glycol does not appear to offer any clinical benefits over polyethylene glycol alone in the management of constipation.”
- The Role of Electrolytes in Muscle Pain Syndromes: A Systematic Review and Meta-Analysis With Implications for Temporomandibular Disorder. · International dental journal, 2026
“Magnesium supplementation benefits pregnancy-related cramps but shows inconsistent effects in other populations. Sodium-based interventions are context-specific, and calcium and potassium remain unsupported. Magnesium is the most plausible candidate for translation to TMD myalgia, warranting targeted clinical trials.”
Method: PubMed searched in humans for systematic reviews and meta-analyses with Electrolytes in the title; these 4 of the 6 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether Electrolytes will work for you — each of these reports an average across trials published 2016–2026, and null findings are shown here as readily as positive ones.
