Best Electrolytes Supplements 2026: Cost per Effective Dose
Top pick for Electrolytes: Ultima Replenisher Electrolyte Powder (90 servings) — 55mg sodium per 1 scoop, $0.53/day. Our pick.
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 11 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.

Registry check · Electrolytes
Does anyone independently verify Electrolytes supplements?
5 of the 11 Electrolytes products on this page are confirmed in Informed Choice and NSF Certified for Sport: BUBS Naturals Hydrate or Die Electrolytes (20 sticks); Nuun Sport Electrolyte Tablets — Lemon Lime (40 tablets); Redmond Re-Lyte Hydration — Strawberry Lemonade (30 sticks); SaltStick FastChews Chewable Electrolytes — Lemon Lime (60 chews / 30 servings); Transparent Labs Hydrate — Tropical Punch (40 servings). For the others, the listing may name a certification, but we did not find it in a public registry — that is 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.

What Electrolytes labels show
Priced per day, these electrolytes products run $0.52 to $1.85 — a 3.6× gap between the cheapest and dearest electrolytes here, across 10 brands.
Which row that favours is not obvious: Nuun Nuun Sport Electrolyte Tablets — Lemon Lime (40 tablets) is cheapest per serving at $0.52, but its serving sits below the median here, so part of that price gap is simply a smaller capsule.

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 Nuun Sport Electrolyte Tablets — Lemon Lime (40 tablets) showing $0.52 a day, the lowest here, may be reporting a smaller serving rather than a better price. Before comparing Nuun Sport Electrolyte Tablets — Lemon Lime (40 tablets) with BUBS Naturals Hydrate or Die Electrolytes (20 sticks), check what each calls a serving.
