The verdict, first
On the core electrolyte job, LMNT wins — more sodium, lower price, higher score. LMNT delivers 1,000 mg sodium with no sugar at $1.50 a serving and scored 70/100. Waterboy carries 550 mg sodium and costs more at $2.08 a serving, landing at 57/100. If what you want is sodium and simplicity, LMNT does it better for less.
Waterboy’s pitch is the extras. It adds B-vitamins and positions itself around recovery and “the morning after,” which some buyers value as a two-in-one. If those add-ons matter to you and the higher price is worth the convenience, Waterboy has a coherent niche. But as a pure electrolyte mix, it’s paying more for less sodium than the category benchmark.

Sodium and price go the same direction
Usually you pay more for more. Here it’s reversed: LMNT costs less per serving ($1.50 vs $2.08) and delivers more sodium (1,000 mg vs 550 mg), more potassium and more magnesium. Waterboy’s smaller 12-serving tub is part of why its per-serving price runs high. If the electrolytes themselves are what you’re buying, LMNT is the better value on every mineral in the table.
What Waterboy is really selling
Waterboy leans on B-vitamins and a “recovery / morning-after” story rather than raw sodium. For someone who wants a hydration mix that doubles as a B-vitamin top-up, that bundle has appeal, and the taste and branding land well for that audience. Just be clear about the trade: you’re paying more per serving for less sodium, with the vitamins as the reason. LMNT does one thing — electrolytes — and does it at a lower price and a higher score.
Which one fits you
Waterboy makes more sense if…
- You want added B-vitamins and a recovery-focused formula in one mix
- The branding and flavor matter more to you than maximum sodium
- You’re fine paying a premium for the two-in-one convenience
LMNT makes more sense if…
- You want the most sodium (1,000 mg) at the lower price ($1.50 a serving)
- You prefer a clean, electrolytes-only formula with the higher score (70 vs 57)
- You don’t need added vitamins bundled in

Frequently asked questions
Which has more sodium, Waterboy or LMNT?
LMNT, by nearly double — 1,000 mg versus Waterboy’s 550 mg — and LMNT costs less per serving. Waterboy’s draw is added B-vitamins, not sodium.
Why is Waterboy more expensive per serving?
Partly its smaller 12-serving tub and partly the added vitamins and recovery positioning. At $2.08 a serving it’s the pricier option here despite less sodium.
Which scored higher?
LMNT, 70/100, versus Waterboy at 57 — LMNT wins on dose, price and formula simplicity. Waterboy’s extras are real but don’t close the gap.
Does Waterboy have sugar?
No added sugar in the core formula — like LMNT. The difference is sodium dose, price and the B-vitamin extras.
