Both Re-Lyte and LMNT are low-sugar electrolyte mixes, but their amounts differ—especially for potassium and sodium. This comparison uses flavored Re-Lyte and LMNT Citrus Salt as the standard servings; Re-Lyte Unflavored has a different electrolyte profile. Prices below are U.S. brand-site prices checked October 13, 2026.
Carbs
A serving of flavored Re-Lyte lists 0 grams of total carbohydrates. LMNT Citrus Salt lists 1 gram of total carbohydrates per packet, so Re-Lyte has the lower listed carb count. For most people comparing these two products, the difference is small, but it may matter if you’re tracking every gram.
Cost
By current list price, Re-Lyte’s 60-serving tub costs $45.99, or about $0.77 per serving. LMNT’s 30-pack costs $45, or $1.50 per packet at the one-time price. On those package options, Re-Lyte’s tub costs less per serving.
The package format changes the comparison: Re-Lyte’s 30-count stick packs are $40.99, about $1.37 each. LMNT lists its 30-pack subscription at $39, about $1.30 per packet, and its 120-pack bundle at about $1.13 per stick. These are brand-site prices before taxes or other offers, and may change.
Sodium
A serving of flavored Re-Lyte provides 810 mg of sodium; LMNT provides 1,000 mg. That makes LMNT the higher-sodium option by 190 mg per serving. There’s an important exception: Re-Lyte Unflavored provides 1,000 mg of sodium, matching LMNT on this measure.
Magnesium
Flavored Re-Lyte provides 50 mg of magnesium per serving, compared with 60 mg in LMNT. The difference is 10 mg per serving. Re-Lyte Unflavored also provides 60 mg, according to Redmond’s listed amounts.
Potassium
Potassium is where flavored Re-Lyte has the larger amount: 400 mg per serving, compared with 200 mg in LMNT. Re-Lyte Unflavored provides 500 mg. So if potassium content is a priority in this comparison, Re-Lyte supplies more per serving—whether flavored or unflavored.
Sugar
Both products report 0 grams of sugar on their labels. Redmond’s FAQ adds a detail for flavored Re-Lyte: those flavors contain less than 1 gram of naturally occurring sugar from coconut water powder; Re-Lyte Unflavored has none. LMNT Citrus Salt lists 0 grams of sugar.
Conclusion
Re-Lyte offers more potassium and a lower cost per serving when you buy the tub; LMNT offers more sodium and slightly more magnesium in its standard packet. For carbs and sugar, both are low, but the labels differ: flavored Re-Lyte lists 0 g carbs while LMNT Citrus Salt lists 1 g, and both list 0 g sugar. Re-Lyte Unflavored changes the mineral comparison, providing 1,000 mg sodium, 500 mg potassium, and 60 mg magnesium. The better fit depends on which of these amounts and package prices you care about most.
