LMNT and SALTT sit in the same narrow lane of the hydration world: high-sodium, zero-sugar electrolyte mixes. Neither is a sports fuel. Neither is a medical oral rehydration solution. Both are tools for people who lose salt and don’t do well on plain water.
Where they differ is how aggressive the formulas are, how much potassium and magnesium they include, and how “clean” or minimalist they aim to be.
What Is LMNT?
LMNT (Drink LMNT) is a zero-sugar electrolyte drink mix sold in single-serve sticks. You typically mix one stick into 16–32 oz of water, depending on taste and sodium tolerance.
LMNT is positioned very clearly as a high-sodium electrolyte, not a sports drink and not a hydration flavor enhancer.
Primary Goal (What It’s Actually For)
LMNT’s purpose is electrolyte replacement, especially sodium, for people who tend to lose or under-consume salt, including:
- Heavy sweaters and hot-climate training
- Low-carb, keto, or fasting lifestyles
- People who drink a lot of water and still feel headaches, fatigue, or “flat”
It’s not designed to:
- Fuel endurance workouts with carbs
- Act as a medical ORS for vomiting/diarrhea
Key Electrolytes (Per Stick)
- Sodium: 1,000 mg
- Potassium: 200 mg
- Magnesium: 60 mg
This profile is intentionally salty. One stick can deliver nearly half of a typical daily sodium guideline in a single serving.
Ingredient Forms (Why They Matter)
LMNT discloses its electrolyte compounds:
- Sodium from sodium chloride
- Potassium from potassium chloride
- Magnesium from magnesium malate / di-magnesium malate
These are straightforward, well-absorbed forms with minimal extras.
Sugar, Sweeteners, and Carbs
- Sugar: 0 g
- Carbs: 0 g
Flavored versions use stevia leaf extract; Raw Unflavored contains only the salts. There’s no glucose, so LMNT does not rely on sodium–glucose cotransport.
Artificial Colors & Label Philosophy
LMNT markets no artificial ingredients and keeps labels short. No dyes are used, and Raw Unflavored is literally just electrolytes.
Bottom Line on LMNT
LMNT is a blunt, minimalist, sodium-first tool. It works very well when sodium loss is the problem—and can be unnecessary or uncomfortable when it isn’t.
What Is SALTT?
SALTT is also a single-serve, zero-sugar electrolyte powder, mixed into at least ~16 oz of water. It’s positioned as “junk-free,” dye-free, and often described as POTS-friendly in its messaging.
SALTT targets people who want high sodium, but also meaningful potassium and magnesium in one serving.
Primary Goal (What It’s Best At)
Support fluid retention and electrolyte balance when sodium loss is real, such as:
- Heavy sweating
- Low-carb or keto diets
- People who don’t retain water well
Like LMNT, SALTT is not an ORS and not designed for GI illness dehydration.
Key Electrolytes (Per Stick, Example Flavor)
- Sodium: 969 mg
- Potassium: 410 mg
- Magnesium: 178 mg
Context:
- Sodium is nearly as high as LMNT
- Potassium is about double LMNT
- Magnesium is much higher than LMNT and may be noticeable for sensitive stomachs
Sugar, Carbs, and Sweeteners
- Sugar: 0 g
- Total carbs: <1 g
Sweetened with stevia RebD/RebM, chosen to reduce bitterness compared with older stevia blends.
No glucose, no maltodextrin, no carb-assisted absorption system.
Artificial Colors & Ingredient Positioning
SALTT explicitly markets “Zero Dyes.”
Key functional ingredients include:
- Sodium chloride + magnesium chloride (SolarSea® Salts AC)
- Potassium chloride
- Malic acid (tartness)
- Acacia gum (mouthfeel)
- Natural flavors
They also highlight what’s not included: no citric acid, no maltodextrin, no dyes.
Bottom Line on SALTT
SALTT delivers a broader electrolyte hit than LMNT—especially potassium and magnesium—while keeping sugar at zero. That makes it appealing to people who want more than “just salt.”
LMNT vs SALTT: Head-to-Head Comparison
| Feature | LMNT | SALTT |
|---|---|---|
| Format | Powder stick | Powder stick |
| Primary purpose | High-sodium replacement | High-sodium + broader electrolytes |
| Sodium | 1,000 mg | ~969 mg |
| Potassium | 200 mg | 410 mg |
| Magnesium | 60 mg | 178 mg |
| Sugar | 0 g | 0 g |
| Carbs | 0 g | <1 g |
| Sweetener | Stevia (or none) | Stevia (RebD/RebM) |
| Artificial dyes | None | None (“Zero Dyes”) |
| Formula style | Minimalist | More complex |
| Best for | Salt replacement | Salt + K/Mg replacement |
| GI tolerance | Usually easier | Magnesium may bother some |
| Cost per stick (approx.) | ~$1.50 | ~$1.00–$1.10 |
Which One Should You Choose?
Choose LMNT If:
- You want maximum simplicity
- Sodium loss is your main issue
- You prefer lower magnesium
- You like very salty profiles
- You want an unflavored option with no sweetener
Choose SALTT If:
- You want high sodium plus meaningful potassium and magnesium
- You sweat heavily and cramp easily
- You want dye-free and citric-acid–free formulas
- You’re price-sensitive within premium electrolytes
Final Verdict
LMNT and SALTT are closer than most electrolyte competitors—but they’re not interchangeable.
- LMNT is a pure, sodium-first electrolyte tool with minimal extras.
- SALTT is a more rounded, high-electrolyte formula that adds substantial potassium and magnesium.
If you mostly need salt, LMNT is cleaner and simpler.
If you want salt plus broader electrolyte coverage, SALTT may feel more complete.
Both are powerful tools. Both can be too much if used casually. The right choice depends on how much you sweat, how you eat, and how your body responds to sodium, potassium, and magnesium.
