The era of relying on sugary sports drinks like Gatorade is over. While some benefit from the added sugars for fuel, others long for those electrolytes1 essential for basic life functions and proper hydration.  

Enter LMNT, awarded one of the best electrolyte drinks for its low sugar content and ample electrolytes. This popular powder has many advantages—including its high-quality formulation—yet it might not appeal to all. 

If you’re wondering if LMNT suits you, you’ve come to the right place. In this LMNT Electrolyte Review, join me, a dietitian, as I delve into the specifics and share insights from Nicole Davis, GGR head of content. Let’s get into it!

A Quick Look at LMNT Electrolyte Drink Mix 

Robb Wolf, co-founder of LMNT, discovered a game-changing element in his health routine. “I’d been on a low-carb, whole-food diet for years, but something was missing,” Wolf explains. The missing piece? Adequate salt intake.

Wolf’s journey led him to create LMNT, an innovative alternative to high-sugar electrolyte drinks. This formulation took Robb’s fitness, sleep, and brain functioning to new levels, and he hopes LMNT can be as meaningful for you.

Before You Buy

  • Sodium content: LMNT packs a substantial 1,000 milligrams (mg) of sodium per serving, nearly half the daily reference intake recommended by the Food and Drug Administration2 (FDA)—more details on this to come!
  • Salty flavor: Given its high sodium content, LMNT might be too salty for some. The brand suggests diluting it with 32 ounces of water for a more balanced “salty” experience rather than an overwhelming “salty AF” taste with just 16 ounces.
  • Refund policy: The good news is that if you find the flavor unenjoyable or still too salty after dilution, LMNT provides a no-questions-asked refund or exchange policy.

Is LMNT Worth It?

At over $1.50 per serving before tax, LMNT is costlier than many of the best electrolyte powders, which tend to average around $1.25 per serving. However, its distinctive flavors and robust formulation might make it a worthwhile investment for some.

Great for:

  • Boosting electrolyte intake, especially in hot environments, during endurance exercise, or when you’re sick and have lost a lot of fluid
  • Those seeking an electrolyte solution without added sugars or artificial ingredients
  • Most diets, including gluten-free, vegan, Paleo, low-carb, and keto diets

Not recommended for:

  • People who don’t enjoy a pronounced salty taste
  • Budget-conscious consumers
  • Those limiting or monitoring their sodium intake due to health concerns like high blood pressure or heart failure

Experience Using LMNT

Nicole Davis, GGR head of content, tested LMNT and tells us: “I was constantly parched during my pregnancy and this was a real thirst-quencher. No sugar, either, which I can appreciate. Since giving birth, I only drink these if I know I’m going to be sweating a lot, like during/after a long run—they work for sure!”

Price Per Serving

A 30-count pack of LMNT costs $45 ($1.50 per serving) for a one-time purchase or $39 ($1.30 per serving) with a subscription. Conversely, the 120-serving INSIDER Bundle offers $0.98 per serving for a single purchase and $1.13 per serving with a subscription. Despite the more economical rates of the bundle, its upfront cost of $117 to $135 might deter some, resulting in a price value rating of 2 out of 5.

Formulation

We rated LMNT’s formulation a shining 5 out of 5 stars, and here’s a rundown of its star players: 

  • Salt as Sodium Chloride (1,000 mg of sodium): Sodium is crucial for maintaining fluid balance, particularly in the extracellular fluid (the fluid outside the cells), which influences blood pressure and supports normal nerve and muscle functions. While many health organizations recommend 2,300 mg daily, ongoing recommendations3 suggest up to 5,000 mg may benefit most healthy individuals unless they are salt-sensitive.4 Endurance athletes5, in particular, might require as much as 600 milligrams per hour of training. 
  • Potassium Chloride (200 mg of potassium): As the primary electrolyte within cells (intracellular fluid), potassium is essential for fluid balance like sodium. It also promotes muscle contractions, blood pressure regulation, and heartbeat control. The recommended intake of potassium6 ranges between 3,500 and 4,700 mg daily.
  • Magnesium Malate (60 mg of magnesium): Magnesium is essential for muscle and nerve function, maintaining healthy heart rhythms, and regulating blood glucose levels. The Recommended Dietary Allowance (RDA) for adults is 310 and 420 mg of magnesium7 daily, depending on age and sex.

Beyond essential electrolytes, all LMNT flavors contain citric acid, natural flavors, and stevia leaf to enhance taste and sweetness. They’re also free of added sugars, artificial coloring, and other unnecessary fillers and additives. 

Taste and Solubility 

Nicole has a lot to say about LMNT: “Flavors are really unique…Chocolate Salt? I ordered the variety pack that had Citrus Salt, Raspberry Salt, Orange Salt, and Watermelon Salt. This tastes salty, I won’t sugar coat it! It’s an acquired taste. BUT, on my third packet, I actually started to dig it. Most reviews praise the taste, though there are people who also feel it tastes too salty.” 

Coop partakes in some LMNT Electrolyte goodness.

Considering the varied opinions, we award LMNT a score of 4 out of 5 for taste yet a perfect 5 out of 5 for its exceptional solubility.

Side Effects

Nicole encountered no negative side effects and praises the product’s effectiveness, saying, “People love this stuff for its purpose, to help hydrate.” Given this positive feedback, we award LMNT a commendable 5 out of 5 in this category.

However, individuals managing high blood pressure, kidney disease, or other underlying health conditions, or those on certain medications, like diuretics, should consult a healthcare professional.

Third-Party Testing 

LMNT manufactures its products in a National Sanitation Foundation (NSF)-certified facility compliant with Good Manufacturing Practices (GMP), but they do not undergo third-party testing. The company is transparent about this choice, categorizing LMNT as a beverage, not a supplement, which justifies using a Nutrition Facts label instead of a Supplement Facts label.

Coop mixes LMNT in a cup by pouring in water from a relatively high altitude.

Regardless, the lack of third-party testing, a critical factor for athletes, results in a lower rating of 2 out of 5 in this category.

LMNT vs Liquid IV 

Liquid IV

Liquid I.V. Hydration Multiplier

product image
GGR Score: 3.6

Product Highlights

  • Cellular Transport Technology for rapid absorption
  • Three times the electrolytes of a sports drink
  • Contains 5 essential vitamins
  • Non-GMO and free of artificial ingredients

Pros & Cons

Pros

  • Hydrates faster than water
  • Travel-friendly
  • Contains essential vitamins
  • Charity donations made with every purchase

Cons

  • Can be too sweet for some
  • Stevia can cause GI distress for some people

Bottom Line

Liquid I.V. Hydration Multiplier is a great product to help boost your hydration quickly, especially for people who prefer a less-salty electrolyte drink.

Liquid IV is another popular electrolyte product like LMNT, yet it stands out in many ways:

  • Electrolyte content: Contains half the amount of sodium (ranges between 500 to 510 mg, and Pear provides 630 mg) and almost double potassium (370 to 390 mg) without magnesium.
  • Carbs: Provides up to 13 grams of carbs to meet the World Health Organization’s (WHO) standards for an oral rehydration solution (ORS) for rapid hydration. However, a sugar-free option is available as a low-carb, keto-friendly alternative.
  • Added nutrition: Provides vitamin C, B vitamins, and others depending on your multiplier choice.
  • Purposes: Various “Multipliers” for hydration, sleep, energy, and immune support
  • Flavors: Offers 13 fruity flavors for more variety, but no unflavored option. 

If you’re looking for an electrolyte solution to help fuel you during endurance exercise and you like a sweeter flavor, Liquid IV might be the better choice for you. For a detailed comparison, refer to the table below and our Liquid IV Review.

Final Verdict of Our LMNT Electrolyte Review

LMNT is a sugar-free electrolyte powder formulated to provide 1,000 mg of sodium, 200 mg of potassium, and 60 mg of magnesium. If you’re considering shaking LMNT in your water bottle, consider these final thoughts:

LMNT: FAQs

Who should not drink LMNT?

Individuals with hypertension, kidney disease, and other conditions that require sodium restriction should exercise caution with LMNT. Additionally, anyone taking medications that can alter fluid balance—like diuretics and blood pressure drugs—may need to avoid LMNT and other electrolyte powders. 

What are the side effects of LMNT electrolyte powder?

LMNT electrolyte powder may cause electrolyte imbalances, primarily due to its high sodium content. Excess sodium can lead to hypernatremia, characterized by elevated sodium levels in the blood, which may result in symptoms such as tachypnea (rapid, shallow breathing), difficulty sleeping, and restlessness.1

Why does LMNT taste so salty?

LMNT might be an acquired salty taste because it contains 1,000 milligrams of sodium derived from salt.
