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.”

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.

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.
