LMNT Review: Is this Electrolyte Powder Worth the Hype?

At Top Nutrition Coaching, we only recommend brands we trust, all of which are selected and reviewed by our dietitians. We may receive compensation for this content, which was created in partnership with Live it Up.

Part of my passion as a registered dietitian is evaluating products to determine if they're right for my clients' nutritional goals and needs. I've had a recent influx in requests for the best electrolyte drink mixes that support hydration, so I thought I'd take a closer look at some of the more popular offerings on the market. 

Here, I'm focusing on LMNT Electrolyte Drink Mix, a top player in the electrolyte supplement space since 2018. This LMNT review takes a close look at the drink's ingredients, formula, health claims, costs, and customer testimonials to provide you with a detailed view of the product, including its benefits, potential downsides, and which competitors might be better (hint: there may be other electrolyte powders out there that better suit your needs). 

LMNT Key Features

• What is LMNT? LMNT is a sugar-free, low-carb electrolyte powder, featuring three electrolytes, only 5 calories, and a higher sodium content that may be conducive for athletes.
• How should you use LMNT? The company recommends mixing one packet of LMNT in 16–32 ounces of water, depending on your preferred saltiness levels.
• How well does LMNT hydrate? For balanced cellular fluids, a balanced sodium-to-potassium ratio is important for effective hydration. LMNT's ratio of approximately 5:1 is heavily weighted toward sodium.
• Are there better alternatives to LMNT? LMNT might be beneficial for intense athletes, but for those looking for daily hydration, check out Live it Up Vital Minerals, which offers half the sodium, three electrolytes, vitamin C, a coconut water powder base, and five refreshing flavors.
• How much does LMNT cost? One box of 30 stick packs costs $45 ($1.50/stick) for one-time orders or $39 ($1.30/stick) for subscriptions. LMNT also offers a 120-pack bundle that comes out to $0.97/stick.
• What are the alleged LMNT benefits? LMNT claims to support daily hydration, exercise recovery, sleep quality, cognitive function, and natural energy levels.
• What does LMNT taste like? LMNT tastes salty, but many of the flavors balance the salt level with fruit-forward tanginess and sweetness from stevia.

LMNT Overview

The idea for LMNT began in 2018, when cofounder Robb Wolfe was training athletically and found that his body needed more salt to perform at its highest level. But he wasn't finding low-sugar hydration options that provided enough electrolytes—and that's when the cofounding team formulated LMNT, launching what they call the "salty rebellion."

LMNT comes in several flavors and is offered in stick packs for on-the-go athletes. The company later launched its LMNT sparkling product line in 2024, which offers the same electrolyte and nutritional profile as the stick packs but in canned form.

My Overall Thoughts on LMNT

I'm happy to see that LMNT doesn't have any added sugars or artificial flavors, contains few calories, and features three crucial electrolytes. But the sodium levels may be higher than what many individuals need for daily hydration for many individuals, and the cost might be prohibitive for daily use. 

LMNT Ingredient Analysis

LMNT's ingredients are pretty typical of many electrolyte powders, but let's take a closer look at each one.  

• Sodium chloride: This is a standard form of salt used in electrolyte mixes. However, LMNT uses 1,000mg of sodium chloride to fuel its electrolyte powder, a high sodium level that might not be best for daily use.
• Potassium chloride: Potassium is an essential mineral that works in concert with sodium to hydrate your body's cells.
• Magnesium malate: This form of magnesium is believed to be highly bioavailable, meaning that your body absorbs it better than other forms of magnesium.
• Malic and citric acid: Found naturally in many fruits, malic and citric acids are likely used as flavor enhancers and pH stabilizers in LMNT. 
• Stevia leaf extract: Just because LMNT is sugar-free doesn't mean that it isn't sweet. Stevia leaf extract makes this possible by delivering 200–300 times the sweetness of sugar without the sugar high.
• Natural flavors: LMNT uses natural flavors to enhance its electrolyte powders. Though, you can also purchase the Raw Unflavored stick packs if you prefer not to have a flavored beverage.

LMNT Health Claims

Let's uncover whether LMNT's five health claims are supported by science.

Daily Hydration

LMNT Electrolyte Drink Mix contains three electrolytes to support hydration: sodium, potassium, and magnesium. While these are three of the most replenishing electrolytes, I have a couple of concerns: 

• Excess sodium. Our bodies require sodium to function properly, but there is such a thing as too much. In the United States, the recommended daily sodium intake is less than 2,300mg, nearly half of which is delivered in one serving of LMNT. While you can lose anywhere from 200-2,000mg of sodium in one liter of sweat, the amount depends on your body's makeup, the intensity of the workout, and whether you're in a hot environment. With that in mind, I wouldn't recommend LMNT for daily hydration, as it likely provides too much sodium for the everyday user.
• Potentially unbalanced sodium to potassium ratio. Sodium and potassium work together to regulate fluid balance in our body's cells, so getting the ratio of these minerals right is crucial in electrolyte mixes. Some research and formulations suggest a ratio in the range of 2:1 or 3:1 (sodium to potassium), while LMNT uses a 5:1 ratio, which differs from those commonly referenced ranges.

Supports Exercise Recovery

Magnesium and potassium play crucial roles in nerve function and muscle contraction. While potassium has been shown to reduce the frequency and severity of leg cramps, results of magnesium are mixed. Some studies show that the mineral may help relieve muscle soreness, delay muscle fatigue, and help alleviate muscle cramps. However, the general consensus is that more rigorous studies are needed to provide more clarity.

Aids Cognitive Function

Potassium supports brain function by helping your brain cells communicate with one another. In one study of mice, researchers found that increasing potassium levels resulted in better learning and memory performance. Additionally, a lack of sodium may lead to impaired cognition, specifically confusion and fatigue.

Contributes to Natural Energy Levels

Because electrolytes don't contain calories, they don't directly influence energy—but they can do so indirectly. For example, magnesium is a key player in the synthesis of ATP, which is what cells use as their main source and storage of energy. Meanwhile, potassium helps metabolize carbohydrates, which triggers the body's processes for energy creation. These processes may help some individuals feel like they have more energy.

Supports Sleep Quality

Magnesium plays a role in the production of melatonin, sometimes called the sleep hormone, so some healthcare professionals recommend supplementing with magnesium to get better sleep. But the type of magnesium matters. According to research, the best form for supporting sleep quality is magnesium glycinate (LMNT contains magnesium malate). 

Additionally, the amount of magnesium may influence its effect on sleep. In one study of older adults, researchers found that 500mg of magnesium supplementation increased sleep duration and decreased sleep latency. LMNT contains 60mg of magnesium, so it's unclear how much of an effect it will have on sleep.

LMNT Prices and Discounts

Product and shipping costs, as well as return policies, are important factors when deciding on the right electrolyte supplement. Take a look at LMNT's costs and find out how they compare to some competitors.

Customer Testimonials

When clients come to me with electrolyte product questions, I, of course, share my experience with and research of the hydration drink, but it's also important to do a deep dive on other customers' experiences. Testimonials can shed light on the purported effectiveness of a product—and provide insights into any unwanted reactions. 

Here's what some customers have to say in their LMNT salt reviews.

LMNT Taste and Texture

There are 10 LMNT flavors to choose from: 

• Citrus Salt
• Grapefruit Salt
• Watermelon Salt
• Orange Salt
• Raspberry Salt
• Mango Chili
• Chocolate Salt
• Chocolate Caramel
• Lemonade Salt
• Raw Unflavored

I rated LMNT a 4 out of 5 for taste, I tried Citrus Salt and found it to be extremely salty but also well-balanced with the tanginess of the citrus flavoring. The sweetness from stevia also helps to offset the salt-forward taste. While I didn't try the Raw Unflavored option, I'm curious if that mix will suit the taste buds, as there are no natural flavors or sweeteners to counteract the saltiness.

Overall, LMNT zero-sugar electrolyte drink mix reviews are positive, with reviewers Have noted that the product is flavorful but not overly sweet, and others have praised it, claiming that "it doesn’t have an artificial or syrupy aftertaste that some other electrolyte products may have.

As for the salt level, it might not be everyone's preference. Next time, I'll add more water to my glass or water bottle, like one customer suggests: "If you’re sensitive to salty drinks or prefer something mild, you might want to dilute it with extra water."

LMNT gets high marks for its dissolubility, with many reviewers (myself included) noting that it mixes well in water, leaving "no gritty residue, so every sip is smooth and enjoyable." 

LMNT Reported Results

According to LMNT zero-sugar electrolytes reviews, LMNT seems to be effective with hydration and workout recovery, with reviewers have noted that they feel more hydrated and have more energy after exercising and others mentioning that the hydrating effects are tangible.

Other customers appreciate that LMNT seems to help their sleep quality, with some saying that they're "getting better sleep at night due to fewer muscle cramps."

But results of any supplement, including sports drinks, may be inconsistent, as every body is different. Some customers report side effects of LMNT, such as migraines and digestive issues.

Did You Know? Common side effects of magnesium include stomach upset, diarrhea, and nausea, especially at higher doses. Some individuals may be more prone to these side effects than others, but it's always a good idea to be aware of how much magnesium you're getting from other sources, such as your whole food diet, as the recommended daily allowance of the mineral is between 310mg and 420mg.

Final Thoughts on LMNT

LMNT does several things well, from offering zero-sugar hydration and key electrolytes to providing a positive customer experience. While LMNT might work well for some people, such as athletes, I recommend Live it Up Vital Minerals to individuals looking for effective daily hydration. 

Here's how Vital Minerals outshines LMNT Electrolyte Drink Mix: 

• Features a balanced sodium-to-potassium ratio suited for daily hydration
• Contains 510mg of sodium, with the understanding that many Americans already have diets high in sodium
• Includes vitamin C, which supports immune function and heat tolerance, an often-overlooked factor in hydration
• Built on a coconut water powder base that provides naturally occurring electrolytes and trace minerals before any additional minerals are added

At less than $1 per serving, Vital Minerals is an affordable, effective option for your electrolyte needs.

Did You Know? Vitamin C is important not only for immune health but also to help the body combat heat stress. Supplementing with vitamin C can be especially helpful when exercising on a hot day.

LMNT FAQs

Is LMNT hydration good for you? 

Deciding if LMNT is good for you depends on your electrolyte intake goals and nutritional needs. For instance, if you're an athlete or frequently do endurance exercise, LMNT may help you adequately replenish sodium lost in sweat. However, daily users should be aware that the amount of sodium in LMNT (1,000mg) is nearly half of the highest recommended daily intake. 

Can you drink LMNT every day? 

Yes, you can drink LMNT every day. Before adding LMNT to your routine, just be aware of your sodium intake throughout the day, as LMNT contains 1,000mg of the 2,300mg maximum daily value noted by the FDA.  

What are the negatives of LMNT?

While many customers love LMNT, in some LMNT salt product info and reviews, others note that the electrolyte powder tastes too salty, is too expensive.

How much sugar is in LMNT? 

There are no added sugars in LMNT Electrolyte Drink Mix. LMNT only offers zero-sugar electrolyte powders.

Does Costco sell LMNT drinks? 

Yes, many Costco locations sell LMNT drinks. Check your local Costco to see if it sells LMNT and what flavors are included.

Is LMNT worth the price?

LMNT costs $1.30 per serving with a subscription and $1.50 as a one-time purchase. For people who need high sodium replacement, such as those on keto or low-carb diets, or those training in high heat, the formula may justify the premium. For everyday hydration, electrolyte powders with a more balanced electrolyte profile are available at a lower price point.

What is a good alternative to LMNT?

For everyday hydration, Live it Up Vital Minerals provides a more balanced electrolyte profile with vitamin C and a coconut water base at $1 per serving. For a low-sodium option, Ultima Replenisher contains 55 mg sodium with six electrolytes. For an oral rehydration formula with added sugar, Liquid I.V. uses a glucose-sodium cotransport approach. The right alternative depends on your hydration goals and activity level.
