LMNT is a sugar-free electrolyte drink mix sold in single-serve stick packs that you stir into water. Each packet delivers 1,000 mg of sodium, 200 mg of potassium, and 60 mg of magnesium, a ratio that’s intentionally sodium-heavy compared to mainstream sports drinks. The brand was built around the idea that most people, especially those eating whole foods or following low-carb diets, aren’t getting enough sodium from food alone.
What’s in a Packet
The formula is deliberately simple. The electrolytes come from three mineral compounds: sodium chloride (table salt), potassium chloride, and magnesium malate. Flavored versions use natural fruit flavors and stevia leaf extract as a sweetener. There’s no sugar, no artificial colors, and no anti-caking agents. A few varieties, like Chocolate Salt and Chocolate Caramel, also contain cocoa powder.
The standout number is that 1,000 mg of sodium. For context, a 12-ounce serving of Gatorade contains about 160 mg of sodium. When you mix one LMNT packet into 16 ounces of water (as recommended), you’re getting roughly six times more sodium than the same volume of a standard sports drink. That’s the core of the product’s identity: it’s a salt-forward electrolyte supplement, not a lightly flavored hydration drink.
Why So Much Sodium
LMNT’s formula reflects a specific philosophy about sodium needs. The brand points to several scenarios where people lose or consume less sodium than their bodies require. Athletes training in hot, humid conditions can lose several grams of sodium through sweat in a single session. People who’ve cut out processed food, which accounts for roughly 70% of the average American’s sodium intake, often see their sodium levels drop significantly without realizing it. And low-carb or ketogenic diets create a separate problem: when insulin levels stay low, the kidneys flush sodium more rapidly, increasing the body’s baseline need.
The brand’s co-founder, Robb Wolf, has described the origin story in personal terms. He’d been eating a low-carb, whole food diet for years but felt something was off. Working with coaches, he landed on a simple fix: more salt. Existing electrolyte products were too high in sugar and too low in actual minerals, so he and his team started making their own mixes at home before eventually turning it into a company.
LMNT cites research suggesting that optimal daily sodium intake for most people falls between 4,000 and 6,000 mg, a range higher than the 2,300 mg ceiling commonly recommended by public health organizations. This is where the product sits in a genuine scientific debate. The World Health Organization recommends keeping sodium below 2,000 mg per day, and the American Heart Association suggests less than 1,500 mg for people with elevated blood pressure. LMNT’s position aligns with newer observational studies that have found a J-shaped curve for sodium and health outcomes, where both very low and very high intakes carry risks, but this remains contested among researchers.
Who It’s Designed For
The product was originally formulated for people on ketogenic, low-carb, or intermittent fasting protocols. All three of these dietary approaches reduce insulin levels, which triggers the kidneys to excrete more sodium and water. The result is what keto dieters often call “keto flu,” a cluster of symptoms including headaches, fatigue, muscle cramps, and brain fog that are largely caused by electrolyte depletion. Because LMNT contains zero sugar and zero carbs, it won’t interfere with ketosis or break a fast.
The audience has expanded well beyond keto circles, though. Endurance athletes, people who work outdoors in heat, and anyone who sweats heavily during exercise are common users. If you’re someone who drinks plenty of water but still feels sluggish, crampy, or lightheaded, sodium depletion is a reasonable thing to investigate, and LMNT is built to address that specific gap.
How People Use It
Most users mix one stick pack into 16 ounces of water and drink it before or during a workout, first thing in the morning, or during a fasting window. The brand says many customers find one to two packets per day works well, depending on activity level, climate, and diet. There’s no hard daily limit prescribed on the packaging, because sodium needs vary dramatically from person to person. A desk worker in a cool office and a construction worker in July have completely different requirements.
Flavors range from citrus (Citrus Salt, Grapefruit, Orange) to fruit (Watermelon, Mango Chili, Pineapple) to dessert-inspired options (Chocolate Salt, Chocolate Caramel). There’s also an unflavored “Raw” version that contains only the three mineral salts with nothing else, which you can add to coffee, soup, or any beverage without changing its taste much. LMNT also sells a sparkling canned version for people who prefer something ready to drink.
How It Compares to Other Electrolyte Drinks
The easiest way to understand LMNT is to compare it to what’s already in most people’s fridges. Traditional sports drinks like Gatorade were designed for a different purpose: providing quick-burning carbohydrates alongside modest electrolytes during athletic performance. A 12-ounce Gatorade has about 160 mg of sodium and around 21 grams of sugar. LMNT has over six times the sodium and no sugar at all. These products are solving different problems.
Hydration multiplier products like Liquid IV sit somewhere in between. They contain more electrolytes than Gatorade but still include sugar (typically 11 grams per serving) because they use a glucose-sodium co-transport mechanism to speed absorption. LMNT skips this approach entirely, prioritizing mineral content over absorption speed and keeping the formula compatible with sugar-free diets.
The tradeoff is taste. Dissolving 1,000 mg of sodium into 16 ounces of water produces a noticeably salty drink. The stevia and natural flavors soften this, but if you’re expecting something that tastes like fruit juice, you’ll need to adjust your expectations. Many users report that the saltiness becomes pleasant once their body adapts, particularly if they were genuinely sodium-depleted.
Sodium Intake and Health Risks
The elephant in the room with any high-sodium product is blood pressure. Excess dietary sodium is an established risk factor for hypertension, and hypertension is a leading driver of heart disease, stroke, and kidney damage. The American Heart Association has recommended that people with elevated blood pressure keep sodium below 1,500 mg per day, or at minimum reduce their current intake by 1,000 mg. A single LMNT packet would meet or exceed that entire daily limit on its own.
This doesn’t mean LMNT is dangerous for everyone. Sodium sensitivity varies considerably between individuals. People with healthy kidney function, normal blood pressure, and high activity levels process sodium differently than someone with existing cardiovascular disease. But if you have high blood pressure, kidney problems, or heart disease, adding 1,000 to 2,000 mg of supplemental sodium to your diet is something to discuss with your doctor before starting. The product fills a real gap for people who are genuinely under-salted, but not everyone falls into that category, and more sodium isn’t automatically better.
It’s also worth noting the potassium numbers. LMNT provides 200 mg of potassium per packet, while the WHO recommends at least 3,510 mg of potassium daily, and the American Heart Association suggests 3,500 to 5,000 mg. Potassium helps counterbalance sodium’s effect on blood pressure, so the ratio in LMNT is heavily tilted toward sodium. If you’re using LMNT regularly, making sure the rest of your diet includes potassium-rich foods like avocados, bananas, potatoes, and leafy greens becomes more important.
