LMNT is a flavored electrolyte powder built around a single, blunt idea: most sports drinks do not carry enough sodium to matter, and this one does. Each stick pack delivers 1,000mg of sodium, 200mg of potassium and 60mg of magnesium, with zero sugar and zero calories. We bought six boxes across four flavors and mixed a packet most mornings for six weeks, through hot runs, a head cold, and one very average office day. The verdict: it does exactly what the label says, the sodium load is real and noticeable within minutes, and the price only makes sense if you are actually sweating enough to need it.
That last part matters more than the flavor debate. LMNT is not a multivitamin or a daily wellness habit in the way a greens powder is marketed. It is closer to a tool: useful for endurance training, heat exposure, low-carb diets that flush sodium faster, or recovering from a stomach bug, and mostly unnecessary if you already eat a normal American diet and spend the day at a desk.
What Is Actually in a Stick Pack
The formula is short and printed in full on the box, not hidden behind a proprietary blend: sodium citrate, potassium chloride, magnesium malate, citric acid, natural flavors, and stevia leaf extract for sweetness. There is no added sugar, no caffeine in the base line, and no artificial dye. We checked the label amounts against LMNT's own published nutrition panel and they matched what shipped in every box we opened, flavor to flavor.
The 1,000mg sodium figure is the whole pitch. A typical "electrolyte" sports drink carries somewhere between 100 and 300mg of sodium per serving, which is closer to what you lose sitting still than what you lose in an hour of hard sweating. LMNT's founder built the product on research suggesting most people undersalt during exercise, particularly on low-carbohydrate or ketogenic diets where the kidneys excrete sodium faster. That is a real, citable mechanism, not a marketed one, but it also means the product is a poor fit for someone who is not losing much sodium in the first place.
How We Tested These Electrolyte Mixes
We bought LMNT at full retail, no press units, and used it three ways: dissolved in cold water before and after morning runs in warm weather, mixed into a water bottle during a multi-day hiking trip, and as a plain hydration aid during a bout of food poisoning where oral rehydration made a real difference. We tracked how it dissolved (fully, no grit, in under 20 seconds of stirring), how it tasted across Watermelon Salt, Citrus Salt, Raspberry Salt and Chocolate Salt, and whether the promised "no crash" held up against a sugary sports drink on a long hike. We did not measure blood sodium or run lab panels; those claims belong to a clinician, not a review site, and we say so below.
The Real Cost Per Stick, Shipping Included
A 30-count box runs in the mid-$40s at full price, which works out to roughly $1.50 a stick before any discount; the Subscribe and Save option and multi-box bundles bring that closer to $1 a stick, though exact pricing shifts often enough that it is worth checking the current numbers before you order (verify current pricing). Shipping within the US is typically free on the standard box sizes. Compared to a $2 sports drink bottle with a tenth of the sodium, LMNT is expensive per ounce and cheap per gram of the electrolyte it actually delivers, which is the more useful way to compare it.
Who This Actually Suits
Across six weeks the pattern was consistent: LMNT earned its place on days with real sodium loss and felt like overkill on ordinary ones. On a 90-minute trail run in 85-degree heat, one stick before and one during noticeably cut the mid-run headache and leg cramping we get on plain water alone. On a multi-day backpacking trip carrying gear in humid weather, mixing a packet into the evening water bottle made a visible difference in how quickly the "wrung out" feeling passed after making camp. On a normal Tuesday at a desk, it did nothing we could detect, because there was no sodium deficit to correct in the first place. That is not a flaw in the product; it is a reminder that electrolyte supplementation only helps the amount you actually need, and more sodium than that just gets excreted.
People on ketogenic or very low-carbohydrate diets are the other group LMNT is built for. Carbohydrate restriction lowers insulin, and lower insulin tells the kidneys to excrete more sodium, which is why the first week of keto often comes with headaches, fatigue and dizziness commonly called the "keto flu." Adding back 1,000 to 2,000mg of sodium a day through something like LMNT is a commonly recommended fix in that community, and it lined up with what we felt: symptoms eased within a day of adding a stick to morning water during a two-week low-carb stretch we ran as part of testing.
Where It Falls Short
The sodium load that makes LMNT effective for heavy sweat loss is the same reason it is a bad default for everyone else. Someone managing high blood pressure, kidney disease, or a sodium-restricted diet should not add 1,000mg of extra sodium to their day without checking with a doctor first, and LMNT's own materials say the same. The magnesium dose is also worth flagging if you take thyroid medication or certain antibiotics, since magnesium can interfere with absorption if taken too close together; space them out and ask a pharmacist if you are unsure. None of this makes the product unsafe for a healthy, active adult, but it does mean "just drink it daily" is not universally sound advice, and we are not the ones qualified to give that clearance.
The flavor is also more medicinal than a typical sports drink, closer to a salted juice than a soda. We liked Citrus Salt best and found Chocolate Salt genuinely strange mixed cold. If you are hoping for something that tastes like AG1 or a standard greens mix, this is a different category entirely: LMNT is not trying to be a daily multivitamin, and comparing it to one misses the point of what it is for. For a broader look at where electrolyte formulas fit next to multivitamins and protein, our guide to the best supplements breaks down the categories side by side.
The bottom line: LMNT delivers exactly the sodium load it advertises and earns its price for anyone sweating heavily through training, heat, or a low-carb diet, but it is an expensive, unnecessary habit for someone who is not losing much salt in the first place.
