LMNT vs AG1: One Job Done Well vs 75 Jobs Done Vaguely

Two opposite philosophies in a packet

LMNT is built on a narrow premise: if you lose a lot of sodium through sweat, you should replace it, and most sports drinks under-dose it while over-dosing sugar. One stick delivers roughly 1000 mg sodium, 200 mg potassium, and 60 mg magnesium, with zero sugar. That is the whole product. AG1 takes the opposite approach, packing vitamins, minerals, adaptogens, probiotics, and plant extracts into one daily scoop and positioning itself as foundational nutrition. A narrow product is easy to evaluate: either you have the problem it solves or you do not. A kitchen-sink product asks you to trust that 75 ingredients, most at undisclosed doses, are each doing something. That trust has to be earned, and it is not.

What the evidence actually supports

Electrolyte replacement during prolonged, heavy sweating is one of the better-supported ideas in sports nutrition. Sodium losses through sweat are real and measurable, and replacing fluid without sodium during long efforts in heat can leave you feeling worse. That makes LMNT's core use case, endurance training, hot manual work, and heavy sweaters, reasonably well grounded, even if specific claims about cramps remain debated. AG1's evidence picture is thinner. Some individual ingredients, like specific probiotics or vitamin D, have decent research at known doses. But research on the AG1 formula itself is limited and largely company-funded, and you cannot map outside studies onto a product that hides most of its doses. Well-supported ingredients at unknown doses is not well-supported nutrition.

Transparency: full label vs proprietary blends

This is where the comparison stops being close. LMNT prints every dose on the packet. You can check those numbers against published sweat-loss data, compare them to a homemade mix, and decide whether the format is worth the money. AG1 wraps most of its 75 ingredients inside proprietary blends, so you know the total grams per blend but not how much of any single ingredient you are getting. That matters because dose determines effect. An adaptogen at a tenth of a studied dose is marketing, not supplementation. Proprietary blends are legal and common, but on a science-first grading rubric they are a serious penalty: they make the product impossible to evaluate honestly, which is rarely an accident.

Price per verified benefit

AG1 runs about 99 dollars a month on subscription, among the most expensive daily supplements sold to healthy people. For that money you get a product whose doses you cannot verify and whose strongest defensible claim is that it works like an expensive multivitamin with extras. LMNT costs roughly 45 dollars for 30 sticks, about 1.50 per serving, and you only need it on days you sweat hard, so a box can last months. It is still expensive for what it is; salt, potassium, and magnesium cost pennies in bulk, and a DIY version is easy. But at least you can see exactly what you are paying for. Cost per verified benefit clearly favors LMNT.

Verdict: LMNT wins, but many people need neither

LMNT wins this comparison because it makes one narrow, checkable claim and backs it with a transparent label, while AG1 makes broad claims it structurally prevents you from verifying. But a win here is conditional. If you are mostly sedentary, work indoors, and eat a reasonably normal diet, you likely get plenty of sodium already and need neither product; extra sodium can be actively unwise with high blood pressure or kidney concerns. AG1 buyers would usually do better with food, a basic multivitamin if their clinician suggests one, and the savings. Talk to your doctor or pharmacist before adding either, especially a high-sodium product, and treat both as tools for specific situations, not daily insurance.
