The Best Clean Electrolyte Powders, Label by Label

Most people reading this don’t need an electrolyte powder most days. Americans already eat more than 3,300 mg of sodium a day, and for a desk job and a normal workout, water does the job.

But if you train long, sweat heavily, work in heat, or you’re the person who gets the stomach bug, the right powder is a useful thing to own. The problem is that the aisle is full of products whose labels tell you very little about what matters.

If you want the short version: DripDrop is the one we’d keep in the cupboard, built on the oral rehydration model and listed at NSF Certified for Sport. If you’re watching sodium or money, Ultima Replenisher is $0.73 a serving and barely salty at all.

Here’s how we picked:

• Sodium that matches a real use. Every entry states its sodium per serving, because a 55 mg mix and a 1,000 mg mix are different products for different people. We compared the labels here.
• A sweetener we can defend. Real sugar where it has a job, stevia or nothing where it doesn’t. No sucralose-sweetened powders and no erythritol, for the reasons laid out here.
• Testing and record. A named third-party program where one exists, checked at the issuer, and a search of California’s Prop 65 notices, recalls and class actions for every brand. Where we found something, the entry says so.
• Ownership named. Three picks are founder-led, one is venture-backed, one is private equity owned, and one has an investor history we couldn’t fully trace.

DripDrop: the rehydration formula with a certifier

Best for: illness, heat, and anyone who wants one powder in the cupboard | Price: around $36 | Start with: DripDrop Original, Lemon Lime, 32 sticks, $35.99 | Ownership: investor-backed; current controlling owner not confirmed

This is the one closest to what doctors actually reach for. DripDrop says it’s built on oral rehydration science, and the label reflects it: 330 mg of sodium, 180 mg of potassium and 7 g of sugar per stick in 8 oz, which works out to roughly 1,390 mg of sodium per liter. That’s in the neighborhood of the WHO’s rehydration formula, where sugar is doing a job rather than flavoring the drink.

It’s also the only full product line here we found listed at NSF Certified for Sport, with the original flavors, Zero Sugar and other formats all on the register. The 32-stick box is $35.99, about $1.12 a serving.

The record has two things to know. In 2022, DripDrop received three Prop 65 notices over lead and mercury, which were settled that December. And a proposed class action over artificial flavors, Helems v. Drip Drop Hydration, is listed as pending. On ownership, the company raised a $5.6 million round in 2014, and while business databases now describe it as acquired or merged, we couldn’t find who owns it today.

Skip it if: you want zero sugar. That sugar is part of how the formula works.

LMNT: a gram of sodium, and a lawsuit to know about

Best for: heavy, salty sweaters who want zero sugar | Price: around $45 | Start with: Recharge Raw (unflavored), 30 sticks, $45 | Ownership: founder-led, with crowdfunded investment

LMNT is the brand most people mean when they say clean electrolytes. Each stick carries 1,000 mg of sodium, 200 mg of potassium, 60 mg of magnesium and no sugar, at $45 for 30 sticks. That’s a serious dose, about 43% of the daily sodium limit, and the right one for a long, hot session rather than a desk.

Here’s what the marketing won’t tell you. In 2025, three proposed class actions were filed alleging that LMNT’s flavored sticks contain roughly 300 to 450 mg of maltodextrin listed under “natural flavors”, which plaintiffs argue conflicts with its “all natural” and keto positioning, as reported by NutraIngredients. The most recent report we found said the cases were in discovery. These are allegations, not findings.

That’s why we’d start with Raw. It’s the unflavored version, so it skips the “natural flavors” at the center of the lawsuits, and it tastes exactly like salt water. We didn’t find LMNT on NSF’s register, and the company is founder-led, having raised money through Reg CF crowdfunding in 2021 and 2022.

Skip it if: you’re not sweating heavily. A gram of sodium you don’t need is just a gram of sodium.

Precision Fuel & Hydration: built for long, hot days

Best for: marathons, ultras, long rides and anyone who’s measured their sweat | Price: around $14 | Start with: PH 1500 drink mix, 8 packets, $13.99 | Ownership: founder-owned

Precision is a UK sports-science company that sells sodium by the dose rather than by the vibe. Its PH 1500 drink mix delivers 1,500 mg of sodium per 32 oz, which is 750 mg per packet mixed into 16 oz, with 15 g of sugar and no artificial sweeteners. It’s built for people who sweat salt for hours.

The testing comes with a wrinkle. Precision’s PH tablets are listed at NSF Certified for Sport, but the drink mix isn’t on that list, and the tablets are sweetened with sucralose. The brand states that the drink mix carries Informed Sport certification, which we couldn’t check at the register. So you choose: the certified tablet with sucralose, or the sugar-sweetened mix with a brand-stated certification.

Ownership is about as clear as it gets. UK company filings show the business is held by its two founders, Andy Blow and Jonny Tye, through a holding company set up in 2026.

Skip it if: your workouts are under 90 minutes. This is more sodium than most sessions need.

Skratch Labs: sugar and salt, nothing else

Best for: training sessions where you want fuel and fluid in one bottle | Price: around $24 | Start with: Hydration Sport Drink Mix, Lemon + Lime, 20 servings, $23.95 | Ownership: founder-led

Skratch Labs is still led by its founder, Allen Lim, and its label reads like a kitchen recipe. The Hydration Sport Drink Mix uses cane sugar and dextrose with 400 mg of sodium per serving, and no stevia, no sucralose, nothing else sweet. At 17 to 19 g of sugar a serving, it’s fuel as much as hydration, which is the point on a long ride and the problem on a lazy afternoon.

The record needs more than a sentence, because it includes the exact flavor we’d start you on. A 2022 Prop 65 notice named the Lemon + Lime Hydration Drink Mix over mercury, and a companion notice named the Summer Peach and Matcha flavors over lead. Both were settled in 2023, along with a later PFOA notice, for $118,500 plus a court order capping lead in the products it sells in California at 0.5 micrograms a day. That’s resolved, and the cap is a real commitment. We’d still rather you heard it from us.

We didn’t find Skratch on NSF’s register, and found no acquisition. Startup databases list a couple of outside investors, which we couldn’t confirm.

Skip it if: you want electrolytes without the calories.

Ultima Replenisher: the low-sodium option

Best for: people watching sodium who still want potassium and magnesium | Price: around $22 | Start with: Lemonade, 30-serving canister, $21.99 | Ownership: owned by WM Partners, a private equity firm (since 2019)

This one is honest about being different. Ultima carries just 55 mg of sodium per serving, with 250 mg of potassium and 100 mg of magnesium, sweetened with stevia and no sugar. At $21.99 for 30 servings, it’s the cheapest per serving here.

That low sodium is the whole reason to buy it, and the whole reason not to. For someone with high blood pressure who wants a flavored drink with some potassium, it fits. For a heavy sweater after a long run, it barely replaces anything, and you’d want something from the top of this list instead.

Ultima is owned by WM Partners, a private equity firm, through a 2019 deal. We found no recalls, warning letters or Prop 65 notices naming it, and no listing on NSF’s register.

Skip it if: you’re replacing sweat losses. 55 mg won’t do it.

Cure Hydration: coconut water powder, sweetened with stevia

Best for: people who want a gentler, plant-based mix for moderate days | Price: around $24 | Start with: Lemonade, 14 packets, $23.99 | Ownership: venture-backed (Lerer Hippeau led its 2023 Series A)

Cure builds its mix on coconut water powder, which shows in the numbers: 240 mg of sodium, 310 mg of potassium and 4 g of sugar per packet, none of it added, sweetened with organic stevia and monk fruit. It sits between the very salty and the barely salty, which suits a moderate workout or a hot day.

At $23.99 for 14 packets, it’s on the pricier side per serving. Monk fruit carries a small caveat too: it’s GRAS in the US, while Europe’s food safety panel found the data insufficient to conclude on it in 2019. We found no recalls, warning letters or Prop 65 notices naming Cure, and no NSF listing. The company raised a $5.6 million Series A led by Lerer Hippeau in 2023.

Skip it if: you’re a heavy sweater. Like coconut water itself, it’s lighter on sodium than a long session needs.

Red flags on an electrolyte label

Start with the sodium you can’t see on the front. Mixes in this category range from 55 mg to 1,000 mg a serving, and the front of the box rarely tells you which one you’re holding. Compare them here before you assume more is better.

Then the sweetener line. Sucralose has new lab findings about a breakdown product, erythritol has been linked to platelet effects in a small trial, and sugar is there for a reason in some mixes and for taste in others. We went through each one.

“Natural flavors” deserves a second look in this category specifically, because it’s the exact phrase at the center of the LMNT lawsuits. Unflavored versions remove the question.

And remember that powders are processed, concentrated products. California’s Prop 65 system has named several electrolyte powders over lead in the past two years, which is the same story we found in protein powder and collagen. A named certifier like NSF Certified for Sport is the best protection available.

What we left off, and why

Redmond Re-Lyte is the hardest omission, because it’s a family-founded company with a clean-looking label. But in 2025 it received two Prop 65 notices alleging lead, one naming Re-Lyte Hydration and its retailer and one naming a pre-workout sample pack, and in June 2026 an advocacy group’s own testing described the unflavored Re-Lyte as the highest-lead electrolyte powder it had tested. Notices are allegations and advocacy testing isn’t a regulator’s finding, but together they’re enough for us to wait.

The big names are mostly owned by the biggest food and beverage companies. Liquid I.V. has belonged to Unilever since 2020, and carries 11 g of sugar a stick. Nuun was bought by Nestlé Health Science in 2021. BodyArmor is fully owned by Coca-Cola after a 2021 deal.

Pedialyte, made by Abbott, deserves a fairer word. It’s a well-formulated oral rehydration product, and if you’re sick and it’s what the pharmacy has, buy it. It’s off the list for ownership, not for the formula.

How to actually choose one

Start with the question most roundups skip: do you need one? If you haven’t read the honest answer, it should only take a few minutes and might save you $40 a month.

If you do, match the powder to the job. For illness or heat, DripDrop. For long training with fuel, Skratch or Precision’s drink mix. For a heavy sweater who wants no sugar, LMNT Raw. For moderate days, Cure. For flavored water with potassium and almost no salt, Ultima.

And keep a box of the right one for the day you need it, rather than a daily habit you don’t. The most useful electrolyte powder in most homes is the one still in the cupboard when the stomach bug arrives.

Frequently asked questions

What is the cleanest electrolyte powder?

It depends on what clean means to you. For no sugar and no sweeteners at all, LMNT Raw is unflavored and unsweetened. For a third-party certified product, DripDrop is listed at NSF Certified for Sport. For a sugar-only formula with no artificial sweeteners, Skratch Labs and Precision’s PH 1500 drink mix both qualify.

Which electrolyte powder has the most sodium?

Of our picks, LMNT carries the most at 1,000 mg per stick, followed by Precision’s PH 1500 drink mix at 750 mg per packet. Ultima Replenisher carries the least at 55 mg. Check the nutrition panel, because the front of the box rarely says.

Is LMNT safe?

Its label is simple: 1,000 mg of sodium, potassium, magnesium and no sugar. In 2025, three proposed class actions alleged its flavored sticks contain maltodextrin listed as natural flavors, which hasn’t been decided in court. The unflavored Raw version skips the flavorings at issue. People with high blood pressure or kidney disease should check with a doctor before using any high-sodium mix daily.

Are electrolyte powders third-party tested?

Some are. DripDrop’s line and Precision Fuel & Hydration’s tablets are listed at NSF Certified for Sport, which you can check on NSF’s own site. Many popular brands make testing claims without a named program, so look for the certifier’s name and check its register.

Do electrolyte powders contain lead?

Some have been named in California Prop 65 notices alleging lead, including Redmond Re-Lyte in 2025 and several smaller brands. A notice is an allegation, not a confirmed finding. Choosing a product with a named third-party certification is the most practical safeguard.

Is Liquid I.V. a good electrolyte drink?

It carries 500 mg of sodium and 11 g of sugar per stick, and it’s owned by Unilever. It works as a hydration drink, though the sugar is more than you’d want for daily sipping. We left it off for ownership and sugar rather than safety.
