Runners go through electrolyte mix fast, and buying it box by box gets pricey. This list compares brands that ship drink mix to your door on a schedule, so you can pick one that fits your runs and your wallet.
Every brand here sells a powder or tablet you mix into water, and each one offers some form of repeat delivery with a discount. The comparison looks at simple things. How much sodium each serving has, because a salty sweater on a long run needs a lot more than someone doing an easy 5K. How much sugar, since some mixes also give you fuel and some are zero sugar. Then the plan itself: how big the discount is, how often it ships, whether shipping is free, and how easy it is to skip or cancel. Price per serving counts too.
The order of the electrolyte mix subscriptions for runners on this page comes from community votes, not from the editors. If a brand works for you, or lets you down, vote and leave a review. Each card lists pros and cons, and reader reviews show how the product and the subscription hold up after a few months.
LMNT is a zero sugar electrolyte mix sold mostly in stick packs. It is known for a very salty formula: each stick has 1000 mg of sodium, 200 mg of potassium and 60 mg of magnesium. A box of 30 sticks costs about $45, and a 12 stick variety pack about $20 as a one-time buy. With the monthly subscription the variety pack drops to about $18. Flavors range from Citrus Salt and Watermelon Salt to a Raw, unflavored option.
This mix makes the most sense for heavy sweaters, hot weather runners and people on low carb diets. It gives no fuel at all, so on long runs you still need gels or food for energy. Some people find the taste too salty for easy days and use half a stick. Subscriptions can be paused or changed, and support works by email and chat on weekdays.
Liquid I.V. started in 2012 in Marina Del Rey, California, and is now owned by Unilever. Its main product is the Hydration Multiplier, a stick pack built around what the brand calls Cellular Transport Technology, a mix of sodium, glucose and potassium. There are also sugar-free, energy and immune support lines. You can find it in most US grocery stores and pharmacies.
The subscription is one of the biggest discounts in this niche: 30% off every order, with delivery every one to three months. You can swap flavors, change dates or cancel anytime, and you get a reminder before each shipment. For runners it works well as a daily or post-run drink. The classic sticks have a fair amount of sugar, and the sodium is lower than in endurance brands, so salty sweaters on long runs may need more.
Nuun comes from Seattle and is best known for fizzy tablets that dissolve in a bottle of water. A tube fits in a pocket or race belt, which is why many runners carry it. The range covers Nuun Sport for daily training, Nuun Endurance with carbs for long efforts, plus immunity and rest lines. Tablets are low in calories and less sweet than most powders.
The subscription gives 15% off every recurring order and free shipping on all plan orders. Subscribers can edit their box contents and also earn points in the Nuun+ rewards program. There is a 60-day satisfaction guarantee, handled by phone or web form. Tablets are cheap per serving, but sodium per tab is modest, so heavy sweaters on hot marathons usually need a stronger product next to it.
Skratch Labs is based in Boulder, Colorado, and grew out of work with pro cycling teams. Its Sport Hydration Drink Mix uses real fruit for flavor and has a light taste, so it is easy to drink for hours. The line also includes an Unsweetened Hydration mix with no sugar and a Super High Carb drink mix for long races. Products are gluten-free, dairy-free, vegan and kosher.
On the brand site, subscribers get an ongoing discount on repeat orders, and US shipping is free on orders over $49. The Loyalty Lab program adds 10 points for every dollar spent. Skratch fits runners who want a mild mix that does not upset the stomach. The regular mix has fewer carbs than dedicated fuel drinks, so for marathons many pair it with gels or switch to the high carb version.
Tailwind Nutrition is a Durango, Colorado brand popular with trail and ultra runners. Its Endurance Fuel is an all-in-one drink: calories, electrolytes and water in one bottle, so many runners skip gels. The electrolyte blend includes sodium, potassium, magnesium and calcium. It comes in single sachets, 50-serving bags and caffeinated flavors. Tailwind is the official fuel of the Hardrock 100.
This mix suits long runs, ultras and hot trail days where solid food gets hard to eat. For short runs it is too much, since each serving carries real calories. Big bags are the cheapest way to buy it, and the brand offers free shipping over $59. Repeat buyers can set up regular orders on the site. The taste is mild, but some runners get tired of it after many hours.
Precision Fuel & Hydration was founded in the UK by sports scientist Andy Blow and has a US store with prices in dollars. Its idea is simple: people sweat out very different amounts of salt, so the mixes come in different strengths. PH 1500, the strongest, has 1500 mg of sodium per liter, about three times a regular sports drink. There are tablets, drink mix packets and PF 60 carb drink mix with 60 g of carbs and 1000 mg of sodium per liter.
A free online sweat test helps pick the right strength, which is handy for runners who cramp late in races. The brand says it rarely runs sales. Instead, loyal buyers earn points toward 10%, 15% and finally a lifetime 20% discount. That makes it better for steady long-term buyers than for bargain hunters. Low strength options exist for light sweaters.
DripDrop is an oral rehydration solution in powder form, created by a doctor who worked on dehydration in disaster zones. The formula follows medical rehydration logic: a balanced ratio of sodium, potassium and sugar for fast absorption. Sticks are sized for 8 oz or larger servings, and there are Zero Sugar versions along with bold flavor packs.
The Subscribe & Save plan gives 25% off every order and free shipping. For example, a 32-count box drops from $35.99 to $26.99. You choose delivery every 4, 6, 8, 12 or 24 weeks and can change or cancel up to 24 hours before shipment. Runners use it mostly after hot long runs or races when they feel wiped out. The regular version has sugar and a strong taste, so it is less pleasant as an all-day drink.
Ultima Replenisher is a sugar-free electrolyte powder from Ultima Health Products, a company based in Bernardsville, New Jersey. It has zero calories, uses plant-based flavors and colors, and is sold in tubs and stick packs. You can also find it at Walmart, Target and iHerb.
On the brand site the subscription gives 10% off, with delivery every 30, 60 or 90 days and cancel anytime. There is a 60-day satisfaction guarantee, and customer care answers by phone on weekdays from 9am to 5pm ET. The mix fits runners who want a clean daily drink without sugar or a salty taste. The sodium level is low, so it is a poor choice on its own for hot long runs or heavy sweaters.
Cure Hydration was founded in 2017 in New York City. Its drink mix uses organic coconut water and pink Himalayan salt, with no added sugar, and the formula is based on the WHO oral rehydration solution. There are Hydrate and Energy lines. A bag of 14 packs costs about $20.99 for Hydrate and $24.99 for Energy as a one-time buy.
The subscription starts at 15% off, and bundling more flavors raises the discount up to 32% per delivery. Orders ship every 28 days by default, and you can move the ship date. Cure suits runners who want a natural ingredient list and a mild taste for daily use. The 14 pack bags run out fast if you drink it every day, and the sodium is not high enough for very salty sweaters on long runs.
SaltStick is made by Toker Engineering and became known among runners for electrolyte capsules and chewable FastChews. Its DrinkMix is a sugar-free powder with no artificial sweeteners, Informed Choice certified, keto-friendly and vegan. It comes in single-serve stick packs and 40-serving tubs, and a tub can go straight into a 5-gallon water cooler for a team or race aid station.
For repeat delivery, SaltStick products are available through Amazon Subscribe & Save, with 10% off now and up to 15% on bigger orders. That is handy for runners who already use Amazon. The mix is not very sweet, which many like on hot days. It has no carbs, so long runs still need fuel from gels or food. Some runners pair DrinkMix with capsules in races for extra sodium.
