9 Best Drinks for Stomach Flu | Electrolytes That Stay Down

A doctor-built formula with three times the electrolytes of a sports drink and half the sugar.

DripDrop is the pick for a household that already knows what an oral rehydration solution is (a drink that replaces the water and salts you lose) and wants the balance dialed in. The maker claims three times the electrolytes of a leading sports drink with half the sugar. Mixing is simple: one packet into 8 oz of water, which is a smaller glass than most sticks call for, so a single bottle of water stretches further. There are 16 packets in the pouch across Watermelon, Berry, Lemon, and Orange.

Four flavors in one pouch is a real advantage when taste turns on you mid-illness. Rotating between them keeps you drinking when a single flavor would have worn out its welcome. The ingredient list is kept clean too — non-GMO, gluten free, vegan, soy-free, dairy-free, and kosher — plus potassium, magnesium, zinc, and vitamin C. That combination is part of why this one has stuck around in so many kitchens.

The blend is where owners keep coming back. The taste and the effectiveness are the two things buyers talk about most, and the feedback runs deep — 4.6 stars across 50,000+ ratings, the widest pool of experience on this entire list. What the reviews describe is hydration that shows up fast, with a flavor that doesn’t linger or leave an aftertaste. The honest catch is the sugar content: it’s lower than a sports drink but it isn’t zero, and the cost per packet sits above the budget sticks. Some buyers also find it sweet enough to want to water it down a little.

Five fruit flavors, zero sugar, and a mix that goes down like flavored water.

If your problem is that sweet drinks turn your stomach, this is the box that solves it. Ultima sweetens with organic stevia leaf extract instead of sugar, so there’s no heavy syrupy finish to push back on. You get 20 stickpacks in the box — four of each flavor across Lemonade, Grape, Raspberry, Cherry Pomegranate, and Orange — which lets you find the one that sits best before you commit to a larger size. Each stickpack dissolves into 16 ounces of water, and the maker suggests adding ice after you stir for a colder, easier drink.

The formula covers all six electrolytes — magnesium, calcium, potassium, chloride, sodium, and phosphorus — plus vitamin C and zinc. That’s a broader mineral spread than you get from the simpler three-electrolyte mixes elsewhere on this list. It’s also gluten free, sugar free, zero calorie, vegan, keto friendly, and non-GMO certified, so it fits diets that rule out most sweetened drinks. The scoop of sodium here is on the lighter side, which makes it an easy everyday sip rather than a heavy hitter for intense sweating.

Two things stand out in the feedback: taste and effectiveness, and the volume of that feedback is enormous — 4.6 stars across 20,000+ ratings. Buyers keep describing the fruit flavors as crisp and free of any artificial aftertaste. The one item to know before you buy is dissolvability, which gets mixed reactions — some find it mixes perfectly, others say it needs more stirring to fully break down. A quick extra shake handles it. On the value side, opinions split, with the larger bulk formats drawing a better reception than the variety pack.

Same trusted Pedialyte name, minus the sugar, in a single gentle strawberry flavor.

For anyone who wants the Pedialyte name without the sugar, this is the box. You get 24 powder packets in one Berry Frost strawberry blend, all built on three key electrolytes: sodium, chloride, and potassium. It’s free of gluten and artificial colors, which keeps the ingredient list short and easy to scan when you’re not feeling well. Because it’s zero sugar and low in calories, it sidesteps the concern that a sweet formula can pull fluid the wrong way during a sensitive stomach stretch.

There’s a real advantage to the single-flavor approach: you know exactly what you’re getting every time. Some people find that a variety box runs out of the one flavor they actually like, leaving the rest untouched. This carton avoids that entirely. The packets also travel well — light enough to tuck into a bag or leave in the car for the day it’s needed.

The flavor is the star here, and the formula’s the part that earns trust. Owners describe the Berry Frost taste as present but not overly sweet, which keeps it drinkable when your appetite is gone. Buyers also report it dissolves well and helps with dehydration, muscle cramps, and dizziness. What you give up for the zero-sugar build is the faster absorption that a touch of sugar can provide; if you’re replenishing after hard exercise rather than illness, a lightly sweetened formula may work faster for you.

Turns a plain bottle of water into something you actually want to drink when nothing sounds good.

BODYARMOR positions this squarely at the active crowd, and the selling angle is the taste. Each stick is 15 calories with zero sugar and no artificial sweeteners, flavors, or dyes — three things a lot of people want out of a drink when they’re already feeling off. What separates it from the other sugar-free options is the base: it’s made with real coconut water powder, which gives it a natural sweetness rather than a synthetic one. You get 15 sticks in the pack across Tropical Punch, Strawberry Kiwi, and Lemon Lime.

Beyond hydration, the formula adds vitamins B and C plus zinc for immune support. The pack is small and light at 5.2 x 4.5 x 2 inches and 4.8 ounces, so it travels easily in a bag or a carry-on. That portability is a big part of the pitch here, since the whole point is having it ready when you need it rather than hunting for a store.

Taste carries this one in the feedback, with buyers pointing to the natural sweetness from the coconut water powder as the reason it doesn’t taste like a chemistry experiment. The convenience angle lands too — it’s described as a travel-day lifesaver. The one thing to go in knowing is that value divides opinion: some buyers think the cost per stick runs high for what’s in the pack, and a couple would prefer a larger container to cut down on waste and cost. The flavors also don’t perfectly match the bottled versions, so don’t expect an exact replica.

Forty sticks of serious sodium for the days you’ve been sweating hard and losing a lot.

ZestLytes is the go-to when you’ve been sweating hard for hours — a long outdoor shift, an intense session, or a stretch of heat that’s left you drained. Each stick carries 590 mg of sodium, along with 27 mg of magnesium and five performance vitamins, aimed at replacing what you lose during one to two hours of high-intensity effort. The maker says the sodium, potassium, and chloride levels closely match the balance used in oral rehydration solutions. You get 40 sticks in the pack across four salty fruit flavors: raspberry, watermelon, lemon, and orange.

The standout here is the math of the package itself. Forty individual sticks is by far the most servings of any powder on this list, and the per-serving toll lands in the friendliest range of the group. Buyers single out the value more than anything else — it’s the number-one thing praised by owners. Each stick mixes into 16 to 32 ounces of water, so you can dilute it to your taste, and the four-flavor spread keeps a long supply from getting boring.

Because the sodium runs high, the honest caveat is right there in the maker’s own guidance: if you’re not sweating heavily, this can taste too salty for casual sipping. For a queasy stomach where you’re losing fluids fast, the higher sodium is exactly what you want. Just don’t hand it to someone who’s merely thirsty.

Seven electrolytes and five vitamins in a grapefruit-forward stick that fits keto and vegan diets.

Venture Pal packs more into each stick than most of its neighbors — seven key electrolytes and five vitamins, including vitamin C and a B-vitamin range from B3 through B12. Each serving carries 400 mg of sodium and is sweetened with nothing at all, since the formula is completely sugar-free. It’s also keto-friendly and vegan, so it slots into diets that rule out most flavored drinks. The natural-flavor variety pack leans on grapefruit, which buyers name as the favorite again and again, and each stick dissolves into 16 ounces of water or more if you want it milder.

What makes this one worth flagging is how much it squeezes into a tiny packet without sugar. Compared with a tablet like the ginger-lime pick further down, this is a far smaller item to carry — the packet dimensions of 6.5 x 0.75 x 8.27 inches for the box against 1.34 x 1.34 x 3.4 inches for a single tube of tablets, a difference of many times over. For a backpack or a travel kit, that compactness is a genuine win. The maker also backs it with a no-return refund policy, even if the product’s been used, which takes some of the risk out of trying a new flavor.

The grapefruit taste is what buyers bring up most, and it’s praised as clean and refreshing rather than candy-sweet. Sugar content gets its own nods too, with several noting how well it fits a low-sugar routine. Worth knowing: with 400 mg of sodium per stick, it’s not built for anyone on a low-sodium diet, and a few palates find the salt level noticeable if they aren’t a salt fan. skip it if your taste runs sweet — the formula doesn’t hide its sodium.

A ginger-lime tablet for people who want their hydration to taste like something refreshing, not salty.

This one’s for the drinker with a sensitive stomach who finds sweet electrolyte mixes hard to keep down. Drinklits builds its tablet around organic ginger root with a hit of lime, so the flavor is bright and crisp rather than cloying. Each tube holds 10 effervescent tablets with 0 grams of sugar, and the tablets are gluten-free, non-GMO, vegan, kosher, and dairy-free, so they fit nearly any diet. Drop one into a glass of water and it fizzes apart on its own — no powder, no clumps, no stirring.

The electrolyte load is where this one plays differently. It’s built with vitamins rather than a heavy mineral hit: each serving carries 20% of the daily value of vitamin C, B1, B6, and B12, plus 20% magnesium, 10% sodium, 4% chloride, and 2% potassium. That lighter sodium profile is exactly why it goes down so easily, and why it isn’t the pick for replacing heavy sweat losses. What it does deliver is a clean base for daily hydration plus a tablet that travels flat and light — a single tube measures just 1.34 x 1.34 x 3.4 inches.

The one thing buyers mention over and over is the taste — the true ginger flavor that’s present without being overwhelming, plus the crisp lime finish. Digestibility and the ingredient list get their own share of praise, which is fitting for a product whose whole pitch is a gentler sip. The catch is the low sodium: if you’re trying to replace a lot of salt after a workout or a long, hot day, a 10% daily value won’t get you there. And the serving strength runs strong, so one tablet per 16 ounces of water can taste intense — most find it better diluted into 20 to 24 ounces.

The unflavored workhorse you can hide in juice — or use to dilute a sweeter drink.

Good Sense is the pick for anyone who needs hydration to disappear into whatever the drinker will actually swallow. It comes unflavored and ready to drink, so there’s nothing to mix and nothing to taste — you can stir it straight into juice or another drink. The formula is built to replace fluids, zinc, and electrolytes, and it’s made for mild to moderate fluid loss from causes as common as vomiting, diarrhea, intense exercise, heat exhaustion, and travel. Each liter delivers 45 mEq sodium, 20 mEq potassium, and 35 mEq chloride, and the pack holds six 33.8 fl oz bottles.

Unflavored is the entire point here. If a child or a picky adult refuses anything that tastes medicinal, this lets you control the flavor yourself — mix it into apple juice or pineapple juice and it disappears. It also works as a base to dilute a sweeter flavored drink, which lets you take in the electrolytes without the full sugar load. The pack is also made for both kids and adults, so one carton covers the whole household.

The value is what buyers talk about most — it’s described as doing the same job as the big name brand for a fraction of the cost, and buyers report it works just as well. The one honest trade-off is the taste: it gets mixed reactions, with some loving that it’s neutral and others finding it unpleasant on its own. That’s the nature of an unflavored solution — it’s a mixer, not a drink. Used the way it’s designed, stirred into something with flavor, it earns its keep. One more note straight from the listing: because the bottles can be affected by heat or sunlight, plan to be around when the package arrives.
