Mortal Hydration: Reviews, Sugar, and a Strong Alternative

If you've raced an Ironman in the last couple of years, you've seen the neon cups. Mortal Hydration took over the aid stations, pushed Gatorade Endurance off the course, and suddenly showed up in every running group chat in the country.

The pitch is loud, and we mean that literally. Bold flavors. Adjustable sodium. Packets that look like something out of an arcade. It's fun, and it works for a lot of people.

But is Mortal Hydration actually right for your day? Or is it built for a very specific kind of effort that may not be yours?

We've been formulating hydration and recovery supplements out of Colorado since 2008, so we know this category well. We also want to be upfront: we make a hydration product too. We're not going to pretend otherwise. We'll give Mortal credit where it earns it, point out the gaps honestly, and let you decide.

Fun coincidence, by the way. Mortal is a Colorado brand too. More on that later.

What Is Mortal Hydration?

Mortal Hydration is a Boulder, Colorado electrolyte drink mix built for athletes, with three different sodium levels so you can match the packet to the effort.

The backstory is a good one. Founder Becca Schepps is a former collegiate rower and professional cyclist. She started Mortal as a kombucha company first, then pivoted into hydration when she saw a gap in how athletes were fueling.

The brand voice leans hard into the name. Their whole line is basically "don't die out there, at least not from thirst or boredom." Cheeky, and honestly kind of refreshing in a category full of beige science talk.

The lineup breaks into three tiers:

• Everyday ... roughly 300mg sodium, zero sugar. Built for sipping at your desk or between sessions.

• Regular ... roughly 450mg sodium with 10g carbs. This is the standard training packet.

• Salty ... roughly 900 to 920mg sodium. For hot days and heavy sweaters.

Flavors run wild by design: Margarita, Aloha, Grapefruit, Berry, Mango, Watermelon. That's the whole point. Mortal argues that athletes over-scoop their hydration mix because most of them taste like sad water, and over-scooping wrecks your sugar-to-water ratio and upsets your gut. Bold flavor at the correct dose solves that.

It's a smart argument. We'd agree with it.

Mortal Hydration Ingredients and Nutrition Facts

Here's where things get useful. Most reviews you'll find online only cover two of the three formulas, because they were written before the Everyday line existed. So here's the full picture.

The Mortal Hydration ingredients list stays reasonably short. The Regular and Salty formulas run on four main electrolytes: sodium, potassium, calcium, and magnesium, plus natural flavors, citric acid, and that cane sugar and dextrose combo. The Everyday version swaps to trisodium citrate, tripotassium citrate, calcium lactate, and magnesium glycinate, with fermented Reb M and monk fruit doing the sweetening.

One thing worth calling out: the whole line is NSF Certified for Sport and produced in GMP-certified facilities. That's not marketing fluff. NSF Certified for Sport means the product gets tested for substances banned by most major athletic organizations, and it verifies the label actually matches what's in the packet. For competitive athletes, that certification is a genuine reason to trust a product.

Credit where it's due. That's a real strength.

Price lands around $29.95 for 25 servings, which works out to roughly $1.20 per packet. Premium, but not outrageous for this category.

The Ironman Deal: What It Actually Means

In 2024, Ironman named Mortal Hydration the official sports beverage and hydration partner for its North American races, including the 70.3 series. Gatorade Endurance got phased off the course.

That's a big deal for the brand. It's also something a lot of athletes misunderstood, and it matters more than it sounds.

Gatorade Endurance and Mortal Hydration are not interchangeable. Sports dietitian Kylee Van Horn, RDN, pointed this out when the news broke: Mortal is an electrolyte mix, not a traditional carb-heavy hydration mix. It carries a small amount of carbohydrate from cane sugar and dextrose, but nowhere near what a fueling drink delivers.

So if you spent a season racing on Gatorade Endurance for your carbs and you grab a Mortal cup expecting the same thing, you're going to bonk. You need to move those carbs into gels, chews, or a separate high-carb bottle.

Mortal is actually designed this way on purpose. Their whole argument is that most endurance athletes are already running a high-carb fueling plan, so the last thing they need is more sugar sneaking in through their electrolyte drink. Fair logic. Just know what you're grabbing.

What Mortal Hydration Gets Right

We spent time with the label and the reviews. Here's what genuinely impresses us.

• The adjustable sodium is a smart idea. Very few brands let you dial sodium up or down inside one lineup. Your sweat rate on a 40-degree morning run is nothing like your sweat rate in August. One brand covering 300mg to 920mg is legitimately useful.

• The flavors deliver. This is the number one thing reviewers rave about. Runners describe Mango and Berry as tart, fun, and easy to drink for hours. When your hydration actually tastes good, you drink more of it. That's not a gimmick, that's behavior change.

• NSF Certified for Sport is real credibility. Third-party banned-substance testing is expensive and most brands skip it. Mortal didn't.

• The Ironman partnership is earned proof. Getting picked to replace Gatorade on a global race series is a serious vote of confidence.

• It solves the over-scooping problem. Bold flavor at the right dose means you're not dumping two scoops in to make it drinkable, which saves your gut and your wallet.

If you're an endurance athlete who wants electrolytes in a bottle without extra carbs piling onto your fueling plan, Mortal is a strong pick. No argument from us.

Where Mortal Hydration Falls Short

Now the honest part. Nothing is perfect, and there are a few gaps worth knowing before you commit.

There's more sugar than a lot of people expect. The Regular and Salty packets carry about 8g of added sugar. On a three-hour ride, that's fine and arguably helpful. Sipping it at your desk on a Tuesday? That's a different conversation. The Everyday line fixes this, but plenty of people buy the Regular packets assuming they're a zero-sugar product. They're not.

The stevia can bite. A recurring theme in reviews is that the flavors run strong, sometimes too strong, and a chunk of users report a stevia aftertaste they don't love. Some say it lingers even after adding extra water. Taste is personal, but it comes up enough to mention.

It's not cheap. At around $1.20 a serving, you're paying a premium. Several reviewers flagged Mortal as one of the more expensive electrolyte options they've tried.

You need water, a bottle, and a free hand. This sounds minor until you're at 35,000 feet, halfway up a fourteener, or three drinks deep at a wedding. A powder is only useful when the water is right there. The second it isn't, the packet just sits in your bag.

It's a workout drink, not a recovery supplement. This is the big one. Mortal replaces fluid and minerals extremely well. What it doesn't do is the deeper recovery work your body wants after alcohol, after altitude, or after a brutal training block. No standardized herbs. No liver support. No recovery-focused amino acids. Electrolytes are one piece of recovery, not the whole thing.

None of this makes Mortal a bad product. It just means Mortal is a sports hydration mix, and that's a narrower job than "hydration and recovery." Depending on your day, that gap matters a lot.

Where to Buy Mortal Hydration

Quick practical note, and one worth reading.

The official brand site is mortalhydration.com (although currently the site appears to be down). You can also find the products through The Feed, which was the original exclusive retailer, and on Amazon.

Here's the thing to watch. When we researched this article, we came across a separate website using a hyphenated version of the brand name. The details on that page do not match anything the actual brand publishes: it lists a different founder name, a different founding year, product names that don't appear anywhere in Mortal's real lineup, and clinical percentages we could not find any source for.

We're not going to speculate about who runs it or why. We just want you to check the URL before you enter a credit card. If the founder story or product names don't match what you see on the official site or at The Feed, close the tab.

That goes for any supplement, ours included. Buy from the brand or an authorized retailer. Always.

Mortal Hydration vs Zaca: The Honest Comparison

Here's where we bring in the alternative, and where we keep it fair.

First, the thing we like about this matchup: Mortal is out of Boulder. We're a Colorado company too. Two brands from the same state, both obsessed with the same problem, both convinced everyone else was doing it wrong. We respect that.

But we built our thing for a completely different moment.

Zaca started in 2008. Two brothers, Mark and James, moved to Denver and got absolutely leveled by the altitude. Headaches. Rough mornings. Workouts that wrecked them for two days. The short version is that we weren't trying to build a better sports drink. We were trying to survive the mountains.

So instead of a powder you mix, Zaca is a berry-flavored chewable hydration tablet you just pop. No water. No bottle. No shaking. It packs standardized herbs like DHM from the Japanese raisin tree, plus prickly pear, glutamine, and glutathione. DHM has been studied at USC for how it supports the liver's ability to process alcohol, which is a completely different job than topping off your sodium.

Think of it this way. Mortal is what goes in your bottle during the effort. Zaca is what goes in your pocket for before and after. One is fuel management, the other is bounce-back.

Let's break it down category by category.

• Race-day electrolyte replacement: Mortal's adjustable sodium, up to 920mg, is built precisely for this. Zaca carries trace electrolytes, not race-day sodium loads.
  Winner: Mortal

• Flavor variety: Six bold flavors versus one mixed berry chewable. Not close.
  Winner: Mortal

• Banned-substance testing: NSF Certified for Sport is a legitimate edge for competing athletes, although Zaca doesn't contain any banned substances, it's just not NSF certified.
  Winner: Mortal

• Convenience: Zaca needs nothing but your mouth. On a plane, a chairlift, or a trail, that's an enormous gap.
  Winner: Zaca

• Sugar: Zaca is zero sugar with no artificial sweeteners, using xylitol and stevia. Mortal's Regular and Salty carry 8g. Their Everyday line ties us here.
  Winner: Zaca

• Recovery depth: This is our home turf. Standardized herbs, liver support, antioxidants, and recovery aminos for alcohol, altitude, and hard training. Mortal doesn't play in this space.
  Winner: Zaca

• Altitude support: Zaca was literally invented to solve altitude misery in the Colorado Rockies. Mortal helps you hydrate, but it wasn't built for elevation.
  Winner: Zaca

Mortal takes race day, flavor, and certification. Zaca takes convenience, sugar, recovery depth, and altitude. Both are good at what they were designed for.

Comparison Chart: Mortal Hydration vs Zaca

Who Should Choose Which?

Forget which brand is "better." Ask which one fits the moment.

Choose Mortal Hydration if:

• You're a runner, cyclist, or triathlete putting in long, sweaty efforts.

• You want to dial sodium up or down depending on heat and conditions.

• You compete and need NSF Certified for Sport testing.

• You want bold flavors you can sip for hours without getting bored.

• You're usually near a water bottle and don't mind mixing.

Choose Zaca if:

• You travel a lot and want something you can take with no water, mid-flight or mid-hike.

• You head to high altitude and want recovery support, not just electrolytes.

• You enjoy drinks and want herbal liver support the next morning.

• You train hard and want amino acids working on recovery.

• You want zero sugar and no artificial sweeteners, every single time.

And honestly? Plenty of people use both. Mortal in the bottle for the long ride. Zaca in the bag for the flight, the summit, and the morning after. They cover different bases, so they stack together just fine.

Mortal Hydration vs LMNT and Liquid IV

Quick context, since these come up constantly.

LMNT is a zero-sugar, very high sodium mix at 1,000mg per stick. It's the most aggressive salt option of the group, popular with keto and fasting crowds. Liquid I.V. runs a moderate-sugar formula with added B vitamins, marketed around faster water absorption. Mortal sits in between, offering adjustable sodium with a small amount of carbohydrate.

All three are powders you mix with water. That's the shared limitation. If you want a no-mix, no-sugar chewable instead, that's where we're different.

We broke these down in more detail in our LMNT vs Liquid IV comparison, our list of alternatives to Liquid IV, and our Skratch Labs hydration review.

Why Zaca Is a Strong Mortal Hydration Alternative

If your reason for reaching for Mortal is "I need to recover and I'm constantly on the move," Zaca is the cleaner fit. Here's the quick why.

1. Chewable, so no water required. Take it on the plane, the trail, or the chairlift. Nothing to mix, nothing to spill, nothing to clump in your bag.

2. Zero sugar, every formula. No 8g of cane sugar hiding in the packet you grabbed. Sweetened with xylitol and stevia instead.

3. Standardized herbs and amino acids. DHM, Hovenia dulcis, prickly pear, glutamine, and glutathione for recovery support, not just fluid replacement.

4. Built and tested at altitude since 2008. We didn't add altitude to our marketing later. It's the exact problem we set out to solve, in the Colorado mountains, before anyone called it a category.

5. One product, many jobs. Travel, altitude, drinks, marathons ,and hard workouts, all in a single chewable.

The Bottom Line on Mortal Hydration

Mortal did something genuinely clever. It made hydration taste good enough that people actually drink it, gave athletes three sodium levels instead of one, and backed it all with NSF Certified for Sport testing and an Ironman partnership. If you're chasing a PR and your bottle needs electrolytes without extra carbs, it's a strong choice.

But it's a workout drink, not a recovery supplement. The Regular and Salty packets carry sugar a lot of buyers don't expect. And it only works when you've got clean water and a free hand.

Zaca takes the opposite approach. No water. No sugar. Just a chewable you can take anywhere, packed with the herbs, hydration support, and amino acids your body wants after travel, altitude, drinks, or a brutal training day. We've been refining it in Colorado since 2008, because that's the exact problem we set out to solve.

Two Colorado brands. Two different jobs. Pick the one that matches your day, or keep both close and cover everything.

Frequently Asked Questions About Mortal Hydration

Is Mortal Hydration good?

For endurance athletes, yes. It delivers a solid electrolyte profile, gives you three sodium levels to match conditions, and it's NSF Certified for Sport, meaning it's third-party tested for banned substances. The main things to watch are the 8g of added sugar in the Regular and Salty packets and the price, which runs around $1.20 per serving. If you want electrolytes without any sugar at all, a sugar-free electrolyte option may be a better daily fit.

What are the Mortal Hydration nutrition facts?

It depends which tier you grab. Everyday runs about 300mg sodium with zero sugar and roughly 5 calories. Regular runs about 450mg sodium with 10g carbs, 8g added sugar, and about 40 calories. Salty runs roughly 900 to 920mg sodium with the same 10g carbs and 40 calories. All three include potassium, calcium, and magnesium alongside the sodium.

How much sodium is in Mortal Hydration?

Anywhere from about 300mg to about 920mg per serving, depending on which line you pick. That adjustable range is Mortal's signature feature. Regular flavors sit around 450mg for typical training, while the Salty versions roughly double it for hot conditions and heavy sweaters.

Does Mortal Hydration have sugar?

The Regular and Salty formulas contain about 8g of added sugar from cane sugar and dextrose, plus stevia. The newer Everyday line is zero sugar and uses fermented Reb M and monk fruit instead. So the answer depends entirely on which packet is in your hand, which trips up a lot of buyers.

Mortal Hydration vs LMNT, what's the difference?

LMNT is a zero-sugar mix with a very high fixed sodium dose of 1,000mg. Mortal offers adjustable sodium from roughly 300mg to 920mg but includes a small amount of sugar in its Regular and Salty lines. LMNT is simpler and saltier. Mortal is more flexible and more flavorful. Both are powders you mix with water. See our LMNT vs Liquid IV breakdown for more.

Where can you buy Mortal Hydration?

Through the official brand site at mortalhydration.com, through The Feed, and on Amazon. Be sure to check the URL carefully, since lookalike domains using similar names do exist online. If the founder story or product names don't match the official site, don't buy from it.

Is Mortal Hydration good for altitude or hangovers?

It helps with the hydration piece, and hydration genuinely matters for both. But altitude and alcohol ask more of your body than fluid replacement alone. Neither one is what Mortal was designed for. If you're heading to the mountains or bouncing back from a night out, look for something with standardized herbs and recovery-focused amino acids. That's the gap Zaca was built to fill, in Colorado, since 2008. Our guide on electrolyte supplements covers more options.
