Not just a sports drink. A precision fueling system.

Most athletes running longer than an hour are leaving performance on the table, not because they're undertrained, but because they're under-fueled. Glycogen depletion doesn't announce itself. It creeps in as slowed pace, fading focus, and legs that stop listening. By the time you feel it, you're already behind.

Salty Carbs was built to solve this at the source. Every serving delivers 30g of carbohydrates and a full electrolyte profile mixed into your water bottle, sipped during the effort, and absorbed efficiently enough to keep you moving at the pace you trained for.*

BENEFITS

Why two carb sources are better than one.

Most carbohydrate supplements use a single source, typically maltodextrin or glucose. The problem: your gut has a ceiling on how fast it can absorb carbohydrates through any one pathway. Push past that ceiling and you get undigested carbs sitting in your gut, fermentation, bloating, and the kind of GI distress that ends races.

Salty Carbs uses a clinically-studied 1:0.8 ratio of maltodextrin to fructose, two carbohydrates that absorb through completely independent pathways in the small intestine.

Maltodextrin is absorbed via the SGLT1 transporter
Fructose is absorbed via the GLUT5 transporter

By using both pathways simultaneously, Salty Carbs effectively doubles your carbohydrate absorption rate without overloading either transporter. More carbs absorbed means more fuel delivered to working muscles. Less undigested carbs in the gut means less distress mid-effort.*

The result: sustained energy output at higher intensity, for longer without the spike, the crash, or the rest stop detour.*

INGREDIENT DEEP DIVE

Non-GMO Maltodextrin A glucose polymer derived from Non-GMO corn. Fast-absorbing, easy on the gut, and efficiently converted to glycogen for immediate muscular energy. Absorbed via the SGLT1 transporter, the primary pathway for glucose uptake during exercise.*

Non-GMO Fructose Also derived from Non-GMO corn. Fructose uses a completely separate absorption pathway (GLUT5) to maltodextrin, allowing simultaneous uptake without competition or overload. At the 1:0.8 maltodextrin-to-fructose ratio used in Salty Carbs, research shows meaningful improvements in carbohydrate oxidation rates versus maltodextrin alone.*

700mg Sodium Chloride Sodium is the primary electrolyte lost through sweat and the most critical to replace. At 700mg per serving, Salty Carbs delivers a meaningful dose instead of the token amounts found in most sports drinks. Sodium also drives thirst and encourages continued fluid intake, which matters on long efforts.*

Potassium Citrate Potassium works alongside sodium to maintain fluid balance across cell membranes. It supports neuromuscular function and helps prevent muscle cramping during prolonged exertion.*

Magnesium Malate Magnesium is involved in over 300 enzymatic reactions, including energy production and muscle contraction. Magnesium malate is a highly bioavailable form that's gentler on the stomach than cheaper forms like magnesium oxide.*

BUILT FOR YOU

Built for athletes who go long.

Runners training beyond 60 minutes who've experienced the wall, the fade, or race-day GI issues from gels.
Cyclists who need reliable, stomach-friendly fuel across hours in the saddle.
Triathletes managing nutrition across three disciplines with no room for GI error.
Team sport athletes who need to maintain output through repeated high-intensity efforts.
Anyone who's tried cheaper carb supplements and paid for it in stomach cramps mid-session.

If your performance drops off in the second half of your training or races, this is the fix.*

HOW TO USE

Mix one serving with 12–14 fl oz of water. Shake well.

Pre-workout: Take 30 minutes before a long or intense session to top up glycogen stores.
Intra-workout: Sip continuously from the start of sessions lasting 60 minutes or longer. Aim for roughly one serving per hour of effort.
Post-workout: Can support glycogen replenishment after intense sessions and is particularly useful when a full meal isn't immediately available*.

Dosing note: General sports nutrition guidelines recommend 30–60g of carbohydrates per hour of endurance exercise. One serving of Salty Carbs provides 30g, so adjust based on session length, intensity, and individual tolerance.

FAQs

How much Salty Carbs should I take per hour?

General guidelines recommend 30–60g of carbohydrates per hour of endurance exercise. Each serving provides 30g. For sessions over 90 minutes or at high intensity, aim for one serving per hour as a starting point and adjust based on your personal tolerance.*

Why does Salty Carbs use two carbohydrate sources?

Maltodextrin and fructose absorb through two completely independent pathways — SGLT1 and GLUT5 respectively. Using both simultaneously allows a higher total rate of carbohydrate absorption without overloading either transporter. More fuel to muscles, less undigested carbs causing GI distress.*

Is fructose hard to digest?

In large doses on its own, yes. Salty Carbs uses a 1:0.8 maltodextrin-to-fructose ratio, the same ratio used in peer-reviewed research on dual-carb endurance fueling, keeping fructose at a well-tolerated level while still benefiting from the second absorption pathway.*

When should I start drinking Salty Carbs during a workout?

Don't wait until you're depleted. Start sipping 15 minutes into your session and continue at regular intervals. Your body can only absorb carbohydrates at a fixed rate so feeding consistently from the start prevents the deficit that causes late-race fade.*

Can I stack Salty Carbs with other RNWY products?

Yes! Salty Carbs fits cleanly into the full RNWY stack. Take Extra Mile® pre-workout, Salty Carbs during the effort, and Complete Protein post-workout for a complete fueling window from start to recovery.

Is Salty Carbs vegan?

Yes. All five ingredients are plant-derived. No animal products, dairy, or animal byproducts of any kind.

Game Changer for Training

"I can't say enough about Salty Carbs. It makes it so simple to get both carbs and electrolytes throughout your training run, and it is easy on the stomach! Plus, it takes good, but doesn't have an overly strong taste. I love every flavor, but my favorite is the Raspberry Lemonade!"

— Maddie (5/5)

Salty Carbs the BEST CARBS

"I recently tried SaltyCarbs by RNWY and I’m honestly impressed. As someone who’s pretty active, I’m always looking for something that actually helps with hydration and energy without feeling heavy or overly sweet—and this delivered. I actually trained for multiple marathons using this, and it made a noticeable difference in my endurance and recovery. The balance of electrolytes and carbs feels just right. During long runs, my energy stayed steady, and I didn’t hit that same level of fatigue or dehydration I’ve experienced in the past. It mixes easily, tastes clean (not that artificial aftertaste you get with some products), and doesn’t upset my stomach. What I appreciate most is how simple and effective it is—no unnecessary extras, just something that works. Definitely keeping this as part of my training routine, especially for long runs and hot days. If you’re looking for a hydration + fuel combo that actually performs, SaltyCarbs is worth trying."

Salty Carbs is a must for my training

"Salty Carbs not only tastes good, it’s easy on the stomach and packs not only electrolytes but carbs too. It has been a game changer in my marathon training!"

— Ash (5/5)

Game-changer for long runs

"This has honestly been a game changer for my training and long runs. The carbs + electrolytes combo is exactly what I need to keep my energy up, especially on harder or longer efforts. It’s easy to drink, doesn’t mess with my stomach, and the flavor is actually really good. I’ve been reaching for it every long run lately and it’s been working really well."

— Laura I. (5/5)

A Game-Changer for Hydration & Fueling Rating: ⭐⭐⭐

"I’m really impressed with RNWY Salty Carbs. The taste is excellent across the board, but the Unflavored option is surprisingly delicious—it’s clean and easy to drink without that artificial aftertaste you find in other brands. The biggest win for me is the convenience. Being able to get my carbs and sodium in simultaneously with my hydration is a total game-changer. It’s so much better to take these in as a liquid rather than dealing with the sticky mess and digestive heaviness of gels. If you're looking for a streamlined way to fuel and hydrate at the same time, this is it."

— Chad M. (5/5)

Quickly Becoming My Favorite Fuel

"I've been using this product for a few months now and it has become a staple in my training and racing lineup! I used it in Berlin during a particularly hot marathon and I was so happy that I had Salty Carbs in my bottle when things got tough and I couldn't take gels any longer. It kept me fueled and hydrated until the very end and I was able to pull off a 6 minute PR!"

— Kristin L. (5/5)

Salty carbs are a game changer

"Salty carbs are great for my long runs! Most gels struggle on the electrolyte side, so getting over 1g of electrolytes into 12oz of water is night and day for training. Raspberry lemonade is my go-to. This also sits better in my stomach than gels, so if you struggle with that, give salty carbs a try!"

— Izaiah R. (5/5)

My Favorite Long Run Fuel

"Hydration and carbs in one has been a game changer for marathon training."

— Ashley T. (5/5)

Salt Carbs is a game changer!

"My favorite carbs to use before long runs as it has the perfect about of carbs and sodium. Plus the taste is VERY GOOD! By far the best product!"

"This product really fuels my engine. I don’t know what I would do without it on my long runs. The taste is great."
