Silence. That's all Dr. Allen Lim heard when he knew he had arrived at a solution. No longer were his Garmin riders complaining of the headaches and bloated stomachs that had plagued them for so long. Lim had spent countless hours mixing formulas in buckets to create not a product, but a solution that was informally dubbed Secret Drink Mix, or SDM. Why a secret? Because word had spread through the peloton that Lim had perfected a hydration solution that was effective and delicious, and it led to many pros pouring out the electrolyte-heavy, overly sweetened beverages provided by their sponsors and replacing it with Lim's contraband. Fortunately for us, the secret is out, and Lim is offering this pro-developed and battle-tested solution to the world. It's now called the Exercise Hydration Mix, from Lim's Boulder, Colorado-based Skratch Labs.

Unlike many sports drinks, which are formulated around electrolyte or caloric replenishment during physical exertion, the Exercise Mix focuses on keeping your body's sodium levels carefully regulated. Lim discovered that the rampant headaches plaguing his pro riders were not induced by a lack of fluids, but rather, a lack of sodium -- a very typical symptom of dehydration. Essentially, your kidneys regulate fluid retention based on the body's concentration of sodium. When sodium concentration is high, your body is forced to hold on to that fluid to dilute it. But when your sodium levels get too low (ie: through sweat loss), the opposite happens and your kidneys must expel that fluid. 

Lim's mix is designed to keep your body's sodium balance carefully regulated, maintaining hydration while also slowing diuresis. With diuresis slowed, you'll be able to pre-hydrate and drink more before a race without needing to make those three inopportune bathroom breaks right before your call-up. If these concepts around a sodium-based formula sound familiar, that's because they are -- Lim's drink mix contains nearly four times the amount of sodium in many convenience-store sports drinks, putting it on par with emergency-grade rehydration salt formulas like Pedialyte, and those used by the World Health Organization to combat severe dehydration.

The athletes that helped Lim develop the Exercise Mix weren't just complaining of headaches. They were also suffering from severe stomach bloating and flavor fatigue. The second half of Lim's solution was to ensure his drink was easy and pleasurable to consume day in and day out. To accomplish this, every ingredient from the Exercise Mix is naturally occurring or naturally sourced from real fruit, which ensures you're not putting anything in your body that's been chemically formulated or enhanced. In short, if it wasn't here on this earth before you were, Dr. Lim and his team refused to use it. 

The ingredients are: sucrose, glucose, sodium citrate, potassium citrate, calcium citrate, magnesium citrate, freeze dried fruit, citric acid (a natural preservation agent from pure lime juice), and ascorbic acid. Notice the pronounced absence of the 'natural flavors' found in so many other sports drinks. Part of what makes the Exercise Mix so uniquely palatable even during prolonged periods of exercise and constant re-hydration is the lack of a savoring agent. Generally, chemically-derived flavoring agents like those ominous 'natural flavors' tend to remain on your palate, causing flavor fatigue, and in larger doses, wreak havoc on your gut. 

The Exercise Mix uses real lemons, limes, oranges, and raspberries, which are freeze-dried and pounded into powder. This creates a refreshing, super-clean flavor that's easy on your stomach without a lingering aftertaste that wears out its welcome halfway into your race. It means you're not just getting a 'flavor' of lemon or orange, you're getting actual lemons and oranges in the mix. This is one of the many fundamental breakthroughs behind the Skratch Labs drink mixes. Whether you're staying hydrated during a 24-hour endurance race, or re-hydrating after a grueling criterium, they simply taste great.

Lim and his team created two drink mixes, optimizing each for different levels of physical exertion. This Exercise Hydration Mix has a slightly higher salt content, making it Skratch Labs' on-bike mix, best used for periods when your heart rate is up and you're sweating. Because this mix has a supremely high absorption rate and is not a natural diuretic, it's excellent as a preventative measure against dehydration while you ride, when you stop at an aid station, or immediately after your workout or race, because you can drink a larger volume of it at a time without painful bloating. This is due in part to the drink's exceptionally low levels of acidity, and lack of chemically-enhanced flavors.

The Skratch Labs Exercise Hydration Mix is available in Lemon Lime, Orange, or Raspberry. Each one-pound package should provide approximately twenty (23 grams dry), 500ml servings.

No race gut

  • Familiarity: I've put it through the wringer

Skratch has become my go to for drink mix. When it comes to days in the saddle, training or racing, this stuff is perfect! It's easy on your stomach and doesn't have an overly sweet taste, but still gives the nutrients needed when pushing your body to the limits. My favorites are the lemon and matcha tea(w/caffeine). I race cat1 road and have been ordering this from backcountry for almost two years now and couldn't be happier, great prices and customer service!

Thanks for the review Sterling! Super helpful to get this feedback out to the community.

No more headaches

  • Familiarity: I've put it through the wringer

Well Alan Lim is a genius. My post ride headaches are gone. Additionally my soccer playing daughter has a great mid/ post training and game refuel without carb overload! Lemon lime tastes GREAT!

skratch for the win

  • Familiarity: I've put it through the wringer

Skratch labs is my go-to hydration mix. Works better and is better tasting than others... and I've tried lots. The only downside, is I like to use tablets for on-road refills. The single use packets that Skratch uses just aren't as convenient.

My first experience with Skratch :)

    Not a load of snake-oil. I drink much more water now than I did before, and I have felt so much better because of it! Taste on this is great, the added salts/sugars keep you hydrated and coming back for more. Orange definitely mixes easier and even tastes fine when warmed up due to air temps.
    Try a bag, I bet you don't go back.


    • Familiarity: I've put it through the wringer

    I like this because it has a subtle flavor so it is not overpowering, it is easy to drink, and has no bad aftertaste. When used comparatively with just regular water, it definitely helps to diminish cramping. Also it tastes good if it get warm, and on long road rides that can be important. It comes with a scoop which is nice as well. I used to use a different brand in both of my bottles, now I just use this and supplement with regular water.

    No bad stuff in this drink

      I've been using this stuff for years. It's always refreshing knowing what ingredients you are using in your sports drinks. So many out there have so much "stuff" in it, it's hard to know if it is really helping you. This stuff has clean, healthy ingredients. It also tastes so good, I even like to put a smaller dose in my water for a little bit more flavor for daily drinking.

      New Go To Hydration

      • Familiarity: I've put it through the wringer

      After having used most of the top hydration mixes, finally decided to give Skratch a go. They seemed to have figured out the right balance between sodium and electrolytes without giving it a super overly sweet taste. Goes down easy with no rot gut issues and keeps me pedaling.

      Love it!

      • Familiarity: I've used it several times

      A scoop in a bottle...tastes great! A scoop in my post-ride strawberry banana smoothie...tastes great! Not much to Skratch other than easy to digest carbs and electrolytes. Easy on the stomach and refreshingling good tasting.

      Lemon Lime and Pineapple - Hydrate

        Love this stuff. My two favorite flavors are lemon lime and pineapple. This is easy on the stomach and is great for all types/distances of riding. Light taste and not too sweet. Easy to clean out of bottles when you are done.

        A fantastic hydration solution

          After years of drinking syrupy, sugary water while still getting cramps, change had to come. I gave skratch a try and I was hooked. Very simple ingredients and light taste to complement hard training session day in and day out. I dont get tired of it, even after 4 bottles on long days.

          Still Using It

          • Familiarity: I've put it through the wringer

          Admist a market flooded with options I'm still coming back to this stuff for its simplicity, delicious flavor, and availability. I seem to have zero digestive issues with it and it goes down fairly easy, even after lots of hard efforts in extreme heat.

          Great Hot Weather Recovery

          • Familiarity: I've put it through the wringer

          I commute 30 miles a day regardless of the weather in the Washington DC area. These hot summer days can easily take it out of you when it’s humid and well into the 80’s in the morning and a humid 90+ in the afternoon. I’ve been mixing a bottle of this in the morning and drinking it after I get to the office to speed recovery for the afternoon ride. I find the lemons & limes flavor to be good – not too strong and it doesn’t bother my stomach when I’m on a longer ride. I also hate using anything other than water when I’m actually riding but I don’t have the same aversion to this product.

          Perfect drink for high output activities

          • Familiarity: I've used it once or twice and have initial impressions

          This is the perfect mix for high output activities such as biking or running. Ill fill up one of my bottles with this before I head out and it keeps me feeling better and going longer than any other mix I've tried.

          Great Product - Great Taste

            I recently tried this product on a very long multi-day ride with friends and loved it. I have since purchased Lemon-Lime and Raspberry and recommend them highly. I had previously been using Endurox much too expensive.

              Scratch Exercise Hydration mix is a staple for all of my rides, runs, and ski tours. Both the lemon lime and raspberry flavors taste great, and go down easy even especially when it's hot and you're working hard.

              It's a great way to keep the sugar reserves topped off while also replacing electrolytes.


              • Familiarity: I've put it through the wringer

              The Orange and Lemon-Lime flavors are my favorites. I usually use it during or after long MTB rides, especially when it's hot. I like the bag / scoop format vs the individual pouches so I can vary how much goes into my water bottles. Overall, this is my favorite hydration mix.

              Light, delicious and hydrates!

              • Familiarity: I've put it through the wringer

              UPDATE: I have now tried all seven flavors - add Passion Fruit and Strawberries to the list. Passion Fruit is my favorite, though I will drink any of them very happily. Matcha + lemons is the fifth flavor of Skratch Labs Hydration Mix I have tried. The others are Raspberry, Pineapple, Apples & Cinnamon, and Orange. I like them all and am perfectly happy switching between them as my mood suits.
              I prefer all of them cold (except Apples & Cinnamon in the winter), so I use an insulated bottle and freeze it. By the time I'm ready for my first drink, it has melted sufficiently. No stomach upset, a little boost from the sugars, and a nice taste. And no cramps.
              In the winter, I use a much more insulated bottle and drink the Apples & Cinnamon hot. What a treat.
              Love this product and highly recommend it. BTW - the only complaint, and this is small, is that there are tiny pieces of raspberry seeds in the raspberry flavor. Sometimes they gunk up my water bottle spout. A tiny complaint, to be sure.

              Hey Casey! Thanks for the kind words and glad to hear Skratch has been working for you out there. The freezing tip is a good one for sure and something we do a lot in the summertime to stay cool.
              I hear you on the seediness of the Raspberries. Kinda like how I don't prefer pulp in my OJ. Because we use real fruit it tends to have a lot of seeds that can cause some grittiness to the drink. We've had die hard Raspberry Skratch fans run the mix through a strainer before to get a non seedy batch. Not a perfect solution but something to try if you are jonesin' for some Raspberry Skratch sans seeds.
              Please don't hesitate to reach out if we can help with anything else!


              Hey, thanks Mark from Skratch Labs for your reply. Good suggestion on the seeds - it is a teeny tiny, minor issue and the minuscule problem is offset by the benefit of *real* ingredients and efficacy of the product!
              I would love it if flavors other than Lemons & Limes were available in 3 lb pouches. :-)

              much easier on my stomach than others

              • Familiarity: I've put it through the wringer

              it doesn't taste so sugary like some others but definately helps me hold off cramps in the heat

              It's got electrolytes

              • Familiarity: I've put it through the wringer

              Most of the time, science lauding 'sports nutrition' feels more like wishful thinking than genuine research.
              Skratch's hydration mix is the rare exception.
              It tastes fine, and helps me avoid getting dehydrated over the course of a weekend camping.
              I appreciate Skratch's focus on digestion, and I havent had any stomach issues that I associate with the drink.
              Ultimately... 'it's got electrolytes.'

              Easy to use and easy on the belly

              • Familiarity: I've used it several times

              I bought the matcha/lemon flavor. I'm always nervous to try new fuel but this one works well. It's not sweet... which is why I like it. It's a little tangy and sour, probably from the lemon flavor. I like how it is naturally caffeinated with green tea. I don't drink coffee, but drink a lot of tea and tolerated the caffeine amount just fine. Plus, it doesn't stain my water bottles.
