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.

  • A hydration mix with the power of nutrition science behind it
  • High sodium content gives your depleted body what it needs
  • No artificial junk or filler makes it easier on the belly
  • Subtle, all-natural flavors go down gently during hard efforts
  • Formulate for exercise specifically—try another hydration mix for daily hydration

No More Cramps

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

Great product. You should definitely get this as a preventive measure. No cramps = better rides!

Matcha Heaven

  • Familiarity: I've put it through the wringer

Stomach issues are a thing of the past for me, thanks to this mix. If you're in the market to try a hydration mix, definitely give this a shot. While the matcha flavor might not be for everyone, it's my go-to for feeling refreshed and fueled on long runs. Cannot recommend this more!

Fabulous Stuff

    Since I read about the guys behind Skratch Labs, i have tried and used their powdered drinks. They are competitively priced (too expensive but that is kind of the going rate). I have stuck with citrus flavors mostly and I've never had digestion or stomach ache issues. My preferred mix is to blend in a 50-50 ratio of the lemon/lime with the matcha/lemon. Sometimes on long rides the sweetness of citrus gets "sticky" even without sugar. So, the matcha gives it a bitterness that means I can drink it on any ride - short or long.


    • Familiarity: I've used it several times

    This is my favorite hydration mix. The lemon lime in particular. I use this on a daily basis now and recommend it to anyone looking for a good hydration formula.

    Go-To Hydration

    • Familiarity: I've put it through the wringer

    Scratch labs is the only hydration mix that I use, preferably orange on regular days and lemon-lime on hot days.

    Keeps you hydrated

    • Familiarity: I've put it through the wringer

    This is the best Hydration mix. The Lemon lime flavor tastes great and works exactly how I want.

    The right fuel the right tool

    • Familiarity: I've put it through the wringer

    If you're an endurance athlete, look no further. Skratch gives you what your body needs. It won't upset your stomach because there's no junk in it. Very easy on the palette so you drink it like you actually like the taste.. It's a hydration mix that changed the industry. I highly recommend it.

    Skratch Labs Exercise Hydration Mix

    • Familiarity: I've put it through the wringer

    I'm very active and I haven't ever used a product like this. It really helps me power through long intense periods of exercise and work. Nice lemon flavor that doesn't over power you with sweetness. My go to refueling drink source. Looking forward to trying more flavors.


      Love skratch for maintaining electrolytes and hydrating quickly. I’m a big fan of the pineapple flavor and don’t find it overly sweet or sugary, just good flavor.

      IMO - one of the best hydration products

      • Familiarity: I've put it through the wringer

      Title is pretty self explanatory...I've tried a lot of hydration products and even dabbled with making my own, but I keep coming back to this. I was using for a long time and it's never let me down

      Hydration that doesn't suck

      • Familiarity: I've put it through the wringer

      I am a scratch labs believer! They have really done their homework and it has resulted in a great drink mix that will keep you from cramping, but will also provide you with flavor that is not a terrible mockery of (in my case) Lemon Lime. Seriously though, I have had a few other drink mixes over the years and they usually lack in the flavor department, and while they focus on replenishing electrolytes, they don't really do much for energy and taste terrible. Skratch Labs to save the day, it tastes great without being too sweet like a typical

      Gotta have it

      • Familiarity: I've put it through the wringer

      I seriously love this stuff. I have been using another drink mix for years until I tried Skratch Labs. The flavor is so much better! I really like the lemon-lime and pineapple flavors. It dissolves really well and is perfect for any occasion when you sweat.

      Mhm, mhm!

        The apple cinnamon flavor is rapidly becoming my favorite, over my long-held loyalty to the pineapple. For those winter rides, the hot apples and cinnamon makes it way easier to stay hydrated even when the temperature drops.

        Yes to the apple cinnamon flavor! Off the hook.

        Skratch hydrating during Speedgoat 50k

        • Familiarity: I've put it through the wringer

        I'm going on two years of using Skratch Labs for all my endurance training and racing, and it's amazing. For my longest mountain days, I'll preload with a glass, and then take a bottle of the exercise mix and then some hypermix powder to refill along the way. All the flavors taste great though my favorite is the raspberry. If you haven't tried the Apple Cinnamon yet, give it a try after your cold workouts. Amazing stuff!

        The Best Stuff Outthere

        • Familiarity: I've put it through the wringer

        I can't count how many bags of this stuff I've used over the last couple years.

        The only flavors I haven't tried is the Strawberries and the Passion Fruit. I'd definitely like to give those a shot.

        I'm a big fan of the individual servings when on extended trips. I used this stuff on Mt Rainier and definitely was a nice way to add some happiness to some junk weather by drinking some warm Skratch.

        Favorite Flavors:

        1 - Lemon Lime - this is by far the best flavor and mixes the best
        2 - Orange - this also mixes real well and tastes great
        3 - Apples & Cinnamon - this is best warm and with a little whiskey
        4 - Matcha Lemons - tastes good, I'm just not big on caffeine
        5 - Pineapple - I'm not a pineapple flavor lover, but this is definitely the best tasting pineapple food I've had.
        6 - Raspberry - This one mixes the worst of all the flavors I've tried but tastes good

        Flavors TBD: Strawberries / Passion Fruit

        Great Supplement for High Intensity

        • Familiarity: I've used it several times

        This product has been super helpful when going on longer bike rides with plenty of climbing. Normally I am just drinking this on the climb and save some water for the downhill. I have also used it for some longer distance day hikes or after a long party night. Great way to stay hydrated!

        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.
