Athlete mixing hydration drink in Singapore

400 mg Sodium: Skratch Labs Hydration, Singapore, Buy via Racepack SG

For most training sessions and races, Skratch Labs Sport Hydration Drink Mix is the smart default: it delivers roughly 400 mg of sodium and 19 to 20 grams of carbs per serving in a real-fruit base that’s gentler on the gut than most sugary sports drinks. Pair it with the Unsweetened version for low-carb days or the Electrolyte Booster when the heat cranks up your sodium needs. You can pick up any of these through Racepack SG, where a single-serving trial or a variety pack is the easiest way to find your fit.

TL;DR:

  • Most athletes doing sessions longer than 90 minutes should start with one serving of Skratch Sport Hydration per hour and increase if sweating heavily or in heat.
  • One serving provides about 400 mg of sodium and 19 to 20 grams of carbs, aligning with standard endurance nutrition targets, but over-consuming beyond two servings per hour is unnecessary for most.
  • The Unsweetened version suits low-intensity or short sessions under 90 minutes, while the Super High-Carb Mix is ideal for ultra-distance efforts exceeding 60 grams of carbs per hour.
  • Proper hydration requires timing and personal sweat-rate testing to avoid over-drinking plain water, especially in hot conditions, with watchful eye on weight changes during activity.
  • Buying from trusted sources like Racepack SG ensures product authenticity, appropriate pack sizes, and timely delivery, critical for race preparation and avoiding counterfeit products.

What Is Skratch Labs Hydration and Which Product Fits Your Session?

Skratch Labs built its hydration line around one idea: sports drinks shouldn’t taste like candy or wreck your stomach mid-race. The company uses real fruit for flavoring instead of artificial sweeteners, and its labeling emphasizes a lower osmolality formula designed to sit easier in your gut during hard efforts, a claim the brand backs up across its hydration product line. That’s the core pitch behind skratch labs hydration mixes, and it’s why so many endurance athletes reach for them over conventional neon-colored drinks.

The lineup breaks into four practical categories, and each one solves a different problem:

  • Sport Hydration Drink Mix is the general-purpose workhorse. It’s built for sessions running one to three hours, whether that’s a tempo run, a century ride, or a half-marathon effort. Most athletes start here.
  • Unsweetened Sport Hydration Mix strips out the carbohydrates and keeps the electrolytes. It works well for short, low-intensity sessions where you don’t need fuel, or when you’re already eating solid food and just need sodium replacement without adding sugar on top.
  • Electrolyte Booster is a concentrated sodium add-in, not a standalone drink. Mix it into your regular bottle when conditions turn hot or when you know you’re a heavy, salty sweater who needs more than a standard serving provides.
  • Super High-Carb Mix targets ultra-distance and very high-output efforts, where your body can burn through carbohydrate faster than a standard sports drink can replace it.

Pack sizes vary by product, with resealable bags in different serving counts and single-serving packets for travel or race-day testing. If you’re not sure which flavor or format suits your palate, a variety pack approach lets you sample several before committing to a bulk bag. For Singapore-based athletes juggling heat and humidity most of the year, the Electrolyte Booster tends to earn a permanent spot in the gym bag faster than in cooler climates, simply because sweat losses run higher here.

One more distinction worth knowing: Skratch’s Sport Hydration mix is not an energy gel replacement. It’s built to travel in your bottle, not your pocket, so pair it with GU or SiS products when you need concentrated carbs on the move rather than in solution.

How Much Sodium and Carbohydrate Does Each Serving Provide?

A standard serving of Skratch Sport Hydration Drink Mix delivers about 400 mg of sodium and 19 to 20 grams of simple carbohydrates, mixed into 350 to 500 mL of water. Those two numbers matter more than almost anything else on the label, because they determine how well your body actually holds onto the fluid you’re drinking.

Why sodium comes first: Sodium drives the glucose co-transport mechanism in your gut, which is the process that pulls both sodium and glucose across the intestinal wall together. Drink plain water without electrolytes during a long, sweaty effort, and you can dilute your blood sodium levels faster than you replace fluid, a mismatch that’s often behind cramping and, in extreme cases, hyponatremia.

Sports nutrition guidance generally points to two per-hour targets for long or hot sessions: 300 to 700 mg of sodium and 30 to 60 grams of carbohydrate per hour, with the higher end reserved for heat, humidity, and heavier sweaters. Skratch’s serving size maps onto those targets cleanly once you do the arithmetic.

Here’s how that plays out in practice:

  • One serving per hour gives you roughly 400 mg sodium and 19 to 20 g carbs, which sits comfortably within both target ranges for a moderate-intensity, moderate-heat session.
  • One and a half servings per hour (common on hot days or for salty sweaters) pushes you toward 600 mg sodium and 30 g carbs, near the top of the sodium range.
  • Two servings per hour stacks up close to 800 mg sodium and 40 g carbs, appropriate only for very heavy sweat losses or genuine heat stress, not a default setting.

Shorter sessions under 90 minutes in mild conditions often don’t need this level of electrolyte replacement at all, and plain water or a diluted mix covers most casual training days. The moment you push past 90 minutes, add heat, or notice heavier sweat staining on your kit, that’s your cue to move from casual hydration to a planned sodium and carb strategy. Understanding your own electrolyte balance here is the difference between a drink that works with your body and one that just sits in your stomach.

How Do You Mix and Time Skratch Hydration During a Session?

Skratch’s own mixing directions call for one scoop per 12 to 16 fl oz of water, which is roughly 350 to 500 mL. That’s a wider range than most sports drinks allow, and it’s intentional: it lets you dial concentration up or down slightly based on taste tolerance and how much fluid you actually want to carry.

Start simple and adjust from there. Here’s the sequence that works for most athletes:

  1. Begin with one serving per hour on any session over 60 to 90 minutes. This is your baseline, not your ceiling.
  2. Increase toward 1.5 servings per hour once temperature, humidity, or effort intensity climbs, or if you already know from experience that you sweat heavily.
  3. Add an Electrolyte Booster scoop rather than doubling the Sport mix if you need more sodium but don’t want the extra sugar load.
  4. Reassess every 30 to 45 minutes during long events, since sweat rate can change as fatigue sets in or conditions shift.
  5. Log your intake so you build a personal reference point for future races in similar conditions.

Running a sweat-rate test before a big event takes the guesswork out of steps two and three. Weigh yourself nude immediately before a representative one-hour session, don’t drink anything during it, then weigh yourself nude again immediately after. The weight difference, converted to milliliters, is roughly your hourly sweat loss, and field-tested rehydration guidance suggests keeping body-mass losses under about 2% during exercise and replacing 100 to 150% of that fluid loss afterward if your recovery window is tight.

Pro Tip: Run your sweat-rate test on a day that matches your race conditions as closely as possible. Testing in an air-conditioned gym and then racing in outdoor heat will underestimate your real fluid needs by a wide margin.

On safety: the general rule is drink to thirst for easy, short efforts, but plan ahead for long or hot events rather than relying on thirst alone, since thirst signals often lag behind actual fluid need once you’re deep into a race. The bigger danger for most recreational athletes isn’t under-drinking, it’s over-drinking plain water without enough sodium alongside it. Watching for unexpected weight gain during a race is one of the clearest signs you’ve crossed that line.

Unsweetened, Booster, or Super High-Carb: Which One Do You Actually Need?

The three specialty products in the Skratch line solve narrower problems than the standard Sport mix, and picking the wrong one usually means you’re either under-fueling or overcomplicating a simple bottle.

  • Choose Unsweetened when you’re doing a low-intensity session, an easy recovery ride, or any workout under an hour where carbohydrate replacement isn’t the priority. It’s also a smart pick if you’re already eating solid food during a long event and just need the sodium topped up without stacking more sugar on top.
  • Dose the Electrolyte Booster in half-scoop increments rather than guessing at a full scoop. This lets you nudge sodium content up gradually, which matters because oversalting a drink makes it unpalatable fast, and a drink you can’t stomach doesn’t help anyone.
  • Reach for Super High-Carb Mix once your hourly carbohydrate needs exceed 60 grams, which typically means ultra-distance events or very high-output efforts where the standard Sport mix alone can’t keep pace with what you’re burning. Many athletes combine it with GU or SiS energy gels rather than relying on drink mix alone for extreme carb loads.
  • Rotate flavors across a race season to avoid palate fatigue. Drinking the same flavor for six hours straight during an Ironman is a common reason athletes stop drinking enough late in a race, and a variety pack solves that before it becomes a problem.

If you’re stacking carbohydrate sources for a very long event, keep total carb intake across gels, chews, and drink mix in the 30 to 90 gram per hour range depending on your training and gut tolerance, and build that combination during training long runs, never for the first time on race day.

Where to Buy Skratch Hydration and What to Check Before You Order

Buying from an authorized retailer matters more with sports nutrition than most categories, because expired stock or counterfeit packaging can mean you’re getting the wrong sodium and carb numbers exactly when you need them to be right. A few things worth checking before you order:

  • Read the nutrition panel on the product page, not just the marketing copy, to confirm sodium and carb numbers match what you expect for that specific flavor and SKU.
  • Look for resealable bag packaging on multi-serving sizes, since a bag that won’t reseal properly lets moisture in and clumps the mix over time.
  • Compare pack-size value per serving, not just the sticker price, since a 20-serving bag often costs less per scoop than repeatedly buying smaller packs.
  • Factor in shipping costs and delivery speed, especially if you’re ordering close to race day and can’t afford a delay.
  • Start with a variety pack or single-serving trial if you haven’t used a particular flavor before, rather than committing to a large bag on a flavor you’ve never tasted.

Racepack SG carries Skratch Labs Unsweetened Hydration Sport Drink Mix in 10 and 20 pack sizes, backed by a guarantee of product authenticity and next-day delivery for orders placed within Singapore. That combination matters for athletes training on a schedule, since discovering your hydration mix is out of stock three days before a race is its own kind of stress you don’t need. You can browse the full Skratch Labs range alongside complementary products before deciding what belongs in your race kit.

Why Racepack SG Is a Reliable Source for Skratch Hydration

Some retailers stock focused catalogs including energy gels, hydration mixes, protein powders, recovery formulas, and sports watches from established international brands, curated for endurance athletes rather than casual shoppers. Guaranteeing product authenticity is important in this category due to the risk of counterfeit or gray-market stock among lower-priced offerings online.

Some retailers emphasize guaranteed authenticity on every product, next-day delivery within Singapore, and a shopping experience built specifically around what athletes need before a race rather than general retail convenience.

That focus shows up in practical ways, like grouping hydration products by use case rather than by brand alone, and publishing blog guidance such as the breakdown of electrolyte needs during high-intensity training so athletes can match a product to their actual training load instead of guessing.

This article is written by Jason John, drawing on sports nutrition research and product-label analysis rather than personal testing claims, to give athletes a purchase-ready breakdown of what Skratch products actually deliver and where to source them reliably.

How Long Does Skratch Hydration’s Benefit Last During a Race?

Hydration and electrolyte support don’t work like a switch you flip once and forget. The benefit of any serving of Skratch Sport Hydration lasts roughly as long as it takes your body to process that fluid and sodium, generally about 45 to 90 minutes depending on your gut absorption rate, sweat rate, and how much you’re moving.

That’s exactly why the one-serving-per-hour baseline exists: it’s not a single dose meant to carry you through an entire race, it’s a maintenance rhythm designed to keep pace with ongoing sweat losses. Stop drinking for two hours in the middle of a marathon, and whatever sodium and carbohydrate benefit you built up earlier starts fading as your body continues losing both through sweat.

Hydration serving rhythm across race hours

This is where a lot of athletes get the timing wrong. They load up heavily in the first 30 minutes of a race, feel great, then under-drink for the middle stretch once the initial buzz wears off. The better approach treats hydration as continuous replacement, not a single strategic dose. On events longer than three hours, that also means adjusting your Skratch intake as fatigue and heat accumulate, since your sweat rate in hour four rarely matches hour one. Consistent, planned intake beats sporadic big gulps almost every time, both for comfort and for avoiding the stomach sloshing that comes from drinking too much at once after a dry stretch.

What Do Athletes and Reviewers Actually Say About Skratch Hydration?

The consistent theme across athlete feedback and product commentary on Skratch Labs centers on gut comfort. Runners and cyclists who’ve struggled with stomach distress on traditional neon sports drinks frequently point to the real-fruit, lower-osmolality formulation as the reason Skratch sits better during long efforts, a claim that aligns with the brand’s own positioning around gut tolerance.

The flavor profile draws mixed but generally positive reactions. Because Skratch skips the intensely sweet artificial flavoring found in many competing mixes, some athletes coming from sweeter drinks describe the taste as subtle or even bland on first try, while long-time users tend to describe that same subtlety as easier to drink consistently over several hours without palate fatigue setting in.

On effectiveness, the sodium and carb numbers hold up against standard sports nutrition targets, which is a big part of why coaches and dietitians treat it as a credible option rather than a lifestyle brand riding on packaging alone. The most common critical feedback isn’t about the formula itself, it’s about cost relative to store-brand electrolyte tablets, a fair trade-off consideration for athletes training on a budget who don’t need the real-fruit flavoring to hit their sodium targets.

An Editor’s Take on Choosing the Right Skratch Mix

Most athletes overthink this decision. If you’re doing anything from a tempo run to a half-Ironman in reasonable conditions, Sport Hydration Drink Mix covers it, and you don’t need to shop further than that.

Where it gets interesting is at the extremes. Heavy sweaters doing long, hot rides benefit from pairing Sport Hydration with an Electrolyte Booster scoop rather than just drinking more of the standard mix, since that keeps sodium climbing without dragging sugar intake up alongside it. Ultra-distance athletes chasing carb targets above 60 grams an hour are better served combining Super High-Carb Mix with gels than trying to hit that number through drink mix volume alone, which just means drinking uncomfortable amounts of fluid.

My practical suggestion: test any new flavor or SKU on a training day at race-pace effort, never for the first time on race morning. Gut tolerance to electrolyte drinks varies enough between individuals that what works for a training partner can leave you queasy at mile 18. A $6 packet tested three weeks out beats a race-day surprise every time.

FAQ

Is Skratch good for hydration?

Yes. Skratch Sport Hydration Drink Mix provides roughly 400 mg of sodium and 19 to 20 grams of carbs per serving, which lines up with standard sports nutrition targets for sessions over 90 minutes. Its real-fruit formulation also tends to sit easier in the gut than many artificially sweetened alternatives.

Is Skratch Labs worth it?

For athletes training or racing longer than 90 minutes, the sodium and carb balance justifies the cost over plain water or unflavored electrolyte tablets. If your sessions are short and mild, a cheaper unsweetened option or plain water may cover your needs just as well.

How often should I use Skratch hydration?

Start with one serving per hour for sessions over 90 minutes, and increase toward 1.5 servings per hour in heat or heavy sweat conditions. Shorter, milder sessions generally don’t need it at all.

Why does Skratch have so much sugar?

Skratch’s carbohydrate content, around 19 to 20 grams per serving, isn’t excess sugar, it’s fuel calibrated to endurance sports nutrition targets of roughly 30 to 60 grams of carbs per hour for long efforts. The Unsweetened version removes carbohydrate entirely if you only need electrolyte replacement.

What’s the difference between Skratch Sport Hydration and Unsweetened?

Sport Hydration includes both electrolytes and carbohydrate for fueling during activity, while Unsweetened provides sodium and potassium without any added sugar. Choose Unsweetened for low-intensity sessions or when pairing with solid food.

Can I mix Skratch with energy gels during a race?

Yes, and many endurance athletes do exactly that on long or ultra-distance events. Pairing Skratch’s fluid and sodium delivery with a GU Energy Gel lets you hit higher hourly carbohydrate targets without over-concentrating your drink mix.

How do I know how much sodium I personally need?

Run a sweat-rate test by weighing yourself nude before and after a representative one-hour session without drinking. That weight difference, converted to fluid volume, tells you your baseline sweat loss and helps you calibrate sodium intake using the 300 to 700 mg per hour range as your guide.

Is it safe to drink Skratch during hot weather races?

Yes, and it’s often more important in hot conditions since sodium losses through sweat climb with heat and humidity. Consider adding an Electrolyte Booster scoop to your Sport Hydration mix rather than just drinking more plain water.

Where can I buy Skratch Labs hydration mix in Singapore?

Racepack SG carries Skratch Labs Unsweetened Hydration Sport Drink Mix in 10 and 20 pack sizes with guaranteed authenticity and next-day delivery within Singapore. Current pricing is listed on the product page.

Can drinking too much Skratch cause hyponatremia?

Hyponatremia is far more commonly caused by drinking excessive plain water without enough sodium, not from properly dosed electrolyte mixes like Skratch. Watching for unexpected weight gain during a race is a reliable warning sign you’re over-drinking relative to your sweat losses.

What’s the shelf life of Skratch hydration mix once opened?

Skratch doesn’t publicly list an exact opened shelf life on its packaging, so check the resealable bag’s printed date and store it in a cool, dry place away from moisture. If the mix clumps or smells off, it’s past its useful window.

Should beginners start with Sport Hydration or Unsweetened?

Beginners doing sessions under an hour can often skip electrolyte drinks entirely and stick with water. Once training sessions regularly exceed 90 minutes, Sport Hydration is the more practical starting point since it covers both sodium and carbohydrate needs in one mix.
