Our Electrolyte Booster delivers customizable electrolyte support without any added sweeteners, flavors, or salty taste.  It mixes easily into your drink to boost your sodium, but not your flavor or carb intake.  Designed to work seamlessly with any hydration or fueling strategy, it lets you dial in exactly what your body needs—nothing more, nothing less—so you can stay hydrated and perform at your best.

Great for:

  • Higher sweat rates
  • Higher sodium loss (alt: When you lose more sodium than average)
  • Hot or humid conditions
  • Long training or race days

Start with adding ½ to 1 scoop (400 mg sodium per scoop) to 12–16 fl oz of any drink and shake.

Stack with Skratch Hydration Sport Drink Mix, Super High-Carb, or any drink mix option.

Dial it in based on your sodium needs and how you feel.

INGREDIENTS: Sodium Citrate, Citric Acid, Potassium Citrate, Calcium Citrate, Magnesium Carbonate, Ascorbic Acid.

“I’ve been using the booster to rehydrate after hot, sweaty rides and to preload for the summer races. I love that it’s unflavored. Adding it as an extra punch to the Sport Drink Mix or Unsweetened Sport Drink Mix has been a hydration game changer. It’s been helping me get the most out of my workouts and kickstarting the post-ride recovery.”

frequently asked questions

It’s a sodium-only hydration add-in — no flavor, no sugar, no calories. Designed for salty sweaters, hot days, and long, hard efforts where you need more sodium than what’s in our other hydration mixes. It gives you full control without changing your drink’s taste or carb load.

Electrolytes are minerals—like sodium, potassium, calcium, and magnesium—that help your body hold onto fluid, maintain proper muscle function, and keep your nervous system firing. When you sweat, you lose more than just water—you also lose electrolytes, especially sodium. If you don’t replace both, your performance can suffer. Replacing them helps you stay hydrated and perform better, longer.

If you’re a heavy or salty sweater (think white streaks on your face or jersey), or training/racing in heat or for long periods, you may need more sodium than you’re getting. Our Electrolyte Booster lets you add more sodium to your drink without changing your flavor, sweetness, or gut tolerance.

If you don’t know your sweat rate but want to see if you’re a salty sweater, start by paying attention to visible salt marks, post-workout salt cravings, or feeling dehydrated even when you drink plenty. You can also try the weigh-yourself trick: weigh before and after a workout. If you’re drinking to thirst and still losing more than 2–3% of your body weight, your drink likely isn’t salty enough to trigger enough thirst. In that case, adding Booster in half-scoop increments and tracking how you feel can help you dial in your sweet spot.

Booster was made to mix — not to be taken on its own. Always dissolve it in water or another drink. It blends seamlessly with our Sport Drink Mix (for more sodium without extra sugar), Unsweetened (for a low-flavor, high-performance base), or Super High-Carb (for when you need serious fuel and more sodium). You can also add it to plain water or other low-sodium drinks. Just avoid mixing it with drinks that are already high in sodium, and know that in strongly acidic liquids (like juice), flavor might shift slightly. If you add too much and don’t dilute enough... yeah, you might taste it.

Used as directed, it blends in seamlessly — no salty taste, especially in water or Skratch mixes. In more acidic drinks (like juice), or if you overload a small bottle, you might notice a subtle shift. But even then, it's milder than most salty-tasting products or salt tabs.

Start with ½ to 1 scoop (200–400 mg sodium) in 12–16 fl oz of water or any drink. Adjust based on sweat rate, workout length, and weather. Most athletes max out around 2 scoops per bottle. For preloading or extreme conditions, up to 4 scoops is possible — but taste and tolerance vary.

Try weighing yourself before and after a workout. If you’re drinking to thirst and still losing more than 2–3% of body weight from fluid loss, try increasing sodium with Booster (in ½ scoop increments) to encourage more drinking and better hydration. The goal is to stay hydrated just by drinking to thirst — when that happens, you’ve found your sweet spot.

Booster is just electrolytes — so you can customize based on your needs. No carbs, no flavor, no sweetness means you can boost sodium without overdoing fuel or messing with your gut.

Amazing

I used the electrolyte booster during a HR48 endurance test for my black belt. I couldn’t have done it without SKRATCH! Constant exercise, no sleep 15 mile 1600 elevation bike ride, constant exercise. SKRATCH made it possible to keep going for the 48+ hours.

What I've been missing

Found myself drinking too much on rides and not feeling great. Added the Booster to a regular bottle of Skratch and feeling better with each bottle and not slamming it as often to get the electrolytes I was craving.

Truly unflavored!

I put this in my plain water and I’m usually pretty sensitive to the “unflavored” flavor (it’s a thing), and I truly could not taste it at all. I was pleasantly surprised!

Another success!

Skratch continues to learn and make products that are a “W”! This is a great boost of electrolytes that are easy to take in! Sometimes flavor fatigue is real and you still need electrolytes- this is the secret sauce!

POTS relief

I have recently been diagnosed with POTS as well as MCAS and had to up my intake in water as well as sodium, the fact that there is 400mg in each scoop is amazing and something I have struggled to find especially without a lot of additives and filler. This is the cleanest electrolyte supplement I have found so far and since trying it for the first time about 3 months ago I have loved it and not looked back. This does seem to help a lot with some of the symptoms I get with lower sodium and helps with that and hydration which I absolutely love. I truly cannot recommend this or the unsweetened hydration electrolytes enough from ya'll.
