SaltStick FastChews quickly replace the electrolytes you lose in sweat to help support hydration, prevent muscle cramps, and reduce fatigue.

Because you chew them, the electrolytes begin absorbing through the tissues in your mouth before reaching your stomach. In a clinical study conducted at Western Colorado University, SaltStick FastChews started delivering electrolytes in as little as 45 seconds, with nearly 50% of sodium absorbed within the first 60 seconds.

That makes them one of the fastest and most convenient ways to support hydration before, during, or after exercise: No mixing, no waiting, just chew!

1. When should I take SaltStick FastChews?

Most athletes take 2 tablets every 30 minutes during exercise, depending on sweat rate, heat, and workout intensity. But you can take SaltStick FastChews before, during, or after exercise depending on when you need electrolyte support. They are especially helpful during long runs, cycling, hiking, travel, hot weather, and heavy sweating.

2. Do SaltStick FastChews help prevent muscle cramps?

FastChews help support electrolyte balance during exercise, which may help reduce muscle cramps caused by dehydration and heavy sweating.

3. Can FastChews be dissolved in water to create a sports drink?

SaltStick FastChews are designed to be chewed, not mixed into water. Because you chew them, electrolytes can begin absorbing through the tissues in your mouth for faster delivery compared to traditional powders or sports drinks.

4. How many FastChews equals one SaltStick Capsule? Why is the electrolyte concentration lower?

Approximately 4 SaltStick FastChews provide the same electrolyte content as 1 SaltStick Caps capsule. FastChews contain smaller amounts of sodium, potassium, calcium, and magnesium per tablet so you can take electrolytes in smaller, more frequent doses during exercise.

5. How should FastChews be stored?

Unopened packets or bottles of FastChews should be stored at room temperature in dry conditions for the longest shelf life. Opened packets and bottles should be kept sealed and used as soon as practical to help protect the tablets from moisture and humidity.

6. What happens if FastChews get wet?

FastChews are sensitive to moisture because salt naturally absorbs water from the air. If exposed to humidity or water, the tablets may begin to soften, discolor, or fall apart.

This does not affect safety or performance, but it can make them harder to consume. Sealed packets and bottles are moisture-resistant and designed to handle normal sweat and exercise conditions.

7. Do I need to take FastChews with water?

FastChews can be taken with or without water. They are designed to help replace electrolytes lost in sweat, while water helps replace fluid loss. This means you can drink when you need hydration and take FastChews when you need electrolytes.

8. Can I suck on FastChews or do I need to chew and swallow?

You can chew SaltStick FastChews or let them dissolve slowly in your mouth.

Because FastChews absorb through buccal tissue (the tissues inside your mouth and under your tongue), electrolytes can begin delivering quickly even before reaching your stomach. For best results, let FastChews dissolve fully before drinking water.

9. Why is sodium citrate used rather than sodium chloride?

For athletes with sensitive stomachs—especially during intense exercise—sodium citrate is often easier to tolerate. It also tastes less salty than table salt (sodium chloride), which improves flavor and usability during workouts.

10. Are FastChews considered organic?

15. My FastChews show brown spots or discoloration. What’s wrong?

In warm or humid conditions, ingredients in FastChews can react naturally through what’s called the Maillard reaction, which may create white or brown spots on the tablets. This is harmless and does not affect product safety or performance. We recommend storing FastChews in cool, dry conditions to help prevent discoloration.

16. Do FastChews contain sugar or sweeteners?
