SaltStick FastChews are like little supercharged sweeties for sweaty people!
They’re chewable tablets that deliver electrolytes – namely sodium, potassium, calcium, and magnesium – the minerals your body loses when you sweat.
Imagine you’re out on a long run, cycle, or gym session. You’re sweating buckets. Not just water, but also the salty goodness your muscles need to work properly is leaking out of you.
If you don’t replace it, things start to go wrong: Cramps attack like angry ninjas – energy crashes like the WiFi in Starbucks – and you start questioning your life choices!
You pop one (or two), chew them patiently, and boom – your body gets the electrolytes it needs to: (1) Keep muscles working properly, (2) Avoid cramping, (3) Stay balanced and comfortable.
Chewing helps get the ingredients into your bloodstream faster – some even absorb sublingually through your mouth.
Who it’s for:
Ideal for anyone doing endurance sports, training in hot conditions, or needing fast hydration on the go – runners, bikers, hikers, travellers, or even anyone struggling with heat stress or hangovers.
What it does:
Delivers electrolytes (Na, K, Ca, Mg) matched to sweat loss via chewable tabs that absorb quickly in your mouth – helping prevent cramps, maintain stamina, reduce heat stress, and rehydrate almost instantly.
How I would use it:
Chew two tablets every 15-30 minutes during long workouts or hot days. Let them dissolve in your mouth before swallowing and sip water alongside as needed. Toss a packet in a shorts pocket or glove box – ideal for mid-ride, mid-hike, or wherever sweat hits you the hardest.
The Science
SaltStick FastChews Clinical Study (Western Colorado University)
Study: A clinical study measuring how quickly sodium and potassium from FastChews are absorbed via buccal (mouth) tissues compared to traditional sports drinks or powders.
SaltStick & Western Colorado University, published via Endurance Sportswire and SaltStick blog (2025)
FastChews deliver nearly half of their sodium and significant potassium directly through mouth tissues in under a minute – much faster than digestion-based drinks.
This rapid uptake is ideal for combating cramps, fatigue, and heat stress during intense activity.
Enhanced Sodium Absorption via Sodium Citrate (Animal Study)
Study: An in vivo rat study exploring how sodium citrate enhances the absorption of sodium and water in the intestine versus other formulations.
Journal of Pediatric Gastroenterology and Nutrition (1990)
https://pubmed.ncbi.nlm.nih.gov/2246723/
Sodium citrate significantly boosted sodium and water uptake compared to non-citrate solutions. Since FastChews use sodium citrate as their sodium source, this points to more efficient electrolyte absorption and support for quick rehydration.
