The ONLY chewable tablet formulated to closely resemble the electrolyte profile lost in sweat: sodium, potassium, calcium and magnesium.

It helps reduce muscle cramping and heat stress, boost stamina, and maintain electrolyte levels. Chewable tablets provide fast absorption through buccal mucosa (tissue in the mouth).

  • Made in the USA — Free of banned substances and independently tested. Learn more about our manufacturing and safety.
  • Each serving (2 tablets) contains 100 mg sodium, 30 mg potassium, 10 mg calcium, and 6 mg magnesium.
  • Ingredients are non-GMO, gluten-free, vegetarian, and fat-free—natural stevia as a sweetener. No colour was added—bio-available active ingredients. 
  • Also great for youth sports, travel rehydration, tennis and other sports, camping & hiking, effects of alcohol.

How do I use them? 

It's in the name! FastChews are FAST-absorbing electrolytes designed to be CHEWed, not mixed with water. The electrolytes in FastChews are absorbed through the lining of your mouth, which studies have shown to take in nutrients 2-4x faster than the intestines. Chew FastChews or let them dissolve in your mouth; then wait 2-3 minutes before eating or drinking so the electrolytes have time to be absorbed into your bloodstream.


How often do I use them? 

Everyone is different, and your exact electrolyte needs will be based on your bodyweight, genetics, level of fitness, and outdoor temperatures. But in general, we recommend taking 1 FastChew every 15 minutes during exercise if you're consuming a sports drink, or 2 FastChews every 15 minutes if you're consuming plain water.

Energy fast chews

They never had any stock, I requested a replacement of the cherry flavour chews and they didn’t have any stock of that either, sent a different flavour with half the caffeine in them. Not the greatest experience but customer service was at least communicative and responsive. Wasn’t worth the hassle for ~$10 cheaper than other websites as after all the changes it took almost 3 weeks to come from initial order.

Perfect for dizziness

These electrolytes are brilliant for my teen daughter, who suffers from POTS (gets dizzy a lot) She loves the mixed Berry flavour, when very similar taste to red poweraide. Oz Backcounty are fantastic, super friendly and helpful and delivery is so fast.
