FastChews are ideal for anyone who sweats, including athletes and outdoor workers, or in situations where you need a boost of electrolytes.*

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.

The 'fast' in FastChews

The secret to our FastChews is the quick-dissolving tablet formulation. FastChews kickstart the electrolyte absorption process by entering the bloodstream through the ​lining of your mouth, which studies have shown to absorb nutrients 2-4x faster than through the small intestine.

What Athletes Have to Say

Amy D

“SaltStick Fastchews are my go-to for avoiding cramps during long distance runs. They definitely saved me during my 50k ultramarathon where I was out on hilly trails for over six hours non-stop. I love that they taste great and are easy to digest with or without water.”

Amanda G

“SaltStick FastChews are life-saving. After a horrible execution of 26.2 miles in hot and humid conditions then ending up in the end tent post finish line from dehydration, I discovered SaltStick as a to intake more sodium while training.”

Carrilyn R

“I started using FastChews during marathon training when I was having issues with calf cramping. They are incredible and absolutely work with the cramping. I highly recommend them if you are experiencing any calf or leg cramps.”
