CRAMPFIX FAQ

VIEW ALL FAQS →
Unlike standard electrolytes that must be digested and absorbed into the bloodstream, CrampFix works neurologically. The highly concentrated, low-pH formula triggers sensory nerves in the back of your throat, sending an immediate signal to your spinal cord to stop the muscle from violently over-firing.
You only need a very small amount. A standard dose is just 15ml to 20ml (about one large sip). Because it works by stimulating the nerves in your mouth and throat rather than physically hydrating your muscles, drinking more than the recommended dose will not increase its effectiveness.
No, swallowing is not strictly necessary. Swishing 10ml to 15ml of the liquid around your mouth and the back of your throat for a few seconds and then spitting it out is often enough to trigger the neurological reflex. However, swallowing it is completely safe and is the most common method during a fast-paced race.
It is highly effective for both. You can take a 15ml sip about 10 to 15 minutes before a heavily demanding section of your race (like a steep, out-of-the-saddle climb or the final 10km of a marathon) as a preventative measure, or you can take it the exact moment you feel a muscle lock up for emergency rescue.
No. CrampFix is a specialized, acute tool to stop muscle misfires, not a general hydration solution. You still absolutely need to maintain your normal carbohydrate and electrolyte fueling strategy (via bidons or gels) throughout your entire race to prevent systemic dehydration and fatigue.
Because the formula is designed to deliberately "shock" your sensory nerves, it has a very strong, astringent, and sour taste—similar to highly concentrated pickle juice or a strong vinaigrette. It is meant to be highly stimulating rather than a refreshing sports drink, so expect a sharp, sharp kick!
