CrampFix’s proprietary formula has been created to contain just the right blend of astringency, pH, and mineral content to provide rapid relief.

 

CrampFix is a no-mix, liquid formula that provides an almost immediate effect to get rid of cramps that most commonly appear during endurance activities. And if you’re someone who suffers terribly with cramp (as I do when doing any endurance based activity), you’ll know that this should be an essential item in any kit bag.

 

CrampFix uses the latest research using the TRP Channels to control your muscle cramps. By activating the sensory nerves in the back of your throat, CrampFix treats muscle cramps neurologically and provides almost immediate relief within 30 seconds to 2 minutes. It works as an acute sensory stimulant to oral-pharyngeal reflexes.

 

Warning: This product does not taste great – but if your in the throes of a bout of cramp, you’ll know that you’re not exactly in a position to savour taste anyway – you just want out of pain…. and fast!

 

Available in two flavours:

 

Lemon – strong and sour, salty vinegary taste.

Raspberry – strong but sweet and salty vinegary taste.

 

Who it’s for:

 

Perfect for endurance athletes, long-distance runners, cyclists, or anyone struggling with acute cramping mid-session—or even night-time leg cramps in active individuals.

 

What it does:

 

Think of it as a “cramp‐kill switch”: the sharp vinegar taste triggers a nerve reflex that tells your muscles to stop cramping—often before electrolytes or fluids aid recovery. Almost like flipping a circuit in seconds rather than waiting for hydration to catch up.

 

How I would use it:

 

Tear open and take the full 20 ml at first notice of tightness – or sip 10-20 ml before intense activity to pre‑empt cramps. Swirl in your mouth momentarily before swallowing if the taste’s too strong – it still works. One sachet usually keeps cramps away for 30-40 minutes. Max 100 ml per day.

 

 

 

The Science:

 

Fast cramp relief by triggering an oral reflex – without electrolyte changes

This placebo-controlled trial showed cramps stopped an average 49 seconds faster after participants drank pickle juice vs water, without changes to blood electrolyte levels – supporting CrampFix’s rapid relief mechanism via sensory nerve activation.

 

 

 

 

Electrolyte-rich hydration reduces real-world cramp incidence in endurance athletes

In an open survey of 184 half-marathon runners, those who hydrated with a magnesium-rich electrolyte mix (100 mg magnesium per serving plus sodium and potassium) had 46% fewer cramp incidents than runners using water only. Cases of severe cramps dropped from 20% to just 9%, demonstrating how balanced electrolytes – including magnesium – support muscular stability and reduce cramp severity.
