You'll get fast cramp relief from CrampFix's 50ml shot, which uses acetic acid to trigger a sensory nerve response in your mouth and throat. That response shuts down the overactive signals behind cramp. One 50ml bottle holds three to five serves, and there are six in the box. **Product Highlights** ??? 50ml bottles across a six pack supply up to 30 doses, enough to cover a full training block ??? Acetic acid works through the nervous system rather than rehydration, so relief lands in 30 seconds to two minutes ??? Informed Sport 'Trusted by Sport' certification, with every batch independently tested for banned substances ??? Water, vinegar, sugar, salt, potassium, calcium and magnesium: natural, gluten free and vegan ??? Small 15 to 20ml serve does the job, against the 75ml of a pickle juice fix **Best For** ??? Ironman and long-distance triathletes fighting cramp on race day ??? Trail ultra runners hours deep into a 100km push ??? Competitors under anti-doping testing who need every batch tested
