How crampfix mouth spray works


What is a muscle cramp?

A muscle cramp is a sudden and involuntary or contraction of one or more of your muscles. These contractions or spasms are painful and can occur in various muscles. The muscle or muscles get tight and do not relax. CrampFix can help relax these tight, contracting muscles.

What causes muscle cramps?

To date, nobody knows what causes muscle cramps. The common belief is that cramps are caused by a lack of magnesium, salt, or other minerals. It is also thought that a lack of hydration or a build-up of lactic acid can cause cramping.

How does CrampFix work?

CrampFix works rapidly to fix and prevent muscle cramps by targeting the overactive nerves that are causing the muscles to cramp. We don’t know exactly what causes muscle cramps but we know how to fix them! There is an association between premature muscle fatigue, exercise-induced muscle cramp, stimulation of sensory nerves, and interruption of alpha neutron (nerves) firing.

When should I drink CrampFix?

Drink when the cramp strikes or at first signs of cramp for rapid relief. If the muscle cramp is not relieved after a few minutes, repeat dose.

How much do I need to consume for it to work?

4 sprays of CrampFix into the mouth should relieve the cramp.

Where can I purchase CrampFix?

CrampFix is available at Woolworths in the pain relief aisle. If you have trouble locating it, ask a staff member for assistance.

We also sell CrampFix online here.

What is the scientific evidence behind it?

There are several key studies supporting the effect. Dr. Kevin Miller of Central Michigan University has conducted research supporting the beneficial effects of acetate and ‘pickle juice’. The first clinical trial was conducted on electrically induced muscle cramps (EIMC) which convincingly proved that ‘pickle juice’ successfully and rapidly reduces EIMC when compared with water as a placebo.

CrampFix is a highly effective formula that took three years to develop.

Why does CrampFix have a strong taste?

One of the main ingredients is acetate (vinegar) which has a very strong and dominating taste. Most people find they get used to the taste after using the product a few times.

What ingredients are in CrampFix?

The all-natural, gluten-free, & vegan formula has a specific blend of astringency and pH level that provides reliable and rapid relief for muscle cramps.

Ingredients: water, vinegar, sugar, salt, potassium, calcium, magnesium & natural flavor.
