Cold-FX is available for purchase in many Canadian grocery and healthcare outlets, though through their website they provide links to two online retailers, feelbest.com and well.ca, which will ship internationally.
Cold-FX is taken at the onset of cold and flu symptoms, and through many clinical trials has been shown to help reduce the length and severity of symptoms. Their website, cold-fx.ca, provides a plethora of testimonials from customers and doctors alike. It also features a social media tool that shows anyone tweeting with their company hashtags. Cold-FX does not cure the common cold, however, and in cases of bacterial infection it should not be taken instead of antibiotics or other doctor-prescribed medication.
