I have always suffered from severe acid reflux and indigestion often very severe and have used several prescriptions and over the counter meds to treat my condition. I had heard that extreme X2O could aid in relieving me of these symptoms so after about a month of using the product, I realized that my acid reflux had absolutely disappeared. This alone has been such a relief for me, if I miss a day or two without using the product, I can definitely tell the difference. Additionally, the hydration that extreme X2O provides is amazing, as a volunteer firefighter, I noticed that during intense trainings, and even during our last incident, I did not get the normal muscle cramps, and soreness that usually comes with this type of intense workouts. It is simply amazing as to how something as simple as a little sachet added to your water can change your life! Thank you Xooma!
