I have been using John Ellis water now since I was 16, and I am now 34. I have used it to help my running and athletic performance, and I think it has worked well. My father purchased his first John Ellis Purifying Distiller more than 18 years ago. I enjoy the taste of the water, and I also mix the pure distilled water regular filtered water to energize it. This helps extend the life of the John Ellis living water. I drink it while I work out, and I also feel like I still have a lot of energy even when I do not get a full night of rest. I also use it as a way to detox the body from chemicals that are in the air, and it the food we eat. I use the John Ellis Water for cooking, coffee, and any other recipes which require water as an ingredient.
