Now I know why this one was so cheap! The taste was not pleasing to me at all... I threw it away. However, I do love their other lines, with the berry flavor being the best! Orange is good too but to obtain the best flavor, 2 spoons are required (for me anyways). Also, the berry flavor (while only taking 1 spoon) is even better tasting if you add a little lemon juice to it. Finally, I read that adding lemon juice to water helps to prevent kidney stones! Who knew! This is a good product but I think they went to far trying to add "fizz".... the effect was negative while the previous products are great!
