Hard to mix
I tried the Vitargo based on word of mouth. It seemed to go a good job of providing steady energy for long runs and I had no stomach discomfort at all. Unfortunately it was so hard to mix that I wont use it again. It was very clumpy and even bogged down my tiny blender which I successfully use for all of my powdered supplements. The frustration far outweighed any benefits and there are other similar drinks available that mix much more easily. Disappointing.
