Review on Amazing Grass Vegan Protein & Kale Powder: Organic 20g Protein + 1 Cup Leafy Greens, Mixed Berry Flavor, 15 Servings by Christine Sanchez

First, the flavor is decent (berry) but it didn't go smoothly - quite chalky and gritty. I had an upset stomach the first time I ate it. Thinking it was just an accident, I ate it again the next day. Unfortunately, I had the same indigestion, only the pain was worse and lasted for several hours. I don't know what caused such a reaction in this product, but I won't be using it again.
