I like this product and I think it's working great,and also it tastes good.Product has terrific flavor, I use before I exercise particularly on hot summer days for hydration. The product does not fully dissolve, so there are granules left at the bottom creating a bit of a gritty solution towards the bottom that is unpleasant to consume.Love the flavor and a great way to get aminosI have several electrolyte powders and I have also tried premade in bottles (which is more expensive and takes up a lot of space in my pantry) all of them irritated my stomach because they load it with citrus. They also do not contain the amount of electrolytes and minerals I need. This one does and doesn’t irritate my stomach. I bought the blue, has a nice berry flavor. Wish they made a mango peach though. I have issues with low potassium, magnesium and electrolytes due to gastric bypass years ago. In this very hot summer this year and having to do a lot of work outside I was suffering. This product has been a big helpOMG the flavor is crazy good!! It mixes very well and doesn’t clump. Found my new favorite!Just the right amount of caffeine to get your morning workout going. Shake well. It can clump up.Read the instructions !!! It’s gonna save soo much confusion for first time usersIt taste like chemicals/chalky I’m sure this item is either a bad batch or expired. Usually the taste is yummy and I have no complaint.
