I'm always a bit skeptical about trying electrolyte powder but today was a very hot day and I needed one. I was very surprised, first of all, when I realized that mixing it is very easy and will not leave any residue on the bottom of your cup/bottle. The taste and the aftertaste are actually very toasty. I love the mix of essential vitamins B3, B5, B6, B12, C & E. I will certainly buy it .
