I bought this for my incredibly active 76 year old grandmother who frequently works outside in her garden, on top of working full time. On average she burns 1200 calories a day or more. She could not stand the salty flavor of pedialyte or the sweetness of Gatorade. She complained of leg cramps at the start of this summer so I quickly searched for a solution. She loves these, and is now on a monthly subscription. I would recommend these to anyone suffering from dehydration!
