My work is extremely hot and humid, walking stairs for 8 hours near pasteurizers (water ovens). In the summer in Houston, it's regularly 100+ heat index in there. I drink a minimum of 1 gallon of water, often two gallons, and occasionally get into my third before an 8 hour shift is up. Over the years I've tried pretty much every electrolyte product on the market and am so happy to have found these. The flavors are exactly what they sound like. Kinda fruity flavor with a ton of salt. I'll add them to 48oz of water, sometimes with another supplement like collagen for my knees. They kick pretty hard with less than 16oz of water but taste quite nice over a bigger volume. I drink one of these a day in my first half gallon and rarely get dehydrated. Often times on the weekends, or if I get more than one day off in a row, I'll wake up with deep tissue muscle cramps, usually from the inside of my knee to my groin, with no easy stretch available to help. It's the worst, so bad it often sends my body into shock giving me an instant fever and dizziness when I need to be upright stretching lol. Since I found these, I'll try my best to hobble to the kitchen, drop one into a 16oz water bottle and chug it fast. It's crazy how fast it helps, like within ten minutes the cramp is nearly gone, manageable. Truly a life saver. Won't recommend anything else to others.
