I have a hard time staying hydrated on weekends. Drinking lots of water helps to an extent, but I often find myself cramping (quads) during Sunday night soccer games. Then I gave these a try. No more cramps and it tastes good. I've tried the grape and grapefruit so far and they're both good enough that my 3.5 year old thinks he's getting a special treat when I let him have some.
Overall I'm impressed with every Hammer product I've tried - I especially like how they justify their ingredients with scientific studies and leave out as much as possible.
I have been using these cramp busters for a few years. My favorite is the grapefruit flavor. I haven't had a problem with leg cramps since I started using them. If i have a cramp, these will relieve it in less than two minutes.
These are a staple of my training when exerting all youve got. I add 1 and a half of these tablets to my 25oz water bottle along with 1 scoop of Skratch sports powder and boom you feel rehydration running through your body ready to continue turning up the heat.
