Have researched this product.In the past I have experienced problems cramping up.Not a problem since using Hammer Fizz. Have used other Hammer products also including Hammer Whey and currently using Hammer Recoverite.
These tablets are very easy to use and have an OK taste- not as goos as gatorade, but probably because there's less sugar... haven't had any leg cramps since using, not sure if that's coincidence or what...
I put one tablet in a 22 oz bottle and sip as needed before and during a ride after it has dissolved. Found it is best not to add any other carb or electrolyte mixes, just water. I use a gel as carb fuel or a snack bar. So far I have only tried the grapefruit which has a very light pleasant taste, not sugary at all! No problems with cramping or bloating that I have experienced with powdered mixes. Recovery seems easier too! Good price value.
Have been using Fizz for over 5 years, and I swear by them. When doing extreme workouts in the heat, I will notice I get dizzy when sitting and then standing, this lets me know I am off on my electrolytes. Pop one in a glass of water and soon everything is back in order. Taste is good.
I've been using these for years. I take them out on long rides and when it's time to refill my water bottles, I buy vitamin water - there are 2 mango flavors - add a fizz mango and you get all the electrolytes (from the fizz) with some sugar and vitamins from the vitamin water.
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 am a heavy sweater and need lots of sodium. I put two Fizz in a water bottle and supplement with capsules. Lime Lime and Grape are my two favorite flavors. Had stomach issues with other products - but I do randonneuring, so 12-18 hours on the bike can put stress on digestion.
I ordered this to cut out the carbs from sugar in the average sports drink. The sweetness of powerade or gatorade almost gagged me once it had warmed up. This is not so sweet like that and is palatable while warm.
However keep in mind, you will need to replace those carbs in other ways on longer rides. Wish it came in a caffeinated version!
