These are basically Fizzies from the 1960s1970s. Can't say whether or not they help with cramping, since I don't cramp often enough to prove they kept cramps away. They taste okay and give some salts, but I will probably not be buying them again.
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.
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.
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've found the Hammer Fizz to taste quite bad in comparison to Nuun. I just had a Lemon-Lime and it tasted terrible.
I cant comment on the nutritional/electrolyte content between Nuun and Hammer Fizz.
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...
