I have used High5 tablets for a couple years and have liked them but the price keeps going up and I have to order from the UK. I have also used Hammer Gel's and Heed for a long time and thought I would try Fizz. I think they are better than High5 just a little more expensive.
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.
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.
Hammer tabs have a nice mild flavor and sit well on my stomach during long rides. They're also good for post-ride hydration and encourage me to drink more than I might otherwise (unless I feel really thirsty). Prices are fair compared to some other brands, but BTD offers bulk discounts and occasionally puts the tabs on sale.
The Hammer fizz tabs have a nice mild flavor (I tried mango, cola, and grape), and don't cause the gastric upset I feel from other similar products. They also contain high levels of minerals like magnesium and vitamin B6, which is good if you sweat a lot or are concerned about hydration and maintaining electrolyte balance.
I just wish Hammer sold their tabs in bigger, higher count tubes like SIS or High 5. I re-use the empties for various things, but a lot of plastic still winds up in the recycling bin.
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.
