For those of us on a low carb diet these little tablets are just the thing.  Two years ago I started cycling again after many years but was having heart arrhythmia after longer rides in high heat.  I was drinking plain water but did a little research and thought electrolytes might be the issue.  Gatorade wasn't an option because it is so loaded with carbohydrates so I looked around for a low-carb alternative.  The "zero carb" sports drinks didn't help so what to do?  One day I ran across these at my bike shop so tried a tube of them.....voila!...problem solved!!  I've shared them with two friends in particular whose problems with leg cramps were resolved while using these.  These guys got it right -- they are superbly formulated and simply work.....

These are wheat thins, with some flavor added. The Flavor is very salty, and you can definitely taste the MSG that they added as a cheap way to spike the flavor. As far as i remember, you can't really taste the basil at all.

I admit that I fully expected to dislike this product, and approached it with a dismissive attitude - something that's this trendy can't be any good, right? well, I was wrong. The ONE coconut water is refreshing, delicious, and just barely sweet. Really wonderful stuff. The hint of pineapple adds a little bit of acidity that enhances the basic taste of the water. i bet this would make a great summer drink too, but I only had one so I didn't get tot try that. My problem now is that it's been out of stock, so I can't get more.
