Very firm small pieces with an intense licorice flavor. I love black licorice and have been trying different gluten free options. I will be ordering more of this one.

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.....

Well I have tried many protein shakes and the taste is never been a problem for me but this was just horrible. It's GOOD for YOU but I just couldn't do it. It might be a good protein shake but it's extremely salty, i tried to drink it with other liquids to help the taste but every time it tasted worse and worse =( too bad because I was looking forwards to see some results!!
