While there are a few reviews of the taste of this product that are not so stellar, it is amazing how many people truly love the taste. It has been stated a plethora of times that consumers feel as if this is one of the very best tasting protein-boosting bars available. There are not many that find it overly sweet and it does not seem to leave that artificial aftertaste in your mouth like so many protein bars, pre-workouts, and protein powders usually do. We were also happy to see that the taste of each flavor is what you would expect it to be. We say this because so many options have very little flavor or taste nothing like they are intended to.


Having the option of several different flavors is beneficial for a couple of reasons. First, it will ensure you are able to find one that you really love the taste of.

These bars are chewy and also contain a crispy element that will please your pallet. It is important to note that if they get too warm they will start to melt and become quite sticky.

There are a couple of aspects of effectiveness that need to be discussed when considering this product. As a meal replacement bar, this product is very effective. It contains plenty of calories to substitute your meal and will give you the energy you are looking for to ensure you don’t need a bunch of snacks before your next one.

If you are on a serious sugar restriction then you may find this to be too much but more often than not people can fit in with little effort.
