If your really interested in getting a full meal packed with that extara protein with the least amount of sugar compared to other..., umm, protein bars out there - this is by far the best protein bar out there. I highely recommend it!


Too much fat and too much sugar. It's 32g protein but it's way too much sugar and fat. I've tried myprotein cookie and it's more protein (37.5g/cookie) and less sugar (7g/cookie) and less fat (10g/cookie) and also cheaper with the deals (buy one get one or 50% off )

I normally buy these from the local grocery but they don't have this particular flavor - I decided to throw in a few and glad I did, these were delicious! I'm not extremely picky and enjoy all the flavors though. Very filling bar, definitely a suitable meal replacement.
