These bars are not too bad. Good flavor and doesn't taste like cardboard.

  • 7 Peanut Butter Caramel Crunch

The problem with this bar is not the taste, it is trying to consume it. The caramel sticks to the packaging and makes extremely hard to eat.

One of the best tasting, if not the best tasting, protein bars that I’ve had. I love these for an on-the-go breakfast or I’ll split half between my pre workout and post workout snack.

Read the label: you are buying mainly Soy Protein Isolate - this is the first ingredient in the list. If you are looking for soy protein than this is the right protein bar for you. Otherwise - keep your money for better protein bars with better protein sources

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 )

  • 10 Chocolate Toasted Almond

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.

  • 10 Super Cookie Crunch

These are great. I love the cookie crunch ones. Also I read in the nutrition facts that theses are also packed with vitamins like A, B-6, B-12, C, E, and stuff like Calcium, Magnesium, Zinc, and Copper. On top of the 32 grams of protein. I will (just like everyone else) mention the 26 grams of sugar per bar which to me is the only downside. I love em though. I eat one every morning with a cup of coffee.

I have been using these bars as my lunch (along with cottage cheese and sometimes baby carrots) for a number of years. They are quite filling and tasty, particularly the apple pie and the chocolate toasted almond.

I'll just tell it straight - these bars are sugar-filled, delicious, and have sufficient protein. Anyone looking for something more than that should look elsewhere. Apple Pie is by far the best! I have one almost every day. PB Pretzel is really good too but a tad syrupy. And Cookie Crunch is not good. Don't know why it's rated so high.

Look guys, this stuff tastes great. But heed the warning about Sugar Alcohols.
