Mixed Berry Bliss Quest Bar Review (New Corn Fiber Type)

All Quest Bars are made of high quality protein and have plenty of fiber, but these days that’s not enough. Food tech has advanced to the point that a nutrition bar must also be delicious to be called the best. So in this review I’ll let you know how the Mixed Berry Bliss Quest Bar tastes, and what difference the new fiber type has made.

Mixed Berry Bliss Quest Bar


The official description from Quest’s website:

Unwrap the pure bliss of mixed berries and dreams come true, with an added 20g of protein! Try the Mixed Berry Bliss Quest Bar and you’ll wish they grew on bushes, too.

It’s an uncoated, berry-flavored protein bar. This is what it looks like:

Mixed Berry Bliss Quest Bar, no wrapper

Taste & Texture

It’s sweet, softly chewy, with bits of dried blueberries and strawberries providing a good berry flavor. The berries and their seeds add nicely to the overall texture, and I was surprised at noticeable bits of almonds, too (considering they’re not mentioned in the name of the flavor).

It was much nicer than I remembered it being when I tried the first iteration of it years ago. That’s probably less because they’ve had a major recipe-change, and more my memory being inaccurate, though.

This is a really nice Quest Bar. I normally opt for the chocolate chip varieties over it, but it’s great for a change.

As with all Quest Bars it’s great as it is, but it’s even more rich and dessert-like heated about 10 seconds in a microwave or baked a few minutes (which is even better because the outside goes crispy).

Corn Fiber Recipe Update

Quest Nutrition built their reputation with IMO (isomaltooligosaccharide) fiber as a main ingredient in their bars. They’ve since removed IMO from their line up entirely and now use corn fiber instead, claiming it makes a softer, longer-lasting product.

The IMO version could get quite tough towards the end of the use-by date. The updated Mixed Berry Bliss Quest Bar I had was noticeably softer, and the new fiber type seems to be a big improvement texture-wise.

(Weights of Quest Bars can vary quite a bit, leading to significantly different caloric content than stated on the label. I did a write-up here.)

Mixed Berry Bliss Quest Bar Rating: 8/10

This is a good flavor. As mentioned, I normally choose chocolate chip varieties over this one, but I like this for something different occasionally.

Thanks so much for reading. If this was useful, I have reviews of all Quest Bars here.
