    A game changer product in the bar market – no other bar competes with these nutrition facts! And to top it off, the peanut butter flavor is amazingly delicious and so easy to eat. I plan on buying these for life!

    Had one of these each morning on a week long bicycling trip in June. Provided fuel without stomach upset and got me to a later breakfast or lunch down the road. They are my new bike trip staple and plan on taking them this fall when I bike from DC to PIttsburgh!

    The taste/texture is not great, they’re very gummy and don’t taste like much. I’ve also gotten bad stomach aches every time I’ve eaten one. I much prefer Raw Rev Glo bars.

    These Fiber Protein bars are very tasty. I like the Peanut Butter and the Chocolate Brownie so much I ordered extra boxes and sent some to my daughter. They are perfect for her busy lifestyle & she takes them with her when she travels.

    could be better. I bought peanut butter bar, chocolate bar, and 2 of the vanilla protein powders during the last promo.
    I left a review under the chocolate bar saying these bars weren’t as filling as advertised (for me at least vs other bars) and that these bars are grainy and taste very artificial. I also said I wish this I could leave a raving review about the bars since f factor diet helped me lose my pregnancy weight, but I guess this wasn’t a good enough review because it was never posted after review. lol.
