Rated 5 out of 5 by from The best. This is absolutely THE. BEST. TASTING. PROTEIN. BAR. EVER.
Date published: 2019-10-07
Rated 5 out of 5 by from Beyond all other Blueberry Walnut Protein Bars are the most satisfying meal bar I’ve ever tried. Keeps me full for hours, doesn’t weigh me down, and doesn’t spike my blood sugar, but satisfies a carb craving. I plan to order more so I can eat at least one daily as a meal replacement because they are only 250 calories and carrries all the basic nutrients your body craves. I know this sounds as if I’m a paid advertiser, but I’m not! Just a huge fan, and thankful!

Rated 5 out of 5 by from Vanilla Almond Protein Bar These bars are delicious. Perfect supplement to an active lifestyle. They don’t melt and provide nutritional calories in a pinch.
