I hope that the reviews will be useful and helpful to you. I can tell you that I have tried a lot of different protein bars and I can say that they are all excellent. It's all based on personal experience, which means the reviews here are a very good guide to what is actually going to work.
The Best Protein Bar: The best protein bar you can buy is the one that is made with high quality ingredients and is 100% USDA certified Organic. That means the ingredients must be certified organic so that the protein in the bar is not contaminated with GMO's or pesticides. The ingredients in the bars should be organic and also free from BPA, phthalates, artificial colors, and GMOs. There are plenty of high quality protein bars on the market that use the highest quality ingredients and don't use GMOs. However, if you want the best protein bar, the one you need to buy, look no further.
A Note on BPA: BPA is used in food manufacturing, including making foods and drinks, and is a known carcinogen. While BPA in milk is usually not a problem, it is a concern when a child drinks a protein bar containing BPA, since BPA is easily absorbed into the bloodstream and can accumulate in the liver.
