When choosing a protein bar, you should aim high in the protein department. Protein is great for boosting energy and, of course, building muscle.

Though they may not have the same level of name recognition as other protein bars, these whey protein bars from Detour consistently top the list of the best ones. The 370-calorie bars each pack a whopping 32 grams of protein, and they also tout 21 vitamins and minerals as well as 100 mg of Omega-3. They also contain sugar alcohols, which can cause bloating.

They come in three flavors—cookie dough, cookies n’ cream and peanut butter, and most customers say they taste great. They also work well as a heavy post-workout snack.

In addition, rise bars are crafted and packed in-house daily (so you know you’re getting all the good stuff!) and are super easy to digest (they don't contain any sugar alcohols).
