The FDA has not established a formal definition for “natural,” but its policy states: “The FDA has considered the term 'natural' to mean that nothing artificial or synthetic (including all color additives regardless of source) has been included in, or has been added to, a food that would not normally be expected to be in that food.” It's important to know that the term 'natural' is not synonymous with "USDA Certified Organic," a regulated label with established criteria.

Our selection of natural energy bars contain real, whole foods providing carbohydrates, protein, and healthy fats to help keep you fueled between meals. When selecting our top choices, we considered overall nutritional content, ingredients and taste.

Here, the best natural energy bars.

What do buyers say? 86% of 6,100+ Amazon reviewers rated this product 4 stars or above.

RX bars take the best overall spot with a short, nutrient-packed ingredient list, including egg whites, almonds, cashews, and dates. Each bar contains 12 grams of protein (from egg whites and nuts), 7 grams of healthy fats (from almonds and cashews), and 5 grams of fiber to keep you feeling fuller longer. The natural flavors listed in the ingredients are not from artificial flavorings but rather from oils and extracts sourced from spices, fruits, and plants. These bars have a dense texture, so if you prefer a softer, less chewy bar, they might not be your best choice.

RX Bars come in various flavors to satisfy a range of taste buds, including Chocolate Sea Salt, Blueberry, Peanut Butter, Coconut Chocolate, and Mixed Berry. They also offer seasonal flavors, so you can skip the pumpkin spice latte filled with added sugars and fuel up on a Pumpkin Spice RX Bar.

The GoMacro protein bars offer wholesome, organic, vegan ingredients, including seeds, nuts, nut butters, puffed rice, dried fruits, pea protein, and brown rice protein. With 270 calories, 9 grams of fat, 3 grams of fiber, and 10 grams of protein, these bars can sustain you for longer periods of time between meals.

One thing to note on this bar is that organic brown rice syrup is first on the ingredient list. Brown rice syrup is a natural sweetener and binder made from breaking down the starches in cooked rice. While it is natural, it is still considered an added sugar and should be consumed in moderation.

Best Tasting: Larabar Gluten-Free Snack Bar Variety Pack 16 Pack

Lara Bar Pack


LARABARs contain just two to eight ingredients depending on the bar—all of which are whole, real foods. Ingredients include dates, almonds, fruit, cocoa powder, coconut, vanilla extract, and sea salt. All of the bars are sweetened with dates, which provide a natural source of sugars plus the added benefit of fiber. When natural sugars are digested with fiber, they are absorbed into your bloodstream more slowly, so they won’t cause the same spike (and subsequent drop) in blood sugar like processed, concentrated sweets would.

With flavors like Cashew Cookie, Chocolate Coconut, Chocolate Chip Cookie Dough, and Cherry Pie, make this bar your go-to for when you’re craving a sweet treat. The Chocolate Chip Cookie Dough flavor contains 210 calories, 11 grams of fat, 25 grams of carbohydrates, and 3 grams of protein.

Rx Bars (view at Amazon) provide protein, healthy fats, and fiber from whole real foods making them the perfect choice to fuel you on-the-go. They also come in a range of flavors and are widely available at grocery stores, gas stations, and airports, making them a safe bet for a nutrient-packed snack wherever you’re headed.
