10 Best Low Carb Protein Bars 2025 in the United States

The Quest Nutrition Pumpkin Pie Protein Bar is a solid option if you’re looking for a low-carb, high-protein snack. Each bar delivers 20 grams of protein, which is great for supporting muscle repair or keeping you full between meals. With only 4 grams of net carbs and just 1 gram of sugar, it fits well within a low-carb diet. It’s also gluten-free and kosher, making it suitable for various dietary needs. The bar uses dairy-based protein, offering essential amino acids, which is beneficial if you don’t have dairy restrictions. The pumpkin pie flavor adds a seasonal twist that many find enjoyable, and the texture is typically chewy but not too dense, making it easy to eat on the go.

As a seasonal product, it may not be available year-round. While the sugar content is low, the bar contains some sweeteners and processed ingredients typical in protein bars, which might not appeal to those seeking a completely natural snack. Calorie-wise, it provides a moderate amount suitable for snacking without overdoing it. This bar is ideal for people who want a tasty protein boost with minimal carbs and sugar, especially if they appreciate seasonal flavors and need something convenient for busy days.

IQBAR Brain and Body Plant Protein Bars are designed to be a convenient, low-carb snack that supports a healthy lifestyle, especially for those following keto or vegan diets. Each bar offers 12 grams of plant-based protein, which is a solid amount to help keep you full and energized. They are very low in sugar, with only 1 gram per bar, and have just 2-3 grams of net carbs, making them a good choice if you’re aiming to limit carbohydrate intake. High fiber content (7-9 grams) helps with digestion and also contributes to feeling full longer.

The bars are gluten-free, dairy-free, soy-free, and vegan, which makes them suitable for many dietary restrictions. Ingredients include brain-boosting nutrients like Lion’s Mane mushroom, Magnesium, Vitamin E, and MCTs, which are a nice touch for supporting mental focus and energy. Calorie-wise, each bar contains between 160 and 180 calories, which keeps it light enough for a snack or meal replacement without being too heavy.

In terms of taste and texture, the bars come in a Chocolate Lovers variety with flavors like Chocolate Sea Salt, Peanut Butter Chip, and Almond Butter Chip. Reviews often mention they have a pleasant taste and a chewy texture, which many find enjoyable. For those who prefer very soft or crunchy bars, this might not perfectly match their preference. While the bar is low in net carbs, the total carbs range from 9 to 12 grams due to fiber, which is fine for most but worth noting for those extremely strict on carbs. The price point might be a bit higher than some basic protein bars, reflecting the clean ingredients and added brain nutrients. IQBARs represent a strong choice for anyone looking for a tasty, nutrient-rich low-carb protein bar that fits vegan and keto diets, especially if you value added brain-supporting ingredients and fiber.

These bars are gluten-free and use high-quality dairy proteins that supply essential amino acids needed by the body. With around 200 calories per bar, they offer a balanced snack without excessive calories. Some people might find the bars a bit dense or sweet, and the ingredient list includes artificial sweeteners and additives common in protein bars, which may not appeal to those preferring very natural ingredients.

This variety pack is ideal for busy individuals seeking a reliable, tasty, low-carb protein snack on the go, especially for those following keto or gluten-free diets.
