These bars are not specifically marketed as low-carb, and the chocolate coating and sweet flavors suggest they might contain more sugar than stricter low-carb options. They likely have moderate fiber but could be higher for improved carb control.

Calorie content appears reasonable for a snack but might be on the higher side compared to simpler protein bars. If you want a protein bar that tastes good and offers collagen benefits with a decent protein punch, these are a solid pick.

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.

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.
