Protein bars are popular because they are easy to take on the go, and they are often marketed as a healthy product with a “high protein content.”
But a high number on the package does not always mean that the body can use the protein optimally, explains Jackson Health System.
Large differences in quality
A recent study published in Scientific Reports examined more than 1,600 protein bars. The results showed that most bars contained enough protein, but that the quality was often low.
Bars containing dairy proteins such as whey were among the best.

By contrast, ingredients such as collagen, fiber, and sweeteners could make it harder for the body to absorb the protein.
The point comes further down
Protein is important for the body. Among other things, it helps support muscles, bones, and the immune system.
This is especially important for children, older adults, athletes, and people recovering from illness or injury.
However, experts emphasize that regular food should still be the first choice.

Foods such as eggs, fish, lean meat, yogurt, tofu, beans, and quinoa provide protein in a more natural form.
Protein bars can be a practical supplement when time is limited, but they should not replace proper meals.
If choosing a bar, it is recommended to look for at least 10 grams of protein, a low sugar content, at least 3 grams of fiber, and ingredients such as nuts, seeds, and oats.
