Dietary purpose
Protein bars are targeted to people who primarily want a convenient source of protein that doesn't require preparation (unless homemade). There are different kinds of food bars to fill different purposes. Energy bars provide the majority of their food energy (calories) in carbohydrate form. Meal replacement bars are intended to replace the variety of nutrients in a meal. Protein bars are usually lower in carbs than energy bars, lower in vitamins and dietary minerals than meal replacement bars, and significantly higher in protein than either.
Protein bars are mainly used by athletes or exercise enthusiasts for muscle building.

Protein bar niche
In addition to other nutrients, the human body needs protein to build muscles. In the fitness and medical fields it is generally accepted that protein after exercise helps build the muscles used. Whey protein is one of the most popular protein sources used for athletic performance. Other protein sources include egg albumen protein and casein, which is typically known as the slow digestive component of milk protein. Vegan protein bars contain only plant proteins from sources like peas, brown rice, hemp, and soybeans.
Issues
Sugar Content
Protein bars may contain high levels of sugar and sometimes are called "candy bars" in disguise. Sugar from natural sources such as fruit are thought to be healthier after workouts than other sugars, and many health experts argue that sugar from fruit improves athletic performance.
In order to keep calories and carbohydrate content relatively low, many protein bars contain sugar alcohol as sweetener. In larger quantities, like many other incompletely digestible substances, sugar alcohols can cause bloating, diarrhea and flatulence.
In France special regulation is present for hyperprotéiné bars.
Supplementation Controversy
There is a disagreement over the amount of protein required for active individuals and athletic performance. Some research shows that protein supplementation is not necessary. Athletes generally consume higher levels of protein as compared to the general population for muscular hypertrophy and to reduce lean body mass lost during weight loss. The American Dietetic Association, Dietitians of Canada, and American College of Sports Medicine supports higher protein intake for athletes in order to enhance athletic performance and recovery.
