Protein bars

What are Protein Bars?

Proteins are versatile macromolecules that are present in all living systems and perform vital functions in practically all biological processes: they function as catalysts, play a role in the transport and storage of other molecules such as oxygen, provide mechanical support and immune protection, generate movement, transmit nerve impulses, and control cell growth and differentiation. They are also a key source of amino acids.

Protein bars essentially provide a quality source of protein, a few carbohydrates and fats. To be considered a high protein bar, 20% of its energy value must come from protein.

Certain protein bars come with additional nutrients, such as vitamins, minerals, caffeine, glutamine, taurine or chromium. These bars are usually designed with specific goals, for instance, as meal replacements.

Main advantages of protein bars:

  • Quick and convenient snacks
  • Source of dietary protein
  • Contribute to meet the body's protein needs
