Protein Bars

Protein is a key nutrient in the growth and maintenance of lean muscle mass. During exercise muscle fibres are broken down, providing high-quality protein post-exercise can stimulate muscle repair and rebuild. Our award-winning protein bars are ideal as a post-workout option or a high-quality protein snack to hit your daily protein goals.
