Nutrition Bar Solutions:


BarFlex® is a partially hydrolyzed whey protein isolate (WPI) with a unique combination of whey proteins and peptides to minimize bar hardening and extend the shelf life of nutrition bars. BarFlex creates and maintains a long, chewy texture and is the ideal choice for 100% whey protein bars.


Bar Pro™ is a partially hydrolyzed milk protein isolate (MPI) formulated to extend the shelf-life of high-protein nutrition bars. BarPro is 90% protein, enhancing bar texture, and providing a clean flavor profile.


barGain™ is a cost-effective, unique combination of whey protein and soy protein that provides enhanced bar functionality and a complete protein solution for low to moderate protein bars.

Prolibra® is an all-natural, patent-pending ingredient for healthy weight loss.

Prolibra is clinically-proven to promote fat loss, retain lean muscle mass and lower glycemic index.
