Our Story

Caltein Co. was founded by hobbyist bodybuilder and hiking enthusiast Aaron Sager while preparing for a weekend getaway to Yosemite National Park. Excited for the views but not the protein snacks he packed in his bag, he wondered:

Would using real ingredients make protein snacks taste better?

Aaron returned from his trip and immediately began testing recipe ideas, making a routine of gathering feedback from roommates, friends, and even his local gym community. When others started asking to buy his free samples, he then knew the days of settling on protein snacks would soon be behind them.

Demand began to skyrocket and what started in a small apartment kitchen quickly grew into a full-scale operation. Today, Aaron still oversees every batch, ensuring that each protein snack delivers on quality, taste, and nutrition—because you should enjoy your protein!
