RXBAR Protein Bar

RXBAR was founded in 2013 by Peter Rahal and Jared Smith in Chicago, Illinois. The brand gained rapid popularity by focusing on 'clean label' transparency, famously listing its core ingredients—such as egg whites, almonds, cashews, and dates—in large, bold text directly on the front of the packaging. This minimalist approach was a direct response to the overly processed protein bars common in the fitness industry.

In 2017, the brand reached a major milestone when it was acquired by the Kellogg Company for $600 million. This acquisition allowed RXBAR to scale its distribution globally while maintaining its signature recipe and branding. Following the 2023 corporate restructuring of Kellogg Company into separate entities, RXBAR became part of Kellanova, the global snacking powerhouse.

Today, RXBAR remains a leader in the protein bar category, known for its chewy texture and simple ingredient profile. While the brand originated as a kitchen start-up in the United States, its manufacturing processes have expanded to meet international demand, though operations remain heavily centered in North America under the stewardship of Kellanova's global snack division.
