What 1,058 coded consumer comments and 14 quarters of retail review data reveal about the GLP-1 shopper already in the fiber aisle.

‍

‍

The fibermaxxing trend is everywhere at once: a 7.4 million-play TikTok, a 10,400-upvote Reddit thread, national press from CNBC to Women's Health. The decisive evidence sits at the point of purchase, in retail reviews on legacy fiber powders that now read "If you are on a GLP-1, these are a must have."

‍

This report connects that conversation to the shelf across 400+ fiber UPCs in supplements, food, and beverage. It maps the two jobs driving purchase, the dosing question shoppers are actually asking, and the whitespace still open: the GLP-1 shopper is already in the fiber aisle, and no brand owns them yet.

• A data-rich download connecting social conversation, retail reviews, and shelf data across the fiber category.
• Includes the two jobs driving purchase, the dosing gap, and the competitive landscape from legacy powders to TikTok-native challengers.
• Built for CPG and retail teams who want to move while the whitespace is open.

‍

Highlights:

• Real review language: explicit GLP-1 mentions in fiber reviews grew from zero to nine per quarter, with review volume up 4-8x since 2023 and ratings stable.
• The two jobs-to-be-done: GI comfort that converts to repeat purchase, and the "nature's Ozempic" narrative that earns attention but carries claim risk.
• The most defensible unclaimed position in the category: gentle, correctly dosed fiber for the GLP-1 gut, and who is moving first, from legacy powders to TikTok-native newcomers.
