A new probiotic to help your gut

Genetically engineered by a team of PhD microbiologists, ZBiotics® Sugar-to-Fiber is a probiotic drink mix that turns sugar to fiber in your gut.

The primary benefits

More soluble fiber

Sugar-to-Fiber can deliver up to 10g of fiber per day from sugar you eat.

More fiber diversity

Sugar-to-Fiber produces levan fiber, which, due to its rarity, improves fiber diversity—critical to microbiome health.

Gradual delivery of fiber

Sugar-to-Fiber delivers small amounts of fiber throughout the day, making it gentler on your gut and better for your microbiome than a single large dose.

Diversion of intestinal sugar

Sugar-to-Fiber breaks down sucrose to glucose and fructose, then uses the fructose to build fiber, diverting it from downstream fatty acid synthesis.

"The world needs more companies that are dedicated to building new products with biotechnology."

Zack Abbott, PHD Microbiology & Immunology
University of Michigan

I started ZBiotics because I strongly believe we can use modern biotechnology to make incredible products that have real and unprecedented benefits for people, products that couldn't exist before this technology was available. The world needs more companies that are dedicated to building new products with biotechnology in a way that aligns with people's values and are safe, responsible, and transparent.

"At ZBiotics, we're not limiting ourselves to passive wellness products—we're engineering microbes that actively help people in their daily lives."

Bentley Shuster, PHD Microbiology
New York University

At ZBiotics, we’re not limiting ourselves to passive wellness products—we’re engineering microbes that actively help people in their daily lives. We’re showing that genetic engineering can be used transparently and responsibly to solve real-world problems. I see a future where GMOs reshape how we think about health, sustainability, and wellness—and I’m proud to be part of a team that’s turning that vision into a reality.

"I've spent my career developing and engineering microbes to create better, more sustainable ingredients and materials."

Kim Wemmer, PHD Biochemistry
UC San Francisco

I've spent my career developing and engineering microbes to create better, more sustainable ingredients and materials. At ZBiotics, I’m proud to use that technology to build products that truly improve people’s day to day lives. I’m also really excited to share our work openly and thoughtfully—so others can feel just as enthusiastic about our products as we do.
