At ZBiotics, we make genetically engineered probiotics that improve daily life. As a group of motivated, yet down-to-earth people, we are fueled by two things: a love for science and a commitment to being people-first. GMO products like ours – built to create benefits for people in their daily lives – are the future. As the first to market, we believe it’s our duty to set a high bar for product quality, safety, and transparency for others to follow.

In 2019, ZBiotics launched Pre-Alcohol™ – the world's first genetically engineered probiotic drink – designed to break down acetaldehyde, an unwanted alcohol byproduct. In 2024, we launched Sugar-to-Fiber™ – a genetically engineered probiotic drink mix – that creates fiber from the sugar you already eat, contributing to microbiome health.

With a full line of genetically engineered probiotics in development, our team is growing. We’re looking for people as excited as we are to build this new category of consumer products. ZBiotics is headquartered in San Francisco and backed by venture investors including Y Combinator and Khosla Ventures, among others.
