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 – designed to break down the alcohol byproduct that leads to rough mornings after drinking. In 2024, we launched a genetically engineered probiotic drink mix, Sugar-to-Fiber, that creates fiber from the food you eat. This one-of-a-kind product helps to improve the diversity of gut bacteria and overall gut 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.
