ZBiotics® Sugar-to-Fiber is the world's first probiotic that is designed to turn sugar into fiber inside your gut. Using patented bioengineering, our probiotic converts a small amount of the sugar you eat every day into levan—a rare prebiotic fiber your gut loves but is nearly impossible to get from Western foods. It's the next evolution in gut health: a probiotic that empowers your body to turn what you already eat into something your body truly needs.
Unlike standard probiotics that may never reach your gut or fiber powders that can cause discomfort by delivering too much fiber all at once, Sugar-to-Fiber works from within. It's engineered to transform sugar into soluble fiber throughout the day, creating a steady source of nourishment for your microbiome. It's fiber that works harder, made from your food, not added to it.
Most of us don't get enough fiber. Modern diets make it hard to reach daily needs. This fiber gap leaves your microbiome undernourished, impacting digestion, immunity, and overall gut health.
As your microbiome thrives, you may notice overall improvements in gut health, including:
Both flavors work the same way and provide the same daily benefits—the only difference is taste and how you like to use it.
Take daily for at least 3 months for the best and most lasting results as your gut adapts to continuous fiber production.

The long-term potential impact of a healthier microbiome are vast and vary from person to person. They cascade throughout the body and can include improvements to digestion, immune function, gut integrity, energy levels, nutrient absorption, and even psychological benefits like increased motivation for exercise and healthier food choices.
Fiber may be the most underappreciated macronutrient in the modern American diet, which is why Sugar-to-Fiber was designed to turn dietary sugar (sucrose) into levan fiber.

"Increasing the amount of dietary fiber we each consume is important in many ways for gut health. This is difficult to do at every meal because the best sources of fiber are whole vegetables, fruits, grains and nuts and our busy lifestyles often push us towards more processed, sugary foods. A probiotic that turns sugar in our diet into fiber is transformative because it actually creates fiber directly inside our gut that can then be used by other beneficial bacteria and it reduces the amount of sugar we metabolize at the same time."

"Fiber consumption is clearly important for health, but not everyone can tolerate fiber-rich food or supplements that dramatically increase fiber to the gut. The slow and steady amount of fiber that a product like Sugar-to-Fiber provides is a perfect solution."

ZBiotics Sugar-to-Fiber (or “Sugar-to-Fiber” for short) is a drink mix containing a patented, genetically engineered probiotic (B. subtilis ZB423™) that converts a small amount of the sugar you eat every day into fiber.
Specifically, Sugar-to-Fiber produces an enzyme called levansucrase, which breaks down molecules of a sugar called sucrose (also known as table sugar) and uses the components as building blocks to create a fiber called levan (a prebiotic fiber that is rare in most diets).
Our product is not designed to reduce blood glucose levels, nor do we have any data to support such a claim.
Sugar-to-Fiber works by converting a small amount (approximately 10g per day or less) of table sugar (sucrose) into a fiber called levan. At a molecular level, this process breaks apart sucrose into 2 molecular components: glucose and fructose. It then uses the fructose to construct levan, and releases the glucose molecule into the gut in the process. For those without adequate insulin regulation, the body is likely to react the same to the freed glucose, and consequently we do not anticipate any meaningful reduction in blood sugar. There are myriad benefits of having prebiotic fibers, but we do not have any data indicating levan is a hypoglycemic agent.
Sugar-to-Fiber contains a genetically engineered probiotic, Bacillus subtilis ZB423™, that takes a sugar called sucrose (table sugar) and uses it to create a fiber called levan. It does this by producing an enzyme called levansucrase.
When you mix Sugar-to-Fiber into your drink, the probiotic bacteria are naturally dormant and in a protective state called an endospore. The bacteria in this endospore form can travel safely through your stomach and make it to the intestines, where they will “wake up” and start producing the enzyme levansucrase. This enzyme is capable of breaking down the sucrose you consume into its two individual molecular components: glucose and fructose. It then strings together the free fructose molecules into long chains to make molecules of levan fiber. Remember: at a molecular level, fibers are just long strings of simple sugars, but their different structures totally change how your body interacts with them. Levan is a rare and beneficial fiber that supports a healthy and diverse microbiome.
The primary benefits of Sugar-to-Fiber relate to microbiome health. Sugar-to-Fiber is unlikely to break down enough sugar to impact things like caloric intake, blood sugar, or weight.
But it will impact your gut health. Sugar-to-Fiber provides exactly what we know makes your microbiome healthier:
And the benefits of a healthier microbiome for your body are vast and vary from person to person: better immune function, improved gut-lining integrity, improved bowel function, increased short-chain fatty acid synthesis, better nutrient utilization, improved energy, psychological benefits such as greater desire to exercise and cravings for healthier foods, and more.*

Unflavored has a neutral taste and is designed to mix easily into a wide range of drinks and foods without changing their flavor.
Maple adds a light, subtle sweetness that pairs especially well with foods and drinks like coffee, oatmeal, and yogurt.
No, both Unflavored and Maple Sugar-to-Fiber work the same way and support gut health in the same way. Flavor does not affect performance or benefits.
Simply mix one stick pack into a beverage or food of your choice and enjoy.
While mixing it into a simple glass of water works great, we’ve found that incorporating it into things like coffee (hot or iced), breakfast cereal, yogurt, or a smoothie can be easier to incorporate into your morning routine and tastier if you’re not partial to the flavor in water alone. Sugar-to-Fiber works well mixed with a variety of things, so don’t hesitate to experiment.
It is important to note that Sugar-to-Fiber does not completely dissolve and will appear cloudy with some dark flecks in clear beverages. It also will settle out if left to sit for more than a few minutes. Give it a few stirs or shakes every once in a while if consuming the beverage slowly.
If you are having trouble mixing with liquid, one tip that works well is to pour Sugar-to-Fiber into your glass first, and then add your beverage.
The benefits of Sugar-to-Fiber are greatest when you consume it daily. While each Sugar-to-Fiber day helps you get closer to your daily fiber goals (by converting a larger gross amount of sugar to fiber), consistent use is more likely to result in meaningful, lasting improvements to your gut microbiome.
No – you should consume shortly after mixing. If you let it sit for a long time after mixing, it’s possible that either it gets contaminated by environmental microbes, or the probiotic germinates (“wakes up”) prematurely and loses its functionality when you eventually consume it. We recommend letting it sit for no longer than 2-3 hours, especially if you’re mixing it into something that can go bad earlier, like oatmeal or a smoothie.
We engineered Sugar-to-Fiber and created a probiotic strain with a completely novel and unique function that no other product on the market offers! Unlike typical probiotics that simply add bacteria or fiber supplements that only deliver pre-formed fiber, Sugar-to-Fiber is engineered to create fiber directly in the gut from the sugar you consume, offering targeted benefits you can't get from any other product on the market. Additionally, our probiotic is designed to produce a specific fiber called levan — a type of fiber that’s hard to get from a typical diet. By adding a rare fiber, Sugar-to-Fiber inherently helps increase fiber diversity, which is important for supporting a healthy, balanced gut microbiome.
Yes!
There should be no issue taking Sugar-to-Fiber in conjunction with other probiotics or supplements. Sugar-to-Fiber works in a unique way by converting some of the sugar you consume into a special fiber called levan, helping boost your overall fiber intake and complementing other fiber sources you may already take. Its targeted benefits make it different from typical daily probiotics, so it’s not redundant and you’re welcome to take both together!
If you have any concerns, or if you have a medical reason for consuming these other probiotics or supplements, it is always a good idea to consult your doctor before adding a new supplement or probiotic to your routine.
Yes!
We can confirm that Sugar-to-Fiber is free of all major allergens. Sugar-to-Fiber is tested, annually at minimum, against the allergens present in the manufacturing facility to ensure no cross-contamination. It does not contain:
