Quick answer
It is a lower-sugar swap for regular soda, not a proven gut product. A can typically holds 2 to 9 g of fiber, mostly inulin, and under 5 g of sugar, Cleveland Clinic says, against an FDA Daily Value of 28 g for fiber. No study we found has tested the sodas themselves, and inulin can cause gas and bloating. Dietitians say fiber from food comes first.
In brief
- Prebiotic sodas hold about 2 to 9 grams of fiber per can, depending on the brand. [Cleveland Clinic; Houston Methodist; UW Medicine]
- FDA's Daily Value for dietary fiber is 28 grams, and the Dietary Guidelines' adult fiber goals run from 22 to 34 grams a day, by age and sex. [FDA; Dietary Guidelines for Americans, 2020-2025]
- Most prebiotic sodas carry about 5 grams of sugar or less per 12-ounce can, against a Daily Value of 50 grams for added sugars. [UW Medicine; Mayo Clinic Press; FDA]
- The fiber is usually inulin, from chicory root, agave or sunchokes, and inulin can lead to gas and bloating in a lot of people. [Houston Methodist; UW Medicine]
- The sodas themselves have not been put to the test: a UW Medicine dietitian says there has been no real research on them, and a Houston Methodist gastroenterologist says the evidence is not enough to judge their claims. [UW Medicine; Houston Methodist]

What is prebiotic soda?
A fizzy soft drink with prebiotic fiber added. Cleveland Clinic's dietitian explains: "Prebiotic soda is a beverage that contains dietary fibers called prebiotics." The fiber is usually inulin, which "typically comes from agave or chicory root." Houston Methodist adds sunchokes, also sold as Jerusalem artichoke, and guar gum as sources.12
You will not notice the fiber. Cleveland Clinic explains: "As a soluble fiber, inulin dissolves in water, so you don't feel or taste it in the soda." UW Medicine notes that inulin "adds a slightly sweet flavor to the drinks without having to use sugar".13 The rest of the can is a flavored drink: Cleveland Clinic lists stevia, apple cider vinegar, fruit juice and natural flavors among the usual extras.1
What makes a fiber a prebiotic in the first place, in ISAPP's words, is set out in prebiotic vs probiotic.
How much fiber is in a can, compared with what you need?
About 2 to 9 grams per can, depending on the brand, according to Cleveland Clinic, Houston Methodist and UW Medicine. Set against FDA's Daily Value of 28 grams of fiber, the figure behind the %DV on a can's label, that is about 7 to 32 percent of a day's fiber, so one can covers part of a day, not most of it.1236
The Dietary Guidelines for Americans work out fiber at 14 grams per 1,000 calories, which puts adult goals between 22 and 34 grams a day, with the figure for each age and sex in their Appendix 1.8 FDA's rule of thumb for any label: 5 percent of the Daily Value or less per serving is low, and 20 percent or more is high.6
Our arithmetic, from the sources' numbers. 2 g is 7 percent of 28 g; 9 g is 32 percent. Against the Dietary Guidelines' adult goals, 2 g is 6 to 9 percent of a day and 9 g is 26 to 41 percent. The fiber on the can's own label is the number that counts.
One prebiotic in a can is also one kind of fiber. UW Medicine writes that "getting just one kind of fiber, isolated from the whole food it came from, won't necessarily give you the same benefits as the many kinds of fiber and other prebiotics and nutrients you ingest when eating whole grains, fruits and vegetables."3 Food grams of inulin and oligofructose, from chicory root to banana, are in our prebiotic foods list.
How much sugar is in prebiotic soda?
Usually about 5 grams or less per can, far below regular soda. Mayo Clinic Press says many prebiotic sodas "contain five grams of sugar or less and total 50 or fewer calories per 12-oz can", while UW Medicine notes that regular soda "can contain as much as 40 grams of sugar". FDA's Daily Value for added sugars is 50 grams a day.537
Cleveland Clinic puts the typical sugar at less than 5 grams per can and says most cans "contain stevia to add sweetness without calories."1 Fruit juice counts too: FDA's definition of added sugars includes "sugars from concentrated fruit or vegetable juices."7 And the grams add up across a day. Houston Methodist puts it plainly: "Like regular soda, prebiotic soda contains added sugar and calories, which can add up if you're having several in a day."2
Does prebiotic soda cause gas or bloating?
It can, because gut bacteria break inulin down. UW Medicine says inulin "can lead to gas and bloating in a lot of people" and "can also draw water into the bowel, causing you to experience loose stools". Cleveland Clinic says prebiotic soda can trigger bloating and gas, especially if you are not used to eating much fiber.31
Cleveland Clinic's dietitian notes that some people eat only about 10 grams of fiber a day, and spells out what a can does to that:
"If you double that amount with a prebiotic drink, you're probably going to feel it."
Julia Zumpano, RD, LD, Cleveland Clinic, Dec 27, 2024
Cleveland Clinic's advice is to go slow: "If you want to try prebiotic soda, start with half a can so your body can adjust."1 Physician's Choice uses the same fibers in some of its own products and says so in its own words: "Our 60 Billion Probiotic and Digestive Enzymes contain inulin, and our Fiber Gummies contain chicory root fiber; gut bacteria break down fibers like these, which can cause gas."
How much gas and bloating trials recorded at each daily dose of inulin and other prebiotic fibers is in can prebiotics cause bloating?
Does prebiotic soda help your gut? What the evidence shows
No study we found has tested prebiotic sodas themselves, and the doctors and dietitians quoted here say as much. A Houston Methodist gastroenterologist says there is not enough evidence to evaluate the makers' claims; a UW Medicine dietitian says there has not really been any research on the sodas; a Hartford HealthCare dietitian calls for more studies.234
"We currently don't have enough evidence about these prebiotic sodas to evaluate the claims made by the manufacturers."
Dr. Eamonn Quigley, gastroenterologist, Houston Methodist, Mar 5, 2025
He spells out what that evidence would take: "legitimate studies evaluating the prebiotics used in the product, and whether the prebiotics exist in enough quantities to be impactful to the microbiome, and the outcomes".2 Hartford HealthCare's registered dietitian Emily Lewis: "there is little to no evidence to support the many health claims associated with these drinks. More studies are definitely needed."4
Where the sources agree is the comparison with ordinary soda. UW Medicine's gastroenterologist Christopher Damman: "They're not health foods, they're healthier foods."3 Whether a can's inulin is enough to matter is a dose question; one ISAPP scientist's arithmetic on a 2 g can is in do I need a prebiotic with my probiotic?
What should you read on a prebiotic soda can?
Five lines tell you most of what a can holds: the Dietary Fiber grams, which fiber it is, the Added Sugars grams, the sweetener, and any extras such as apple cider vinegar or herbs. Each one ties to a point the sources make about these drinks, set out below with its source.
Lines on a prebiotic soda can, and why each matters
| Line on the can | Why it matters | Source |
|---|---|---|
| Dietary Fiber, grams and %DV | Cans run from about 2 to 9 g. The %DV is figured on 28 g; 20 percent or more is high, 5 percent or less is low. | Cleveland Clinic1; FDA6 |
| The fiber's name: inulin, chicory root, agave inulin, Jerusalem artichoke, guar gum | Inulin is the most common soda fiber, and inulin "can lead to gas and bloating in a lot of people". Start with half a can if you are new to it. | UW Medicine3; Cleveland Clinic1 |
| Includes Added Sugars | Most prebiotic sodas list 5 g or less; regular soda can reach 40 g. The Daily Value for added sugars is 50 g. | Mayo Clinic Press5; UW Medicine3; FDA7 |
| Sweetener: stevia, fruit juice or juice concentrate | Most cans use stevia for sweetness without calories. Sugars from concentrated fruit juice count as added sugars on the label. | Cleveland Clinic1; FDA7 |
| Apple cider vinegar or herbs | It is unknown whether a can holds enough vinegar to be beneficial; vinegar can cause reflux and heartburn for some people, and some herbs can interfere with certain medications, including blood thinners. | Cleveland Clinic1; UW Medicine3 |

The same habit works on any fiber product: read the grams of fiber and its type first, then the sugars. A prebiotic named on its own line, with its own amount, is easier to judge than one folded into a blend; how that reads on a supplement panel is in our guide to prebiotic supplements.
Where Physician's Choice fits
Physician's Choice, which publishes this site, makes Prebiotic Probiotic, a capsule whose label lists inulin from chicory at 250 mg; it is a supplement, not a drink, and nothing on this page compares it with a can.10
See the label on physicianschoice.comTalk to a professional if
- You take a medicine regularly and the can lists herbs; UW Medicine says some herbs can interfere with certain medications, including blood thinners3
- You have a digestive condition; Cleveland Clinic says inulin may cause intestinal distress in people with chronic digestive conditions1
- Gas symptoms bother you or change suddenly, or come with belly pain, constipation or diarrhea, the points at which NIDDK says to talk with your doctor9
If you are pregnant or breastfeeding, are seriously ill, or have a weakened immune system, consult your healthcare provider before taking a probiotic or any other dietary supplement.
The three items follow UW Medicine, Cleveland Clinic and NIDDK; the last line is Physician's Choice wording.
The answer, again
Prebiotic soda is a lower-sugar alternative to regular soda that adds about 2 to 9 grams of fiber a can, mostly inulin, which can cause gas. No study we found has tested the sodas themselves, so read the fiber and sugar lines on the can and, as the dietitians quoted here advise, get most of your fiber from food.

Quick questions
Is prebiotic soda good for you?
It is a lower-sugar swap for regular soda, not a proven gut product. Cans typically hold 2 to 9 g of fiber, mostly inulin, and under 5 g of sugar, but no study we found has tested the sodas themselves, and the inulin can cause gas. Dietitians at Cleveland Clinic and UW Medicine say food comes first.
What is prebiotic soda?
A fizzy drink with added prebiotic fiber, which Cleveland Clinic says is usually inulin from agave or chicory root. Houston Methodist adds sunchokes (Jerusalem artichoke) and guar gum as sources. Inulin dissolves, so you do not taste it. Most cans are sweetened with stevia, and some add fruit juice.
How much fiber is in a prebiotic soda?
About 2 to 9 grams per can, depending on the brand, according to Cleveland Clinic, Houston Methodist and UW Medicine. FDA's Daily Value for fiber is 28 grams, so by our arithmetic one can covers 7 to 32 percent of it. Read the Dietary Fiber line on the can itself.
Does prebiotic soda make you gassy?
It can. UW Medicine says inulin can lead to gas and bloating in a lot of people, and Cleveland Clinic says a prebiotic drink can trigger these symptoms, especially if you are not used to much fiber. Cleveland Clinic suggests starting with half a can so your body can adjust.
Is it OK to drink prebiotic soda every day?
No source on this page sets a daily limit. Houston Methodist notes that prebiotic soda still has added sugar and calories, which add up if you have several a day, and fiber added fast can bring gas. Count each can's sugar and fiber against the rest of your day.
