Do TUSHY Reboot Fiber Gummies work? Four grams of inulin, trials that used twelve, and a 3.4 on Amazon

Quick answer

Do TUSHY Reboot Fiber Gummies work? No trial of the gummy exists. Two gummies list 4 g of chicory inulin, while the constipation trials of chicory inulin used 12 g a day and a review of 16 fiber trials found benefit above 10 g a day. The brand’s GLP-1 and weight claims carry no citation, and inulin at 5 g or more caused mild gas in healthy adults. Amazon shows 3.4 from 49 ratings; the brand’s own page shows 4.19 from 27, seven of them incentivized.

The TUSHY label gives 4 g of inulin per two gummies. A gas tolerance trial used 8 g a day and found no significant gap from placebo, two constipation trials used 12 g a day and raised stool frequency, a review of 16 fiber trials found benefit above 10 g a day, and a weight trial used 21 g a day of oligofructose and left active GLP-1 unchanged.

TUSHY Reboot Fiber Gummies are mixed berry gummies from a bidet company, and the Supplement Facts panel lists one active: 4 g of inulin from chicory root per two gummies, taken once a day. That is a third of the 12 g a day used in the constipation trials of chicory inulin. This page sets out the label, the inulin trials by dose, the brand’s GLP-1 and weight claims, the reviews on each platform and the price by route.

What TUSHY Reboot is, and what it is not

The serving is two gummies, with 30 servings in the 60-count pouch. The panel prints 25 calories, 6 g of total carbohydrate, 4 g of dietary fiber (14% of the daily value) and 10 mg of sodium. One line, headed Prebiotic Fiber Blend, gives 4 g, and the only ingredient under it is “Inulin (Fructooligosaccharides [FOS])” from chicory root. The blend has a single named ingredient, so there is no hidden split, but the label does not say how much of the 4 g is short-chain FOS and how much longer-chain inulin.

The other ingredients are pectin, agar agar, tapioca starch, sodium copper chlorophyllin, black carrot juice concentrate (color), citric acid, sodium citrate, natural strawberry and mixed berry flavors, and a palm glaze of palm oil and carnauba wax. No sweetener is listed, and the pouch carries “Sugar Free” and “Vegan Friendly” badges. There are no bacteria in it: it is a prebiotic, not a probiotic. The pouch reads “Distributed by TUSHY Inc.” of Brooklyn, a company that sells bidets and other bathroom goods; this is its one gummy, and the maker of the gummy is not named.

The brand’s page claims, with no citation, support for occasional bloating, a balanced gut and regularity; “20% MORE Fiber per gummy vs. leading competition”; as much fiber as a stalk of broccoli (4 g against 3.9 g in its own image); and the GLP-1 and weight claims taken up below.

The trial of the product itself

There is none. PubMed returned no records for the gummy, ClinicalTrials.gov lists no study under TUSHY, and no laboratory, certificate or facility is named on the page, the pouch image or the Amazon listing. Everything below is evidence for chicory inulin as a class.

The evidence for inulin, against the label dose

Two crossover trials tested chicory inulin in constipation, and both used 12 g a day. In 44 adults with constipation taking 4 g three times a day for four weeks, stool frequency was 4.0 a week against 3.0 on placebo (P = 0.038) and stools were softer (Micka et al., 2017). In 39 adults with functional constipation, 12 g a day for four weeks produced larger changes in stool frequency and abdominal symptoms than placebo (Puhlmann et al., 2025). Reaching 12 g from this gummy would take six gummies, about $3.90 a day at $1.30 a serving, against a label direction of two.

A 2022 meta-analysis of 16 randomized trials in 1,251 adults with chronic constipation found a response in 66% on fiber against 41% on control, but only at doses above 10 g a day; flatulence was higher on fiber as well (van der Schoot et al., American Journal of Clinical Nutrition, 2022). A separate meta-analysis of 47 publications found that short-chain beta-fructans, the class that includes FOS, added 0.36 bowel movements a day, while long-chain fructans showed no effect (de Vries et al., 2019). The panel names the ingredient as both inulin and FOS, so it cannot show which finding applies.

The one trial nearer the label dose tested gas tolerance. In 36 people with abdominal symptoms, 8 g of chicory inulin a day for four weeks cut gas retention by 22% from baseline, but the gap from placebo was not significant (P = 0.343) and symptoms were unchanged in both groups (Azpiroz et al., 2017).

Taken together: chicory inulin raised stool frequency at 12 g a day, the fiber review found benefit above 10 g, and this label gives 4 g. No trial tested 4 g a day for constipation.

The GLP-1 and weight claims

The pouch and page say “GLP-1 friendly” and that inulin is “4x more effective at weight management than other fiber”, with no citation. The human trials of oligofructose and satiety hormones used much higher doses. In 48 overweight adults, 21 g a day for 12 weeks lowered body weight (about 1 kg, against a gain of 0.45 kg on placebo) and ghrelin and raised PYY, but did not change active GLP-1 (Parnell and Reimer, 2009). In 31 healthy adults, 16 g a day for 13 days raised the GLP-1 area under the curve against 10 g, 45 against 41 pmol/l x h (Verhoef et al., 2011). We found no trial at 4 g a day.

How to take TUSHY Reboot

The page says adults take two gummies daily and chew them thoroughly before swallowing; the pouch adds “or as directed by your healthcare professional”. Food is not mentioned. The constipation trials ran four weeks, so a fair test is several weeks.

Side effects and who should not take it

Gas is the recorded effect of inulin. In 26 healthy adults, single doses of 5 g and 10 g of inulin or oligofructose raised mild gas symptoms, flatulence first and then bloating (Bonnema et al., 2010). At 4 g a serving this gummy sits just under the 5 g where those symptoms began, and one reviewer on the brand’s page wrote that their gas increased.

The pouch says to consult a doctor before use if you are pregnant, nursing, taking any medications or have a medical condition, and to keep it out of reach of children.

Allergen statement. The product page and the Amazon listing both say “Contains tree nuts (coconut)”. The printed ingredient list shows no coconut ingredient; the glaze is palm oil and carnauba wax. The statement and the list do not match, and the pouch images we read show no allergen line, so anyone avoiding tree nuts or coconut would need to check the pouch or ask the brand.

What the reviews say

Amazon shows 3.4 from 49 ratings, on a listing sold by TUSHY and shipped by Amazon: 43% five-star, 11% four, 20% three, 3% two and 23% one-star. The brand’s own page runs a review app showing 4.19 from 27 reviews. Seven of those 27 are flagged “incentivized” by the app (six five-star and one four-star), and one says the gummies arrived as a sample gift. The other 20 average 3.95. Trustpilot shows 3.4 from 93 reviews, 43% five-star and 39% one-star, but it is a profile for the whole company and none of its reviews mentions the gummies. We could not read the Amazon review text.

The recurring praise on the brand’s page is regularity within days to a week, a candy-like taste and no powder to mix. The recurring complaint is no effect: four of the 27 cards are one-star, and Amazon’s 23% one-star share points the same way. One reviewer reports more gas, and another says a subscription could not be cancelled.

Common questions

Do TUSHY Reboot Fiber Gummies work for constipation?

No trial of the gummy was found. Chicory inulin raised stool frequency in 12 g a day trials, and a review of 16 fiber trials found benefit only above 10 g a day, while two gummies give 4 g. On Amazon it holds 3.4 from 49 ratings, with 43% five-star and 23% one-star.

What is in TUSHY Reboot Fiber Gummies, and how many do you take?

Two gummies list 4 g of inulin (fructooligosaccharides) from chicory root, 25 calories, 6 g of carbohydrate, 4 g of fiber and 10 mg of sodium. The other ingredients are pectin, agar agar, tapioca starch, color, citric acid, sodium citrate, natural flavors and a palm glaze. Adults take two gummies daily and chew them thoroughly; a pouch holds 30 servings.

Do TUSHY Reboot gummies work for GLP-1 or weight?

The brand says inulin can naturally stimulate GLP-1 and is “4x more effective at weight management than other fiber”, and cites no study. A 12 week trial of oligofructose at 21 g a day in 48 overweight adults lowered weight and ghrelin but did not change active GLP-1. No trial at 4 g a day was found.

Are TUSHY Reboot Fiber Gummies safe, and do they contain coconut or tree nuts?

The pouch says to consult a doctor if pregnant, nursing, taking any medication or with a medical condition. Inulin at 5 g or more caused mild gas in healthy adults in a tolerance study. The product page and Amazon say “Contains tree nuts (coconut)”, which the printed ingredient list does not show, so the pouch or the brand is the place to check.

Why does Amazon show 3.4 when the brand’s page shows 4.19?

They are different review pools. Amazon’s 3.4 is from 49 ratings on an independent listing, and the brand’s 4.19 is from 27 reviews in an app on its own page, seven of them flagged incentivized. The other 20 average 3.95.

How much do TUSHY Reboot Fiber Gummies cost, and can they be returned?

A 30 day pouch is $39.00 on the brand site and on Amazon, about $1.30 a day. The brand’s subscription brings that to $1.17, or $1.04 on the 90 day pack, and Amazon Subscribe & Save to $1.04. The refund policy lists the gummies as not eligible for returns, the product is tagged final sale, and Amazon marks it non-returnable.

TUSHY Reboot vs Vitamatic or other fiber gummies: what is different?

TUSHY gives 4 g of chicory inulin per two gummies, and the Vitamatic gummy prints 7 g of fiber per three. No trial compares them, and the doses that helped constipation in trials were 12 g of inulin a day or more than 10 g of fiber a day.
