Does Promix Debloat work? The three Bacillus species, the trial the brand describes and what the reviews say

PROMIX Debloat is a once-a-day powder in single-serve sticks from Promix Nutrition of Gainesville, Florida: three Bacillus species, baobab fruit powder and vitamin C, stirred into water in the morning. What sets it apart from the capsules on the next shelf is the claim that the finished formula went through a placebo-controlled trial. This page sets out what the label prints, what that trial has disclosed, what the nearest published trials show, and what the reviews and refund terms say.

What Debloat is, and what it is not

The Supplement Facts panel is short. Each stick carries 5 billion CFU of Bacillus coagulans, Bacillus subtilis and Bacillus clausii, as one combined figure “at the time of manufacture”, so the count at the end of shelf life is not stated. It also carries 2,000 to 2,600 mg of wild organic African baobab (2,600 mg in Florida Orange, 2,500 in Fresh Watermelon, 2,000 in Unflavored), which the panel counts as 1 g of dietary fiber, and vitamin C at 100% of the Daily Value with the amount not printed. The flavored sticks are sweetened with monk fruit; there are no enzymes.

No strain designation is printed for any of the three species, and there is no count per species, so the share of the 5 billion that is B. coagulans is not known. The brand says so itself: its article states that strain designations are not published on the product page, only the species, and that readers can ask the company for them. All three organisms are spore-formers, which is why the sticks are shelf stable, and the brand calls baobab the prebiotic.

The trial the brand describes

The brand says Debloat “was studied as the finished formula, in a triple-blind, placebo-controlled, IRB-approved trial” lasting 12 weeks, with results at week 8 and week 12. It publishes participant agreement statements: 83% agreed the severity of their bloating had decreased, 81% agreed the product improved their digestive comfort, and 81% said they had experienced less bloating.

Placebo response is why the missing arm matters. In the GBI-30 trial below, the authors wrote that a strong placebo effect was evident.

The evidence for the ingredients

The nearest trials are of single, named B. coagulans strains in other products:

• MTCC 5856: 70 adults with functional gas and bloating took 2 billion spores a day or placebo for four weeks; 66 completed. The GSRS indigestion score fell from 8.91 to 3.06 on the probiotic against 9.42 to 8.43 on placebo (P<0.001 for the difference). The authors are from the strain’s maker (Majeed et al., 2023).
• GBI-30, 6086: 61 adults with gas after meals, four weeks, in a Digestive Advantage product. The probiotic beat placebo on GSRS abdominal pain (P=0.046) and total score (P=0.048); distension was a trend (P=0.061) (Kalman et al., 2009).

Debloat prints no strain code, so these results are not shown to apply to it, and its 5 billion CFU is shared across three species against 2 billion spores of one strain in the MTCC 5856 trial. For B. subtilis and B. clausii in adults with bloating we found no randomized trial (our search was not exhaustive).

For baobab we found no completed human trial on gut bacteria or bowel outcomes. An industry-funded laboratory study found the powder raised short-chain fatty acids with human fecal bacteria (Foltz et al., 2021), and a 45-day trial in 50 adults with obesity has a published protocol only (Riedel et al., 2025). At 1 g of fiber a stick, the label dose is small.

What guidelines say about probiotics and bloating

The American Gastroenterological Association’s 2023 practice update on belching, bloating and distention advises against using probiotics to treat abdominal bloating and distention; it is an expert review, not a graded guideline (Moshiree et al., 2023). An umbrella review of 27 systematic reviews of probiotics in IBS found small or inconsistent effects on bloating, with mostly low or very low certainty (Ballena-Caicedo et al., 2026). The brand quotes the AGA statement and says to judge the specific formula: is the strain named, is the dose stated per serving, was the finished formula tested?

How to take Debloat

The flavored panels say to mix one packet into 12 to 20 oz of water and drink it in the morning on an empty stomach. The Unflavored panel says to mix one packet with 12 to 16 oz of water and that it may be combined with food. The brand’s trial read out at 8 and 12 weeks; both named-strain trials above lasted four weeks, and reviewers who report a change usually put it at a week or two. A month at the label dose covers those timelines.

Side effects and who should not take it

The panels carry only the FDA disclaimer. We found no pregnancy, breastfeeding, medication or age warning on the panels or the product page, and the panel lists no allergens. The brand’s article tells people with persistent or worsening bloating, weight loss, bleeding, vomiting, swallowing difficulty, fever or a change in bowel habit to see a clinician. Reviewers report a salty or unpleasant aftertaste in some flavors; one Trustpilot reviewer wrote that bloating got worse, and one brand-site reviewer wrote that it almost sent them to hospital, with no detail.

What the reviews say

The brand’s own site shows 4.93 from 1,762 reviews in a widget it hosts, pooled across flavors and sizes: 1,655 five-star, 102 four-star, none at three stars, 1 at two and 4 at one. Amazon shows 4.6 from 328 ratings (81% five-star, 9% four, 6% three, 1% two, 3% one), with the review text behind a sign-in. TikTok Shop shows 4.7 from 814 reviews. Trustpilot shows 1.7 from 50 reviews for the whole brand, not Debloat alone: 10% five-star and 76% one-star, on a profile the company has not claimed.

Recurring praise: a light flavor, less bloating within days to a couple of weeks, and the convenient sticks. Recurring complaints: no change in bloating, an aftertaste in some flavors, and, on Trustpilot, subscription and refund handling.

The subscription and refund terms

The brand’s published refund policy gives a 90-day guarantee on one-time orders, with a full refund to the original payment method. It covers one container per order, original shipping is not refunded, return shipping is the buyer’s, and opened product can be returned. A first subscription order gets an exchange or store credit within 30 days, with contact within 14 days of delivery. Later subscription orders are “not eligible for a cash refund”, orders placed with a discount code get store credit rather than cash, and Amazon purchases are excluded. Subscriptions renew automatically with a notice three days before each charge; a cancellation has to be made in the account before 8:00 AM Eastern on the charge date.

Trustpilot reviewers describe these terms as the main complaint. They write that subscribers and discount-code buyers were refused cash refunds, that renewal warnings arrive only by email, and that one cancellation request was not honored; one says the subscription is selected automatically on product pages, which we could not confirm from the page text. The brand-site reviews we read in the one- and two-star set contain no billing complaints. A single box bought once, on the brand site or Amazon, avoids the subscription terms.

Who Debloat is for

• Someone who wants a once-a-day powder in a stick rather than capsules or gummies.
• Someone who has read the label and is comfortable buying on species-level information, without strain codes or per-species counts.

If a named strain is the priority, Thorne Bacillus Coagulans is a single-species spore product whose listing does not name the strain either. A two-strain Bacillus gummy with a prebiotic is covered in the Lemme Debloat guide, and the bloating guide starts from the cause instead of the product.

Cost

On the brand site, 30 single sticks or a 30-serving jar is $58.00 one time ($1.93 a serving), or $46.40 on subscribe and save at 20% off ($1.55) with free shipping. The cart shows free shipping from $90, so a one-time order under that appears to pay shipping; we did not find the amount. A 12-stick variety pack is $29.00. On Amazon the 30-count is $58.99 ($1.97) or $53.09 on Subscribe & Save ($1.77).
