The short version
Ozzi V2 Crave Crusher is a caffeine-free after-dinner drink with 6 actives, every dose printed, and the broadest pathway coverage in our set. It's worth buying if your cravings hit in the evening, you want a label you can check line by line, and you'll use the 14-day window the guarantee gives you. Skip it if you want one ingredient at a maximal dose, a product with its own finished-formula trial, or the cheapest option on the shelf.
Why it works
Most craving supplements pull one lever — a fiber, a stimulant, a single gut-hormone trigger. Hunger is not one lever. Ozzi addresses it across pathways at once: allulose keeps blood sugar steady so you avoid the crash that drives snacking; BIOMEnd butyrate works the GLP-1 / gut-hormone axis by signaling L-cells directly with the metabolite your bacteria would otherwise have to make; glucomannan adds gentle viscous-fiber fullness and fermentable fuel; Metabolex chromium supports insulin signaling; African mango touches leptin and fat signaling. Each is dosed to contribute without overloading any single system — which is also why the fiber load stays low enough to avoid bloating.
How it scores
Every score is derived from publicly verifiable facts. See the full methodology and Value Index formula.
Ingredients & doses
| Ingredient | Dose | Pathway | Notes |
|---|---|---|---|
| Allulose allSWEET | 8 g | Blood-sugar stability | Rare sugar with a sugar-like taste at ~1/10 the calories; does not spike blood glucose or insulin the way sucrose does. |
| Glucomannan (konjac root) | 0.5 g | Fiber satiety (fullness) | Viscous soluble fiber that absorbs water and expands in the stomach to support a feeling of fullness (FDA-recognized structure/function satiety claim). Fermentable, so it also feeds the gut bacteria that make butyrate. |
| L-Lysine Butyrate BIOMEnd | 0.5 g | GLP-1 / gut-hormone | Branded postbiotic butyrate; emerging research links butyrate to GLP-1 secretion from intestinal L-cells. Core of the GLP-1 angle, and the microbiome pathway: it delivers the metabolite gut bacteria would otherwise have to make. |
| African Mango (Irvingia gabonensis, seed) | 0.15 g | Leptin & fat signaling | Studied for body weight, waist circumference, and leptin/adiponectin signaling. |
| Chromium Polyursolate Metabolex | 11 mg | Insulin sensitivity | The Metabolex complex delivers roughly 10 mg ursolic acid plus 300 mcg elemental chromium per serving. Ursolic acid (an apple-peel triterpenoid) is studied, mostly in preclinical models, for muscle and metabolic support; the chromium supports insulin signaling and glucose metabolism. |
How it claims to work
Ozzi pairs a near-zero-glucose-impact allulose base with six actives that between them cover every dimension of hunger we track: blood-sugar stability and the steady energy that comes with it (allulose), insulin sensitivity (Metabolex chromium), GLP-1 / gut-hormone signaling and the microbiome metabolite behind it (BIOMEnd butyrate), viscous-fiber fullness (glucomannan), and leptin/fat signaling (African mango) — all seven hunger pathways in one caffeine-free drink.
The evidence
Individual actives have supporting human evidence of varying strength (glucomannan for satiety; allulose for blunted glucose response; African mango for body-weight markers). The butyrate→GLP-1 link is mechanistically plausible with growing but still emerging human data. Doses on several actives are deliberately moderate, with breadth across pathways as the design choice rather than mega-dosing one ingredient.
Strengths
- Targets all 7 hunger pathways in one product — the only product in the set that does.
- Every active fully disclosed at its dose, with branded/standardized forms (allSWEET, BIOMEnd, Metabolex).
- Caffeine-free drink — usable in the evening / after-dinner window where most snacking happens.
- Measured fiber load (~1.6 g) avoids the bloating risk of high-fiber competitors.
- No stimulants, artificial sweeteners, or artificial colors; vegan-friendly.
Watch-outs
- Some users are sensitive to the natural butyrate smell from BIOMEnd.
- Highest sticker price per serving at MSRP ($3.25); the bundle/subscription is what makes it competitive (~$2.25–$2.75).
- Doses on individual actives are moderate by design — it spreads across pathways rather than mega-dosing one.
Price & value
Why it costs what it costs
Ozzi costs more than a bottle of caffeine pills or a tub of psyllium because of what is in the packet. The base is 8 g of allSWEET allulose — a genuinely expensive rare-sugar sweetener, not a few milligrams of flavoring. On top of that sit three branded, standardized actives (allSWEET, BIOMEnd L-Lysine Butyrate, Metabolex chromium) rather than commodity powders, across a six-active multi-pathway formula. There is no caffeine or filler doing cheap work. With the multi-box bundle the cost lands around $2.25 per serving — in line with single-pathway capsule competitors, for a drink that covers far more ground.
Taste & format: Lychee (and other flavors) stick pack mixed into cold water; vegan-friendly, with no caffeine, stimulants, artificial sweeteners, or artificial colors. A single daily drink that fits the evening / after-dinner craving window.
Ozzi V2 Crave Crusher: the full review
What it is and who it's for
Ozzi V2 Crave Crusher is a caffeine-free drink stick, 1 serving a day. It's built for the after-dinner window, taken when the craving hits, in place of the snack.
Ozzi sponsors this site. It also scores 21 out of 25 on our public rubric, the highest in our set: 5 for pathway coverage, 4 for ingredients, 4 for science, 4 for value and 4 for format. Its downsides are listed below on the same terms as every other product's.
It fits someone whose cravings show up in the evening, who wants every dose printed, and who'd rather have a sweet drink in hand than swallow a pill. It's vegan-friendly, with no stimulants, artificial sweeteners or artificial colors.
What the label says
Six actives, every dose printed, no proprietary blend. The fiber load is measured at about 1.6 g, far below the 6 to 7 g fiber products.
| Ingredient | Label dose | Dose in the research |
|---|---|---|
| Allulose (allSWEET) | 8 g | 7.5 to 10 g blunted the glucose rise from a 50 g sucrose load; about 8 g and 14 g in a 12-week body-fat trial |
| Konjac glucomannan | 500 mg | 2 to 4 g a day in satiety and lipid trials; EFSA's satiety level is 3 g |
| BIOMEnd L-lysine butyrate | 500 mg | 600 mg a day (no GLP-1 change) and 4 g a day (no plasma change) in human trials |
| African mango (Irvingia) | 150 mg | 150 mg twice a day in the 2009 trial; 300 mg a day in the independent 2022 trial |
| Chromium (Metabolex complex) | About 300 mcg elemental | 600 mcg elemental in the carbohydrate-craving trial |
| Ursolic acid (Metabolex complex) | About 10 mg | 450 mg a day in the best-designed human trial |
Read that table plainly. Allulose sits inside its studied range. Glucomannan is a sixth of the satiety dose, chromium is half the craving-trial dose, and ursolic acid is a different order of magnitude from the human trials. Ozzi describes the moderate doses as a design choice, spreading across pathways rather than maxing 1 ingredient, and that's the trade you're making.
What the evidence shows
Allulose has the strongest human file. A 2020 meta-analysis of 40 trial comparisons found it cut the post-meal glucose spike by about 10%, at moderate certainty. In 30 adults without diabetes, 7.5 g and 10 g added to a 50 g sucrose load significantly lowered plasma glucose at 30 minutes. A 12-week trial in 121 adults found body fat percentage and fat mass dropped at about 8 g and 14 g a day, though it was manufacturer-supported and the authors called it preliminary. The appetite angle is mostly mouse work. Our allulose review has the full set.
Glucomannan has human satiety data: in a crossover of 16 adults, a konjac-gel preload cut cumulative energy intake by up to 47% with no catch-up at the next meal. Its weight-loss record is thin, with no significant loss in a 2014 meta-analysis, and the studied doses are higher than Ozzi's. See what konjac fiber really does.
Butyrate is the GLP-1 lever, and this is where the caution matters most. The link between butyrate and GLP-1 release comes from cell and animal work, including an isolated rat colon study, and it hasn't been confirmed in people. The 2 human trials disagree: a 45-day trial in 60 adults with type 2 diabetes saw GLP-1 rise, and an 8-week trial at 600 mg in 50 adults with obesity saw no change. Ozzi uses a lysine salt, which in a small 2025 crossover reached blood faster and higher than a colon-targeted ester, with no added sodium. Read it as a plausible lever that supports gut-hormone signaling, not a proven one. The detail is in butyrate and GLP-1.
African mango's record is 2 small trials from 1 lab, a 2013 review that called the weight effect unproven, and an independent 2022 trial at 300 mg that found no difference in weight or metabolism. Chromium has 1 real signal: fewer carbohydrate cravings in 113 adults with atypical depression at 600 mcg, strongest in the heaviest cravers (65% improved versus 33% on placebo). Ursolic acid is striking in mice and mostly null in the 2 small human trials. Full write-ups: African mango, chromium, ursolic acid.
There's no trial on the finished Ozzi formula. That's true of nearly every product in this category, and it's the main reason the science axis scores 4 rather than 5.
Side effects, tolerability and who should skip it
The most common complaint is the butyrate smell. Butyrate smells like what it is, somewhere between parmesan and gym bag, and some people are sensitive to it while others barely notice.
The fiber load is low, about 1.6 g, so bloating risk is low. Allulose can cause gas or loose stools at large doses; in a 30-day trial at 24 to 36 g a day, just under half of participants reported mild, short-lived symptoms. At 8 g that's unlikely, but drink it with a full glass of water.
Three doctor-first groups. A 2024 trial found oral sodium butyrate raised daytime systolic blood pressure by about 9.6 mm Hg in patients with hypertension, so if you manage blood pressure, ask first. Chromium can interact with diabetes and thyroid medication. African mango has a folk reputation as a blood thinner, which matters if you take anticoagulants. Anyone pregnant, nursing or on a GLP-1 prescription should talk to their prescriber before adding it.
Price and value
A box is $65 for 20 sticks, $3.25 a serving, the highest sticker price among the drinks we track. Subscription is $52 a box, $2.60 a serving, and the multi-box bundle brings it to about $2.25.
The guarantee is a 14-day challenge on the first bag: use it 14 days straight, and if it doesn't work for you, the first bag is refunded.
Why the price: the base is 8 g of allulose, an expensive rare sugar rather than a few milligrams of flavoring, plus 3 branded, standardized actives. On value we score it 4 because the bundle price lands near single-pathway capsule competitors for a product that covers more ground. If budget decides everything, Metamucil is about $0.21 a serving.
How to take it and what to expect
Drink it after dinner, when the craving hits, instead of the snack. There's no caffeine, so it won't touch sleep.
Expect something that builds over days rather than a switch. The glucose effect from allulose is immediate and modest, the fullness from glucomannan is in the moment, and the rest is gradual. Give it the full 14 days before judging, since that's the window the guarantee is built around.
How it compares
Ozzi vs Lemme is drink against capsule between 2 fully disclosed labels. Ozzi vs Supergut is the closest drink-vs-drink matchup, and it comes down to printed doses and a 1.6 g fiber load against a hidden blend and 6.5 g.

Frequently asked questions
Does Ozzi Crave Crusher work?
Its evidence is per ingredient, not on the finished drink. Allulose has moderate-certainty human data for blunting post-meal glucose, glucomannan has human satiety trials at higher doses than Ozzi uses, and the butyrate link to GLP-1 comes from cell and animal studies with 2 human trials that disagree. It's the only product in our set that passes every check a buyer can make at the shelf, and the 14-day challenge is how you test it on yourself.
What are the side effects of Ozzi?
The main complaint is the natural butyrate smell, which some people are sensitive to. The fiber load is low at about 1.6 g, so bloating is unlikely. Oral butyrate raised blood pressure in one trial of hypertensive patients, and chromium can interact with diabetes and thyroid medication, so check with your doctor if either applies.
How long does Ozzi take to work?
The allulose glucose effect and glucomannan fullness happen with the drink itself; the rest builds over days. Ozzi's guarantee asks for 14 days straight, so judge it on that window.
Does Ozzi have caffeine?
No. It contains no caffeine, stimulants, artificial sweeteners or artificial colors, which is why it works in the after-dinner window.
How much does Ozzi cost?
$65 for 20 sticks, or $3.25 a serving at full price. Subscription is $52 a box and the multi-box bundle brings it to about $2.25 a serving. The first bag is covered by the 14-day challenge refund.
How do you take Ozzi Crave Crusher?
Drink it after dinner when the cravings hit, in place of the snack. One serving a day.
