The short version: Ozzi Crave Crusher is a caffeine-free drink stick you mix into cold water once a day. It uses six clinically studied ingredients, led by 500mg of BIOMEnd L-lysine butyrate and 8g of allulose, to support your body's natural GLP-1 production and quiet cravings. One stick is 5 calories. It's vegan, gluten free, and stimulant free. Most orders ship the next business day and arrive in the US in 2 to 4 business days.

How Ozzi works

The mechanism, in plain language.

How does Ozzi work?

Ozzi works on cravings from three directions at once instead of trying to out-muscle them.

1. It supports natural GLP-1 production. GLP-1 is the hormone your gut releases after you eat that tells your brain you've had enough. The butyrate in Ozzi (BIOMEnd L-lysine butyrate) is a short-chain fatty acid that stimulates the L-cells in your intestine, the cells responsible for releasing GLP-1 and PYY. The chicory root inulin feeds the gut bacteria that make more butyrate on their own, so you get the compound directly and the fuel to produce it.

2. It creates physical fullness. Glucomannan is a soluble fiber from konjac root that absorbs water and expands in your stomach. That's real volume, not a trick.

3. It handles the sweet part. Allulose tastes like sugar and satisfies the craving, without the blood sugar spike that sends you looking for the next thing an hour later. Chromium supports insulin sensitivity so glucose gets handled properly.

Most people drink it in the late afternoon or after dinner, before the cravings usually start. The point is to stop fighting yourself at 9pm, not to add willpower you don't have.

How long does it take to work?

Some people notice a difference the first night. For most it takes a week or two of daily use before the change is obvious, which is exactly why the guarantee runs 14 straight days.

The fullness from the fiber is immediate. The gut and hormone side builds with consistent use, so skipping days works against you.

Is Ozzi a weight loss product?

No. Ozzi is a dietary supplement that supports appetite control, not a weight loss drug, and we don't claim it makes you lose weight.

What it does is take the cravings and the food noise down enough that whatever you're already doing (a calorie deficit, better sleep, a walk after dinner) gets easier to stick to. Customers who tell us it changed the scale changed something else too.

Where can I learn more about the science behind Ozzi?

Start with the ingredients page: heyozzi.com/pages/ingredients. It breaks down all six actives, the dose of each, and what the research supports.

For deeper reading, the butyrate guide covers the short-chain fatty acid at the center of the formula, including the human head-to-head absorption trial and the parts of the data that don't flatter us. The natural GLP-1 page covers the hormone itself.

GLP-1, explained

The most misunderstood part of this category.

What is GLP-1?

GLP-1 (glucagon-like peptide-1) is a hormone your own body makes. It isn't a drug and it isn't new. Specialized cells in your small intestine called L-cells release it when food arrives, and it does three things: it tells your brain you're satisfied, it slows how fast your stomach empties, and it helps your body manage blood sugar after a meal.

Everyone produces GLP-1. It has a short half-life, measured in minutes, so levels rise around meals and fall back down quickly.

What's the difference between natural GLP-1 and a GLP-1 agonist?

This is where most of the confusion in this category lives, and a lot of brands are happy to leave it there.

Prescription GLP-1 medications are agonists. They're engineered molecules that bind to the same receptor your natural GLP-1 uses, but they're built to resist the enzyme that breaks the hormone down. That's the whole trick: instead of a signal that lasts minutes, you get one that lasts days. They're dosed by a doctor, they've been through clinical trials for that purpose, and they carry documented side effects.

Natural GLP-1 support is a different thing entirely. Ingredients like butyrate and soluble fiber work upstream, on the L-cells that release your own hormone. You're not replacing the signal, you're supporting the one you already make. It's your body's own hormone, at your body's own duration.

Those are not the same mechanism, and they don't produce the same magnitude of effect. Anyone selling a supplement while implying it matches prescription-level results is lying to you. Ozzi is built for people who want natural support, not a substitute for a prescription. If you want prescription-level results, that's a conversation with your doctor, and we'll tell you that plainly.

Can I take Ozzi if I'm on a GLP-1 medication, or coming off one?

Talk to your doctor first. That's not a dodge, it's the only honest answer when a prescription is involved.

A lot of our customers come to us after stopping a GLP-1 medication, when appetite comes roaring back and they want ongoing support. Ozzi has no stimulants and no drug interactions we're aware of, but your prescriber knows your situation and we don't.

Ingredients and doses

Everything in the stick, with the numbers.

What are the active ingredients in Ozzi, and at what doses?

Six actives, plus supporting fiber. Per one stick (one serving):

IngredientDose per stickWhat it's there for
Allulose (as allSWEET)8gRare sugar that tastes like sugar and supports natural GLP-1 release, without the glucose spike
L-Lysine Butyrate (as BIOMEnd)500mgPostbiotic short-chain fatty acid; stimulates intestinal L-cells for GLP-1 and PYY secretion, supports the gut barrier
Glucomannan (konjac root)500mgSoluble viscous fiber; absorbs water and expands in the stomach for fullness
Chicory Root Inulin500mgPrebiotic fiber; feeds the gut bacteria that produce butyrate naturally
African Mango Extract (Irvingia gabonensis, seed)150mgStudied for leptin signaling and metabolic markers
Chromium (as Metabolex Chromium Polyursolate)300mcgEssential trace mineral; supports insulin signaling and blood sugar control
Ursolic Acid (as Metabolex Chromium Polyursolate)10mgPlant compound studied for fat metabolism; carries the chromium in the same complex
Highly Branched Cyclic Dextrin (as Cluster Dextrin)500mgSpecialized carbohydrate used for smooth mixing and steady delivery

Other ingredients: citric acid, natural flavor, L-tartaric acid, Reb M (as OnoSweet, from stevia), pink Himalayan sea salt, trisodium citrate, silica.

How many calories are in Ozzi?

5 calories per stick. That's the whole serving, not a per-100ml technicality.

The reason it can taste sweet at 5 calories is allulose. Allulose is a rare sugar, meaning it occurs naturally in small amounts in foods like figs, raisins, and maple syrup. It's structurally almost identical to fructose, so your tongue reads it as sugar and it behaves like sugar in a drink: it dissolves the same way and it tastes like the real thing rather than like a sweetener.

The difference is what happens after you swallow it. Your body absorbs allulose in the small intestine but barely metabolizes it, so most of it passes through and leaves in urine instead of being burned or stored. That's why it lands around 0.4 calories per gram, roughly a tenth of table sugar, and why the FDA allows it to be excluded from the "total sugars" and "added sugars" lines on a nutrition label.

It also doesn't spike blood glucose or insulin the way sucrose does. Research suggests allulose may support healthy after-meal blood sugar responses. So you get the sweet part of the craving handled without the spike-and-crash that usually sends you back for more 45 minutes later.

Does Ozzi have any caffeine or stimulants?

No. Zero caffeine, zero stimulants of any kind.

This was deliberate. Most people take Ozzi in the evening, which is exactly when the cravings hit, and a stimulant would wreck their sleep. There's also nothing in here that's a stimulant in disguise: no green tea extract, no yohimbine, no synephrine, no guarana. It won't give you jitters and it won't keep you up.

Does Ozzi contain berberine or artificial sweeteners?

No berberine, no sucralose, no aspartame, no acesulfame potassium. The sweetness comes from allulose plus a small amount of Reb M, which is the sweetest-tasting compound in the stevia leaf and the one that doesn't carry the bitter aftertaste stevia is known for.

No artificial colors and no artificial flavors either.

Taking it

When, how much, and what to expect.

How do I take Ozzi?

Pour one stick into 12 to 16oz of cold water, stir or shake for a few seconds, and drink it. Cold water matters more than people expect: it tastes noticeably better and the fiber disperses more cleanly.

Always drink it fully dissolved in liquid. Glucomannan is a viscous fiber that expands with water, so it belongs in a full glass, never taken dry.

When's the best time to drink it?

Whenever your cravings usually win. For most customers that's late afternoon or right after dinner, roughly 30 to 60 minutes before the snacking normally starts.

Some people prefer it in the morning to steady out the whole day. Both work. Consistency matters more than timing.

Can I take more than one stick a day?

One stick a day is the serving we formulated and tested around, and it's what we recommend. Doubling up doesn't double the effect, and the fiber is the part most likely to give you gas if you overdo it.

Plenty of people go the other way. Several customers use half a stick and find that's plenty for them.

What does Ozzi taste like?

Sweet and fruity, closer to a flavored drink than to a supplement. It's built to work as the treat, which is the whole idea: you're replacing a snack, not adding a chore.

Mixed in cold water it's light, not syrupy. Less water makes it sweeter, more water makes it more refreshing, so adjust to taste.

What's the difference between the drink sticks and the capsules?

Same core idea, different format. The drink sticks include the allulose, so they handle the sweet craving directly and give you something to drink in the moment. The capsules drop the allulose and the drink experience and keep the actives, for people who'd rather swallow a pill than mix a glass.

If your problem is specifically sweet cravings at night, take the sticks. If you want the ingredients without the ritual, take the capsules.

Side effects and safety

The honest version, including the parts that aren't flattering.

Will Ozzi make me nauseous?

It can, and there are two separate reasons why.

The first one is the mechanism working. Ozzi is designed to support natural GLP-1 production, and GLP-1 is a hormone that can make you feel a bit nauseous. That's a known property of the hormone itself, not a flaw in the formula. If you feel mildly queasy the first few days, that's usually what's happening, and it typically settles as your body adjusts.

The second one is simpler: in rare cases an ingredient just doesn't sit well with a particular person. If that's you, stop taking Ozzi immediately. Don't push through it. Email help@heyozzi.com and we'll take care of you.

Drinking it with a full glass of water, and not on a completely empty stomach, helps for most people.

What are the side effects of Ozzi?

Most people have none. The ones that do report something almost always report digestion: gas, bloating, or looser stools in the first few days. That's the fiber, and it usually settles within a week.

Here's what's reported for each active, so you can judge for yourself:

  • Allulose (8g). At high intakes it can cause gas, bloating, or loose stools, since the portion your body doesn't absorb ferments in the gut. Tolerance studies generally put the threshold well above a single 8g serving, which is why we kept it there.
  • Glucomannan (500mg). Gas, bloating, and softer stools are the common ones. Always take it dissolved in a full glass of liquid; viscous fibers taken dry can swell in the throat or esophagus.
  • Chicory root inulin (500mg). The most likely source of gas and bloating, especially if you have IBS or you're sensitive to FODMAPs. 500mg is a small dose (research trials typically use 7 to 12 grams), but sensitive guts are sensitive.
  • L-lysine butyrate (500mg). Generally well tolerated. In the published human absorption trial all butyrate forms were tolerated with no adverse events, though that was a single dose in 10 people. Mild GI upset is the occasional report.
  • African mango extract (150mg). Trials have reported headache, gas, and trouble sleeping in some participants. Those trials used doses much larger than 150mg.
  • Chromium (300mcg). Rare reports of headache, mild GI upset, or sleep disturbance. 300mcg sits within the range commonly used in supplements and well below levels associated with problems.

The pattern here matters: our doses are on the conservative side of what the research uses, so the risk of any of this is low. Low is not zero. Some people are simply more sensitive, and a few will react to something no matter how small the dose. If Ozzi doesn't agree with you, stop taking it and talk to your doctor.

Who shouldn't take Ozzi?

Talk to your doctor before starting Ozzi if you're pregnant or nursing, under 18, managing a medical condition, or taking prescription medication, including anything for blood sugar. Chromium and soluble fiber can both affect how your body handles glucose, and fiber can affect how other medications are absorbed, so spacing Ozzi a couple of hours from prescriptions is a reasonable precaution to ask your pharmacist about.

If you have IBS, SIBO, or a diagnosed sensitivity to fermentable fibers, start with half a stick.

Is Ozzi FDA approved?

No dietary supplement is FDA approved, including Ozzi. The FDA doesn't approve supplements the way it approves drugs; it regulates them as food, which means the manufacturer is responsible for safety and for the accuracy of the label.

Any supplement brand claiming FDA approval is misrepresenting how the system works.

Diet and allergens

Quick answers.

Is Ozzi gluten free?

Yes. Ozzi is gluten free.

Is Ozzi vegan?

Yes. Every ingredient in Ozzi is plant-derived or mineral. No animal products, no gelatin, no dairy.

Is Ozzi keto friendly? Does it break a fast?

At 5 calories and with allulose as the sweetener, Ozzi fits comfortably into a ketogenic diet. Allulose isn't metabolized like sugar and doesn't raise blood glucose the way sucrose does.

On fasting: strictly speaking, anything with calories technically breaks a fast. 5 calories is about as close to nothing as a flavored drink gets, and most people doing intermittent fasting for appetite reasons treat it as fine. If you're fasting for a specific medical protocol, follow your protocol.

Does Ozzi have any sugar?

No added sugar. The sweetness is allulose plus a small amount of Reb M from stevia. Allulose is a sugar by chemistry but the FDA permits it to be excluded from the total and added sugars lines on the nutrition label, because your body doesn't metabolize it as one.

Guarantee and returns

The terms, stated in full.

What is the Ozzi guarantee?

14-Day Ozzi Challenge: Take it for 14 straight days. If your cravings and food noise aren't quieter, we'll refund your first bag.

All three parts of that matter. It's 14 consecutive days of daily use, the refund applies if your cravings and food noise aren't quieter, and it covers your first bag (first bottle, for capsules).

The 14 days aren't a hoop. The gut and hormone side of this builds with consistent use, and two weeks is the shortest honest window to judge it in.

There's no return policy to navigate, because there are no returns. You keep the bag either way. Refunds are valid within 28 days of delivery.

How do I request a refund?

Email help@heyozzi.com with your order number and confirm you used Ozzi daily for two weeks straight. That confirmation is the whole requirement.

Two things to know. Refunds are valid within 28 days of delivery, so don't sit on it. And there's nothing to send back: we don't do returns, so keep the bag, opened or not.
