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.

How To Use

Since Ozzi is caffeine and sugar free, you can take it at any time your cravings start to hit.

Mix Ozzi with 16-20oz of chilled water.

If you'd like some bubbles, you can mix with ~4oz of still water, then pour in sparkling water on top slowly to avoid foam spilling over.

Pro Tip: Use daily for best results. Start with 1/2 if you have a sensitive gut.

What To Expect

You're fine all day. Then the couch, the quiet, and the evening pull toward the snack drawer. That's the moment Ozzi was built for. Here's how it plays out.

DAY 1: Ozzi works fast. Allulose satisfies your sweet tooth without spiking your blood sugar, and the fiber starts to fill you up, so the evening cookie pull gets weaker.†

DAY 7: Butyrate is feeding your gut lining and the cells behind your fullness hormones.‡ You might notice a steadier appetite and fewer "I'm not even hungry" snack runs.

DAY 30: Your gut and brain are communicating better. Ozzi supports your body's natural GLP-1 and PYY, the signals that tell you you're full, plus a healthy blood-sugar response. Less food goes further.‡

MONTH 2+: Reaching for Ozzi instead of the snack drawer is just what you do now. The habit's stuck, and the benefits keep building.

† Based on ingredient mechanisms: allulose tastes sweet but isn't metabolized like sugar, so it doesn't raise blood glucose; glucomannan, a soluble fiber, forms a gel that promotes fullness.

‡ Butyrate is the primary fuel for gut-lining cells and, with other short-chain fatty acids, stimulates GLP-1 and PYY release from intestinal L-cells in laboratory and animal research. Allulose has been shown to support a healthy post-meal blood-sugar response in human studies at comparable doses. Individual results vary.

Ingredients & Allergies

Ingredients

Ozzi contains 6 clinically studied active ingredients:

Allulose, konjac glucomannan, L-lysine butyrate (BIOMEnd), African mango seed extract, ursolic acid and chromium. The last two are supplied together through Metabolex chromium polyursolate. Each stick also delivers 860% daily value of Chromium.

Other ingredients: Citric Acid, Silica, Natural Flavor, L-Tartaric Acid, Reb M (OnoSweet), Pink Himalayan Sea Salt, and Trisodium Citrate.

5 calories per stick. 0g sugar. No caffeine. No monk fruit. No synthetic dyes or sweeteners.

Allergies

Ozzi is free from dairy, nuts, soy, and monk fruit. Contains no caffeine and no artificial colors.

Despite the name, African mango isn't actually mango. Ozzi uses African mango (Irvingia gabonensis), a seed from a completely different plant family than the common mango (Mangifera indica) you find at the grocery store.

Here's why that matters. The compound behind most mango skin reactions is urushiol, the same irritant found in poison ivy and poison oak. It turns up in common mango because mango sits in the same plant family (Anacardiaceae) as poison ivy, cashews, and pistachios. African mango isn't in that family, so it doesn't carry urushiol.

If you have specific dietary concerns, please review the full supplement facts label or contact us before use.

Natural GLP-1

GLP-1 is a hormone released by your gut after eating. Active GLP-1 is rapidly broken down, with a circulating half-life of roughly 1–2 minutes. That is not the same as receptor binding time.

GLP-1 Agonists, commonly referred to just as "GLP-1", are a pharmaceutical mimic of your natural hormone. They stay active in the body for about a week.

Ozzi is formulated to help support your body's natural GLP-1 secretion.

Here's what customers who've tried GLP-1 medications are saying about Ozzi:

"I cannot say enough about this product. I was on a GLP-1 for 2 years and benefited most from the food noise reduction. I chose to get off of it due to its high cost. I have tried absolutely everything on the market and nothing, absolutely nothing has had the same effect until I came across Ozzi. I am a customer for life! This product is genuinely revolutionary for those who have struggled with ongoing cravings and food noise. I'm locked in. Thank you, thank you!" - Noralyn

"I've been using Ozzi for just a few days now but it definitely curbs my hunger. It's so much more pleasant than the feeling I got from the GLP-1 meds. No nausea at all. And it tastes great too!" - Dan

Not everyone will experience the same results. That's why we offer the 14-Day Ozzi Challenge: take it for 14 straight days, and if your cravings and food noise aren't quieter, we'll refund your first bag.

Why weed gives you the munchies

The munchies aren't a character flaw. They're chemistry.

THC activates CB1 receptors in the parts of your brain that regulate appetite, and it doesn't stop there. A small pilot study in HIV-positive men found cannabis use shifted appetite hormones themselves, including ghrelin, the hormone that tells you to eat [1]. Small study, specific population, so hold it loosely, but it points the same direction as every smoker's lived experience: the same brain that was fine an hour ago is now getting a real hunger signal, aimed mostly at sweet, salty, fatty food.

That matters because it means fighting the munchies with willpower is bringing the wrong tool. You're arguing with a hormone.

What a munchies blocker actually has to do

You can't switch CB1 off without giving up the thing you were enjoying. What a munchies blocker can do is send the opposite signal at the same time. Three of Ozzi's six actives do exactly that.

Konjac fiber fills you up for real. Glucomannan absorbs water and expands in your stomach, and viscous fibers like it slow everything down in ways researchers link to satiety signaling, including the gut's own fullness hormones [2]. It's physical fullness, not a pep talk.

Allulose gives the sweet tooth what it wants without the sugar. 8g of a rare sugar that tastes like the real thing. In a randomized human trial, allulose taken with a sugar load blunted the glucose and insulin response compared to the sugar alone [3]. A second trial using much smaller doses found no significant effect [4], which is exactly the point: the dose decides, and Ozzi carries 8g, not a sprinkle. In mouse studies, allulose also triggered release of GLP-1, the fullness hormone, from the gut [5]. Human confirmation of that hormone effect is still pending, which is why we say Ozzi supports natural GLP-1 production rather than promising numbers.

Butyrate comes at the same pathway from the gut side. Mouse and cell research shows butyrate signaling the L-cells, the gut cells that release GLP-1 [6]. Ozzi carries 500mg of L-lysine butyrate so that signal doesn't depend on what your gut bacteria felt like fermenting today.

How to actually use it for the munchies

Mix a stick into 16oz of cold water before you smoke, or the moment the munchies start. Cold water genuinely tastes better and disperses the fiber more cleanly.

Then let the drink do the arguing. The fullness from the fiber shows up fast. The sweet taste takes the edge off the specific thing the munchies are asking for. And because there's no caffeine and no stimulants in it, a 10pm stick doesn't cost you sleep.

What this won't do

Honesty section. Ozzi won't cancel your high, and it won't make food stop existing. If you sit down with the bag of chips open, the chips still win. The realistic goal is different: the craving gets quieter, a drink replaces the second snack, and you wake up without the regret part.

That's also exactly what the guarantee tests. Take it for 14 straight days, and if your cravings and food noise aren't quieter, we refund your first bag.

What a Doctor Says About Ozzi

Dr. Anand Balasubramanian, MD Verified clinician · Internal medicine · 19 years in practice

"Drink packets curb cravings while promoting healthy blood sugar"

"When late-night cravings hit, I recommend this drink powder as a possible snack replacement. One ingredient I want to highlight is chromium polyursolate. Research on a related form, chromium picolinate, suggests that it may reduce food intake, lower hunger ratings, and decrease fat cravings in overweight women. Chromium can support insulin function and glucose metabolism, which may help keep blood sugar steady enough to avoid triggering cravings. I find this pairs nicely with the African Mango seed extract in this blend, which research suggests may be connected to improvements in body weight, waist size, and fasting blood sugar. Overall, I believe this supplement can be a helpful option for patients looking to manage cravings and support metabolic health."†

Well, my biggest compliment is also a complaint. 🤪 Sometimes I want to eat out of boredom and I can.’t. My body and mouth will not crave anything. Also, true that constancy is key the second week was when it fully kicked in. Will be buying constantly. Will not run out. I refuse. 😊

Edyna R. Verified Customer

Great tasting product! I must confess I was a bit skeptical at first, having tried so many other products in the past. Ozzi definitely cuts down my evening cravings and the watermelon flavor is quite nice!

Vita D. Verified Customer

I love the cherry limeade and watermelon flavors. I drink one in the morning and one in the evening. Basically the times I'm usually craving something sweet. These help me feel satisfied.

Tianna J. Verified Customer

I've been really happy with the product. Not only does it help to curb hunger, but I no longer need my fiber supplements. I don't find the smell off-putting and the taste is great. It's been a winner for me!

Tricia C. Verified Customer

Ozzi does exactly what I wanted it to do - stop my evening munchies. I find it best if I drink it before the munchies have a chance to set in. And yeah - it definitely adds bulk to my "waste management." I already get plenty of fiber, so it took my body a couple days to recalibrate. Both favors are great, with a little zing. So it's a little treat in its own way.

Most buyers say it helps with cravings and the urge to snack at night.

Some buyers mention the powder smells strong when the pouch is opened, which comes from butyrate, our most powerful ingredient.

Many buyers also say the flavors taste good once the powder is mixed and that the smell does not carry into the drink.

    Tino L. Verified buyer

  13. I just started taking Ozzi. But I'm so glad I have!! I bought one tart flavor (Cherry Limeade) and one sweet (Peach Elderflower).
    I'm glad for the heads-up about the slight funky scent, because that would have been a turn off if I wasn't ready.
    I notice the funkiness more in the limeade, but it's not terrible.
    And in the peach? Oh, it's just a lightly sweet drink. I enjoy it, and I'm glad to have this as a healthy choice tool.

    Jessica M. Verified buyer

  14. Love these products. Great flavors as well!

    Shelley G. Verified buyer

  19. I’ve been trying my best to lose 20 to 25lbs and quite literally have had the hardest time and that’s because after I eat a meal I crave something sweet especially at night after I’m off work and once I saw the Ozzi product info I was curious. Mind you i actually started taking this around the time I was due for my monthly cycle which is when my cravings kick in the hardest! And to my surprise I noticed my cravings subsided and my brain was able to stop the noise of falling hard for the cravings even when I wasn’t hungry. I’ll continue to use this product and see how things go!! But I’m off to a great start!

    Aminah m.

  20. Really works! I can usually control my cravings until the night time hunger hits. I've been having 1 Ozzi drink after dinner and I have been able to stop my night time snacking which has finally made it possible to budge the scale back a bit. I'm def ordering more.

The Munchies, Answered

The questions people actually search. More on the FAQ page.

How do you stop the munchies without giving up weed?

Send the opposite signal instead of fighting the craving. THC nudges your appetite hormones toward eat; a viscous fiber drink nudges them back toward full. Mix a stick of Ozzi before you smoke or when the munchies start, and let physical fullness argue with the craving so you don't have to.

It works precisely because it isn't abstinence. You keep the night, you skip the second snack.

Does it work when you're already high?

Yes, that's the normal use case. The konjac fiber expands with water in your stomach within minutes, and the sweet taste handles the specific thing the munchies ask for. You don't need planning or discipline in the moment; you need the stick and 16oz of cold water.

Will it mess with my high?

It's food ingredients: a rare sugar, fibers, a postbiotic, a trace mineral. No caffeine, no stimulants, nothing psychoactive. It changes what your stomach is doing, not what your head is doing.

Why not just eat a real meal instead?

A real meal works, if what you want is a meal at 11pm. Most munchies aren't hunger; they're appetite signaling with the volume turned up. A 5-calorie drink that creates fullness beats a 900-calorie answer to a question your body didn't actually ask.

Does it help with edibles too?

Edibles run longer than smoking, so time it differently: one stick when you dose, and it's fine to mix a second one later in the night if the munchies outlast the first. Each stick is 5 calories, so a second costs you basically nothing.

What's actually in it?

Six clinically studied actives: 8g allulose, 500mg konjac glucomannan, 500mg L-lysine butyrate (BIOMEnd), 150mg African mango extract, and Metabolex chromium bound to ursolic acid. No caffeine, no stimulants, no artificial sweeteners. The full label is on the ingredients page.

Is Ozzi third-party tested?

Yes, and not the vague kind of "tested" the industry likes. Ozzi is certified by Eurofins Healthcare Assurance to NSF/ANSI 173, the American National Standard for dietary supplements (certificate 20260428-0002, all five flavors), and every production lot gets its own Certificate of Analysis: heavy metals, ingredient identity, and a full micro panel. The documents are on our testing and certification page.

Can I take it with my medications?

Ask your doctor first, and we mean that literally, not as fine print. Chromium can affect blood sugar, and viscous fibers like glucomannan can change how some oral medications absorb. Bring the Ozzi label to your appointment; every dose is listed, so it's a two-minute conversation.

What if it doesn't work for me?

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 matter: 14 consecutive days of daily use, the refund applies if your cravings and food noise aren't quieter, and it covers your first bag. Nothing to send back; we don't do returns. Email help@heyozzi.com with your order number within 28 days of delivery.

Studies below tested individual ingredients or other formulations. Open a study to see the amount, population and findings.

Allulose — post-meal glucose and gut hormones

Allulose gives the drink its sweet taste and contributes to the formula’s blood-sugar and gut-hormone rationale. Human trials have found lower post-meal glucose responses at amounts close to the 8 g in one stick.

Effects of D-allulose on glucose tolerance and insulin response to a standard oral sucrose load: results of a prospective, randomized, crossover study.

Ursolic acid — metabolic pathways

Ursolic acid is a plant compound studied for cellular energy pathways. It is one of two actives delivered together in Ozzi through Metabolex chromium polyursolate.

Ursolic acid increases energy expenditure through enhancing free fatty acid uptake and β-oxidation via an UCP3/AMPK-dependent pathway in skeletal muscle.

2015 · Animal and mechanism study

Chu X, He X, Shi Z, Li C, Guo F, Li S, Li Y, Na L, Sun C. · Molecular nutrition & food research

Diet-induced obese rats receiving 0.5% ursolic acid for six weeks, plus cell experiments.

Ursolic acid increased fatty-acid uptake and oxidation through an UCP3/AMPK-linked pathway. The animal experiments also showed lower weight and altered muscle lipid metabolism.

Chromium — appetite and carbohydrate metabolism

Chromium is a trace mineral involved in carbohydrate metabolism. Ozzi supplies it with ursolic acid through Metabolex chromium polyursolate, while explaining the two actives separately.

Effects of chromium picolinate on food intake and satiety.

2008 · Human trial

Anton SD, Morrison CD, Cefalu WT, Martin CK, Coulon S, Geiselman P, Han H, White CL, Williamson DA. · Diabetes technology & therapeutics

42 overweight women reporting carbohydrate cravings; 1,000 mcg elemental chromium as picolinate daily versus placebo for eight weeks; 40 analyzed.

Chromium picolinate reduced measured food intake, hunger and fat cravings compared with placebo. The difference in weight change did not reach statistical significance.
