Appetite Control Pills That Print Their Doses
Five Clinically Studied Actives. Zero Stimulants.
Most appetite pills hide behind a proprietary blend or lean on caffeine so you feel something. Ozzi's capsules do neither: 500mg konjac glucomannan, 500mg L-Lysine butyrate, 150mg African mango, and Metabolex chromium, every dose on the label.
14-Day Ozzi Challenge: Take it for 14 straight days. If your cravings and food noise aren't quieter, we'll refund your first bottle.
Rather drink it than swallow it? The Crave Crusher drink mix is the same core formula plus one more active. Compare the two.
What's in Each Capsule Serving
Five clinically studied actives, every dose printed. Chromium and ursolic acid arrive together as one complex, so they share a card below. No proprietary blend, no caffeine, no stimulants. If a number on this page looks wrong, check it against the label; they match.
500mg
Konjac Glucomannan
A viscous soluble fiber that takes on water and adds volume in your stomach, supporting the physical side of fullness. The largest active in the capsule.
500mg
L-Lysine Butyrate (BIOMEnd)
Postbiotic butyrate bound to an amino acid carrier. Butyrate stimulates the gut cells that release GLP-1 in mouse and cell studies, and supports natural GLP-1 production and gut barrier health. In a 2025 human crossover trial, this form reached peak blood butyrate in 20 minutes.
150mg
African Mango Extract
Irvingia gabonensis seed extract, studied in Cameroon-based trials for effects on leptin, the satiety hormone. We cite that research honestly, limits included, in the editorial below.
10mg
Chromium Polyursolate (Metabolex)
Chromium paired with ursolic acid. Chromium is an essential trace mineral with a well-studied role in insulin signaling, supporting a steady blood sugar response so the crash-then-crave loop has less to work with.

Capsules or Drink Sticks?
Same core formula, two formats. Straight answer: the drink is the slightly stronger product because it carries one more active. The capsules are the one you'll actually take at your desk at 3pm. Here's the honest comparison.
| Capsules | Drink sticks | |
|---|---|---|
| Shared actives | 500mg konjac glucomannan, 500mg L-Lysine butyrate (BIOMEnd), 150mg African mango, and Metabolex chromium with ursolic acid, in both formats | |
| The difference | The shared formula, nothing else | Adds 8g of allulose, a rare sugar that triggered release of the satiety hormones GLP-1, PYY and CCK in a human trial |
| Best for | Swallow and go. Work, travel, anywhere mixing a drink is a chore | The stronger format, and it doubles as the sweet thing you were about to go find |
| Honest tradeoff | One less active than the stick | You have to mix it in water, and the butyrate has a smell some people need a few days to get used to |
| Guarantee | 14-Day Ozzi Challenge, first bottle | 14-Day Ozzi Challenge, first bag |
Capsules still the better fit? Keep scrolling; the buy button above isn't going anywhere. Plenty of customers run both: sticks at home, capsules everywhere else.
Browse the appetite pill shelf on any supplement site and you'll see the same two moves over and over: a proprietary blend that hides how little of each ingredient you're actually getting, or enough caffeine that you feel something even though nothing appetite-related is happening. That's the category. It's why I made the label the entire argument.
What a pill can honestly do about appetite
Your cravings aren't really a willpower problem, they're a signal problem. Appetite runs on three systems: physical fullness in your stomach, hormonal signaling from your gut, and the blood sugar swings that turn a normal afternoon into a hunt for something to eat. A capsule can support all three. It can't override any of them, and a pill that promises otherwise is selling you the caffeine.
The five actives, with the research and its limits
Konjac glucomannan, 500mg. A viscous soluble fiber that takes on water and adds volume in your stomach. The mechanism is physical and same-day. Here's the number most fiber-pill pages won't print: a systematic review of glucomannan trials found the average weight change was not statistically significant (about 0.22kg). We cite that against ourselves on purpose, because fullness support, not the scale, is why it's in the formula. (PMID 24533610)
L-Lysine butyrate (BIOMEnd), 500mg. Butyrate stimulates the gut cells that release GLP-1 in mouse and cell studies, and that species label belongs in the sentence, not a footnote; human confirmation is pending. (PMID 23836895) What is human data: in a 2025 randomized crossover trial (La Monica et al., NCT06700785), this form reached peak blood butyrate in 20 minutes, roughly 5 times tributyrin's peak. Ten participants, single dose, so we call it a pilot rather than proof. Ozzi supports your body's natural GLP-1 production. It is not a medication and doesn't work like one; the full distinction is on our GLP-1 page.
African mango extract, 150mg. Irvingia gabonensis seed extract, studied in Cameroon-based trials for effects on leptin and body measures. Those trials are small and mostly from one research group, so we treat it as a supporting active, not the headline.
Chromium with ursolic acid (Metabolex, 10mg). Chromium's role in insulin signaling has decades of research. On appetite specifically, a controlled human trial found 1000mcg of chromium picolinate reduced food intake in women; our capsule carries a lower chromium dose in a different form, and we'd rather state that gap than borrow the result. (PMID 18715218)
No stimulants, on purpose
Zero caffeine, zero stimulants of any kind. Stimulants are how weak formulas feel strong: your heart rate goes up, you assume it's working, and three weeks later you're tolerant and hungry. A stimulant-free capsule has to earn its keep on the actives, which is the point. It also means you can take it at 8pm without negotiating with your sleep.
The part where I tell you our drink is better
You read that right. The Crave Crusher drink sticks carry the same core formula plus 8g of allulose, a rare sugar that triggered release of the satiety hormones GLP-1, PYY and CCK in a human trial (PMID 35135006). That makes the drink the slightly stronger product, and I'm not going to hide that on the capsule page. The capsules exist because the best formula is the one you actually take every day, and for a lot of people that's a capsule at a desk, not a powder and a glass of water. The full comparison is above. Plenty of customers run both.
The rest is checkable
The capsules hold a 4.6 average from 22 verified reviews on the product page, where the critical ones are published alongside the rest. Our drink flavors are certified by Eurofins Healthcare Assurance to NSF/ANSI 173, and the certificate is on the testing page; that certificate covers the drink, and we say so rather than letting it imply more. Ozzi is recommended by 750+ licensed clinicians through FrontRow Health's verified program, listed on the clinician page. Everything else we've written lives in the guides directory.
And the promise, in writing: 14-Day Ozzi Challenge: Take it for 14 straight days. If your cravings and food noise aren't quieter, we'll refund your first bottle.

What Capsule Customers Say
Yes, I found that it really did reduced my hunger. I was not thinking about food nearly as much. And, I could get thru the afternoon pretty easily, compared to pre-Ozzi use! I am now a subscriber and don't want to go without it!!
Denise G. Verified Loox review
Some days OZZI seems to work better than others but its probable because of the craziness in my life. Love the stuff. It definitely helps to get rid of the food noise.
Martin M. Verified Loox review
LOVE the capsules! I tried the sticks almost a year ago. I could feel the effects, but my partner hated the smell which made it hard to be consistent about it. I can take them at home and at work which has made staying consistent way easier. I struggle with overeating and the capsules really help reduce that consistent food noise and help me stop when I'm full.
Henri B. Verified Loox review
Really does help curb cravings and appetite control. I haven't had any issues with any side effects either.
Tiffany D. Verified Loox review
I take one or two capsules in the morning and I feel full throughout the day. This helps me to not grab a snack or over eat at lunch.
Christina A. Verified Loox review
I take it in the evening when my hunger strikes to keep from eating. It works.

Appetite Control Pills, Answered
The questions people actually search. More on the FAQ page.
Do appetite control pills actually work?
Some do, most don't, and the label tells you which is which. The pills that fail tend to share two features: a proprietary blend that hides the doses, or a stimulant doing the heavy lifting so you feel something even though nothing appetite-related is happening.
The approaches with real evidence are unglamorous: viscous fiber that adds physical volume, and ingredients that work with your body's own satiety signaling. That's what Ozzi's capsules are built from, with every dose printed so you can check it against the research yourself.
What are the best appetite control pills without a prescription?
Honestly, the strongest appetite tools you can get without a prescription aren't pills at all: enough sleep, and enough protein and fiber at meals. Among pills, judge them on four things. Are the doses printed? Is there a stimulant hiding in there? Is it a proprietary blend? And does anything in it have human research?
Ozzi's capsules print every dose: 500mg konjac glucomannan, 500mg L-Lysine butyrate, 150mg African mango, and Metabolex chromium with ursolic acid. No blend, no stimulants, and the research, including its limits, is cited on this page.
Are appetite suppressant pills safe?
The category's safety problems mostly trace to stimulants: caffeine stacks, synephrine, and the older prescription suppressants that got pulled. A stimulant-free, fiber-and-mineral formula sits in a different risk category.
Ozzi's capsules contain no caffeine and no stimulants of any kind. The practical cautions that remain: take glucomannan with a full glass of water, and if you're pregnant, nursing, taking medications, or managing a condition, ask your doctor before starting any supplement. That last sentence isn't boilerplate; it's the honest answer.
What is in Ozzi Crave Crusher Capsules?
Five clinically studied actives per serving, doses printed: 500mg konjac glucomannan, 500mg L-Lysine butyrate (BIOMEnd), 150mg African mango extract, and Chromium Polyursolate (as Metabolex, 10mg), which pairs chromium with ursolic acid.
The capsule shell is vegan-friendly. No caffeine, no stimulants, no artificial sweeteners, no proprietary blend.
Are these an alternative to GLP-1 medications?
No, and we won't pretend otherwise. GLP-1 medications are prescription drugs with clinical weight-loss outcomes. Ozzi is a supplement that supports your body's own natural GLP-1 production, and the butyrate research behind that mechanism is mouse and cell studies, with human confirmation pending.
If you're on a GLP-1 medication or considering one, that's a conversation with your doctor. If you've come off one, we wrote honestly about that transition on our after GLP-1 medications page.
When should I take appetite control capsules?
About 20 to 30 minutes before the window when your cravings usually get loud, with a full glass of water. For most people that's mid-afternoon or early evening; some of our customers take them in the morning to keep the whole day steadier.
No clock rules beyond that. Daily and consistent beats perfectly timed and occasional.
How long do they take to work?
The fiber does its physical work the same day. The rest builds with consistency, which is why our guarantee is written around 14 straight days rather than a magic first dose.
14-Day Ozzi Challenge: Take it for 14 straight days. If your cravings and food noise aren't quieter, we'll refund your first bottle.
Should I get the capsules or the drink?
The drink sticks are the slightly stronger product: same core formula plus 8g of allulose, which has human trial data on satiety hormone release. The capsules are the format you'll actually have with you at work or on the road.
The full comparison is further up this page. Plenty of customers run both.
Do the capsules contain caffeine or stimulants?
No. Zero caffeine, zero stimulants of any kind. You can take them in the evening and go to bed on schedule. That's a fact about the formula, not a claim about your sleep.
What are the side effects?
The honest list is mostly digestive and mostly about the fiber: glucomannan adds bulk, so some people notice gas or a change in bathroom habits for the first few days while their gut recalibrates. Take the capsules with a full glass of water; that matters with any glucomannan product.
In the published human trial of the butyrate form we use, all treatments were well tolerated with zero adverse events, though it was a small single-dose study. If you have a swallowing disorder or any GI condition, talk to your doctor first.
Are appetite control pills FDA approved?
No supplement is FDA approved, ours included, and any pill sold as a supplement that claims to be is misleading you. The FDA regulates supplements under DSHEA: it registers and inspects facilities and polices claims after the fact, but it doesn't review or approve products before sale.
What a careful brand can do is print every dose, skip the proprietary blend, and make claims narrow enough to defend. That's the standard we hold ourselves to on this page.
What's the 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 bottle.
All three parts matter: 14 straight days of use, the condition, and the refund of your first bottle. No return shipping, no forms designed to make you give up.
