If you’re dealing with a lingering cough, thick mucus, or years of smoking behind you, a capsule that promises clean lungs is hard to ignore. OmniBreathe’s headline goes right at that hope, promising to “Naturally Cleanse Your Lungs” in “Just 3 Days!”
Mucus does a real job in your airways, but too much of it can leave you congested, and polluted air and smoke are hard on anyone’s lungs. So I understand the appeal. I wanted to know if two capsules a day can do what the ads say.
For this OmniBreathe review, I went through its offer pages, its two long sales stories, and the buyer quotes it shows. I also read what Memorial Sloan Kettering and the National Institutes of Health say about NAC, quercetin, cordyceps, and bromelain, what the FDA says about supplements, and what the CDC says about quitting.
A low-cost daily capsule built around NAC, vitamins, and plant extracts. It’s easy to take, but treat it as an experiment and not as lung treatment, because the ads go far beyond the evidence.
- Simple routine of 2 capsules a day
- Includes NAC, which has lung research behind it, with mixed results
- About $1.33 a day or less before shipping
- Free US shipping advertised
- No published trial of the product that I could find
- Ingredient amounts aren’t on the offer pages
- Three-day cleanse claim has no support I could find
- Not a replacement for asthma or COPD medicine
- 90-day guarantee advertised, but I couldn’t read the terms
Quick Verdict
OmniBreathe is an easy supplement to take, at roughly 89 cents to $1.33 a day before any shipping, and NAC is the most interesting thing in it. Some buyers are happy with it. But I found no published trial of OmniBreathe itself, and nothing that backs a three-day lung cleanse. If you have asthma or COPD, please don’t let it replace your inhaler or your prescriptions.
OmniBreathe – Overview
Air pollution matters more for people with lung conditions like asthma, but it isn’t only their problem. OmniBreathe plays to that worry with a simple story: your lungs are clogged, and these nutrients will clear them. Below is the product as sold. Whether the story holds up comes later.

What is OmniBreathe?
It’s a daily capsule sold as a natural lung cleanser. The brand’s label calls it “A blend of herbs and biochemical compounds for healthier lungs,” and that’s the plainest description you’ll get from it.
The sales pages go a lot further. OmniBreathe is said to clear mucus buildup, strengthen bronchial health, and “Flush out toxic tar.” It’s aimed at people dealing with congestion, allergies, or the effects of smoking. The brand also says it has sold “50,000+” bottles. I can’t check that number, and sales wouldn’t tell you whether it works anyway.
Its founder story is about Dasi Lin, whose grandfather had chronic lung problems. The page says Dasi worked with “top naturopaths and respiratory specialists” on the formula. It doesn’t name any of them, so I read that as a marketing story.
It’s a supplement, not a drug. The FDA says it “does NOT have the authority to approve dietary supplements for safety and effectiveness, or to approve their labeling, before the supplements are sold to the public.” Nobody at the FDA checked whether this formula does what the ads say before it went on sale.
What’s Inside OmniBreathe: Ingredients and Their Benefits
The brand calls these “just a few of the supernutrients,” and one landing page ends its list with “Plus more 100% natural ingredients.” That’s my first complaint. Without amounts or a complete list, you can’t compare it to the studies, or to a plain NAC bottle.
A listing I found in search describes a version with mullein, ginger, CoQ10, and 600 mg of NAC, taken three times a day, and one of the brand’s stories mentions selenium. I couldn’t confirm any of those on the offer pages, so check the Supplement Facts panel on your bottle. Below is what I found on each named ingredient. The research is on the ingredients, not this capsule.
Vitamin A
You need vitamin A, and the brand says it supports lung function. It doesn’t say which form or how much.
Smokers should pay attention to this one. Research listed on PubMed looked at beta-carotene, which your body can turn into vitamin A, and trials found supplements raised lung cancer risk in smokers. I only saw a summary of that research, and I don’t know what form OmniBreathe uses. If you smoke, skip it unless your doctor agrees.
Vitamin C
Vitamin C is an antioxidant your body needs, and the brand groups it with vitamins A and D as support for “optimal lung function.” That’s a general claim about a common vitamin, and you can get it cheaply elsewhere. I wouldn’t count it as a reason to buy this particular bottle.
Quercetin
Quercetin is a plant pigment found in onions, berries, and citrus. The brand calls it an antioxidant “that protects your lungs,” and one sales story says it “clears up toxins trapped in lung tissue.” I couldn’t find support for that second line.
Memorial Sloan Kettering’s page says, “Quercetin has not been shown to treat cancer or other diseases.” It also describes a man on warfarin whose blood test numbers rose after he added quercetin, so talk to your doctor first if you take a blood thinner.
N-acetyl-L-cysteine (NAC)
This is the ingredient I’d look at first, since mucus is what most buyers want help with. NAC is an amino acid compound, and it’s the one with the most relevant research here.
Even so, Memorial Sloan Kettering is careful about it: “Results with NAC for chronic lung disease are mixed.” It adds that “a meta-analysis suggests it is not the most effective mucolytic agent for COPD.”
The same page lists stomach upset, diarrhea, nausea, vomiting, and skin rash as common side effects, and it names low blood pressure, severe allergic reactions, and asthma attacks among other possible ones. It says not to take NAC with nitroglycerin. It also mentions an animal study in which NAC “appeared to accelerate lung cancer growth.” That’s an animal result, not proof of harm in people, but it isn’t what a smoker expects from a lung cleanser.
Bromelain
Bromelain is an enzyme from pineapple. The brand says it “reduces tissue damage and edema in lungs,” and that’s a big claim. I found little human evidence for it on lungs.
The National Institutes of Health’s page doesn’t discuss lungs or asthma at all. On a nearby question it says, “There is not enough high-quality research to say whether oral bromelain should be recommended for sinusitis.” It lists stomach upset and diarrhea as the most common side effects.
Cordyceps Extract
Cordyceps is a fungus long used in traditional Chinese medicine, and the brand says it’s “been shown to provide better lung function and quality of life.” Memorial Sloan Kettering’s page doesn’t list lung conditions among its main uses, and it warns that cordyceps can lower blood sugar and may raise bleeding risk. If you take insulin or a blood thinner, that’s a reason to ask before you start.
Vitamin D
The brand groups vitamin D with A and C, and says these vitamins support lungs and “restore those critical vitamins lost by smoking.” I couldn’t find a source on the page for that.
Vitamin D is common and cheap on its own. Without the amount, I can’t say whether what’s in here would add anything to what you already get.
How Does OmniBreathe Work?
The directions are easy. The brand’s steps are “Take 2 capsules daily” and “Go about your life like normal,” and its FAQ adds 8 oz of water, preferably with food.
The brand’s explanation is that the nutrients are absorbed into your bloodstream, travel to your lungs, and “loosen and flush out nasty toxins and suffocating tar buildup.” It promises benefits “within 24-72 hours,” with “Full lung cleansing effects” after 2-4 weeks.
I found no study showing that this capsule, or any capsule, flushes tar out of human lungs in three days. The before-and-after lung art on its sales material is vivid, but it isn’t evidence. The most I’d take from the research is that NAC may help some people with mucus.
Benefits of OmniBreathe
The brand lists a lot of benefits. Here’s how far I’d trust each.
Cleansing your lungs
This is the main promise, and it’s the one I trust least. “Cleanse” and “detox” sound specific, but the pages never say how anyone measured it. They show no scan, no lung function test, and no study on the product.
Provides essential nutrients
Vitamins A, C, and D are essential nutrients, so this one is fair as far as it goes. It only helps if you’re short on them, though, and the amounts aren’t on the offer pages. A blood test from your doctor would tell you more than a sales page can.
Balance mucus production
NAC makes this the most believable claim, because it has been studied for mucus. I don’t know the dose, though, and the brand’s “No more congestion, wheezing, or suffocating mucus buildup!” goes well past anything I read.
Anti-inflammatory action
The brand says the formula will “soothe inflammation and irritation.” Some of the ingredients have been studied for inflammation, but I found nothing showing what this capsule does to inflamed airways. I’d treat this as a possibility and not a result.
Pros and Cons of OmniBreathe
These are based only on what I could check.
Can OmniBreathe Replace Drug-Based Medication?
No, and this is the part of the page I care about most. OmniBreathe’s landing page says, “It’s time to say goodbye to drugs and chemicals that don’t improve your health or address the root of the problem.” It also says it “relieves asthma and COPD symptoms.”
Compare that with the fine print on one of its sales stories: “These products are not intended to diagnose, prevent, treat, or cure any disease.” They can’t both be right, so go with the fine print. I’d weigh the brand’s comparison this way:
- Speed: The brand says it “Works Fast.” Rescue inhalers are built for fast relief, and a capsule with “24-72 hours” in its pitch isn’t a stand-in for one during an attack.
- Natural ingredients: Natural doesn’t mean free of risk. The National Institutes of Health’s asthma page says, “Herbs can have side effects, some of them serious, and some herbs may interact in undesirable ways with medicines that are used to treat asthma.”
- Lasting benefits: The brand says “LONG-LASTING,” and I saw no long-term data to back that.
That same page says, “Evidence does not support using complementary health approaches instead of proven medical management for asthma.” So if you want to try OmniBreathe, add it with your doctor’s OK. Don’t swap anything out. The FAQ on its sales story says it’s “safe to take with most medications,” and that isn’t enough for me, given the interactions I listed above.
Will OmniBreathe Help You Quit Smoking?
I wouldn’t count on it. One landing page is titled “The All-Natural Way to Quit Smoking For Good,” and a sales story says it makes it “Almost Impossible NOT To Quit!” That story centers on a woman named Katie. Its fine print says, “All persons depicted on this site are models.”
The same page says you can keep smoking while you take it and your lungs will still “slowly get stronger.” I’d be very wary of that line, because it makes it easier to put off quitting. I found no study of OmniBreathe on smoking, and the page doesn’t cite one.
The CDC’s quit page lists options with real support, including nicotine patches, gum, and lozenges, along with prescription pills you can discuss with your doctor. Counseling helps too, and you can call 1-800-QUIT-NOW for free support. Even one of its own quoted buyers says quitting comes first. That line is in the reviews below.
OmniBreathe Claims Vs What I Found
| Claim | What I found | Where I checked |
| “In Just 3 Days!” | No study or measurement is shown for this. Buyers quoted by the brand mention “a couple of days” and “five (5) days,” which are personal reports. | Offer pages |
| “FDA-APPROVED FACILITY” | Its other pages say “FDA-registered.” I couldn’t confirm either one. The FDA says it doesn’t approve supplements before sale, so I wouldn’t read this as approval of the product. | Offer pages, FDA |
| “no side effects” | Memorial Sloan Kettering lists side effects for NAC, and the National Institutes of Health does for bromelain. A sales FAQ says “There are no known side effects.” I wouldn’t repeat that. | Sales story, MSK, NIH |
| “clinically proven” | I found no trial on the finished product. The research I read is on some ingredients, and it’s mixed. | Offer pages, MSK |
| “COMPLETELY SAFE” | NAC, quercetin, and cordyceps all carry drug interaction warnings on Memorial Sloan Kettering’s pages. | Landing page, MSK |
| “Quit Smoking Naturally – For Less Than $1 Per Day!” | On that page’s data, you’d need the five-bottle deal at $149.85 to get just under $1. One bottle at $39.95 works out to about $1.33. The quitting claim itself has no study behind it that I could find. | Quit smoking page, offer page |
| “my doctor had seen incredible success” | This comes from a grandmother’s story on a page labeled “THIS IS AN ADVERTISEMENT AND NOT AN ACTUAL NEWS ARTICLE.” Its results are described as “illustrative.” | Sales story |
Who Should Buy OmniBreathe, And Who Should Skip It?
You might consider it if you’re:
- A healthy adult curious about a NAC-based supplement
- Fine with modest or no results, and clear that it’s an experiment
- Willing to read the label and get the refund terms in writing first
I’d skip it, or talk to your doctor first, if you:
- Have asthma or COPD and hope to use fewer of your medicines
- Smoke, because of the vitamin A question above
- Take nitroglycerin, a blood thinner, insulin, or other regular medicine
- Are under 18, pregnant, or nursing, since I saw no guidance for you on these pages
If you’re short of breath, coughing up blood, or getting worse, get medical care now and don’t try a supplement.
OmniBreathe Pricing
These are the prices I saw on the offer page my links go to, on November 7, 2026:
| Option | Total | Bottles | Per day |
| One bottle | $39.95 | 1 | About $1.33 |
| Buy 1, Get 1 50% OFF | $59.93 | 2 | About $1.00 |
| Buy 2, Get 1 FREE | $79.90 | 3 | About 89 cents |
The per-day numbers are my math, at 2 capsules a day. Other offer pages price the same “Buy 2, Get 1 FREE” deal at $99.90 and add a five-bottle “Buy 3, Get 2 FREE” deal at $149.85, so the link you land on matters. Free shipping is advertised for the USA, but the page data also lists $7.99 shipping on some entries, including the single bottle. Check the total at checkout. I wouldn’t buy a three-bottle bundle first. If it doesn’t help you, you’re left with a return to sort out and two extra bottles.
Is OmniBreathe Legit or a Scam?
It looks like a real product, so I wouldn’t call it a scam. My concern is the marketing, which goes much further than the evidence I could find.
What I could and couldn’t check:
- Trustpilot: I found no profile for it, so there’s no independent score to go on.
- BBB: A search for “OmniBreathe” showed “No results.” That leaves no record either way, and the company could be listed under another name.
- Company details: The pages say “American Company,” “Made In NYC,” and list support@omnite.com. Still, omnite.com only redirected to a blank lander page for me, omnibreathe.com wouldn’t load, and I saw no street address on the offer pages.
- The sales stories: Both say at the bottom that they’re advertising. The grandmother’s story calls its results “illustrative,” and the quit-smoking story says its people are models. Don’t read them as news or patient reports.
- The refund: The 90-day vs 30-day gap is in the table above, so ask support to email the terms before you order.
A review I could only see in a search summary, on a reseller’s listing, reported stomach cramps and a refused refund. That’s one person, and I can’t verify it, but it’s why I’d get the refund terms first.
Where to Purchase OmniBreathe?
My links go to the brand’s offer page, which says buying there is “buying directly from OmniBreathe.” It’s the place to get the prices above and the advertised guarantee.
It isn’t the only place. The same page mentions “3rd-Party retailers,” its buyer quotes link back to Amazon reviews, and I saw other sellers in search results. If you buy elsewhere, check the seller and don’t assume the 90-day guarantee comes with it.
What Customers Say About OmniBreathe
One of the brand’s pages shows “4.2 stars” and “(869)” reviews, without saying where that number comes from. The quotes below all come from its offer page, which links them to Amazon reviews. I couldn’t confirm them on Amazon, and they’re the brand’s own picks, so expect the good ones.
Two happy buyers:
Steven wrote, “Those illnesses left me with a lot of chest and lung congestion that I was having trouble getting rid of. This product helped a lot with that and I will definitely use again!”
Karen A. Durham wrote, “it took only five (5) days to notice a difference. My breathing is much better.”
And one with advice worth hearing:
Sheryl S., a long-time smoker with COPD, wrote, “The best thing is to quit smoking but this helps.” I think that’s the most useful line on any of its pages.
The rest of that review also says, “I don’t need my inhaler as often.”
That line needs a warning, and so does another buyer with asthma who says, “I don’t even have to take my preventative med any more.” Those are personal stories, and I wouldn’t follow them. Please don’t cut back on an inhaler or a controller medicine without your doctor.
Frequently Asked Questions
Are There Any Potential Side Effects Associated with OmniBreathe?
Yes, they’re possible, even though the brand’s pages say otherwise. NAC can cause stomach upset, nausea, and rash, and MSK also lists asthma attacks and severe allergic reactions among other possible side effects, while bromelain can cause stomach upset and diarrhea. Stop taking it if you react badly, and call 911 if you have trouble breathing or swelling.
Does OmniBreathe Cleanse the Lungs?
I found nothing showing that it does. Your lungs clear themselves through mucus and coughing, and NAC may help some people thin mucus, but no study I found shows this capsule removing tar or toxins.
How Soon Might You Notice Effects From OmniBreathe?
The brand says 24-72 hours, with fuller effects after 2-4 weeks, and some buyers it quotes report a few days. That’s marketing and personal reports, so don’t judge your lungs by it. See a doctor if your breathing isn’t improving.
Can You Take OmniBreathe With Inhalers Or Other Medicine?
Ask your doctor first. Its FAQ says it’s safe with most medications and also tells you to consult your doctor. The ingredients have listed interactions, including with nitroglycerin and blood thinners.
Did The FDA Check OmniBreathe Before It Went On Sale?
No, the FDA doesn’t review supplements that way before they’re sold. A registered facility is about where it’s made, not whether the product works.
Final Verdict: Should You Buy It?
Yes, if you’re a healthy adult who wants a low-cost NAC-based supplement and you treat it as an experiment. It’s easy to take and the daily price is low, but I found no trial on the product, and nothing I read backs the three-day cleanse. I gave it 8.0 out of 10 for the low daily price, the easy routine and the NAC in it; the missing trial, the unclear refund terms and the safety questions are why it isn’t higher. If you have asthma or COPD, or you’re still smoking, your doctor and proven treatments come first.
