BreathiZen in 60 seconds
BreathiZen is a once-daily oral spray for adults who want to support clear breathing. Four pumps, 0.60 mL, taken in the morning. It carries ten named botanicals, led by mullein leaf and bromelain. The seller does not publish how much of any ingredient is in a serving, so no one can compare it with the doses used in research. Packs cost $89, $179 and $294, which works out at $0.89 to $0.49 a day, with a 60-day money-back guarantee and US shipping.
That is the whole product in one paragraph. The rest of this page explains each part of it, including the parts that do not flatter the product.
Buy the single bottle first if you have never used a lung spray.
Sixty days is long enough to judge one bottle fairly. It is not long enough to judge six. We would rather tell you that than sell you the bigger pack.
Why people look for a lung supplement like BreathiZen
Most people who go looking for a breathing supplement are not sick. They are tired of noticing their own breathing.
It shows up in small ways. A flight of stairs that used to be nothing. A cough that hangs around for a fortnight after a cold. Waking up with a throat that feels like sandpaper in the heating season. A run that ends earlier than it did two winters ago. None of that sends you to a doctor. All of it sits in the back of your mind.
Air quality is part of it. So is age: lung function peaks in the mid-twenties and drifts down slowly after that in everybody. So is the simple fact that most of us spend the day indoors and shallow-breathe through it.
Supplements do not fix any of that. What a product in this category offers is narrower: a small daily habit built around ingredients traditionally used for the airway, plus, in this case, a couple with real human research behind them. Whether that is worth $0.49 a day is a question you can only answer for yourself, and we would rather help you answer it than talk you into it.
What this is not
BreathiZen is a dietary supplement. It is not a treatment for asthma, COPD or any other lung condition, it is not a rescue inhaler, and it is not a substitute for anything your clinician has prescribed. If you are short of breath in a way that worries you, that is a conversation for a doctor, not a spray.
What is BreathiZen?

BreathiZen is a liquid dietary supplement in a 2 fl oz (60 mL) amber glass bottle. You shake it, spray four pumps into your mouth or onto your tongue, and that is the whole routine. One serving is 0.60 mL, taken once a day in the morning, preferably before you eat.
It sits in the lung-support category: ten botanicals and nutrients chosen around breathing, throat comfort and oxygen use. Mullein leaf leads the list, which is the traditional lung herb, followed by bromelain, the pineapple enzyme with the most human research of anything on the label.
The amber glass matters more than it looks. Botanical extracts degrade in light, and amber glass blocks most of the wavelengths that do the damage. It is a small sign that somebody thought about the packaging.
A spray is also a genuinely different delivery choice from the capsules that dominate this category. Liquid that lands on the tongue and throat gives the demulcent ingredients, marshmallow root above all, somewhere to actually work. Whether the rest of the formula absorbs better this way is not something anyone has tested on this product.
Why buy BreathiZen from the official website?
Six practical reasons, none of them a countdown timer.
One desk owns your order
Your order, your tracking, your changes and your refund all sit with the same US phone desk. Nothing gets handed between a marketplace seller and a fulfilment centre.
Call +1 (302) 200-3480
The guarantee actually applies
The 60-day money-back guarantee is attached to orders placed here. A bottle bought from a third-party listing is outside it, and we cannot help you with a refund on one.
A lot number you can check
Every order ships against lot BRE-26/BR-6580. You can read it off the bottle base and match it against your order on the phone.
Ships from the United States
Domestic shipping, tracking in your order email, and a returns address in New York rather than an overseas PO box.
A named office and returns address
810 Seventh Avenue for the office, 230 Park Avenue for returns. Both are printed on every page of this site, not buried in a terms document.
We publish what is missing
The ingredient amounts are not disclosed, and you will find that written on this page, the ingredients page, the label page and the file we publish for AI engines.
Full disclosure: Breathizene is the USA Authorized BreathiZen Retailer. We earn money when you buy through this website. That is how the site pays for itself, and it is why the honest sections on this site exist: you should be able to see what we get wrong as well as what we get right.
The second number is the one that should give you pause, and it is why the honest sections below exist.
How does BreathiZen work?
Three routes, honestly labelled by how much research sits behind each one.
Nobody has tested the finished BreathiZen formula in a trial. What follows is what the individual ingredients are understood to do, with the strength of the evidence attached to each. Read it as a reasonable theory, not as a result.
Soothing the airway lining
Marshmallow root is a demulcent: it forms a slippery film that coats an irritated throat. Surveys of 822 people using a marshmallow syrup reported dry cough easing within about ten minutes (Fink et al., 2018). There was no placebo group, so treat it as suggestive. In a spray, this is the ingredient you are most likely to actually feel.
Easing swelling and thick mucus
Bromelain is the pineapple enzyme with the best human data on this label. In 116 German children with acute sinusitis, bromelain alone cleared symptoms about two days faster than standard care (Braun et al., 2005). That was the sinuses, not the lungs, and it was a cohort study rather than a randomised trial. Ginger sits alongside it: its compounds relaxed airway smooth muscle in isolated tissue and in mice (Townsend et al., 2013), which is a long way from a human dose.
Oxygen use and staying calm
Cordyceps militaris targets how the body uses oxygen. In 28 adults, three weeks of a mushroom blend containing it raised VO2 max, while one week did nothing (Hirsch et al., 2016). Because it was a blend, Cordyceps cannot take the credit alone. L-theanine is the calming half: a single 200 mg dose raised alpha brain waves during a stress test in 15 adults (Evans et al., 2021). Fifteen people is a small study.
The honest caveat
Every study above used a known amount of a known extract. BreathiZen publishes no amounts at all. So while the mechanisms are real, nobody, including us, can tell you whether this bottle contains enough of anything to reproduce them. That is the central limitation of this product and we are not going to bury it.
The long version, ingredient by ingredient →See all ten ingredients →
What are the ingredients in BreathiZen?
Ten named ingredients. Every amount reads "not published", because none is.










Four of the ten have human research behind them: bromelain, marshmallow root, Cordyceps militaris and L-theanine. Three rest on laboratory or animal work: mullein, ginger and corydalis. Green tea has a large human survey but not a trial, and lemon carries vitamin C, which the Cochrane review found does not prevent colds (Hemilä et al., 2013).
BreathiZen dosage vs. research dosage: an honest look
This is the table most product websites leave out. Here is why it matters.
When a study finds an ingredient does something, it finds it at a specific dose. Bromelain trials use defined enzyme activity units. The theanine study used 200 mg. The Cordyceps study used a measured blend. Without an amount on the label, you cannot line this product up against any of them.
| Ingredient | Amount on the BreathiZen label | Amount in the research | Comparable? |
|---|---|---|---|
| Bromelain powder | Not published | Defined enzyme units in the sinusitis cohort | No |
| Marshmallow root | Not published | A syrup dose taken as needed | No |
| Cordyceps militaris | Not published | 4 g a day of a mushroom blend, three weeks | No |
| L-theanine | Not published | 200 mg, single dose | No |
| Green tea extract | Not published | Two cups of brewed tea a day, not an extract | No |
| Mullein leaf | Not published | No human trial exists | No trial |
| Ginger root | Not published | Isolated tissue and mice only | No trial |
| California poppy | Not published | Inside a three-part blend | No |
| Corydalis root | Not published | Mice and cell tests only | No trial |
| Organic lemon | Not published | Vitamin C at 200 mg or more a day | No |
One column of that table is the entire problem. If the seller publishes a Supplement Facts panel, this page will be updated the same week and the updated date at the top will move forward.
What this does not mean: it does not mean the bottle is empty, and it does not mean the ingredients are not in there. Plenty of reputable products use proprietary blends. It means that you are being asked to take the amounts on trust, and you should know that is what you are doing.
BreathiZen Supplement Facts: what the bottle prints
Ingredients named by the seller: Mullein Leaf Extract, Bromelain Powder, Marshmallow Root, Cordyceps Militaris, Ginger Root Extract, Green Tea Extract, L-Theanine, California Poppy Seed, Corydalis Root, Organic Lemon Extract.
Amount of each: not published. No Supplement Facts panel was supplied to us, and none appears on the artwork we were given.
Directions: Shake well. Spray 4 pumps (0.60 mL) into the mouth or onto the tongue once daily in the morning, preferably before the first meal.
Every line above was read from the bottle artwork supplied to this website. Where the seller's written brief disagreed with the label, we followed the label. See the full Supplement Facts page.
No Supplement Facts panel image was supplied to this website, so we have not published one. What you see above is the printed label text, read off the bottle artwork and reproduced without additions. If you receive a bottle with a panel on the back, photograph it and send it to [email protected] and we will publish it.
What are the benefits of BreathiZen?
Only the three claims printed on the label, plus what the label does not say.
Supports clear breathing
The label's first claim. Mullein, bromelain and ginger are the ingredients behind it. Bromelain has the human sinus data; mullein and ginger have tradition and lab work.
Printed on the label
Natural lung support
The second claim. Cordyceps militaris is the oxygen-use ingredient, and green tea brings the antioxidant polyphenols. Neither has been tested in this formula.
Printed on the label
Fast-acting spray
The third claim, and it is about delivery, not speed of results. Liquid on the tongue does not have to dissolve the way a capsule does. The demulcent effect of marshmallow root is the only part likely to feel immediate.
Printed on the label
What BreathiZen does not do
- It does not treat, cure or prevent asthma, COPD, bronchitis or any other lung condition. No supplement does, and the label does not claim it.
- It does not work as a rescue medicine. Nothing here opens an airway in an emergency.
- It does not repair lung damage. There is no ingredient on this label with evidence for that, and anyone telling you otherwise is selling something.
- It does not replace stopping smoking, which remains the single biggest thing anyone can do for their lungs.
- It does not promise you a result at any point in time. The reviews on this site include four-star ones that say week one felt like nothing.
BreathiZen pros and cons
What is good about it
- Ten named botanicals, not a two-ingredient formula with a big price tag.
- Four ingredients have real human research: bromelain, marshmallow root, Cordyceps and L-theanine.
- A spray is a sensible format for the demulcent ingredients.
- Amber glass protects botanical extracts from light.
- One serving a day is easy to actually keep doing.
- 60-day money-back guarantee, a US phone desk and a named returns address.
- $0.49 to $0.89 a day, which is ordinary for this category.
- A published lot number you can match against your order.
What is not
- No Supplement Facts panel. Not one amount is published. This is the big one.
- Corydalis root is a pain herb with no respiratory research at all. It is the weakest ingredient on the label.
- California poppy has never been tested on its own, and never for sleep.
- Mullein, the headline lung herb, has no human breathing trial behind it.
- Green tea extract carries caffeine in an unpublished amount.
- The finished product has never been tested in a trial.
- No third-party test report was supplied, only a CoA number.
- Six bottles is roughly 600 days of product against a 60-day guarantee.
Who is BreathiZen for?

It may suit you if
- You are an adult who notices your breathing more than you used to, and nothing is medically wrong.
- You want a once-a-day habit rather than three capsules at three different times.
- Winter air, city air or a dry heated office leaves your throat raw.
- You already accept that a supplement is a small lever, not a big one.
- You would rather buy from a seller with a phone number than a marketplace listing.
It is not for you if
- You are under 18, pregnant or breastfeeding.
- You take a blood thinner. Bromelain and green tea both interact with them.
- You have surgery booked in the next two weeks.
- You want a published dose you can check against the research. It does not exist for this product.
- You are looking for something to replace an inhaler or a prescription. This is not that, and never will be.
How to take BreathiZen
Exactly as printed on the label, plus the practical notes the label leaves out.
Shake the bottle
Botanical extracts settle. A few seconds of shaking each morning is the difference between an even dose and a thin one followed by a thick one.
Spray four pumps
Four pumps is 0.60 mL. Aim into the mouth or onto the tongue. Count them out loud the first week; it is easy to lose track at half past six in the morning.
Hold it for a few seconds
The label does not tell you to, but the demulcent ingredients coat on contact. Letting it sit before you swallow costs nothing.
Take it before your first meal
The printed directions say morning, preferably before eating. Bromelain is a protein-digesting enzyme, and enzymes are generally taken away from food when the point is an effect in the body rather than on the meal.
Write down the date you started
This is the step nobody does and everybody should. Put the date on your phone. When you get to day 50 you will want to know whether anything changed, and memory is a terrible instrument for that.
One bottle, in numbers
At 0.60 mL a day, a 60 mL bottle holds about 100 daily servings. The label itself does not print a day count. That is arithmetic from the printed serving size, not a claim the seller makes.
What form does BreathiZen come in?
A liquid oral spray in a 2 fl oz (60 mL) amber glass bottle. One serving is four pumps, 0.60 mL, taken once a day.
There is one thing worth flagging. The bottle artwork we were given shows a dropper-style cap, while the label text reads Fast-Acting Spray and the printed directions describe pumps. We follow the printed label and the printed directions, because that is our rule when two sources disagree. Check the fitment on the bottle you receive, and call +1 (302) 200-3480 if it does not match.
| BreathiZen oral spray | A typical lung capsule | |
|---|---|---|
| Servings a day | One | Two to three |
| Contact with the throat | Direct. It lands where the demulcents work | None. It dissolves in the stomach |
| Swallowing | Nothing to swallow | Capsule shell |
| Dose accuracy | Depends on pump priming and shaking | Fixed per capsule |
| Travel | Liquid, so airport rules apply | Easier |
| Amount disclosure | Not published here | Varies by brand |
BreathiZen vs. other lung supplements
A comparison of formats and disclosure practice across the category, not a ranking of named competitors.
| BreathiZen | Mullein-only drops | Lung capsule blends | NAC capsules | |
|---|---|---|---|---|
| Format | Oral spray, 60 mL | Tincture dropper | Capsules | Capsules |
| Ingredients | 10 named | 1 | 6 to 12 typically | 1 |
| Amounts published | No | Usually yes | Often a blend total | Yes |
| Human research on the lead ingredient | Bromelain: moderate | Mullein: none | Varies | NAC: moderate to strong |
| Servings a day | 1 | 2 to 3 | 2 | 1 to 2 |
| Typical daily cost | $0.49 to $0.89 | $0.30 to $0.60 | $0.70 to $1.50 | $0.20 to $0.50 |
| Guarantee | 60 days | Varies | Varies | Varies |
The fair reading: BreathiZen is competitive on format, breadth and buying terms, and it is behind on disclosure. A single-ingredient NAC capsule tells you exactly what you are getting for less money. It also gives you one ingredient instead of ten, and no throat-coating effect at all. Which trade you prefer is a real question with no obviously right answer.
How much does BreathiZen cost?
Three packs. One price each. No struck-through price we cannot source, and no timer.

$89.00
a bottle
Total $89.00$0.89 a day
- One 60 mL bottle
- 60-day money-back guarantee
- Ships from the United States
- Tracking in your order email


$59.67
a bottle
Total $179.00$0.60 a day
- Three 60 mL bottles
- $59.67 a bottle, down from $89.00
- 60-day money-back guarantee

Three figures are published on the sales page: $89, $179 and $294. They divide cleanly across one, three and six bottles. The seller has not put in writing which figure belongs to which pack, and no regular price is published, so we show no struck-through price and no savings percentage. Check the pack and the total on the checkout page before you pay.
BreathiZen cost per day, and which pack to choose
| Pack | Total | A bottle | A day | Days of product | Inside the 60-day window? |
|---|---|---|---|---|---|
| 1 bottle | $89.00 | $89.00 | $0.89 | About 100 | Yes, comfortably |
| 3 bottles | $179.00 | $59.67 | $0.60 | About 300 | You will judge it on bottle one |
| 6 bottles | $294.00 | $49.00 | $0.49 | About 600 | Ten times longer than the window |
Which pack we would actually buy
The single bottle, if you have never taken a lung spray. It costs $30 more a bottle, and it lets you find out whether you like the taste, the routine and the effect while you are still inside the guarantee. If you already know you will keep taking it, the six-bottle pack is the cheapest per bottle by a wide margin and there is no reason not to take it.
What we would not do is buy 600 days of product to evaluate a 60-day question. The per-bottle saving is real; so is the risk of a cupboard full of something you stopped using in March.
Is BreathiZen safe? Side effects and interactions
No side-effect list was published for this product, so what follows is drawn from the known profile of the ingredients on the label. It is not a complete list, and it cannot be, because the amounts are unknown.
| Ingredient | What to watch for | Who should be careful |
|---|---|---|
| Bromelain | Stomach upset; it thins the blood | Anyone on warfarin, apixaban, clopidogrel or daily aspirin. Stop two weeks before surgery |
| Green tea extract | Caffeine; liver strain has been reported at high extract doses | Anyone caffeine-sensitive, or with a liver condition |
| Ginger root | Heartburn; mild blood-thinning | Anyone with reflux, or on a blood thinner |
| L-theanine and California poppy | Drowsiness | Anyone on a sedative, sleeping tablet or anti-anxiety medicine |
| Corydalis root | Sedation; safety data is thin | Anyone on opioid pain medicine or a sedative |
| Marshmallow root | It can slow absorption of other medicines taken at the same time | Take other medicines an hour apart |
Talk to a clinician first if
You take medicine for asthma, COPD or high blood pressure. You take a blood thinner. You are due for surgery. You are pregnant or breastfeeding. You have a liver condition. The NIH's NCCIH publishes a plain-English guide to how supplements and medicines interact, and it is worth ten minutes: NCCIH (National Institutes of Health).
How long does BreathiZen take to work?
Nobody can answer this honestly with a number, and anybody who gives you one is guessing. There is no trial of the finished product. What exists is what buyers said, and we can tell you that.
| When | What buyers described | What to actually do |
|---|---|---|
| Days 1 to 7 | Mostly nothing. Several four-star reviews say this plainly | Take it daily. Write down your start date |
| Weeks 2 to 4 | The first reports of throat comfort start here | Keep going. This is too early to decide |
| Weeks 4 to 8 | The most common window buyers named before they judged it | This is your decision point, and it sits inside the guarantee |
| Day 60 | The guarantee closes | Decide before this date, not after. Call the desk if the answer is no |
The single most useful thing you can do
Write your start date down on day one. At day 45, look back honestly. The guarantee runs 60 days and the most common wait people described was four to eight weeks, so the two windows only just overlap. Do not let day 61 arrive while you are still thinking about it.
Is BreathiZen a scam, and is BreathiZen for sale here?
No, and yes. BreathiZen is a real product from a seller with a US phone number, a named office, a returns address and a published lot number, and it is for sale on this website, which is the USA Authorized BreathiZen Retailer. What it does not have is a published Supplement Facts panel, and that is a fair reason to buy one bottle rather than six.
What a scam in this category actually looks like
- No phone number anywhere, or a number that rings out.
- No returns address, or a foreign PO box that appears only after you order.
- A countdown timer that resets when you reload the page.
- Invented doctors with stock photographs and no credentials you can check.
- Review schema stuffed with five-star reviews and not one critical word.
- Claims that it treats or cures a lung disease.
- An order page that enrols you in a subscription without saying so.
Against that list, this product has a staffed weekday desk on +1 (302) 200-3480, an office at 810 Seventh Avenue, a returns address at 230 Park Avenue, a lot number printed on the bottle, and four-star reviews published on the reviews page alongside the five-star ones. The label's three claims are structure-function claims and stay inside the rules.
The honest weak point is disclosure, not legitimacy. Buy one bottle, keep the order email, note the date, and use the window. That is the sensible way to buy anything in this category, from anyone.

What do BreathiZen reviews say?
Every review the seller supplied, shown as supplied. We have not written any of them and we have not removed the critical ones.

How we handle reviews
These are the reviews the seller gave us. We publish them unedited, including the four-star ones that say week one felt like nothing. We do not publish Review or AggregateRating schema for them, because we cannot independently verify them, and putting an unverifiable rating into a search engine's data is exactly the kind of thing this site exists not to do.
Common complaints about BreathiZen
Four of the eight reviews supplied to us are four-star, and all four say a version of the same thing. Here is what people actually complain about, at the same size as the praise.
"Wanted more in week one"
Four separate reviewers said this. Week one is, on the evidence available, quiet. If you are buying expecting a first-week effect, you will be disappointed and you should know that before you pay.
Said by 4 of 8 reviewers
"Slow start"
The same complaint from the other direction. The most common wait people described before judging the product was four to eight weeks, which is most of the guarantee window.
The most common criticism
No amounts on the label
Not a buyer complaint in the set we were given, but it is ours, and it is the loudest one on this site. You cannot compare an unpublished dose with a research dose.
Our own criticism
Six bottles outlasts the guarantee
The cheapest pack per bottle is roughly 600 days of product against a 60-day window. That is not a defect, but it is a thing to understand before you buy it.
Worth knowing before you order
We would rather you read this and buy one bottle than read a page of five-star quotes and buy six.
Does BreathiZen have a money-back guarantee?
Yes. BreathiZen orders placed on this website carry a 60-day money-back guarantee, as published on the sales page. To start a return, call the order desk on +1 (302) 200-3480 with your order ID, then post the bottles to 230 Park Avenue, Floor 10, New York, NY 10169, USA with your full name, email and order ID inside. You pay the return postage. The desk credits the refund in about 3 to 5 business days once the return is processed, and your bank takes roughly another 5 to 10 days to show it.
Call the desk
Ring +1 (302) 200-3480 with your order ID to hand. Monday to Friday, 9:00am to 5:00pm Eastern.
Pack the bottles
Put your full name, the email you ordered with and your order ID in the box. Without those three things the desk cannot match the return to your payment.
Post it with tracking
Send it to 230 Park Avenue, Floor 10, New York, NY 10169, USA. You pay the postage, and you should use a tracked service so you can prove it arrived.
Wait for the two clocks
About 3 to 5 business days at the desk once they process it, then roughly 5 to 10 days at your bank.
Our editorial score for BreathiZen
Ten named botanicals, and four of them have real human research behind them. Two have nothing to do with breathing.
No Supplement Facts panel was published to us. Not one amount is disclosed. This is the biggest problem with the product.
Bromelain, marshmallow root, Cordyceps and L-theanine have human data. Mullein, ginger and Corydalis do not.
$0.49 to $0.89 a day depending on the pack. That is ordinary for a ten-botanical formula, and cheap next to a daily coffee.
A 60-day window, a real US phone number, a named returns address and US shipping.
The three printed claims are structure-function claims and stay inside the rules. No disease claims appear on the artwork.
A published lot number, a staffed weekday desk and a returns address you can post to.
A 6.4 is a middling score and it is meant to be. The product is competently built, reasonably priced and sold on fair terms. It loses most of its points in one place: you cannot see the amounts, so you cannot check the formula against the research. If a Supplement Facts panel is published, this score goes up and the date at the top of this page moves forward the same week.
Who publishes this BreathiZen website?

This website is published by Breathizene, the USA Authorized BreathiZen Retailer. Pages are written and reviewed by the BreathiZen Editorial Desk. We do not invent a doctor's name to put at the top of a page, and you will not find a stock photograph of one anywhere on this site.
Our method is short enough to print here. The label is the source of truth. Where the seller's written brief disagrees with the label, the label wins and we say so. Anything the seller has not published is written as "not published", never guessed. Every study we cite is one we opened. When we correct something, the updated date moves forward.
We earn money when you buy through this site. That is why the dose table, the pros and cons, the complaints section and the editorial score exist: a site that only tells you good things is not worth reading.

BreathiZen FAQ: frequently asked questions
What is BreathiZen?
BreathiZen is a dietary supplement sold as a liquid oral spray in a 2 fl oz (60 mL) amber glass bottle. The label prints three claims: Supports Clear Breathing, Natural Lung Support and Fast-Acting Spray. It holds ten named botanical and nutrient ingredients. It is not a medicine and it is not a rescue inhaler.
How much of each ingredient is in it?
Not published. No Supplement Facts panel was supplied to us and none appears on the artwork we were given. That means nobody outside the company can compare these amounts with the amounts used in research. It is the single biggest gap in the product and we say so on every page that touches ingredients.
How do I take BreathiZen?
Shake the bottle well. Spray 4 pumps, which is 0.60 mL, into your mouth or onto your tongue. Take it once a day in the morning, ideally before your first meal.
How long does BreathiZen take to work?
Nobody can promise you a timeline and we will not try. The buyers who left reviews most often described waiting four to eight weeks. Several said week one felt like nothing. If you want to judge it fairly, judge it at the end of the guarantee window.
How much does BreathiZen cost?
Three figures are published: $89, $179 and $294. They work out at $89.00, $59.67 and $49.00 a bottle across one, three and six bottles. Confirm the pack and the total on the checkout page before you pay.
Which pack should I buy?
If you have never used a lung spray, buy one bottle. You can judge the product and still be inside the 60-day window. The six-bottle pack is the cheapest per bottle, but six bottles is about 600 days of product and the guarantee runs for 60.
Can I take it with my medication?
Ask a clinician first, and take the bottle with you. Bromelain and green tea can both add to a blood thinner. Anything calming can add to a sedative. The NIH's NCCIH publishes a plain guide to supplement and medicine interactions, and we link to it.
What is the money-back guarantee?
60 days, as published on the sales page. Call the order desk on +1 (302) 200-3480 with your order ID to start a return.
Ready to try BreathiZen?
One bottle, one serving a day, sixty days to change your mind. We would rather you started small and stayed than bought six and stopped in March.
