BreathiZen Reviews and Complaints: Company Publish New Guide on Oral Spray Supplement Ingredients

BreathiZen spray reference guide compares the Supplement Facts panel with federal ingredient data and sets out refund terms in plain language

LAKELAND, Fla. — October 27, 2026 — GEX Corp, the U.S. distributor of BreathiZen, today released a consumer label guide for its oral herbal spray and announced that customers who receive a bottle with a pump that does not dispense can request a replacement or a refund. The guide lists each ingredient on the BreathiZen Supplement Facts panel alongside what federal health agencies report about it, and it identifies where that record is limited.

The announcement follows a sharp rise in public attention to the product. Google Trends data shows worldwide search interest in BreathiZen over the past three months up more than 5,000 percent compared with the preceding three months, and by the same margin compared with the same period a year earlier, a level the tool labels “Breakout.” The leading related searches include “breathizen reviews,” “breathizen reviews and complaints,” “breathizen spray” and “breathizen spray reviews.”

Many of those searches lead to BreathiZen reviews and complaints posted on Trustpilot in September and October 2026. Reviewers there described spray pumps that clogged after a few uses and ingredient lists online that did not match the bottle. The guide and the pump policy are GEX Corp’s response to both issues.

“People are typing ‘complaints’ into the search bar because they have seen conflicting information, and some of it did not come from us,” said Niel Browers, Product Head at GEX Corp. “The most useful thing we can do is point to the label on the bottle, explain what the research on each ingredient does and does not show, and fix the pump problem for anyone who has it.”

The Pump Replacement Policy

The most frequent complaint in recent BreathiZen spray reviews concerns the dispenser rather than the liquid inside it. Reviewers described residue forming around the nozzle, bottles that would not spray even after shaking, and difficulty reaching support. A smaller number of reviews were positive, and several reviewers said it was too early to judge.

Under the policy announced today, customers whose bottle does not spray can email contact@customercs.com, the support address printed on the label, to request a replacement bottle or a refund. GEX Corp asks that the email include the customer’s name, the email address used for the order and, if available, the order number, along with a short description of the problem.

The label directs users to shake the bottle well before each use. GEX Corp advises against moving the liquid into another container, which some reviewers reported doing. The label’s dosing directions are based on the metered pump, and its storage directions apply to the original sealed bottle.

“A spray that doesn’t spray is a defect, not a matter of opinion,” Browers said. “Anyone who has one should write to us, and we’ll make it right with a replacement or a refund.”

What BreathiZen Spray Is

BreathiZen is a liquid dietary supplement taken by mouth. It is not an inhaler, a nasal spray or a topical rub, and it is not meant to be breathed in. Each 2-fluid-ounce (60 mL) bottle holds 100 servings. The label directions call for four pumps, about 0.60 mL, sprayed directly into the mouth or onto the tongue once a day. The brand’s FAQ suggests using it in the morning before the first meal. The label states the product is made in the USA with globally sourced ingredients.

Because BreathiZen is sold as a dietary supplement, it falls under a different regulatory framework from drugs. The U.S. Food and Drug Administration does not review or approve dietary supplements before they are sold, and supplement labels may not claim to diagnose, treat, cure or prevent any disease.

The front of the bottle carries three general wellness statements about breathing, respiratory wellness and lung function. Each is marked with an asterisk that links it to the FDA disclaimer printed on the side panel. Under federal rules these are known as structure/function statements. They describe a general role in the body and are not claims that the product treats or prevents a condition, and the FDA does not evaluate them before they appear on a label.

What the Label Lists

The BreathiZen Supplement Facts panel groups its botanicals under a single heading, “Proprietary Blend,” with a combined weight of 154 mg per four-spray serving. Three ingredients are listed, in this order: mullein (Verbascum thapsus) leaf extract 10:1, ginger (Zingiber officinale) root extract and organic lemon (Citrus limon) extract. The panel marks the blend “Daily Value not established,” the standard notation for ingredients that have no federal reference intake.

Earlier materials described the formula differently. A September 2026 product announcement listed five ingredients, two of which do not appear on the current panel. The guide states that the Supplement Facts panel on the bottle is the authoritative record of what a serving contains. Any web page, review site or advertisement that names other ingredients should be checked against the bottle, and readers who find a mismatch can report it to the support address on the label.

How to Read a Proprietary Blend

A proprietary blend lets a company list several ingredients under one combined weight without stating how much of each is present. Federal labeling rules require only that the ingredients appear in descending order by weight. On the BreathiZen panel, that means the serving contains more mullein extract than ginger extract and more ginger extract than lemon extract, but the label does not say by how much.

That matters when comparing the product with published research. Most human studies test a single ingredient at a stated dose, often measured in hundreds of milligrams or more. Because all three BreathiZen botanicals share 154 mg, no one of them can be present at more than that amount, and each is likely present at considerably less. The guide therefore does not compare label amounts with study doses, and it repeats that limitation in each ingredient section.

The “10:1” figure next to mullein describes the extract’s concentration. It means one part of finished extract corresponds to roughly ten parts of dried leaf used to make it. The ratio describes how the extract was produced. It does not mean the serving delivers ten times the effect of the leaf, and it does not indicate which plant compounds were retained.

What the Other Ingredients Do

The “Other Ingredients” line lists the liquid that carries the blend. Purified water is the base. Glycerin, a clear, slightly sweet liquid used widely in foods and oral liquids, adds body and helps keep the botanical extracts in solution. Citric acid, the acid found naturally in citrus fruit, adjusts acidity and taste. Potassium sorbate and sodium benzoate are preservatives that limit the growth of mold and yeast in water-based products once a bottle has been opened.

All four of those ingredients appear on FDA lists of substances generally recognized as safe for use in food. The label also lists “natural flavors” without naming them, which federal labeling rules permit. People with known sensitivities to any of these ingredients can ask the distributor what the flavor component contains before use.

The side panel adds three standard instructions: keep the bottle out of the reach of children, do not use it if the safety seal is damaged or missing, and store it in a cool, dry place away from heat, light and humidity.

Mullein Leaf Extract: What the Record Shows

Mullein is a tall biennial plant with soft, grey-green leaves and a long history in European, Asian and North American folk practice, much of it connected with the throat and chest.

Neither the NIH Office of Dietary Supplements nor the National Center for Complementary and Integrative Health (NCCIH) publishes a safety page on mullein. The most formal assessment comes from Europe. In 2018, the European Medicines Agency’s Committee on Herbal Medicinal Products concluded that mullein flower preparations may be used for relief of sore throat associated with dry cough and cold, on the basis of long-standing traditional use. The committee also noted that clinical studies were lacking. That assessment concerns the flower, while BreathiZen uses an extract of the leaf.

A 2022 review of Verbascum thapsus published in Phytotherapy Research catalogued the plant’s flavonoids, saponins and other constituents and summarized the research on them. Most of that work was carried out in laboratories or in animals rather than in people. Earlier reviews reached a similar conclusion: the traditional record is extensive, and controlled human trials are scarce. None of that research tested BreathiZen.

Ginger Root Extract: Federal Safety Findings

Ginger is the most thoroughly studied ingredient on the BreathiZen panel. It comes from the rhizome of the plant behind the familiar kitchen spice.

NCCIH’s “Ginger: Usefulness and Safety” page reports that ginger taken by mouth as a supplement has a long record of safe use in studies. It lists heartburn, abdominal discomfort, diarrhea and irritation of the mouth or throat among possible side effects. NCCIH describes ginger supplements as possibly safe during pregnancy but asks pregnant women to discuss them with a health care provider first, and it notes that little is known about ginger during breastfeeding. People taking any medication are advised to check with a provider before taking ginger or other herbs, because some herbs interact with medicines.

LiverTox, the NIH database on the liver safety of drugs and supplements, places ginger in its lowest-concern category and describes it as an unlikely cause of clinically apparent liver injury. It reports that adverse effects are uncommon and usually mild and digestive.

Most human ginger research uses doses measured in hundreds of milligrams to grams, usually in capsule form, and often looks at nausea. Because ginger shares a 154 mg blend with two other botanicals in BreathiZen, those study doses cannot be matched to a serving of the spray.

Organic Lemon Extract: A Familiar Food Ingredient

Lemon is among the most widely eaten citrus fruits in the world, and lemon extracts are common flavorings in foods and drinks. Published reviews of Citrus limon describe flavonoids and other phenolic compounds in lemon-derived materials, with the composition varying by the part of the fruit used and the extraction method.

No federal agency publishes a supplement safety page on lemon extract. The BreathiZen panel does not list a vitamin C amount, so the lemon extract in this product should not be read as a measured source of vitamin C.

What the Guide Does Not Claim

Every study cited in the guide examined a single ingredient, usually in a different form, dose or population from a four-spray oral serving. A trial of ginger capsules does not show what a blended liquid containing ginger will do.

GEX Corp has not published clinical research on the finished spray. The guide makes no claim about what BreathiZen does for breathing, lung function or any respiratory condition, and no source it cites mentions or endorses the product.

Who Should Talk to a Clinician First

The BreathiZen caution panel asks pregnant or nursing women, anyone under 18 and anyone with a known medical condition to consult a physician before use, and not to exceed the recommended amount. NCCIH’s ginger guidance adds anyone taking medication.

The NIH Office of Dietary Supplements advises telling every health care provider about any supplement in use. It specifically recommends doing so before surgery, because some products can affect bleeding or anesthesia.

Shortness of breath, a cough that lasts for weeks, wheezing, chest pain or reduced tolerance for exercise can have many causes, some of them serious. These symptoms call for evaluation by a health care professional rather than a dietary supplement. People who already use inhalers or other prescribed treatment for asthma or COPD should not stop or change that treatment without speaking to their clinician.
