Quick answer
This guide compares seven lung support supplements by format, available label information, advertised price and refund terms. None is a proven lung detox treatment, and these products do not replace quitting smoking or medical care. Start with label transparency, safety and your budget rather than marketing promises.
These desk-based comparisons use available product information and ingredient research. We have not lab-tested the products or established that any finished formula improves lung health. Full labels and doses are not available for every product; those gaps limit our assessment. We do not assign numerical scores or rank clinical effectiveness.

1. Pulmo Balance: best capsule overall
Pulmo Balance is one of the more complete lung support capsules we have looked at. It pairs mullein, a traditional herb for the airways, with bromelain, maritime pine bark, stinging nettle, tiger milk mushroom and quercetin, plus BioPerine to help absorption. A 90-day refund window is one of the longer ones in this category, which makes it a low-risk way to try a daily respiratory wellness routine.

|---|---|
| Form | Capsules |

| Price from | $49 per bottle (6-bottle bundle) |

2. RespiClear: best refund policy
RespiClear is a liquid lung support formula built around mullein leaf and cordyceps, with bromelain, ginger and lemon peel. A single dropper each morning makes it one of the easiest routines in this category, and its 180-day refund policy, with no need to send the bottles back, is the most generous guarantee we have seen on a lung supplement.
| RespiClear | |
|---|---|
| Form | Drops |
| Key ingredients | Mullein, cordyceps, bromelain, ginger, lemon peel |
| Price from | $49 per bottle (6-bottle bundle) |

3. Breathe: best traditional herbal drops
Breathe is a liquid herbal formula that reads like a classic cough-season tea in a dropper: mullein, manuka honey, thyme, ginger, peppermint and lemon peel. It publishes a Supplement Facts label, gives you 60 servings per bottle and is easy to take. Bundle pricing and a long refund window make it a comfortable product to try.
| Breathe | |
|---|---|
| Form | Drops (60 servings) |
| Key ingredients | Mullein, manuka honey, thyme, ginger, peppermint |
| Price from | $49 per bottle (6-bottle bundle) |
| Refund | 180 days advertised |
What we like
- Published Supplement Facts label
- Familiar, traditional ingredients with a long history of use
- Includes manuka honey, a well-loved throat soother
Keep in mind
- Proprietary blend, so individual amounts aren’t listed
- Shipping is added on one- and three-bottle orders
4. Lungora: most transparent label
Lungora stands out for something many lung supplements skip: a full Supplement Facts label with the exact amount of every ingredient. Its one-capsule-a-day formula combines glucosamine, ginkgo, turmeric, lutein, green tea and bamboo silica for antioxidant and circulation support. It’s simple to take, competitively priced in bundles and backed by a 60-day refund.
| Lungora | |
|---|---|
| Form | Capsules (1 a day) |
| Key ingredients | Glucosamine, ginkgo, turmeric, lutein, green tea |
| Price from | $49 per bottle (6-bottle bundle) |
| Refund | 60 days |
What we like
- Full Supplement Facts label with every dose listed
- Just one capsule a day
- Antioxidant-focused formula with well-known ingredients
Keep in mind
- Doesn’t include the traditional cough herbs, such as mullein, found in many lung formulas
- Glucosamine may not suit people with a shellfish allergy
5. BreathiZen: most convenient (oral spray)
BreathiZen is the only oral spray in our group, and that makes it one of the most convenient ways to take mullein. A concentrated 10:1 mullein leaf extract is paired with ginger and organic lemon, the label is published, and each bottle holds 100 servings. Five bonus items with bundles and a 60-day refund round out a friendly package.
| BreathiZen | |
|---|---|
| Form | Oral spray (100 servings) |
| Key ingredients | Mullein 10:1, ginger, lemon |
| Price from | $49 per bottle (6-bottle bundle) |
| Refund | 60 days |
What we like
- The only oral spray in our group, fast and easy to use on the go
- Concentrated 10:1 mullein extract
- Published Supplement Facts label
Keep in mind
- Fewer ingredients than multi-herb formulas
- Blend amounts aren’t broken down

6. Respilean: liquid drops with a 180-day return policy
Respilean is a liquid respiratory support formula in a 2 fl oz dropper bottle. Its research page points to a broad mix of ingredients, including cordyceps, mullein, bromelain, ginger, citrus peel, green tea and bacopa. The reference list is not a Supplement Facts panel, so the actual formula, ingredient amounts and serving size remain unverified. Ask the seller for the label before buying.
| Respilean | |
|---|---|
| Form | Drops |
| Key ingredients | Full formula and amounts unverified; research references are not a label |
| Price from | $49 / bottle (6-bottle bundle) |
| Refund | 180 days |
What we like
- Broad blend that goes beyond a single herb
- Includes cordyceps, one of the better-researched ingredients in this category
- Liquid format, easy to take or mix into a drink
Keep in mind
- We couldn’t confirm a full Supplement Facts panel from the official site at the time of writing
- Sold online only

7. Lung Expand Pro: best for clinically studied herbs
Lung Expand Pro is a one-tablet-a-day formula that brings together some of the best-studied European herbs for the chest, including pelargonium (umckaloabo) and ivy leaf, along with mullein, serratiopeptidase and vitamin D3. It publishes a full label, ships free in the US and comes with a 60-day refund. One ingredient, coltsfoot, deserves a quick safety check, which we explain below.
| Lung Expand Pro | |
|---|---|
| Form | Tablets (1 a day) |
| Key ingredients | Pelargonium, ivy leaf, mullein, vitamin D3 |
| Price from | $49 per bottle (6-bottle bundle) |
| Refund | 60 days |
What we like
- Includes pelargonium and ivy leaf, two of the better-studied herbs for chest comfort
- Full label with vitamin D3 dose listed
- One tablet a day
Keep in mind
- Contains coltsfoot, which may contain liver-harming alkaloids unless it’s certified free of them
- Herbal blend amounts aren’t broken down

How we choose and rate lung supplements
| What we rate | What we look for |
|---|---|
| Formula and ingredients | Ingredients with a traditional or research-backed role in respiratory wellness, at sensible amounts where they are disclosed |
| Ease of use | How simple the daily routine is: capsules, tablets, drops or spray |
| Value for money | Price per bottle and per serving across the available bundles |
| Refund policy | The length of the refund window and how easy it is to use |
| Buying experience | Clear pricing, contact details and a published returns process |
A product that doesn’t publish a full Supplement Facts panel doesn’t lose points for that alone, because many brands in this category only list key ingredients online. We do note it in each review so you can ask the company or check the bottle. Read our full editorial policy.
What lung supplements can and can’t do
Lung support supplements are best seen as one small part of a healthy routine. Many use herbs with a long traditional history, such as mullein, thyme and ginger, and a few ingredients, like pelargonium, ivy leaf and cordyceps, have been studied in clinical trials, though the evidence is mostly small and early.
What no supplement can do is treat, cure or reverse a lung disease, undo smoking damage or replace an inhaler or other prescribed treatment. The biggest gains for your lungs still come from quitting smoking, staying active, breathing exercises and a diet rich in fruit and vegetables. For more, read do lung detox supplements work?
How to choose the right one for you
- Prefer capsules? Start with Pulmo Balance or Lungora.
- Prefer liquids? RespiClear, Breathe and Respilean are all drops.
- Want the easiest routine? BreathiZen is a quick oral spray.
- Want the lowest-risk trial? RespiClear offers 180 days with no need to return the bottles.
- Want herbs with clinical studies? Lung Expand Pro includes pelargonium and ivy leaf, but read our note on coltsfoot.
- Take blood thinners? Talk to your doctor first, as several of these products contain bromelain, ginkgo, ginger or enzymes.
Safety basics
Most of the ingredients in these products are well tolerated by healthy adults, but supplements can still cause side effects and interact with medicines. Buy only from the official website, follow the label directions, and stop if you notice anything unusual. Watch out for red flags such as cure claims or fake FDA approval badges.
Talk to a doctor first
Supplements can interact with medicines and aren’t right for everyone. Talk to your doctor or pharmacist before starting any lung support supplement, especially if you have asthma, COPD or another lung condition, take regular medication, or are pregnant or breastfeeding.
Get help now
Call 911 or go to the nearest emergency room if you have severe shortness of breath, chest pain, blue or gray lips, coughing up blood, or confusion. A supplement is never a substitute for urgent care.
