Quick answer: Look for a full ingredient list with amounts, realistic claims, clear warnings and clear refund terms. Avoid any product that promises to repair or detox the lungs.
1. A full ingredient list
Every active ingredient and its amount should be visible on the label.
2. Realistic claims
Wording such as “supports breathing comfort” is a structure and function statement. Claims to treat or reverse lung disease are a red flag.
3. Clear warnings
Look for pregnancy, nursing, age and medication statements.
4. Clear refund terms
Check how long the guarantee lasts, what you must send back and who pays shipping.
5. Your own health situation
If you have asthma, COPD or any lung condition, do not use a supplement in place of prescribed care. See Healthy Habits for Lung Health.
