1. Serving size
Amounts on the panel are per serving. Check how many capsules make a serving, and follow the directions on your bottle.
2. Amounts for each ingredient
Named ingredients with amounts let you compare with research. The seller’s page does not publish an ingredient list, so the panel on your bottle is where to look.
3. Check the other ingredients
Look at the capsule shell, fillers and allergens under Other Ingredients.
4. Check the claims
Be wary of any lung supplement that promises to repair lungs, clear damage or replace medication, or is described as “FDA approved.” Supplements are not FDA-approved products and cannot claim to treat respiratory disease.
5. Check interactions
If you take prescription medication, ask a healthcare professional first.
6. Warnings and who should avoid it
Look for pregnancy and nursing statements, age limits and conditions listed.
