1. Serving size
Amounts on the panel are per serving. For drops, check how many drops or how much liquid 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 names its ingredient without an amount, so the panel on your bottle is where to look.
3. Check the carrier
Tinctures often contain alcohol or glycerin. Check Other Ingredients if this matters to you.
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.
