BreathiZen names all seven of its ingredients, which makes it easy to check against your own health. Here is the short version.
BreathiZen is generally well tolerated, but check with your doctor first if you take blood thinners (bromelain, ginger and cordyceps), are caffeine-sensitive or have a heart-rhythm concern (green tea), have a pineapple allergy, are pregnant or breastfeeding, or are treated for any breathing condition. It never replaces an inhaler.
The four BreathiZen ingredients with a note
- Bromelain — may add to blood thinners; avoid with pineapple allergy.
- Ginger — may add to blood thinners in larger amounts.
- Green tea — natural caffeine; rare liver reports with concentrated extracts.
- Cordyceps — check if you take blood thinners, diabetes or immune-suppressing medicine.

Buy nowBreathiZen and diagnosed breathing conditions
BreathiZen does not treat asthma, COPD, bronchitis or any diagnosed condition and is never a substitute for a rescue inhaler. Keep everything prescribed exactly as directed. If your breathing is getting worse, that is an appointment, not a purchase — see when breathing trouble needs a doctor.
When to stop BreathiZen
Stop and get help for swelling, a rash, unusual bleeding, a racing heart, yellowing skin or eyes, or any breathing difficulty.
