Two of BreathiZen's five botanicals focus on airway comfort. Here is where they come from and why they are paired.
Airway-comfort share of the BreathiZen formula
Two of the five botanicals support the body's normal mucus clearing.
Mullein in BreathiZen
Mullein is a tall, velvet-leaved plant used in traditional respiratory formulas. BreathiZen uses a 10:1 leaf extract. Read the WebMD overview.
Bromelain in BreathiZen
Bromelain is an enzyme from pineapple stems, used here at 2400 GDU/g. It supports the body's process of thinning mucus so it clears naturally. Read the NCCIH overview. People who take blood thinners should show the label to their doctor first.
Why BreathiZen Pairs Them
One supports normal clearing, the other supports the thinning that makes clearing easier. See the rest of the formula on the ingredients page.
