The single most reliable thing you can do for easier stairs costs nothing: walk more. BreathiZen is designed to sit beside that habit.
The CDC recommends adults get at least 150 minutes of moderate activity (like brisk walking) or 75 minutes of vigorous activity (like running) each week, plus two days of muscle strengthening. Regular walking is the most reliable way to make stairs and hills feel easier; BreathiZen's cordyceps is there to support it, not replace it.
Why walking beats any bottle — BreathiZen included
Regular activity trains your heart, lungs and muscles to work together more efficiently. Over weeks, the same flight of stairs simply takes less out of you.
How much activity with BreathiZen
The CDC guideline is at least 150 minutes of moderate activity a week — or 75 minutes of vigorous activity — plus two days of muscle strengthening. One minute of vigorous activity counts roughly like two of moderate.

BreathiZen's cordyceps and your walks
Cordyceps militaris is an adaptogenic mushroom associated with stamina. It supports your walks; it does not stand in for them. If walking brings on chest pain or unusual breathlessness, stop and see a doctor.
