I was bedridden for 2 years with asthma, and chronic bronchitis. I started Protandim for another issue but it is over 2 yrs now and I don't even need an inhaler.  I was on 4 nebulizers and 2 inhaler a day. I got up to get to the bathroom which was extremely close and it was difficult.  I thought it was just a matter of time for the oxygen tank. No I don't smoke, and I was 51 at the time.
