works for me
I have been using this on and off for about six years, when my doctor told me to start using Bromelain and Magnesium after I survived a house fire which did severe damage to my lungs (and cardio system).  If I go for a few weeks (months) without this, I start to notice the strain on my lungs and heart again.  Using this, within a week or two, good again.<br /><br />Sadly, this is a very difficult product to find, rarely available on Amazon or other resellers.
