I have a slight asthma condition which during the winter months gets worse due to the house being closed up. During this time I use the Advair preventive medication which I would prefer not to use. I've taken this supplement and haven't noticed any improvement in my breathing or asthma condition. There is also a very sharp biting taste when taking the tablets.
