Patient discussion about oil
Q. Does fish-oil helps exercise induced asthma? I was diagnosed with exercise induced asthma a couple of year ago, and since then had better and worse times with my asthma, although the treatment I get. I read in a newspaper that fish oil can help exercise induced asthma- is that true? Do I have to eat fish-oil specifically or can I eat fish instead (I really, really, hate fish-oil…)?
A. I take 6, 1000mg softgels/day. It helps my asthma, arthritis and has lowered my closterol. Started with 10 and worked down to 6, which seems to work best, though sometimes I need the extra.
