Anyone else have a weak immune system?

I got a couple of blood tests just to check if my hair loss is caused by something else and all that came up is that I have very low immunoglobulin A (IgA). I’m very sensitive to gluten and dairy which is apparently linked to low IgA.

Has anyone else got this? Or successfully improved their IgA?

I know there are a lot of suggestions on the web; but there are not many success stories that I have read and I don’t want to spend money on useless vitamins.

At the moment I’ve started taking glutamine; lots of bodybuilders reckon this has improved their immune system.

My immunity used to be terrible when I was an insomniac. I didn't really place why I was getting sick to lack of sleep until I started to cram for a couple of my classes. After a night or two a cramming I would get sick. I finally put 1 and 1 together and started to force myself to get good sleep. I plus added the two best immunity foods: oranges and sardines. I haven't had an type of illness in two years.
