Yes this was my thinking too; if I have deficiencies at least I can now try to correct them re my test results. It's not a cure and I certainly wasn't expecting one from taking supplements but at least I can continure to work on it without thinking I'm just blowing in the wind. I went to see a virologist to get my immune panel done and when I mentioned how sick my gut was he tested me for h.pylori and I was positive so he treated me for this and my gut problems went away after so many years of feeling sick. So sometimes we can find things just by mentioning them because we have so many other things going on- it makes their heads spin lol. My doctor wanted me be tested by Enterolab in the US for gluten sensitivities but I decided to try the gluten free diet instead of paying for the test. The gluten free diet was actually easier than I thought it would be because there are so many alternatives in healthfood stores now. I didn't feel any better after one year but my digestion did improve. I think we have to heal our gut in order to move on so I think you should try this and see. I am familiar with Rich's protocol and I brought it to my doctor to look it over since he is into this stuff. I take folonic acid and methyl B12 with a few other things but the one thing that helped me in a noticeable way was Magnesium injections 3x/week and fish oils.
