I tried D-limonene but it didn't help me - possibly aggravated my gastritis. The only natural supplement that has helped me at all so far is milk thistle (though not sure why). I've tried an awful lot of things but have worked out only very recently that things in tablet form aggravate my gastritis - capsules are OK.
