I've been taking Thorne - Betaine HCL (3 caps with main meals) for 2 years now. I've just discovered I have 2 homozygous COMT mutations. Is this Betaine HCL likely to be causing me further problems because of the methyl group(s?) attached to it? I'm completely unable to tolerate any other alternatives (lemon juice, ACV) and I have pretty much non-existent stomach acid production. Even after taking this dose sometimes if a reflux back into my mouth (only happens rarely) it's not acidic at all.
