which supplement targets methane producing bacteria?

the reason to post it is that I've just googled some of my bloating & constipation symptoms that I've been facing for a long time and it seems like methane producing bacteria is what is actually causing it for me, my digestion has just been really slow and nothing has really helped. has anyone here found something that specifically targets this

out of the supplements I've tried so far emma relief seems to be the only one that's helped, but really want to know if anyone else has found something that works for this specific issue.
