There are alternatives besides Zetia, like bempodoic acid. I supplemented with b12 when I developed this small fiber neuropathy because I was vegan, so it was not a b12 deficiency. It's definitely a cause for some people. I would like to get my LDL a bit lower, so I am thinking of trying a supplement containing plant sterols (like cholestoff). I hope that you can find an alternative that does well for you.
