It does sound contradictory I know. But my husband has so many symptoms that indicate he's B12 deficient - peripheral neuropathy, orthostatic tremor, wide based gait and imbalance, IBS, tinnitus - also quite withdrawn and depressed. But his blood tests results were about 2000! Surely this indicates some sort of issue with B12. He doesn't have anything wrong with his liver either.
Doc is naturally not taking it very seriously as the levels aren't low.
Can anyone advise?
