what is difference between B12 being high and taking B1HDL?

[cmichie]

My husband 75 yrs old has high level of b12 so should he not take any B1 until his B12 comes down? He has atypical parkinson

A high B-12 level is not very common if it is not caused by supplementing. It can also be caused by kidneys that are not effectively excreting B-12, by liver issues and possibly by a specific form of leukemia.

Said was so high that it didn’t have a ready but kidney and liver tests turned out to be good and all blood work normal he had been taking B12 for awhile one a day

What type of b12 had he been supplementing with? If it was cyanocobalamin I think it might not be being utilised properly. It’s synthetic and some people are unable to snip off the cyano part to use the rest. If he takes it again he should try and find a natural sourced methyl and adenosyl cobalamin which can be used more easily.

They said do not take any vitamins for awhile because we were going try B1 thiamin

We still take methylB12. It is different than B1.

They said not take any B1 until it came down which they said tests in months
