There is no published evidence that high B12 levels are harmful.
Most of the people here keep their levels above 1000. There are some at 2000.
I trialed the new Puritan's pride version of methylB12 last year and got test showing 1999 ...mostly to see if the product was
labeled accurately.
The only concern with high B12 serum levels is that it may mislead the doctor, as far as the medical causes for high B12 in the face of NO supplementation. Some kidney disease, liver disease and blood diseases may raise B12 as a warning sign.
If you are using a supplement, a high level is no surprise, however. But in and of itself it is not harmful.
If your scalp pain is better, then try going lower on your dosage and see if you can get by with less. When symptoms return, that will be a sign you need a higher one.
