Vitamin B12 is reduced and converted in the body to two active coenzyme forms, deoxyadenosylcobalamin and methylcobalamin. Deoxyadenosylcobalamin is required for hydrogen transfer and isomerization of methylmalonyl CoA to succinyl Co A. This reaction is involved in both fat and carbohydrate metabolism.

Is 1000mcg too much B12?
In one 8-week study in 100 older adults, supplementing with 500 mcg of vitamin B12 were found to normalize B12 levels in 90% of participants. Higher doses of up to 1,000 mcg (1 mg) may be necessary for some ( 10 ).

Is B12 level of 1500 too high?
There is no consensus on the definition of high or elevated B12. Previous studies have chosen a variety of levels to represent high or very high B12 (pmol/l) levels. Some examples include: 664.219; 5131; 700 (high) and 1500 (very high)11; and 601 (high) and 1000 (very high)10.
How much vitamin B12 is in a shot?
B12 shots contain about 100 micrograms of B12, which is roughly 40 times the recommended daily value for an average healthy adult (2.4 micrograms). But these high doses are necessary to help treat people with a deficiency.
Is B12 level of 1200 too high?
The normal range for vitamin B12 (total) is between 200 – 1100 ng/L (nanograms per liter), 200 – 1100 pg/mL (picograms per milliliter), or 148 – 811 pmol/L (picomoles per liter). The normal range for active vitamin B12 (holoTC) is around 20 – 134 pmol/L (picomoles per liter).
What level of B12 is dangerously high?
An abnormally high vitamin B-12 status is anything over 900 pg/mL. This result may suggest liver or kidney problems, diabetes, or certain forms of leukemia.

Elevated levels of serum cobalamin may be a sign of a serious, even life-threatening, disease. Hematologic disorders like chronic myelogeneous leukemia, promyelocytic leukemia, polycythemia vera and also the hypereosinophilic syndrome can result in elevated levels of cobalamin.
Is 500 a good B12 level?
The vitamin B12 standard reference range is 200–700 pg/ml whereas the proposed optimal range is 500–1300 pg/ml [10]. Higher vitamin B12 ranges have been associated with increased cognitive function, and reflexes, decreased brain atrophy, confusion, weakness and depression [10].
