High vitamin B12 is a symptom of an underlying illness that causes the amount in your blood to increase. For example, a damaged liver may release the vitamin out of storage and into the blood. In early stages, illnesses associated with high vitamin B12 often have generic symptoms, such as fatigue and loss of appetite.itamin B12 does not accumulate to toxic levels. Consuming large quantities does not cause side effects or high levels in your system, whether you get it through food or from taking high-dose supplements.
Certain vitamins can harm you when taken in excess, specifically fat-soluble vitamins like A and K which will build up in your fat stores. Vitamin B12, however, is water soluble and will be flushed out in your urine if taken in excess. Therefore, there are no vitamin B12 overdose symptoms. The recommended daily dose is very low, about 2-3Âµg, yet many supplements deliver hundreds or thousands of Âµg per dose. This is no mistake.
