Hi there,
Thanks for using HCM.

Low vitamin B12 can cause anemia. Anemia in turn can cause tachycardia.
Vegans are more prone for Vitamin B12 deficiency.

Check your serum B12 and hemoglobin levels.
If it is found to be low, then you may needs Vitamin B12 shots.

If you have any more questions, do let me know.

Vitamin B12 shots or Oral tablets help

Hi,
Since your Vitamin B12 level is low, you require Vitamin B12 shots or Oral tablet of Vitamin B12 like Meganeuron. It needs frequent testing and adjusting of dose so please consult a primary care doctor.

On a blood peripheral smear it has large RBC called macrocytic RBC and this is important than hemoglobin level. Up to 28 percent of affected patients may have a normal hemoglobin level, and up to 17 percent may have a normal mean corpuscular volume
