MOSCOW, 31 Jan. Nutritionist Anastasia Gavrikova told how to determine vitamin B12 deficiency without going to the doctor and taking tests. She noted that many underestimate the importance of B12, which is necessary to maintain a healthy state of nerve cells, improve the function of nerve impulse transmission and normalize the work of the gastrointestinal tract tract.
