You suffer from fatigue, depression, hair loss, dry skin, as well as more serious neurological disorders such as stiff limbs, muscle weakness, difficulty walking and burning in the tongue. Low haemoglobin/anaemia is present. Vitamin b12 deficiency occurs much more than we imagine. We no longer see it only in people on a vegan diet and the elderly. Some medical conditions or some medications can exacerbate the deficiency. In my practice I see such deficiencies very often and after administration mostly by injections, the results and improvement of symptoms are spectacular.
