In this way, the symptoms can be varied: neurological disorders (limb numbness, coordination and memory impairment), deficiency of red blood cells (anemia, fatigue, decreased immunity and muscle strength), hormonal disorders (repercussions psycho-emotional, nervousness, depression, loss of libido, etc.), digestive problems (diarrhea, constipation, mouth ulcers, etc.). After all, only a blood test can detect a vitamin B12 deficiency for sure. The larger the deficit, the more severe the symptoms.
Vitamin B12 and food
Vitamin B12 is provided by the diet. It is found especially in organ meat and to a lesser extent in milk (and some cheeses) and eggs. In case of severe deficiency, a person can also take vitamin B12 nutritional supplements. The doses will then be 1000 µg daily before gradually reducing them. According to the WHO, the preferred form is hydroxocobalamin, which is a natural vitamin B12.
