“Otherwise, serious health problems can knock on your door,” Dr. said, noting that vitamin B12, which is not produced in the body, must necessarily be taken from outside through nutrients.

In these days, when the pandemic continues, a balanced intake of vitamins and minerals is essential for a strong immunity.

Vitamin B12, which is especially vital, is a guarantee of our health, said a professor of Internal Medicine Dr. explained what needs to be known about it as follows:


Almost the only nutritional element that is not found in animal products is vitamin B12. Lack of vegans (strict vegetarians) who consume no animal products is common. B12 deficiency is not seen in vegetarian diets because they consume milk, yogurt, eggs. In addition, in general, today’s diet consists of foods that are weak in terms of vitamin B12. Stomach diseases and drugs such as cancer-ulcers prevent the absorption of this vitamin, causing B12 deficiency. Again, drugs such as metformin, used to treat diabetes and obese people with insulin resistance, lead to vitamin B12 deficiency. Alcohol consumption is also among the causes of B12 deficiency.


Modern agricultural practices, such as overuse of pesticides, intensive exposure of soils to artificial fertilizers, and failure to rest soils, have led to the disappearance or reduction of many bacterial species that live in soils and synthesize vitamin B12. Apart from Modern agricultural practices, many additives have been added to it, many vitamins and minerals in packaged foods, as well as vitamin B12 are extremely low. Natural, unprocessed and whole plant foods are the most valuable sources of vitamins.


B12 deficiency can be understood by a simple blood test. Its treatment is in the form of pills or injections (intramuscularly). Vitamin B12 is one of the drugs that is used unnecessarily and whose use is abused. ”It strengthens the brain“,” it is good for dementia“,” it prevents strokes” and it is necessary to stay away from B12 drugs that are used unnecessarily. This situation is unnecessary and inconvenient.


The most important symptoms that emerged in B12 deficiency: anemia, glossitis (tongue inflammation), fatigue, forgetfulness, lack of concentration, decrease in intellectual capacity, insomnia, dizziness, balance disorder, numbness in the hands and feet tingling, loss of appetite, dementia, Alzheimer’s, coronary heart disease symptoms (chest pain, shortness of breath), insulin resistance, obesity, and lemon-yellow pallor to the one who stole.
