Vitamin B12 Deficiency

Vitamin B12 Deficiency and Its Effects

When the level of vitamin B12 in the body falls, the resulting condition is called B12 deficiency. This deficiency can lead to irreversible neurological problems. The human body can store vitamin B12 and use it for four years, excreting the excess through urine.

Vitamin B12 is especially necessary for nervous system health, brain function and red blood cell production. It also plays an important role in DNA synthesis, fatty acid metabolism and the utilization of amino acids. Vitamin B12, also known as cobalamin, is one of the body’s largest and most complex vitamins.

Vitamins are important nutrients that cannot be produced by the body or can be produced in insufficient amounts. It is therefore important to provide the body with adequate amounts of vitamins through a balanced diet and, where necessary, through vitamin supplements.

Vitamin B12 is naturally found in animal products. Therefore, the risk of B12 deficiency can be reduced with a healthy diet. However, individuals who do not consume meat can use industrially produced vitamin B12 supplements produced by bacterial fermentation.

Vitamin B12 is essential for the functioning of almost every cell in the body. It is essential for nervous system health, brain function and red blood cell production. It is also involved in basic processes such as metabolism, energy production and fatty acid synthesis.

Red blood cells are constantly being produced and vitamin B12 plays an important role in this process. If vitamin B12 is deficient, red blood cell production can decrease, leading to anemia.

In general, individuals aged 14 years and older are recommended to consume 2.4 micrograms of vitamin B12 per day. During pregnancy and breastfeeding, this amount is slightly higher. Excessive vitamin B12 intake is generally not harmful, but it is important to consult a doctor before starting any supplements.

Vitamin B12 is found in foods of animal origin such as meat, milk and eggs. Eating these foods is often the best way to avoid B12 deficiency. However, this can be more difficult for those on a vegan diet. Vegans can prevent deficiency with supplements or certain fortified foods that contain vitamin B12.

Vitamin B12 deficiency can negatively affect the nervous system and brain function. It can cause symptoms such as depression, memory problems and fatigue. There may also be symptoms such as loss of appetite, constipation and weight loss. As the deficiency progresses, neurological symptoms such as numbness in the hands and feet and loss of balance may occur.

The risk of vitamin B12 deficiency is higher in individuals who do not consume animal products. In addition, conditions such as pernicious anemia, small intestinal problems, gastritis can also cause deficiency. It is therefore recommended that individuals at risk should consider taking supplements.

Vitamin B12 is a vital nutrient for the body. It is possible to prevent this deficiency with an adequate and balanced diet. In particular, individuals who do not consume foods of animal origin should use appropriate supplements in consultation with their doctor.
