Vitamin B12 (cobalamin) is a vital substance that participates in many important functions of the body. It plays a significant role in the formation of blood cells, DNA synthesis, maintaining nervous system health, and energy production.
B12 vitamin is often not given enough attention, which can lead to serious and irreversible consequences over time.
Why is B12 vitamin necessary?
This water-soluble vitamin is primarily found in animal products (meat, fish, eggs, and dairy products). In the body, it is absorbed in the small intestine, a process facilitated by an intrinsic factor produced in the stomach.
Main functions of B12 vitamin:
- It forms blood cells and protects against anemia.
- It supports the myelin sheath of nerve fibers, ensuring proper signal transmission.
- It participates in DNA synthesis and energy metabolism processes.
Risks of B12 deficiency:
If vitamin deficiency is not treated, it can lead to the following serious consequences:
- Nerve damage: pain, loss of balance, weakness, and in severe cases, paralysis.
- Dementia and brain atrophy: increases the risk of Alzheimer's disease.
- Anemia: large and insufficient blood cells (megaloblasts).
- Increased homocysteine levels: risk of cardiovascular diseases.
- Mental disorders: depression, anxiety, and psychosis.
What to do?
If you notice symptoms, consult a doctor. Proper nutrition, taking vitamin supplements, or B12 injections can help eliminate the deficiency.
