When vitamin B 12 is dangerous, and when it is necessary

As well as other useful substances, the body needs vitamin B 12. It provides the accumulation of energy necessary for life, promotes cell multiplication, supports the normal functioning of the immune system.

If we do not get enough of it with food if the absorption of the vitamin is impaired (for example, large amounts of vitamin C can disrupt the production of B12 with food), if the patient is over 50 years of age and the digestion is disrupted due to age-related changes, then you need to ask for Help to medicine. Start taking the medicine "Cyanocobalamin." Realized vitamin B 12 in ampoules for intramuscular, subcutaneous and intravenous injections, in the form of a crystalline powder of red color and in the form of tablets, capsules.

Vitamin B 12 is found in foods mainly of animal origin: liver, meat, fish, eggs, milk, cheese, herring, oysters. But there are also in plant foods: sea kale, soy, yeast. A small piece of fish (for example, salmon) would be enough to compensate for the need for vitamin for 3 days.

To psychological manifestations include: fatigue, irritability, drowsiness, depressive state, persistent dizziness, headaches, ringing in the ears, and with severe hypovitaminosis there can be even hallucinations and loss of memory. All this can be accompanied by the application of significant harm to the nervous system (without the vitamin, the protective shell of nerves collapses). Scientists noted an increased risk of heart disease and Alzheimer's disease even with a small B12 deficiency.

Dosage

Vitamin B 12 in tablets is produced both separately and as part of multivitamin complexes. Its content in dietary supplements and biocomplexes is sufficient for a healthy adult. Therapeutic doses are hundreds of times higher.

In the form of injections, according to the prescription of the doctor, 0.1 or 0.2 mg is administered (in severe cases, 0.4 or 0.5 mg) every other day, since vitamin B 12 has the property of accumulating in the body.

In the form of powder, it is poorly digested, so it is recommended to take with folic acid. Long-term administration together with potassium (as well as with corticosteroid hormones and neuroleptics) will lead to a course of vitamin treatment to zero.

Overdose is very dangerous: up to anaphylactic shock. Side effects are also unpleasant: dizziness, pain, allergy, tachycardia. Do not take risks without clear instructions from your doctor. However, this advice does not apply to the intake of vitamin in the biocomplex.
