vitamin B12 deficiency in people over the age of 50



Vitamin B12 is one of the most important B vitamins that plays an important role in the production of energy and red blood cells. Vitamin B12 is the only water-soluble vitamin stored in the liver and found only in animal food sources such as meat, so vegetarians are prone to vitamin B12 deficiency.

The role and function of vitamin B12 in the human body:

Vitamin B12 is essential for the production of red and white blood cells, hemoglobin, platelets and other components of the blood, and its deficiency can cause severe anemia and other blood diseases. Red blood cells, platelets and many other blood components are produced in the bone marrow, the activity of the bone marrow is highly dependent on a sufficient amount of vitamin B12.



Vitamin B12 is needed to produce RNA and DNA and to record genetic information and the growth of cells in the body.

Vitamin B12, along with folic acid and vitamin B6, reduce the amount of the amino acid homocysteine ​​in the blood. Research shows that high homocysteine ​​increases the risk of miscarriage in pregnant women and cardiovascular disease in other people.

Vitamin B12 plays a vital role in the activity of the brain, central nervous system, as well as the maintenance of the covering of nerve fibers called myelin, and its deficiency with severe neurological reactions such as confusion, memory loss, depression, Imbalance when walking and associated with symptoms such as MS.

The body uses vitamin B12 to convert the enzyme L-Methylmalonyl-CoA to Succinyl-CoA, a reaction essential for the conversion of fats and proteins into energy. With this mechanism, vitamin B12 speeds up the body's metabolism and energy and improves system function. It is digested.



Symptoms and problems associated with vitamin B12 deficiency

Serious diseases and problems caused by vitamin B12 deficiency are some of them:

Anemia: Vitamin B12 deficiency reduces the body's ability to produce red blood cells and hemoglobin and causes anemia. In a CBC blood test, low levels of hemoglobin (HB) and red blood cells (RBCs) can be signs. Vitamin B12 deficiency, as well as vitamin B12 and folic acid deficiency, cause abnormal increases in the size of red blood cells, as shown by MCV tests.

Decreased Mind and Memory Efficiency: Vitamin B12 deficiency is associated with side effects associated with decreased brain efficiency, such as memory loss, forgetfulness, depression, confusion, and confusion.



Damage to the central nervous system and nerve fibers (myelin): As mentioned, vitamin B12 is essential for maintaining the health of the nerve fibers, and in the absence of this vitamin, the nerve fibers are damaged and symptoms such as MS occur. کردن.

Decreased energy, extreme tiredness, numbness and burning sensation in the hands and feet, nerve problems, muscle weakness, dizziness are other symptoms of vitamin B12 deficiency.

How much vitamin B12 should we get daily?

Adults over the age of 19 need 2.4 micrograms of vitamin B12 daily, pregnant women 2.6, and lactating women 2.8 micrograms of vitamin B12 per day, and the daily requirement for children and adolescents is about 1 microgram per day. B12 is recommended.

Vegetarians are at risk for vitamin B12 deficiency.

Also, with age, the absorption of vitamin B12 through the gastrointestinal tract decreases, and it is recommended that people over the age of 50 and vegetarians receive this vitamin through dietary supplements or injections.

Liver problems, alcohol consumption, heavy menstruation in women, bleeding for any reason, aspirin use increase the body's need for vitamin B12.



Food sources of vitamin B12

Red meats, especially mutton, beef and chicken, fish, chicken, cooked oysters, eggs, and some cheeses are good sources of vitamin B12.

In many countries, some popular foods such as cornflakes, milk, fruit yogurts, etc. are fortified with vitamin B12.

Dietary supplements and ampoules of vitamin B12

Vitamin B12 supplements are produced and supplied in different doses with and without other B vitamins.

Injectable ampoules of vitamin B12 are also available in doses of 100 and 1000 micrograms. Because ampoules and vaccines contain some mercury or aluminum metal, which is harmful to the body, I think taking vitamin B12 supplements is better than using their injectable form, and only ampoules should be used for some people. Who have difficulty absorbing this vitamin through the gastrointestinal tract.

If you have high blood pressure, kidney disease, heart disease and other specific diseases, be sure to consult your doctor before taking vitamin B12 supplements.

Excess vitamin B12 is rare because the body can easily excrete it in the urine, but like other vitamins, vitamin B12 supplements should not be taken in excess without a doctor's daily requirement.

A blood test can measure the amount of vitamin B12 in the body.
