How can you tell if you are B12 deficient?

[Rasel Ali (IT)]

Vitamin B12 belongs to the B group of vitamins. B vitamins are very important to the body, especially vitamin B12.



The main physiological functions of vitamin B12 are to prevent pernicious anemia, participate in the production of bone marrow red blood cells and maintain the health of the nervous system.

The body needs very little vitamin B12, and the recommended daily amount of vitamin B-12 for adults is about 2.4 micrograms.

Once the human body lacks B12 vitamin, it may cause many clinical symptoms, such as anemia, nausea, vomiting, anorexia, weakness, fatigue, heart palpitations, shortness of breath, pale skin, nerve damage, mood disturbances and so on.

Vitamin B12 is generally stored in the liver for a long time, and the total is only about 2 mg to 3 mg.

If not supplemented with new vitamin B12, the stored vitamin B12 can still meet the body requirements for 3 to 5 years.

As long as you eat a balanced diet, you will not be deficient in vitamin B12. In general, dairy products, eggs, fish, meat, poultry and animal offal, etc., are rich in vitamin B12.
