Vitamin B-12 is an essential nutrient for the body. A deficiency can cause fatigue, depression and nervous system problems. Vitamin B-12 plays a vital role in the production of DNA and red blood cells. The human body needs a large number of red blood cells to obtain and transport oxygen in the body and keep the organs in good health.

The human body cannot store vitamin B-12, so it is important to eat foods containing vitamin B-12 on a regular basis. Adults need about 2.4 micrograms (mcg) of vitamin B-12 per day. Vitamin B-12 is a water-soluble vitamin found in animal foods, such as: red meat, poultry, eggs, milk, fish. If a person is a vegetarian and does not eat animal products, they will need to obtain B-12 from a vegetarian diet. . Including: cereals, plant dairy products, bread and nutritional yeast. Since vitamin B-12 deficiency has many symptoms in common with other nutritional deficiencies, people may neither notice nor get an accurate diagnosis. Being aware of your physical condition can help feed back to the doctor for treatment. Next, let's take a look at the symptoms that may be caused by vitamin B-12 deficiency.

1. Numbness in limbs

Vitamin B-12 deficiency may cause a "pins and prick" sensation in the hands or feet. This symptom occurs because B-12 plays a vital role in the nervous system, and lack of it can cause nerve conduction problems or nerve damage. In the nervous system, vitamin B-12 helps produce a substance called myelin. Myelin is a protective lipid that protects neurons and helps them transmit sensations. People with vitamin B-12 deficiency may not produce enough myelin to protect their nerves. Without this lipid, nerves may be damaged. Nerve damage can cause local numbness of the body, most commonly numbness of the limbs.

2. Difficulty walking

As the vitamin B-12 is deficient for longer, sustained nerve damage can cause movement problems. Numbness in the limbs can make it difficult to walk without support. They may also experience muscle weakness and weakened reflexes.

3. Pale skin

The skin becomes pale or yellower than normal. This is called jaundice and may be a symptom caused by a lack of vitamin B-12. When the human body cannot produce enough red blood cells, jaundice occurs. The red blood cells circulating under the skin's cortex provide it with its normal color. If there are not enough of these cells, the skin may look pale. Vitamin B-12 plays an important role in the production of red blood cells. Deficiency can lead to insufficient red blood cells or megaloblastic anemia. This type of anemia can also weaken red blood cells, allowing the body to break them down more quickly. When the liver breaks down red blood cells, it releases bilirubin. Bilirubin is a brown substance that can make the skin jaundice-like yellowish.

4. Fatigue

Megaloblastic anemia caused by vitamin B-12 deficiency may lead to fatigue. Without enough red blood cells to carry oxygen around the body, a person will feel extremely tired.
