Vitamin B12 is found naturally in foods of animal origin, including foods, fish, poultry, eggs and dairy products. It is also found in products enriched with vitamin B12, such as certain varieties of herbal bread and milk. Vitamin B12 is a nutrient that contributes to the health of nerves and blood cells in the body and the production of DNA, which is the genetic material of all cells. Vitamin B12 helps prevent anemia called megaloblastic anemia that makes people tired and weak.
A person needs vitamin B12 for many important bodily processes, especially to make red blood cells and preserve the nerves.
According to Bupa, when there is a lack of vitamin, the body produces fewer red blood cells, it will be abnormally large and will not last as long as they should.
When a person does not have enough red blood cells, his tissues and organs may not have enough oxygen.
This leads to symptoms of anemia, which develop when the blood lacks enough healthy red blood cells or hemoglobin.
Symptoms of vitamin B12 deficiency may include weakness, fatigue, lightheadedness, heart palpitations, pale skin, and smooth tongue.
Another symptom is that the body may lack vitamin B12 and lies in sleep patterns.
According to a study by the National Institutes of Health in the United States, vitamin B12 deficiency can affect a person's sleep-wake rhythm.
The study focused on two patients suffering for many years from different sleep-wake disorders.
Both patients received vitamin B12 and were monitored over a period of time. The study concluded that vitamin B12 improved their sleep-wake rhythm disorder.
The study showed that a lack of vitamin B12 could hinder sleep patterns.
If you think your vitamin B12 is deficient, it is important to talk to your doctor.
Vitamin B12 deficiency is usually treated with vitamin B12 supplementation.
Bupa said, "This could include a series of injections given once a week for six weeks.
"After that, you may need to take repeated doses every three months or so.
Your doctor will monitor you to make sure your treatment is working Soon after you start your treatment, you will be asked to have a blood test after about eight weeks to confirm that your hemoglobin and red blood cell count has returned to normal. "
