Vitamin B12: Sources, Daily Requirement, Deficiency

          Vitamin B12



• Vitamin B12 is essential for the body to function properly. Therefore, it is important to regularly incorporate these nutritional vitamins into our nutritional structure through certain foods. 

• This vitamin, also known as cyanocobalamin, is stored primarily in the liver and has important functions in the body. For example, it is involved in the formation of red blood cells and in the production of DNA, the genetic material found in all cells. 

• Vitamin B12 is also beneficial for maintaining the nervous system and preventing diseases such as megaloblastic anemia. 

• Thus, one of the most amazing properties of vitamin B12 is that it is only found in animal products such as meat, fish, seafood, eggs, or dairy products. It is currently not found that herbal products contain this vitamin in their ingredients.

• Finding out if our body is deficient in vitamin B12 is not easy. However, when a person lacks this trace element for a long time, the body tends to warn about the situation through various symptoms. Therefore, with prolonged deficiency of this element, the most common symptoms are weakness, blurred vision, constant fatigue, memory loss, and numbness of the arms and legs.

Daily Requirement of Vitamin B12:

Adults (ages 19–64) need about 1.5 mcg of vitamin B12 per day. Vitamin B12 is not found in foods such as fruits, vegetables, and whole grains, and vegans may not get enough of it.

However, prolonged deficiency of this vitamin can lead to serious health problems such as heart failure and megaloblastic anemia. It can also cause cognitive impairment. Therefore, in such cases, it is customary to prescribe drugs that increase the level of this vitamin in the body. It is best to quickly relieve the situation with a vitamin B12 injection.


Health Benefits of Vitamin B12

Vitamin B12 is essential for the proper functioning and development of the brain, nerves, blood cells and other parts of the body.

1. Vitamin B12 is essential for energy production

Vitamin B12 helps the body metabolize proteins and fats and convert carbohydrates into sugars that the body can use for energy. Because of this, people with B12 deficiency often feel tired and tired. It also supports myelin, an insulator of fatty nerves that is important for the nervous system, and optimizes brain signals by causing muscles to contract when needed.

2. Vitamin B12 improves brain function and mood

The nervous system benefits of B12 also extend to the brain. Vitamin B12 is key to the formation of mood-enhancing serotonin and dopamine and may help relieve symptoms of depression and anxiety. When combined with folate found in dark green leafy vegetables, it triggers the release of S-adenosylmethionine, or SAM, a compound that helps manage stress and regulate mood. B12 is also important for maintaining concentration, memory, and concentration.

3. Vitamin B12 protects you from heart disease

It's okay, but B12 will protect you. It increases blood levels of the amino acid homocysteine, which protects against cardiovascular nausea such as heart attacks and strokes. It also prevents anemia by helping the production of red blood cells, which carry oxygen throughout the body. Without proper treatment, your muscles will become weak, you will feel short of breath and your workout will be difficult. Don't confuse this feeling with a lack of sleep.

4. Vitamin B12 improves sleep

You may have a B12 deficiency. The vitamin not only increases the production of melatonin, the sleep hormone that regulates circadian rhythm, but also promotes its early release, that is, throughout earlier nights.

5. Vitamin B12 keeps hair and skin healthy

It's not just about bodily functions. B12 also invests in a fresh look. Vitamins are important for shiny hair, healthy nails and acne-free skin because they play a huge role in cell renewal. If you have psoriasis and eczema, B12 can help reduce redness, dryness, itching, and inflammation.
