Vitamin B12 Injections Benefits

What Is Vitamin B12?

Vitamin B12, or cobalamin, is part of the group of so-called water-soluble vitamins, those that cannot be accumulated in the body, and which must be regularly consumed through food.

What Is Vitamin B12 Used For?

Vitamin B12 plays an essential role in red blood cell production and bone marrow formation. It is also involved in the metabolism of amino acids, nucleic acids - like folic acid, it assists in the synthesis of DNA and RNA - and in fatty acids.

Vitamin B12 Requirements

Having a deficiency of vitamin B12 is a very common disorder, especially among people subject to alterations in the acidity of the digestive tract, in those who frequently undergo antibiotic treatments and who follow a vegetarian or vegan diet.

To make up for this lack, vitamin B12 injections are often used. It is a therapy capable of remedying all the symptoms related to the deficiency of this nutrient, which include weakness, bad mood and difficulty concentrating.

Cases of severe deficiencies, on the other hand, can interfere with the formation of red blood cells and raise homocysteine levels, which can cause negative effects on neurological and cardiovascular health.

Several foods provide a good dose of B12, but some people have a diet that does not allow them to ingest all foods or have difficulty absorbing this nutrient, generally due to metabolic changes.

In these cases, vitamin B12 injections provide the right help.

What Are Vitamin B12 Injections?

Injections of B12 help to rapidly increase the levels of this substance in our body. Vitamin B12 is required for the proper performance of many vital metabolic and hormonal functions, including the production of enzymes essential for digestion and transporting nutrients in and out of cells.

Symptoms Of Vitamin B12 Deficiency

Indicative signs and symptoms of a B12 deficiency include:

- Chronic fatigue and weakness

- Pain in muscles and joints combined with difficulty in carrying out physical exercises

- Poor memory and difficulty concentrating

- Depression, anxiety or other signs of nervousness such as palpitations and tachycardia

- Oral cavity problems, including gum bleeding

- Feeling short of breath

- Constipation, nausea, diarrhoea or stomach cramps

Is It True That Those Who Follow A Vegan Diet Run The Risk Of Vitamin B12 Deficiency?

Yes, it's true. Vitamin B12, or cobalamin, is not contained in doses adequate to human needs in any plant or vegetable existing in nature. Therefore, those who eat only plant-based foods could present the symptoms caused by a deficiency of this vitamin.

Benefits Of Vitamin B12 Injections

They reduce depression and cognitive decline: Some scientific studies have shown that, especially with advancing age, supplementing with vitamin B12 can prevent depression and keep the vital functions of the brain active.

They manage muscle weakness: Getting vitamin B12 to the right levels can effectively treat anaemia, aid in the conversion of macronutrients and in the production of creatine, one of the building blocks of muscle mass. In this way, chronic fatigue and weakness in muscle tone can be managed.

They improve metabolism: Some people resort to vitamin B12 injections to counteract a slow metabolism and manage weight gain. Since this therapy can give patients more energy and regulate hormone production, after treatment it is possible to experience changes in appetite, increased sleep quality and improved athletic performance.

They protect the heart: Elevated levels of homocysteine in the blood are a risk to cardiovascular health. Vitamin B12 is necessary for its conversion and, therefore, for the prevention of heart disease.

Is Vitamin B12 Safe?
