Vitamin B12 is one of the micronutrients essential for the life of human beings. Although, this vitamin is only found in specific food groups, for which some people could become deficient in vitamin B12 when choosing a specific type of diet.

This vitamin is also known as cobalamin and can be stored in the liver for years. Among the main functions of this micronutrient in the body, the production of red blood cells stands out and it is beneficial for cell growth and division. In addition, it is also involved in the formation of DNA and RNA.

On the other hand, vitamin B12 participates in the metabolism of homocysteine, which is a potentially dangerous amino acid for the cardiovascular system. Having adequate levels of this vitamin helps prevent cardiovascular problems.

And it is that vitamin B12 is mainly found in foods of animal origin, such as meat, fish, liver, crustaceans, or products derived from milk. For this reason, it is common for people who choose a vegetarian or vegan philosophy of life to lack this micronutrient.

In this sense, people with vitamin B12 deficiency have the possibility of supplementing their diet with vitamin supplements. Although, this type of treatment should always have the supervision of a medical specialist.

The first thing to keep in mind is that vitamin B12 is not toxic to the body, even if it is consumed in large quantities. However, different types of people have suffered side effects from the intake of this micronutrient.

One of the ways to get the vitamin into the body due to a significant deficiency is through an injection. While some people who have received a vitamin B12 injection have been able to develop side effects such as insomnia, heart palpitations, hives, itchy skin, or anxiety.

However, doctors understand that these reactions are more associated with the preservatives in the injection formula than the vitamin itself. Therefore, it is much more advisable to take it orally.

On the other hand, people with allergies to cobalt or cobalamin could also develop side effects.

In this case, it is more appropriate to consume foods rich in vitamin B12 and avoid taking capsules or vitamin supplements. The use of supplements is also not advisable for people with Leber’s disease.

Risks of vitamin B12 deficiency

In any case, we must be clear that generally, the excess of vitamin B12 does not cause major complications in the body. However, the problem comes when there is a deficit of this micronutrient.

Generally, the most common symptoms from a lack of vitamin B12 are numbness and tingling of the arms and legs; disorientation, memory problems, movement difficulties, dementia, and mood swings.

In addition, prolonged deficiency of vitamin B12 in the body can be detrimental to DNA synthesis, causing the formation of large and immature red blood cells. All of this can lead to a serious illness such as megaloblastic anemia.

Thus, to avoid a lack of vitamin B12, it is important to have a balanced diet, which regularly includes foods of animal origin, such as different types of meat and fish.
