Vitamin B12: essential to avoid deficiencies but often neglected

Vitamin B12, or cobalamin, is crucial for health and well-being. Yet many people don't realize the importance of maintaining adequate levels of this essential vitamin. In this article, find out everything you need to know about vitamin B12, its benefits, its signs of deficiency and how AJY, the French brand of food supplements, can help you.

Why is the absorption of vitamin B12 so important for our body?

Role of vitamin B12 in the body

Vitamin B12 is essential for many functions in our body. It contributes to the formation of red blood cells, supports the proper functioning of the nervous system and participates in the metabolism of proteins and fats.

Causes of vitamin B12 deficiency

Vitamin B12 deficiency can result from a variety of factors, including an unbalanced diet, gastrointestinal disorders, or specific dietary choices like vegetarianism or veganism.

Unbalanced diet

A diet low in animal products, the main source of vitamin B12, is a common cause of deficiency. This is especially true for those who avoid these products altogether, such as strict vegetarians and vegans.

Gastrointestinal disorders

Diseases that affect the digestive system, such as celiac disease, Crohn's disease or atrophic gastritis, can reduce the ability of the intestine to absorb vitamin B12. Additionally, with age, stomach acid production decreases, which can also affect vitamin B12 absorption.

Certain medications

Certain medications, such as proton pump inhibitors or antacids, can reduce the absorption of vitamin B12. This is why it is always recommended to discuss with a healthcare professional when taking such medications, especially if it is prolonged.

Signs that you have vitamin B12 deficiency

Persistent fatigue

One of the most common symptoms of vitamin B12 deficiency is fatigue. Without enough of this vitamin, your body has difficulty producing the energy it needs to function properly.

Neurological problems 

Tingling or numbness in the hands and feet, unsteadiness when walking, and decreased concentration can all be indicators of a lack of vitamin B12.

Megaloblastic anemia

Vitamin B12 is essential for the formation of red blood cells. A deficiency can therefore lead to a form of anemia where the blood cells produced are larger than normal.

Vision problems

Severe vitamin B12 deficiency can affect vision by damaging the optic nerve.

Palpitations and shortness of breath

These symptoms may result from an inability to produce enough healthy red blood cells.

How to prevent and treat vitamin B12 deficiency? Food supplements: an effective solution

For those who cannot or do not wish to consume these products, dietary supplements are an excellent alternative.

Why is vitamin B12 so important for our body?

Vitamin B12, often referred to as the "energy vitamin," is crucial for the proper functioning of virtually every cell in the human body. Ranging from energy production to DNA synthesis, its role is central in our health. But what exactly are the functions and impacts of this vitamin?

Role of vitamin B12 in the body

Energy and metabolism

Vitamin B12 plays a crucial role in the transformation of carbohydrates into glucose, used by the body as an energy source. Thus, an adequate intake of vitamin B12 helps reduce fatigue and boost metabolism, ensuring constant energy throughout the day.

Nervous health

Vitamin B12 is essential for maintaining a protective sheath around nerves called myelin. This protection is crucial to prevent neurological disorders and ensure optimal functioning of the nervous system. Additionally, vitamin B12 helps in the production of neurotransmitters, facilitating communication between neurons.

Formation of red blood cells

Vitamin B12 actively supports the production of red blood cells, thus preventing megaloblastic anemia. A good amount of red blood cells is essential for efficient transport of oxygen throughout the body, ensuring good circulation and healthy heart function.

Bone health

Studies have shown that people with a vitamin B12 deficiency are more likely to suffer from bone problems, such as osteoporosis. An adequate intake of vitamin B12 therefore contributes to bone density and the prevention of fractures.

Macular degeneration prevention

Vitamin B12 may play a role in preventing age-related macular degeneration (AMD), a condition that affects central vision. Combined with other B vitamins, B12 may reduce the risk of developing this eye disease.

Support for mood and mental system

It is well established that vitamin B12 contributes to mood regulation. Vitamin B12 deficiencies have been linked to mood disorders like depression. Ensuring optimal levels of this vitamin helps maintain good mental health and regulate neurotransmitters responsible for emotional well-being because a deficiency in vitamin B12 increases the risk of depression.
