Unwell? Could be an indication of vitamin B12 deficiency
Vitamin B12 plays a fundamental role in maintaining various functions in the human body and its presence is indispensable in a balanced diet.
Also known as cobalamin, it is part of the B complex and is directly involved in the formation of blood cells and neurons, and is very important for maintaining the myelin sheath - the structure that conducts electrical impulses and integrates communication between neurons.
B12 deficiency can cause neurological and hematological (blood) complications, as it is responsible for the functioning of various cells and maintaining metabolism and the nervous system, as well as taking part in DNA synthesis. When it comes to deficiency, a study carried out by the Brazilian Journal of Pathology and Laboratory Medicine estimates that 20% of the population in industrialized countries are deficient in the vitamin.
Although neurological manifestations are predominant, a deficiency of this vitamin can affect other parts of the body, resulting in various complications, such as pernicious anemia, gastrointestinal dysfunctions and even cardiovascular problems.
Not everyone has symptoms, many may be asymptomatic and discover the deficiency after a medical investigation. But in general, symptoms can include pallor and yellowish skin; extreme weakness and fatigue; shortness of breath and dizziness; reduced sense of touch, walking and vision problems, and lack of appetite and weight loss.
Vitamin B12 can be found in foods of animal origin, such as fish, seafood, meat, dairy products and eggs. It has not been found in foods of plant origin. For this reason, it is common for vegetarians and vegans to be deficient in this vitamin. However, a lack of this vitamin can also be related to age and certain diseases of the gastrointestinal tract, such as celiac disease and Crohn's disease. Babies of mothers who don't eat meat and people who have undergone gastrointestinal procedures are also at risk.
To find out if you are deficient in vitamin B12, you need to take laboratory tests. If you're in doubt, seek the advice of a professional to recommend the best form of supplementation. In fact, with advances in technology, you can find vegan supplement options that meet your daily needs.
