Unwell? Could be an indication of vitamin B12 deficiency
Vitamin B12 plays a key role in maintaining various functions of the human body, and it is essential to a balanced diet.
Also known as cobalamin, it is part of the B-complex and plays a direct role in the formation of blood cells and neurons; it is also very important for maintaining the myelin sheath—the structure that conducts electrical impulses and facilitates communication between neurons.
Vitamin B12 deficiency can cause neurological and hematological (blood-related) complications, as it is responsible for the functioning of various cells and the maintenance of metabolism and the nervous system, in addition to playing a role in DNA synthesis. When it comes to deficiency, a study conducted by the Brazilian Journal of Pathology and Laboratory Medicine estimates that 20% of the population in industrialized countries is deficient in this vitamin.
Although neurological symptoms are the most common, a deficiency of this vitamin can affect other parts of the body, leading to various complications, such as pernicious anemia, gastrointestinal disorders, and even cardiovascular problems.
Not everyone experiences symptoms; many may be asymptomatic and discover the condition after a medical examination. However, in general, symptoms may include paleness and yellowish skin; extreme weakness and fatigue; shortness of breath and dizziness; reduced sense of touch, difficulty walking, and vision problems; as well as loss of appetite and weight loss.
Vitamin B12 can be found in animal-based foods, such as fish, seafood, meat, dairy products, and eggs. It is not found in plant-based foods. For this reason, it is common for vegetarians and vegans to be deficient in this vitamin. However, a deficiency in this vitamin can also be related to age and certain gastrointestinal disorders, such as celiac disease and Crohn’s disease. Infants born to mothers who do not eat meat and people who have undergone gastrointestinal procedures are also at risk.
To find out if you have a vitamin B12 deficiency, you’ll need to have lab tests done. If you’re unsure, consult a healthcare professional for guidance on the best way to take supplements. In fact, thanks to advances in technology, you can now find vegan supplement options that meet your daily needs.
