Helps Boost the Immune System
Vitamin B12 helps maintain the immune system’s healthy function and may reduce the risk of infections. It is essential for immune system maintenance. Red blood cells transport oxygen to the body tissue, which is vital for healthy immune system function. Red blood cell synthesis depends on vitamin B12, ensuring the immune system receives the oxygen it requires. Because of this, a B12 shortage might interfere with the complex immunological processes, decreasing the body’s resistance to disease.
The immune system is a complex system made up of numerous organs, white blood cells, proteins (antibodies), and chemicals. Together, these components of the body’s defense system guard against external invaders like bacteria, viruses, parasites, and fungi that cause infections and lead to disease.
The immune system can be damaged or disrupted by various deficiencies and diseases. For example, some medications hinder the body’s ability to fight infection. In addition, certain medical problems make it difficult for the immune system to defend the body against harmful pathogens or cause it to target healthy cells. These include allergies, auto-immune disorders like lupus and rheumatoid arthritis, infections like HIV or mononucleosis, and sepsis. Certain cancers, such as leukemia and lymphoma, may also weaken the immune system.
