i

Vitamin B12 is an essential nutrient that our body requires for different functions, including production of energy, synthesis of DNA (Deoxy Nucleic Acid), proper functioning of the CNS (central nervous system) and so on. Despite the common presence of Vitamin B12 in different food sources, the deficiency of the vitamin has been found to be quite prevalent in many individuals. The are many reasons behind this, some of them are poor dietary intake of Vitamin B12, oral intake of Vitamin B12 depleting medicines, and malabsorption of the vitamin in the body.

According to some studies, it has been found that almost more than 20% of people from the United States and United Kingdom suffer from Vitamin B12 deficiency leading to different signs and symptoms. As an individual grows old, the capability to absorb vitamin B12 from the food decreases and that is why the deficiency is commonly found in older adults.

The deficiency of vitamin B12 is often misdiagnosed due to the lack of symptom specificity or unavailability of proper testing. Whatever the reason, the deficiency can lead to many signs and symptoms that might affect the health of the individuals drastically.
