Common symptoms of Vitamin B12 deficiency
Why is vitamin B12 so important?
Vitamin B12 comes from the B group of vitamins. Unlike most other vitamins, however, it can neither be produced in, or stored by your body, and therefore can only be absorbed through certain foods, or health supplements. Vitamin B12 is an important nutritional requirement for the body as it aids in the production of red blood cells, protects the nerves from damage and ensures structural stability of certain chromosome regions, apart from being able to also carry out other bodily functions. The human body is capable of producing millions of red blood cells every minute. However, this process can only be made possible if there is an adequate supply of vitamin B12 to carry oxygen throughout the body. Contrastingly, a vitamin B12 deficiency can lead to physical and psychological problems in the body. The symptoms of a vitamin B12 deficiency include impaired vision, mouth ulcers, irritability and depression.
Important facts to know about Vitamin B12
A Vitamin B12 deficiency typically affects anywhere between 1.5 and 15 percent of people. Given the fact that vitamin B12 cannot be stored by your body, it therefore needs to be provided on a daily basis through certain foods, or a health supplement. For example, adults between the age of 19 – 64 need approximately 1.5 microgram (mcg) of vitamin B12 per day. Foods that double up as natural sources of vitamin B12 include fish, meat, eggs and dairy products.
