Vitamin B-12, also called cobalamin, is a water soluble vitamin that plays a key role in the formation of blood (red blood cells and white blood cells), normal functioning of the brain and nervous system. Vitamin B-12 is one of the eight B vitamins, and it is involved in the metabolism of every cell in the human body. Vitamin b-12 functions as a cofactor for methionine synthesis and L-methylmalonyl-CoA mutase.
Vitamin B-12 is bound to protein in food, commonly found in fish, shellfish, meat, eggs and dairy products. The Vitamin B-12 is then released in the stomach by hydrochloric acid during digestion. Vitamin B-12 is then coupled with a component in the stomach called intrinsic factors (IF) before it is released and absorbed into the bloodstream within the small intestine.
WHY SHOULD I GET MY VITAMIN B-12 LEVEL CHECKED?
The benefits of knowing your Vitamin B-12 levels are vital since they play a major role in the formation of blood cells and functioning of the brain and nervous system. Vitamin B-12 deficiency may be due to multiple causes such as dietary deficiency, pernicious anemia, post-surgical malabsorption, and atrophic gastritis, a condition that affects 10 – 30% of the elderly population.
Vitamin B-12 deficiency may show up in multiple symptoms, including fatigue, weakness, loss of appetite and constipation. Symptoms such as numbness and tingling of the hands and feet may be experienced in severe deficiencies.
Having an optimal Vitamin B-12 level can help you regain your energy, increase your metabolism, regulate your immune system and support your nervous system.
