Vitamin B12 is a vital nutrient due to its effects on major functions of the body, and its ability to restore your energy. A deficiency of vitamin B12 can result in multiple health problems and cause a lack of energy in general. We will look at vitamin B12 benefits and functions, as well as symptoms of deficiency, absorption, and drug interactions.
Blood Cell Production
Vitamin B12 is necessary for proper formation of red blood cells. When formed correctly, red blood cells are small and round, but a lack of vitamin B12 causes them to be larger and more oval and causes anemia.
Bone Health
People who have a vitamin B12 deficiency tend to have a lower than normal bone mineral density, making bones more fragile and delicate. Osteoporosis can happen as a result.
Mood and Brain Health
Vitamin B12 is important for synthesis and metabolism of serotonin, a chemical produced by your body to regulate mood. A B12 deficiency can lead to lower serotonin production and cause a depressed mood. In addition, vitamin B12 is partially responsible for the strength of the myelin sheath that surrounds nerve cells and determines how quickly messages are communicated to your brain.
Energy
Vitamin B12 is involved in the metabolism of carbohydrates, proteins, and fats. When there are inadequate amounts of B12 in your system, you cannot properly convert these to restore your energy.
Supplementing with Vitamin B12
Vitamin B12 is not produced by your body, and therefore has to be obtained via a diet rich in meats, fish, poultry, eggs, and dairy products. When adequate amounts of B12 are not absorbed through the diet due to poor absorption rates or a vegan diet, it may be necessary to supplement your diet with synthetic vitamin B12 either orally, by inhalation, or through injections.
