Vitamin B12 Deficiency Symptoms: Much More Than Fatigue

Reader Contribution by Kathleen Jade and Nd

Vitamin B12 is best known and most promoted as a cure for low energy, but this vitamin is important for much more than keeping energy levels up. Without enough vitamin B12, you may suffer from everything from depression and memory loss to canker sores and dizziness.

Many people with vitamin B12 deficiency don’t have fatigue. Vitamin B12 plays crucial roles in maintaining the health of your blood cells, digestive system, brain, and nervous system. And while fatigue (due to anemia) is sometimes a symptom, recent research shows that many people have vitamin B12 deficiency without anemia or significant fatigue. Instead, they have vitamin B12 deficiency symptoms that are more related to impairments in the nervous system.

Deficiency symptoms most often caused by impaired nervous system. In the nervous system, vitamin B12 is necessary for the formation of myelin, a whitish insulating sheath around nerve fibers that increases the speed at which impulses are conducted. It is also needed for the production of some neurotransmitters. Vitamin B12 deficiency can therefore result in defective myelin synthesis and neurotransmitter imbalances, leading to a host of mental, emotional, and physical symptoms related to the nervous system.
