A water soluble vitamin that is involved in metabolism is vitamin B12 or cobalamin. The vitamin B12 plays an important role in nervous system maintenance. It is noteworthy that vitamin B12 helps in myelin sheath formation. That is a protective sheath around the nerves. By this, there would be nerve transmission. Nerve damage would occur due to the vitamin B12 deficiency. The vitamin B12 also plays its role in the production of red blood cells in the bone marrow. The deficiency of vitamin B12 must be considered seriously and must be treated well. The deficiency of this vitamin would be shown by various signs in us.
There are some unusual signs of vitamin B12 deficiency and these are
Tingling or numbness:
