Vitamin B12 is red crystalline powder, odorless and tasteless, slightly soluble in water and ethanol.
Vitamin B12 is the only vitamin that contains metal elements. Vitamin B12 is also the only vitamin that requires the help of an intestinal secretion to be absorbed.
It is involved in making bone marrow red blood cells, preventing pernicious anemia, and preventing damage to nerves in the brain.
