__//**Definition:**//__ Vitamin B12, also called cobalamin is a water soluble that is known to play a big role in neurology.

B12 also maintains the myelins sheath that insulates neurons.

Known to be the most largest and structurally complicated vitamin. B12 can be produced industrially only through a bacterial fermentation synthesis.

__//**Rankings:**//__ Safety:5/5 Effective:4/5 Ease of Use: 4/5 Even though they are drops and take about 15 seconds, people may not enjoy the taste of the supplement due to the 15 second wait in the mouth. It depends on what brand you plan on purchasing and if the supplement has other ingredients in the product. Cost:4/5 Even thought vitamin B12 is a supplement we need, the pricing on the supplement ranges from $10-$30. I personally believe $30 is a little too much especially if many elderly are in the need of the supplement. Total:17/20
