Recent studies show that around 40% of americans are vitamin B12 deficient.
Vitamin B12 is a water soluble vitamin that helps maintain the health of your nerves, brain, and is responsible for creation of your red blood cells.
A vitamin B12 deficiency long term results in nerve damage and may even lead to paralysis.
Even a mild vitamin B12 deficiency can result in impaired mental function and low energy. Vitamin B12 also plays a role in the formation of red blood cells, so a deficiency can lead to the production of large, immature cells that are unable to properly carry oxygen.
