Top 10 Vitamin B12 Foods

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.

The benefits of vitamin B12 are vast and include:

  • Boosting energy
  • Reducing depression
  • Decrease sugar cravings
  • Lowering cholesterol and blood pressure
  • Protects against cancer
  • Reduces neurological and brain degeneration
