Vitamin B12 is a water soluble vitamin that helps to increase energy, assists in the formation of red blood cells and supports cardiovascular health. Vitamin B12 is stored in the kidneys, liver and other body tissues and as a result, the signs and symptoms of vitamin B12 deficiency may not show themselves until 5-6 years of poor dietary intake. The classic symptom of vitamin B12 deficiency is anemia; however it appears that a deficiency will affect the brain and nervous system first. This can lead to impaired nerve function such as a feeling of numbness, a pins and needles sensation as well as mental function.
