Description
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.
