Vitamin B12 is important because it helps to keep the body's nerve and blood cells stay healthy. According to Dr. Adarsh Vijay Mudgil, M.D., owner of Mudgil Dermatology in New York, a vitamin B12 deficiency can cause neurological issues like numbness. It can also lead to tingling in the hands, legs, and feet, tiredness, weakness, difficulty walking, and anemia. You can easily get more vitamin B12 in your system by consuming meat, eggs, poultry and dairy. Strict vegetarians and vegans are at a higher risk for developing a deficiency, so taking a supplement or eating grains fortified with the vitamin could be beneficial for them.
