a vitamin deficiency is a possibility. but given that there are so many other possible causes of numbness some of which can be serious you should see your doctor before assuming it’s a vitamin deficiency. one of the most concerning vitamin deficiencies that can cause numbness is a vitamin b12 deficiency. if you eat meat or other animal products you’re probably getting plenty of this in your diet. however vegans (those who eat no animal products) do have to take extra care to be sure they’re getting vitamin b12 either through fortified foods like cereal or through supplementation. some people also have a medical condition called pernicious anemia that decreases their ability to absorb vitamin b12. your doctor can run tests to see if you may have this condition.
could the numbness in my hands and feet indicate some type of vitamin deficiency?
