Is there any kind of vitamin deficit that affects balance and coordination?

Vitamin B12: Vitamin B12 deficiency is one of the most common vitamin deficiencies and is well known to cause problems with balance and coordination. Of course, there are many other possible causes of these problems, but B12 deficiency should always be considered in anyone with these symptoms.

Uncoordination: I agree with dr. Baker about vitamin B12 deficits and uncoordination -- and would definitely add thiamine to the list. Thiamine deficiency is very common in chronic alcoholics and can cause ataxia (balance and coordination problems), eye movement problems, tremor, inability to learn, memory loss, confusion, and making up stories (confabulation).
