Ask the doctor: Can vitamin B6 cause tingling?
Q. Is it true that you can get a tingling feeling from taking too much vitamin B6?
A. Vitamin B6 is a water-soluble vitamin that's involved in over 100 different enzyme reactions in the body, many of them involving protein metabolism. Adults need just a small amount — less than 2 milligrams (mg) a day — and a wide variety of foods contain B6, so a reasonably balanced diet provides most people with all they need.
