In some studies, taking vitamin B6 along with other nutrients appeared to prevent the development of tardive dyskinesia. During a ten-year period, doctors at the North Nassau Mental Health Center in New York treated approximately 11,000 people with schizophrenia with a megavitamin regimen that included vitamin C (up to 4 grams per day), vitamin B3 -either as niacin or niacinamide-(up to 4 grams per day), vitamin B6 (up to 800 mg per day), and vitamin E (up to 1,200 IU per day). During that time, not a single new case of TD was seen, even though many of the people were taking neuroleptic drugs.269 Another psychiatrist who routinely used niacinamide , vitamin C, and vitamin B-complex over a 28-year period rarely saw TD develop in her patients.270 Further research is needed to determine which nutrients or combinations of nutrients were most important for preventing TD. The amounts of niacinamide and vitamin B6 used in this research may cause significant side effects and may require monitoring by a doctor.
