In one study, high amounts of vitamin B6 was more effective than methylphenidate (Ritalin). A healthcare practitioner knowledgeable in nutrition must be consulted when using high amounts of this vitamin. B vitamins , particularly vitamin B6, have also been used for ADHD. Deficient levels of vitamin B6 have been detected in some ADHD patients.160 In a study of six children with low blood levels of the neurotransmitter (chemical messenger) serotonin, vitamin B6 supplementation (15-30 mg per 2.2 pounds of body weight per day) was found to be more effective than methylphenidate (Ritalin®). However, lower amounts of vitamin B6 were not beneficial.161 The effective amount of vitamin B6 in this study was extremely large and could potentially cause nerve damage, although none occurred in this study. A practitioner knowledgeable in nutrition must be consulted when using high amounts of vitamin B6. High amounts of other B vitamins have shown mixed results in relieving ADHD symptoms.162 , 163
