Re: Dosage for three years old with ADHD?

The B complex that I have contains 80 mg of B6, so I'm giving her about 160mg a day.

I did some googling and I found the following:

"Vitamin B6
B vitamins, particularly vitamin B6, have also been used for ADHD. Deficient levels of vitamin B6 have been detected in some ADHD patients.38 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.39 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.40, 41"


The amount suggested by this study is 225mg of vit B6 for my daughter I don’t think I'm going to up the dose but I'm not sure if 160mg that I'm giving her is safe or not, any thoughts?
