To the Editor.
The report by Haslam et al,1 purporting to have demonstrated megavitamin therapy to be of no value in treating hyperactivity, and even to have produced mild adverse side effects, received wide media coverage. This is regrettable, because Haslam et al used a very incomplete version of megavitamin therapy.
Haslam et al claimed to have followed the regimen of Cott2 but failed, without mentioning the omission, to use the 25 mg/d of the B complex and 200 mg/d of magnesium that Cott advocates.
