Many parents have reported that, within a few days of starting DMG, the child's behavior improved noticeably, better eye contact was seen, frustration tolerance increased, the child's speech improved, or more interest and ability in speaking was observed.

The DMG is merely a highly concentrated food. It may in fact improve the effectiveness of the B6.
