Hi. For info on DMG(Dimethylglycine) you can visit the Autism Research Institute website at [url="http://www.autism.com."]www.autism.com.[/url] I have been giving it to my 3.5 year old ASD son for over a year, and I have seen very positive results in better attention, focus, and his all around health.
He was forced to go without it for a few weeks over the xmas holidays when my supplier ran out, and his attention went down hill and some old stims(eye-stimming) that had dissappeared, returned. It took a month to get the DMG back into his system, and my son back to the way he was before. It had taken a month to take effect when we first started. I hope this helps.
