Unfortunately, there aren't any alternative treatments that work for ADHD. I think every parent of a child with ADHD wishes there was a magic vitamin or diet that would solve it all, but research has proven that's just not the case with this medical condition. You'll end up wasting time and money. The only thing that has shown some promise is omega-3s and even then, people use those with medication and it takes a long time to see any results. A lot of companies are out there banking on parental fears and misinformation about the regulated medications and are profiting on "alternatives" that just don't work.
I urge you to read ADDitude magazine and join CHADD to learn more about ADHD. This is a genetic brain disorder and the reason the government-regulated medications work is that they target the area of the brain that isn't communicating correctly. Please talk over your concerns about medication with the psychiatrist who made the diagnosis. We mentioned every one of our concerns to our son's psychiatrist and got the reassurances we needed to give medication a try. We are so thrilled we did because it transformed his life completely. It connected the dots in his brain and allowed him to function like a regular child. One hundred percent positive. I can't speak highly enough about what medication has done for our son. And we had to make the leap of faith trying meds when he was four, so we were extra scared.
Go to the reliable sources of information about ADHD and be extremely cautious about being scammed with alternatives.
