It's very hard to find all the information you need in a single source. One of the best I've found is Laura Stevens' book "12 Effective Ways to Help Your ADD/ADHD Child". It makes a good starting point for further reading. I'd also recommend "Excitotoxins" by Russell Blaylock, particularly the Conclusion section towards the back, which contains very specific nutrient recommendations.
You can find the Harvard study at
www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12946241&dopt=AbstractThis is only an abstract of the study, a very brief summary. To get the entire article, you have to contact the Alternative Medicine Review at
www.thorne.com/index.html and they will charge you a whopping $20 for a reprint.
FYI, the list of supplements we use (in addition to the wonderful Feingold Diet) is as follows:
A multi-vitamin which contains trace minerals and 100 IU of vitamin E
A B-complex vitamin called a balanced B-50
600mg of Magnesium (my son weighs 90 pounds, so his target dose is 540mg, and that's as close as I can get)
Omega-3 fish oil, 4 capsules daily, which provide a total of 480mg DHA and 720mg EPA. (There are smaller, more concentrated versions available, but my son does not do well on these. Your child might do fine on them.)
One 500mg capsule of Evening Primrose Oil which contains 50mg GLA.
1 - 2 Tbsp daily of lecithin, a rich source of phospholipids which comprise 25% of our brains, and which are required for construction of the neurotransmitter choline.
2 Tbsp daily of soy protein powder, to provide a wide spectrum of amino acids
Finally, I hesitate to recommend single amino acids because their use can be so touchy and you can end up doing more harm than good. However, we have begun seeing really outstanding results with the use of DMAE (250mg daily). Here is an excerpt from "Excitotoxins" about DMAE:
"In one large study involving behavioral problems in children, it was found that DMAE supplementation reduced hyperactivity, increased attantion span, and reduced irritability in 76% of girls and 66% of boys. It may offer a better alternative than Ritalin in cases of attention deficit disorder."
DMAE stimulates the brain's production of choline. Studies show it also improves memory and improves mood. Because of the research Dr. Blaylock cites, and because we are seeing even further improvement by adding the DMAE, I'd recommend including it in your fistfull of supplements.
Vitamins can be expensive. Before purchasing them at your local health food store, you might want to look on-line. I use
www.herbaladvisor.com and they are super CHEAP and carry pretty much everything you might need.
