The idea to take GABA was a natural ADD treatment we read about in this book:
Healing ADD: The Breakthrough Program that Allows You to See and Heal the 7 Types of ADD
Recently, studies have indicated that enhancing GABA activity may be beneficial in improving mental performance in children and may also be helpful in treating ADD and promoting better brain and mental health at all ages. Low levels or decreased GABA function in the brain is associated with several psychiatric and neurological disorders, but most primarily anxiety, depression, insomnia, and epilepsy. But rather than rely on drugs to accomplish this goal, a natural form of GABA known as PharmaGABA may be the best approach. (you want to avoid dangerous synthetic GABA) PharmaGABA is naturally manufactured via a fermentation process that utilizes Lactobacillus hilgardii—the bacteria used to ferment vegetables in the preparation of the traditional Korean dish kimchi.
A study was conducted in Japan by researchers from the Kyorin University Medical School, which involved 60 sixth graders. The students were divided into two groups and received either 100 mg of PharmaGABA or a placebo. The students then took a math test and were also evaluated for signs and feelings of stress. The results were quite dramatic. The average number of answers given by the PharmaGABA group was 20 percent higher than the placebo group, and the number answered correctly also increased by 20 percent. These results indicate that Pharma-GABA helped the kids not only think faster, but also get more answers right.
We found a whole 250mg tablet is too much (and it seems to give him nosebleeds) so I use a pill cutter, and give him only a half tablet, every night before bed. (I have also tried it – GABA is relaxing, and helps me sleep better by calming the mind.)
