The benefits of DMAE bitartrate are being researched for the treatment of Alzheimer's disease and other age-related brain disorders. The results are still inconclusive, but for ADHD, the results are more promising. For example, there are many studies that showed ADD children that supplemented with DMAE bitartrate versus a placebo, scored a lot higher on cognitive tests. This is attributed to the mental enhancing effects that were mentioned earlier in this article. One interesting thing to note is that DMAE used to be a prescription during the 1980's. 

 If you do decide to supplement with DMAE, the recommended dosages are between 400 and 1,800 mg daily. Personally, I would use this nutrient with other vitamins/herbs to help create a synergistic effect. Combining DMAE bitartrate with choline, ginseng, and ginkgo are excellent combinations, but it can be tiresome and redundant to buy these ingredients separately and take 10 pills per day.
