Dr Michael Lyons MD wrote a book called healing the hyperactive brain. In that book he talks a lot about the use of natural supplements to treat ADHD. He recommended the use of ginkgo biloba, Canadian ginseng and essential fatty acids. He recommended dosages in the book – I can’t recall and I lost my copy of the book. He didn’t recommend a product that combined all three. He spoke of buying all three seperately . They seem to be products that are commonly carried in better health food stores. He had used the combination with patients and found it to be helpful. Some people were able to come off the stimulant medication totally and others reduced the medication.
