To Whom It May Concern: I’m the mother of a six-year-old boy named Christopher, who has a history of hyperactivity and behavioral problems. Christopher is normally a sweet and loving child, but frequently throws tantrums in which he becomes so frustrated and angry that he starts kicking, hitting, biting, clawing, and screaming. These tantrums have often lasted for several hours at a time, sometimes ending only when he becomes completely exhausted and cries himself to sleep. Several people, including a preschool teacher and a clinical psychologist, who examined and evaluated my son, suggested that he be referred to an M.D. to be given Ritalin or some other type of behavior-altering medication. Instead, I took Christopher to Dr. Marcus Ettinger who gave him two nutritional supplements (Min-Chex, a holistic nutritional supplement and ÿ-Aminobutyric Acid [GABA], an amino acid). I administered one capsule each of Min-Chex and GABA per day, the results were amazing! On several occasions, when Christopher began throwing a tantrum, I would hold him down long enough to get him to eat a small amount of food with the supplements mixed in. Within 15 to 20 minutes he would be calm and pleasant. There has not been a single instance when Christopher’s behavior has not improved after he received Min-chex and GABA. Our family members and friends have also commented on the behavioral changes. I’m extremely grateful to Dr. Ettinger for providing a holistic alternative with no harmful side effects.
