My daughter has special needs and non-verbal. She's been taking the Brain Booster Duo daily with Matcha. We really see a lot of improvement sa communication and responsiveness nya. She even chooses what breakfast she wants to eat, the clothes she likes to wear and tries to communicate with other people in her own way. So happy that she's consistently improving with the help of this duo! I also take it when I need to focus, this has been a staple in our home!
