My 10 year old daughter was diagnosed with ADD in 2013. She was taking Quillivant for a year and a half. She complained of not feeling her happy self and she felt shaky often in school. She lost an extreme amount of weight and was petite before she lost weight. I took her off of the Quillivant and tried her on MesoGold. She began taking 1 tbsp in the morning 15 min before breakfast. She now takes it at lunch as well. Her grades have improved, she is now an honor roll student. The main difference is she is not struggling for those grades. Before taking MesoGold it would take her hours to complete her homework. She is now very organized and has her work done ahead of time because it is no longer a huge project to do it. MesaGold has been a life changer for her.
