My 7.5 year old has been on Vayarin for a little over 60 days. We just started talking about how everything is clicking all of a sudden for him and realized it must be the Vayarin. He is still a very active kid but it seems like he is focusing more when he needs to. His tutor has also noticed a difference. The medicine says it can take 60-90 days. You also can’t skip it so we have made it part of our bedtime routine.
