Been giving this to my daughter. Suppose to be two gummy’s but been giving her just one. It is expensive but well worth it. It has been helping her calm down,more alert,clear minded,no meltdowns/behavioral issues,but missed giving her one yesterday and she started having behaviors. So I definitely noticed a difference in her when she takes it. She just turned 14 years old. 👍🏻 I did give her two today and it is helping a lot more with two.
