I bought it for my 5 year old daughter who has Down syndrome and autism, this product is really working, she is calmer during the day, the therapists have praised its performance in therapies. She is also sleeping better. As my daughter still doesn't chew it, I crush it and mix it with a little water and give it to her on a spoon. The taste is good, because she accepts it without any problems.
I hope it continues to work, for now I'm very satisfied.
