I have rated this product with 3 stars because i am finding it hard to administer. The capsules are too big for my son so i pierce them and squeeze onto a spoon. The goo inside is too thick so there is a sizeable amount left on the spoon so i think he is getting a smaller dose. Its not child friendly basically. My husband is more impressed than me but i have to say my boy has more awareness than before. I cant explain it but its small changes that if you blink you miss them but his brain seems to be functioning better. So all in all it was worth it!!
