We love these gummy bears! My son, who is such a picky eater, actually asks for these! The taste is fabulous. He has only been taking these for about 2 weeks but everyone around him has noticed how his speech has improved. The way he holds a conversation, answers questions, and pronounces words has definitely changed for the better. While I am not positive it is all due to this product, I am certainly confident it is helping him improve and we will continue to use these.
