Great.
I bought this vitamins for my 10yr old child who has Tourette's syndrome and I saw improvement on his ticks in about 2 weeks. Unfortunately I ran out of pills and the next bottle took almost a month to arrive (nothin to do with the company it was the carrier due to the holidays). I finally received the next bottle and I feel like the we are back to square one but he has show improvement and we are very hopeful and excited to see what this vitamins can contribute to him in the long run.
Between I learned my lesson so now I order the vitamins in advance, I already have the 3rd bottle on the way.
Last but not least let me just mentioned the amazing costumer service the have woow! They call you, text you, email, you. They make sure your questions are answered and they are super nice and professionals. Hands down best customer service I have encounter.
Thank you!
