My son is 5 1/2 and on the Mega Vitamin Therapy and doing awsome!! I was reading about SerenAid the enzyme blend and I am interested in trying it but I would like to hear from other parents that are useing/have used it. Does it do what it claims too? Has anyone noticed any changes in your child? Are there any side effects? I have read all the pharmecy and doctor reports but parents tend to be a lot more honest. He takes so many vitamins already I feel guilty for even thinking of asking him to take something else. Thank you for your time.
