I just started my 9 year old son on Daily Essential Nutrients by Hardy Nutritionals after learning about Julia Ruckledges' research on nutrition and brain function. She wrote a book called The Better Brain. We've only been using the supplements for 3 weeks and so far I don't notice much change, but the recommendation is to use them 3-6 months before assessing effectiveness.
My kiddo also takes two ADHD meds (stimulant and anxiety). I'm really struggling to keep hope that we will be able to find something that will help my son and just wanting to hear from other parents about their experiences (positive or not) with these supplements for treating ADHD symptoms.
