My child has ADHD and a sensory processing disorder. We have no idea how much the liquid magnesium was helping until we ran out of it for a week. I now have him on a monthly subscription so that doesn’t happen again. The liquid magnesium helps calm his nervous system and helps with his focus. It is so comforting to know that I can help my child any safe and healthy way without the use of prescription medication. Thank you Brainchild Nutritionals!
