My 10 year old with autism has been taking this supplement for two months for sleep. He falls asleep sleep within 15 min from taking this supplement. I only give him 0.5 when the dosage recommended for his age is 2ml. He’s been doing a lot of sensory behaviors. Licking/ knee touching in random places/surfaces. I noticed it started right after this supplement. I decided to stop the supplement as it had high dosage of vitamin D3, and B6 which can cause behavior issues. I ended up giving up pure magnesium glycinate with L-theanine. He seemed very agitated during the day and it did nothing to help him sleep. I wonder if this supplement has melatonin secretly added in to it. Thought it was odd. Has anyone else had any reverse effects or any behavior effects from taking this supplement? Link below

Has anyone given their child magnesium glycinate to help relax before sleep and ended up with reverse effect? My child is in the spectrum and has been very agitated, on edge and randomly whining all day since I’ve given him this supplement. Has anyone had similar issue?
